- BACKGROUND: Clinical equipoise exists regarding optimal sequencing in the definitive management of choledocholithiasis. Our current study compares sequential biliary ductal clearance and cholecystectomy at an interval to simultaneous laparoendoscopic management on index admission in a pragmatic retrospective manner.METHODS: Records were reviewed for all patients admitted between January 2015-December 2018 to a Swedish and an Irish university hospital. Both hospitals differ in their practice patterns for definitive management of choledocholithiasis. At the Swedish hospital, patients with choledocholithiasis underwent laparoscopic cholecystectomy with intra-operative rendezvous ERCP at index admission (one-stage). In contrast, interval day-case laparoscopic cholecystectomy followed index admission ERCP (two-stage) at the Irish hospital. Clinical characteristics, post-procedural complications, and inpatient duration were compared between cohorts.RESULTS: Three hundred and fifty-seven patients underwent treatment for choledocholithiasis during the study period, of whom 222(62.2%) underwent a one-stage procedure in Sweden, while 135(37.8%) underwent treatment in two stages in Ireland. Patients in both cohorts were closely matched in terms of age, sex, and pre-operative serum total bilirubin. Patients in the one-stage group exhibited a greater inflammatory reaction on index admission (peak C-reactive protein = 136±137 vs. 95±102mg/L,p=0.024), had higher incidence of co-morbidities (age-adjusted Charlson Comorbidity Index ≥3:37.8% vs 20.0%,p=0.003), and overall were less fit for surgery (ASA ≥3: 11.7% vs. 3.7%,p < 0.001). Despite this, a significantly-shorter mean time to definitive treatment, i.e., cholecystectomy (3.1±2.5 vs. 40.3±127 days,p=0.017), without excess morbidity, was seen in the one-stage compared to the two-stage cohort. Patients in the one-stage cohort experienced shorter mean post-procedure length of stay(3.0±4.7 vs 5.0±4.6 days,p < 0.001) and total length of hospital stay(6.5±4.6 vs 9.0±7.3 days,p=0.002). The only significant difference in postoperative complications between the cohorts was urinary retention, with a higher incidence in the one-stage cohort (19% vs. 1%, p=0.004).CONCLUSION: Where appropriate expertise and logistics exist within developing models of Acute Care Surgery worldwide, consideration should be given to index-admission laparoscopic cholecystectomy with intraoperative ERCP for the treatment of choledocholithiasis. Our data suggest this strategy significantly shortens the time to definitive treatment, decreases total hospital stay without any excess in adverse outcomes.

- Abdominal compliance (AC) is an important determinant and predictor of available workspace during laparoscopic surgery. Furthermore, critically ill patients with a reduced AC are at an increased risk of developing intra-abdominal hypertension and abdominal compartment syndrome, both of which are associated with high morbidity and mortality. Despite this, AC is a concept that has been neglected in the past. AC is defined as a measure of the ease of abdominal expansion, expressed as a change in intra-abdominal volume (IAV) per change in intra-abdominal pressure (IAP): AC = Delta IAV/Delta IAP AC is a dynamic variable dependent on baseline IAV and IAP as well as abdominal reshaping and stretching capacity. Whereas AC itself can only rarely be measured, it always needs to be considered an important component of IAP. Patients with decreased AC are prone to fulminant development of abdominal compartment syndrome when concomitant risk factors for intra-abdominal hypertension are present. This review aims to clarify the pressure-volume relationship within the abdominal cavity. It highlights how different conditions and pathologies can affect AC and which management strategies could be applied to avoid serious consequences of decreased AC. We have pooled all available human data to calculate AC values in patients acutely and chronically exposed to intra-abdominal hypertension and demonstrated an exponential abdominal pressure-volume relationship. Most importantly, patients with high level of IAP have a reduced AC. In these patients, only small reduction in IAV can significantly increase AC and reduce IAPs. A greater knowledge on AC may help in selecting a better surgical approach and in reducing complications related to intra-abdominal hypertension.

- BACKGROUND: Several retrospective clinical studies and recent prospective animal models demonstrate improved outcomes with beta-blocker administration after isolated blunt head injury. However, no investigations to date have examined the influence of race on the potential therapeutic effectiveness of these medications. Our hypothesis was that mortality benefits associated with beta-blocker exposure after isolated blunt head injury varies based on ethnicity.METHODS: The trauma registry and the surgical intensive care unit (ICU) databases of an academic Level I trauma center were used to identify all patients sustaining blunt head injury requiring ICU admission from July 1998 to December 2009. Patients sustaining major associated extracranial injuries (Abbreviated Injury Scale [AIS] score ≥3 in any body region) were excluded. Patient demographics, injury profile, Injury Severity Score, and beta-blocker exposure were abstracted. The primary outcome evaluated was in-hospital mortality stratified by ethnicity.RESULTS: During the 11-year study period, 3,750 patients were admitted to the Los Angeles County + University of Southern California Medical Center trauma ICU because of blunt trauma. Of these, 65% (n = 2,446) had an “isolated” head injury. When stratified by race, most patients were Hispanics (60%), followed by Whites (21%), Asians (11%), and African Americans (8%). After adjusting for confounding variables with multivariate regression, only those of Asian and Hispanic descent demonstrated significantly improved outcomes associated with beta-blocker administration.CONCLUSIONS: Our results indicate that beta-blockade after traumatic brain injury may not benefit all races equally. Further prospective research is necessary to assess this discrepancy in treatment benefit and explore other possible therapeutic interventions.LEVEL OF EVIDENCE: III, therapeutic study; II, prognostic study.

- BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an emergency procedure that is potentially lifesaving in major noncompressible torso hemorrhage. It may also improve outcome in nontraumatic cardiac arrest. However, the procedure can be technically challenging and requires the immediate presence of a qualified operator. Thus, evidence-based training and assessment of operator skills are essential for successful implementation and patient safety. A prerequisite for this is a valid and reliable assessment tool specific for the procedure. The aim of this study was to develop a tool for assessing procedural competence in REBOA based on best-available knowledge from international experts in the field.METHODS: We invited international REBOA experts from multiple specialties to participate in an anonymous three-round iterative Delphi study to reach consensus on the design and content of an assessment tool. In round 1, participants suggested items to be included. In rounds 2 and 3, the relevance of each suggested item was evaluated by all participants to reach consensus. Interround data processing was done systematically by a steering group.RESULTS: Forty panelists representing both clinical and educational expertise in REBOA from 16 countries (in Europe, Asia, and North and South America) and seven different specialties participated in the study. After 3 Delphi rounds and 532 initial item suggestions, the panelists reached consensus on a 10-item assessment tool with behaviorally anchored rating scales. It includes assessment of teamwork, procedure time, selection and preparation of equipment, puncture technique, guidewire handling, sheath handling, placement of REBOA catheter, occlusion, and evaluation.CONCLUSION: We present the REBOA-RATE assessment tool developed systematically by international experts in the field to optimize content validity. Following further studies of its validity and reliability, this tool represents an important next step in evidence-based training programs in REBOA, for example, using mastery learning.

- BACKGROUND: Valid and reliable assessment of skills is essential for improved and evidence-based training concepts. In a recent study, we presented a novel tool to assess procedural skills in resuscitative endovascular balloon occlusion of the aorta (REBOA), REBOA-RATE, based on international expert consensus. Although expert consensus is a strong foundation, the performance of REBOA-RATE has not been explored. The study aimed to examine the reliability and validity of REBOA-RATE.METHODS: This was an experimental simulation-based study. We enrolled doctors with three levels of expertise to perform two REBOA procedures in a simulated scenario of out-of-hospital cardiac arrest. Procedures were video-recorded, and videos were blinded and randomized. Three clinical experts independently rated all procedures using REBOA-RATE. Data were analyzed using Messick's framework for validity evidence, including generalizability analysis of reliability and determination of a pass/fail standard.RESULTS: Forty-two doctors were enrolled: 16 novices, 13 anesthesiologists, and 13 endovascular experts. They all performed two procedures, yielding 84 procedures and 252 ratings. The REBOA-RATE assessment tool showed high internal consistency (Cronbach's alpha = 0.95) and excellent interrater reliability (intraclass correlation coefficient, 0.97). Assessment using one rater and three procedures could ensure overall reliability suitable for high-stakes testing (G-coefficient >0.80). Mean scores (SD) for the three groups in the second procedure were as follows: novices, 32% (24%); anesthesiologists, 55% (29%); endovascular experts, 93% (4%) (p < 0.001). The pass/fail standard was set at 81%, which all experts but no novices passed.CONCLUSION: Data strongly support the reliability and validity of REBOA-RATE, which successfully discriminated between all experience levels. The REBOA-RATE assessment tool requires minimal instruction, and one rater is sufficient for reliable assessment. Together, these are strong arguments for the use of REBOA-RATE to assess REBOA skills, allowing for competency-based training and certification concepts.

- BACKGROUND: To determine the frequency and characteristics of prehospital deaths compared with hospital deaths in different subpopulations with severe injuries.METHODS: Population-based cohort study using person-based linkage of the Swedish nationwide hospital discharge register with death certificate data. In all, 28,715 injury deaths were identified among 419,137 cases of severe injury during 1998 to 2004. Prehospital deaths were defined as autopsied out-of-hospital deaths with injury as the underlying cause. Their impact on mortality prediction was assessed using the International Classification of Disease Injury Severity Score with the C statistic as a measure of discrimination.RESULTS: The majority of all injury deaths occurred either at the scene or before hospitalization. Among persons younger than 65 years, for each hospital death there were nine prehospital deaths. A high proportion of deaths from drowning, suffocation, and firearm injuries were prehospital (85, 82, and 67% of all cases, respectively). More than 90% of hospital deaths resulted from unintentional injuries, while only 43% of prehospital deaths were unintentional. The largest increase in a cause-specific case fatality risk estimate was seen for poisoning, where inclusion of prehospital deaths increased the risk estimate from 1.6% to 22.8%. Injury mortality prediction based on International Classification of Disease Injury Severity Score improved when prehospital deaths were added to hospital data (C statistic increased from 0.86 to 0.93).CONCLUSIONS: Prehospital deaths constitute the majority of trauma deaths and differ in major characteristics from hospital deaths. The high proportion of prehospital deaths among young and middle aged people highlights the potential impact of preventive efforts.

- BACKGROUND Cardiopulmonary resuscitation (CPR), although lifesaving may cause chest wall injury (CWI) because of the physical force exerted on the thorax. The impact of CWI on clinical outcome in this patient group is unclear. The primary aim of this study was to investigate the incidence of CPR-related CWI and the secondary aim to study injury pattern, length of stay (LOS), and mortality in patients with and without CWI. METHODS This is a retrospective study of adult patients who were admitted to our hospital due to cardiac arrest (CA) during 2012 to 2020. Patients were identified in the Swedish CPR Registry and those undergoing CT of the thorax within 2 weeks after CPR were included. Patients with traumatic CA, chest wall surgery prior or after CA were excluded. Demographic data, type and length of CPR, type of CWI, LOS on mechanical ventilator (MV), in intensive care unit (ICU) and in hospital (H), and mortality were studied. RESULTS Of 1,715 CA patients, 245 met the criteria for inclusion. The majority (79%) of the patients suffered from CWI. Chondral injuries and rib fractures were more common than sternum fractures (95% vs. 57%), and 14% had a radiological flail segment. Patients with CWI were older (66.5 ± 15.4 vs. 52.5 ± 15.2, p < 0.001). No difference was seen in MV-LOS (3 [0-43] vs. 3 [0-22]; p = 0.430), ICU-LOS (3 [0-48] vs. 3 [0-24]; p = 0.427), and H-LOS (5.5 [0-85] vs. 9.0 [1-53]; p = 0.306) in patients with or without CWI. Overall mortality within 30 days was higher with CWI (68% vs. 47%, p = 0.007). CONCLUSION Chest wall injuries are common after CPR and 14% of patients had a flail segment on CT. Elderly patients have an increased risk of CWI, and a higher overall mortality is seen in patients with CWI. LEVEL OF EVIDENCE Prognostic and Epidemiological; Level IV.

Tidskriftsartikel (refereegranskat)abstract
- The Walker Dip refers to the cycle of the improvement of care for the battle injured soldier over the course of a conflict, followed by the decline in the skills needed to provide this care during peacetime, and the requisite need to relearn those skills during the next conflict. As the operational tempo of the conflicts in Afghanistan and Iraq has declined, concerns have arisen regarding whether US military surgeons are prepared to meet the demands of future conflicts. This problem is not unique to the US military, and allied nations have taken creative steps to address the Walker Dip in their own surgical communities. A panel entitled "Military and Civilian Trauma System Integration: Where Have We Come; Where Are We Going and What Can We Learn from Our International Partners" at the 2018 American Association for the Surgery of Trauma meeting brought together a cadre of civilian and military surgeons with experience in this area. The efforts described involved the creation of a new trauma training program in Doha, Qatar, the military civilian partnership in the Netherlands, and the steps taken to address the deficit of penetrating trauma in Sweden. This article focuses on the lessons that can be learned from our allied partners to assure readiness for deployment among military surgeons.

- BACKGROUND: The plasma concentration of natriuretic peptide type B (BNP) or NT-proBNP (P-BNP or P-NT-proBNP) reflects cardiac load. In intensive care unit settings and in chronic inflammation, it is also affected by non-heart-related mechanisms. It has been suggested to be a marker of hydration after severe burns and to predict outcome in critically ill patients, but results are contradictory. We therefore measured P-NT-proBNP after severe burns and related it to injury related variables and to organ dysfunction. less thanbrgreater than less thanbrgreater thanMETHODS: Fifty consecutive patients with a burn size greater than 10% were studied for the first 2 weeks. P-NT-proBNP changes were analyzed in relation to burn size, age, changes in body weight, C-reactive protein in plasma, and organ function assessed as Sequential Organ Failure Assessment (SOFA) scores less thanbrgreater than less thanbrgreater thanRESULTS: P-NT-proBNP showed large day-to-day and between patient variations. Daily change in body weight correlated with P-NT-proBNP only on Day 2, when maximum mobilization of edema occurred. Thereafter, P-NT-proBNP correlated with C-reactive protein in plasma as well as with SOFA scores. Burn size correlated with maximal weight change, which in turn correlated with both time for and value of maximum P-NT-proBNP. Maximal P-NT-proBNP was related to mortality and correlated better with SOFA score on Day 14 compared with age and burn size. In linear regressions, together with age at injury and total body surface area, P-NT-proBNP assessed on Days 3 to 8 was an independent predictor for every subsequent SOFA score measured one or more days later up to Day 14. less thanbrgreater than less thanbrgreater thanCONCLUSION: P-NT-proBNP exhibited considerable interindividual and day-to-day variations. Values were related to mortality, burn size, water accumulation, posttraumatic response, and organ function. Maximum P-NT-proBNP correlated stronger with length of stay and with organ function on Day 14, compared with age and burn size. High values in Days 3 through 8 were also independent predictors of subsequent organ function up to 2 weeks after injury. (J Trauma Acute Care Surg. 2013;74: 855-861.

- Food withdrawal 24 hr before hemorrhage has been shown to increase experimental post-hemorrhage mortality, and survival is associated with the degree of hyperglycemia. Lack of hyperglycemic response has been attributed to depleted glycogen reserves after 24-hr food withdrawal. To investigate the effect of short-term food deprivation on glucose metabolism during hemorrhagic stress, glucose production (rate of appearance, Ra), glucose uptake (rate of disappearance, Rd), glucose clearance, and glucose recycling were investigated in fed and 24-hr food-deprived rats under basal conditions, and during hemorrhagic hypotension using 3-H3-U-C14-glucose. During hemorrhage, blood glucose levels were higher in fed rats. Hemorrhage induced a decrease in glucose clearance irrespective of nutritional state in both 24-hr starved animals and rats in the postprandial state. Calculated glucose recycling increased in both groups after hemorrhage. The results indicate that hemorrhagic stress induces a rapid increase in gluconeogenesis, as reflected by increased glucose recycling.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Approximately 20% to 40% of trauma survivors experience posttraumatic stress disorder (PTSD). The American College of Surgeons Committee on Trauma reports that early screening and referral has the potential to improve outcomes and that further study of screening and intervention for PTSD would be beneficial. This prospective randomized study screened hospitalized patients for traumatic stress reactions and assessed the effect of a brief intervention in reducing later development of PTSD.METHODS: The Primary Care PTSD (PC-PTSD) screen was administered to admitted patients. Patients with symptoms were randomized to an intervention or control group. The brief intervention focused on symptom education and normalization, coping strategies, and utilizing supports. The control group received a 3-minute educational brochure review. Both groups completed in-hospital interviews, then 45- and 90-day telephone interviews. Follow-up collected the PTSD checklist-civilian (PCL-C) assessment and qualitative data on treatment-seeking barriers.RESULTS: The PC-PTSD screen was successful in predicting later PTSD symptoms at both 45 days ( = 0.43, p < 0.001) and 90 days ( = 0.37, p < 0.001) even after accounting for depression. Correlations of the intervention with the PCL-C scores and factor score estimates did not reach statistical significance at either time point (p = 0.827; p = 0.838), indicating that the brief intervention did not decrease PTSD symptoms over time. Of those at or above the PCL-C cutoff at follow-ups, a minority had sought treatment for their symptoms (43.2%). Primary barriers included focusing on their injury or ongoing rehabilitation, financial concerns, or location of residence.CONCLUSION: The PC-PTSD screen identified patients who later assess positive for PTSD using the PCL-C. The brief intervention did not reduce 45- and 90-day PTSD development. Follow-up interviews revealed lack of treatment infrastructure in the community. It will be important for trauma centers to align with community resources to address the treatment needs of at-risk patients.

- BACKGROUND: Serious complications related to groin access have been reported with the use of resuscitative endovascular balloon occlusion of the aorta (REBOA). We performed a systematic review and meta-analysis to estimate the incidence of complications related to groin access from the use of REBOA in adult trauma patients.METHODS: We identified articles in MEDLINE and EMBASE. We reviewed all studies that involved adult trauma patients that underwent the placement of a REBOA and included only those that reported the incidence of complications related to groin access. A meta-analysis of proportions was performed RESULTS: We 13 studies with a total of 424 patients. REBOA was inserted most commonly by trauma surgeons or emergency room physicians. Information regarding puncture technique was reported in 12 studies and was available for a total of 414 patients. Percutaneous access and surgical cutdown were performed in 304 (73.4%) and 110 (26.5%) patients respectively. Overall, complications related to groin access occurred in 5.6% of patients (n=24/424). Lower limb amputation was required in 2.1% of patients (9/424), of which three cases (3/424 [0.7%]) were directly related to the vascular puncture from the REBOA insertion. A meta-analysis which used the logit transformation showed a 5% (95% CI 3%-9%) incidence of complications without significant heterogeneity (LR test: χ2 = 0.73, p=0.2, Tau-square=0.2). In a second meta-analysis, we used the Freeman-Turkey double arcsine transformation and found an incidence of complications of 4% (95% CI 2%-7%) with low heterogeneity (I2 = 16.3%).CONCLUSION: We found that the incidence of complications related to groin access was of four to five percent based on a meta-analysis of 13 studies published worldwide. Currently, there are no benchmarks or quality measures as a reference to compare, and thus, further work is required to identify these benchmarks and improve the practice of REBOA in trauma surgery.LEVEL OF EVIDENCE: Systematic Review and Meta-analysis, Level III.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: An association between beta-blocker (BB) therapy and a reduced risk of major cardiac events and mortality in patients undergoing surgery for hip fractures has previously been demonstrated. Furthermore, a relationship between an increased Revised Cardiac Risk Index (RCRI) score and a higher risk of postoperative mortality has also been detected. The purpose of the current study was to investigate the interaction between BB therapy and RCRI in relation to 30-day postoperative mortality in geriatric patients after hip fracture surgery.METHODS: All patients over 65 years of age who underwent primary emergency hip fracture surgery in Sweden between January 1, 2008 and December 31, 2017, except for pathological fractures, were included in this retrospective cohort study. Patients were divided into cohorts based on their RCRI score (RCRI 1, 2, 3, and ≥ 4) and whether they had ongoing BB therapy at the time of admission. A Poisson regression model with robust standard errors of variance was used, while adjusting for confounders, to evaluate the association between BB therapy, RCRI, and 30-day mortality.RESULTS: A total of 126,934 cases met the study inclusion criteria. Beta-blocker therapy was associated with a 65% decrease in the risk of 30-day postoperative mortality in the whole study population [adj. IRR (95% CI): 0.35 (0.32-0.38), p < 0.001]. The use of BB also resulted in a significant reduction in 30-day postoperative mortality within all RCRI cohorts. However, the most pronounced effect of beta-blocker therapy was seen in patients with an RCRI score greater than 0.CONCLUSIONS: Beta-blocker therapy is associated with a reduction in 30-day postoperative mortality, irrespective of RCRI score. Furthermore, patients with an elevated cardiac risk appear to have a greater benefit of beta-blocker therapy.LEVEL OF EVIDENCE: Level II, Therapeutic / Care Management.

- BACKGROUND: Timely management is critical for treating symptomatic common bile duct (CBD) stones; however, a single optimal management strategy has yet to be defined in the acute care setting. Consequently, this systematic review and network meta-analysis, comparing one-stage (CBD exploration or intraoperative endoscopic retrograde cholangiopancreatography [ERCP] with simultaneous cholecystectomy) and two-stage (precholecystectomy or postcholecystectomy ERCP) procedures, was undertaken with the main outcomes of interest being postprocedural complications and hospital length of stay (LOS).METHODS: PubMed, SCOPUS, MEDLINE, Embase, and Cochrane Central Register of Controlled Trials were methodically queried for articles from 2010 to 2021. The search terms were a combination of medical subject headings terms and the subsequent terms: gallstone; common bile duct (stone); choledocholithiasis; cholecystitis; endoscopic retrograde cholangiography/ERCP; common bile duct exploration; intraoperative, preoperative, perioperative, and postoperative endoscopic retrograde cholangiography: stone extraction; and one-stage and two-stage procedure. Studies that compared two procedures or more were included, whereas studies not recording complications (bile leak, hemorrhage, pancreatitis, perforation, intra-abdominal infections, and other infections) or LOS were excluded. A network meta-analysis was conducted to compare the four different approaches for managing CBD stones.RESULTS: A total of 16 studies (8,644 participants) addressing the LOS and 41 studies (19,756 participants) addressing postprocedural complications were included in the analysis. The one-stage approaches were associated with a decrease in LOS compared with the two-stage approaches. Common bile duct exploration demonstrated a lower overall risk of complications compared with preoperative ERCP, but there were no differences in the overall risk orcomplications in the remaining comparisons. However, differences in specific postprocedural complications were detected between the four different approaches managing CBD stones.CONCLUSION: This network meta-analysis suggests that both laparoscopic CBD exploration and intraoperative ERCP have equally good outcomes and provide a preferable single-anesthesia patient pathway with a shorter overall length of hospital stay compared with the two-stage approaches.

- Background: The purpose of this study was to investigate the effect of preinjury β-blockade in patients experiencing isolated severe traumatic brain injury (TBI). We hypothesized that β-blockade before TBI is associated with improved survival.Methods: The trauma registry of an urban academic trauma center was queried to identify patients with an isolated severe TBI between January 2007 and December 2011. Isolated severe TBI was defined as an intracranial injury with an Abbreviated Injury Scale (AIS) score of 3 or greater excluding all extracranial injuries AIS score of 3 or greater. Patient demographics, clinical characteristics on admission, injury profile, Injury Severity Score (ISS), AIS score, in-hospital morbidity, and β-blocker exposure were abstracted for analysis. The primary outcome evaluated was in-hospital mortality stratified by preinjury β-blockade exposure.Results: Overall, a total of 662 patients met the study criteria. Of these, 25% (n = 159) were exposed to β-blockade before their traumatic insult. When comparing the demographics and injury characteristics between the groups, the sole difference was age, with the β-blocked group being older (69 [12] years vs. 63 [13] years, p < 0.001). β-blocked patients had a higher rate of infectious complications (30% vs. 19%, p = 0.04), with no difference in cardiac or pulmonary complications between the cohorts. Patients exposed to β-blockade versus no β-blockade experienced 13% and 22% mortality, respectively (p = 0.01). Stepwise logistic regression predicted the absence of β-blockade exposure as a risk factor for mortality (odds ratio, 2.7; 95% confidence interval, 1.5-4.8; p = 0.002). After adjustment for significant differences between the groups, patients not exposed to β-blockade experienced twofold increased risk of mortality (adjusted odds ratio, 2.2; 95% confidence interval, 1.3-3.7; p = 0.004).Conclusion: Preinjury β-blockade improves survival following isolated severe TBI. The role of prophylactic β-blockade and the timing of initiation of such therapy after TBI warrant further investigations.Level of evidence: Therapeutic study, level III; prognostic study, level II.

- BACKGROUND: The treatment of coagulopathy and bleeding in severe trauma requires rapid delivery of large amounts of plasma to emergency wards. The resulting need for adequate supplies of nonfrozen or thawed plasma has consequences for storage strategies. Using extensive population data from a setting where both fresh-frozen plasma (FFP) and cold-stored liquid plasma were used, this study investigates whether there is an association between short-term mortality after receipt of FFP or liquid plasma of different storage times. METHODS: A cohort of 84,986 Swedish patients was followed up from first recorded allogenic plasma transfusion for 14-day mortality. Associations with exposure to FFP were expressed as relative risks adjusted for patient characteristics, total transfusions, hospital, and calendar year. For non-FFP, the units given to patients who died and matched patients who survived were compared for their duration of storage. RESULTS: The relative risk of exposure to FFP was 1.19 (95% confidence interval: 1.12-1.27, p < 0.0001), with the risk elevation confined to the earlier calendar years of the study. There was no evidence of any effect of storage time of non-FFP. In analyses of all plasma types, FFP from male donors had lowest risk. CONCLUSIONS: Compared with exclusive use of never-frozen plasma, FFP was associated with increased short-term mortality in the era before leukocyte depletion. FFP from female donors had a significantly higher risk than male FFP. For non-FFP, duration of storage was unrelated to mortality. These findings can help to inform policies for managing high plasma demand in critical care.

- BACKGROUND: Systolic blood pressure (SBP) is a potential indicator that could guide when to use a resuscitative endovascular balloon occlusion of the aorta (REBOA) in trauma patients with life-threatening injuries. This study aims to determine the optimal SBP threshold for REBOA placement by analyzing the association between SBP pre-REBOA and 24-hour mortality in severely injured hemodynamically unstable trauma patients.METHODS: We performed a pooled analysis of the Aortic Balloon Occlusion (ABO) trauma and AORTA registries. These databases record the details related to the use of REBOA and include data from 14 countries worldwide. We included patients who had suffered penetrating and/or blunt trauma. Patients who arrived at the hospital with a SBP pre-REBOA of 0 mm Hg and remained at 0 mm Hg after balloon inflation were excluded. We evaluated the impact that SBP pre-REBOA had on the probability of death in the first 24 hours.RESULTS: A total of 1107 patients underwent endovascular aortic occlusion, of these, 848 met inclusion criteria. The median age was 44 years [IQR, 27-59 years] and 643(76%) were male. The median injury severity score was 34 [IQR, 25-45]. The median SBP pre-REBOA was 65 mm Hg [IQR: 49-88 mm Hg]. Mortality at 24-hours was reported in 279 (32%) patients. Math modelling shows that predicted probabilities of the primary outcome increased steadily in SBP pre-REBOA below 100 mm Hg. Multivariable mixed-effects analysis shows that when SBP pre-REBOA was lower than 60 mm Hg, the risk of death was more than 50% (relative risk, 1.5; 95%CI, 1.17-1.92; P = .001).DISCUSSION: In patients who do not respond to initial resuscitation, the use of REBOA in SBP's between 60- and 80-mm Hg may be a useful tool in resuscitation efforts before further decompensation or complete cardiovascular collapse. The findings from our study are clinically important as a first step in identifying candidates for REBOA.STUDY TYPE: Observational Study. LEVEL OF EVIDENCE: Level IV.

- Background: Health-related quality of life (HRQoL) is known to be significantly affected in former trauma patients. However, the underlying factors that lead to this outcome are largely unknown. In former intensive care unit (ICU) patients, it has been recognized that preexisting disease is the most important factor for the long-term HRQoL. The aim of this study was to investigate HRQoL up to 2 years after trauma and to examine the contribution of the trauma-specific, ICU-related, sociodemographic factors together with the effects of preexisting disease, and further to make a comparison with a large general population.Methods: A prospective 2-year multicenter study in Sweden of 108 injured patients. By mailed questionnaires, HRQoL was assessed at 6 months, 12 months, and 24 months after the stay in ICU by Short Form (SF)-36, and information of preexisting disease was collected from the national hospital database. ICU-related factors were obtained from the local ICU database. Comorbidity and HRQoL (SF-36) was also examined in the reference group, a random sample of 10,000 inhabitants in the uptake area of the hospitals.Results: For the trauma patients, there was a marked and early decrease in the physical dimensions of the SF-36 (role limitations due to physical problems and bodily pain). This decrease improved rapidly and was almost normalized after 24 months. In parallel, there were extensive decreases in the psychologic dimensions (vitality, social functioning, role limitations due to emotional problems, and mental health) of the SF-36 when comparisons were made with the general reference population.Conclusions: The new and important finding in this study is that the trauma population seems to have a trauma-specific HRQoL outcome pattern. First, there is a large and significant decrease in the physical dimensions of the SF-36, which is due to musculoskeletal effects and pain secondary to the trauma. This normalizes within 2 years, whereas the overall decrease in HRQoL remains and most importantly it is seen mainly in the psychologic dimensions and it is due to preexisting diseases

- BACKGROUND: Blood-based balanced resuscitation is a standard of care in massively bleeding trauma patients. No data exists as to when this therapy no longer significantly affects mortality. We sought to determine if there is a threshold beyond which further massive transfusion will not affect in-hospital mortality.METHODS: The Trauma Quality Improvement database was queried for all adult patients registered between 2013 and 2017 who received at least one unit of blood (PRBC) within 4 hours of arrival. In-hospital mortality was evaluated based on the total transfusion volume (TTV) at 4 and 24 hours in the overall cohort (OC) and in a balanced transfusion cohort (BC), composed of patients who received transfusion at a ratio of 1:1-2:1 PRBC-to-plasma. A bootstrapping method in combination with multivariable Poisson regression (MVR) was used to find a cutoff after which additional transfusion no longer affected in-hospital mortality. MVR was used to control for age, sex, race, highest abbreviated injury score in each body region, comorbidities, advanced directives limiting care, and the primary surgery performed for hemorrhage control.RESULTS: The OC consisted of 99,042 patients of which 28,891 and 30,768 received a balanced transfusion during the first 4 and 24 hours, respectively. The mortality rate plateaued after a TTV of 40.5 units (95% CI, 40-41) in the OC at 4 hours and after a TTV of 52.8 units (95% CI, 52-53) at 24 hours following admission. In the BC, mortality plateaued at a TTV of 39 units (95% CI, 39-39) and 53 units (95% CI, 53-53) at 4- and 24-hours following admission, respectively.CONCLUSION: Transfusion thresholds exist beyond which ongoing transfusion is not associated with any clinically significant change in mortality. These TTVs can be used as markers for resuscitation timeouts in order to assess the plan of care moving forward.LEVEL OF EVIDENCE: Level V, prognostic and epidemiological.

- BACKGROUND: Severe non-compressible torso hemorrhage (NCTH) remains a leading cause of potentially preventable death in modern military conflicts. Resuscitative endovascular occlusion of the aorta (REBOA) has demonstrated potential as an effective adjunct to the treatment of NCTH in the civilian early hospital and even pre-hospital settings - but the application of this technology for military pre-hospital use has not been well described. We aimed to assess the feasibility of both field and en route pre-hospital REBOA in the military exercise setting simulating a modern armed conflict.METHODS: Two adult male Sus Scrofa underwent simulated junctional combat injury in the context of a planned military training exercise. Both underwent zone I REBOA in conjunction with standard tactical combat casualty care (TCCC) interventions - one during point of injury care and the other during en route flight care. Animals were sequentially evacuated to two separate Forward Surgical Teams (FSTs) by rotary wing platform where the balloon position was confirmed by chest X-Ray. Animals then underwent different damage control thoracic and abdominal procedures before euthanasia.RESULTS: The first swine underwent immediate successful REBOA at the point of injury 7:30 minutes after the injury. It required 6 minutes total from initiation of procedure to effective aortic occlusion. Total occlusion time was 60 minutes. In the second animal, the REBOA placement procedure was initiated immediately after take-off (17:40 minutes after the injury). Although the movements and vibration of flight were not significant impediments, we only succeeded to put a 6-Fr sheath into a femoral artery during the 14 minutes flight due to lighting and visualization challenges. After the sheath had been upsized in the FST, the REBOA catheter was primarily placed in zone I followed by its replacement to zone III. Both animals survived to study completion and the termination of training. No complications were observed in either animal.CONCLUSION: Our study demonstrates the potential feasibility of REBOA for use during tactical field and en route (flight) care of combat casualties. Further study is needed to determine the optimal training and utilization protocols required to facilitate the effective incorporation of REBOA into military pre-hospital care capabilities.

- BACKGROUND: Hemorrhage from truncal and junctional injuries is responsible for the vast majority of potentially survivable deaths in combat casualties, causing most of its fatalities in the prehospital arena. Optimizing the deployment of the advanced bleeding control modalities required for the management of these injuries is essential to improve the survival of severely injured casualties. This study aimed to establish consensus on the optimal use and implementation of advanced bleeding control modalities in combat casualty care.METHODS: A Delphi method consisting of three rounds was used. An international expert panel of military physicians was selected by the researchers to complete the Delphi surveys. Consensus was reached if ≥70% of respondents agreed and if ≥70% responded.RESULTS: Thirty-two experts from 10 different nations commenced the process and reached consensus on which bleeding control modalities should be part of the standard equipment, that these modalities should be available at all levels of care, that only trained physicians should be allowed to apply invasive bleeding control modalities, but all medical and non-medical personnel should be allowed to apply non-invasive bleeding control modalities, and on the training requirements for providers. Consensus was also reached on the necessity of international registries and guidelines, and on certain indications and contraindications for resuscitative endovascular balloon occlusion of the aorta (REBOA) in military environments. No consensus was reached on the role of a wound clamp in military settings and the indications for REBOA in patients with chest trauma, penetrating axillary injury or penetrating neck injury in combination with thoraco-abdominal injuries.CONCLUSIONS: Consensus was reached on the contents of a standard bleeding control toolbox, where it should be available, providers and training requirements, international registries and guidelines, and potential indications for REBOA in military environments.

- BACKGROUND Vascular injuries in children are relatively uncommon. The objective of this population-based study was to investigate the epidemiology, management, and early outcomes of pediatric vascular injuries. METHODS A nationwide survey of prospectively collected data on pediatric vascular injuries in children 15 years or younger between 1987 and 2013 was conducted. Data were retrieved from the National Vascular Surgery registry (Swedvasc) and cross-matched with the National Population Register for mortality data. Demographics, operative techniques, and outcomes were analyzed. RESULTS There were 222 children (boys, n = 148; girls, n = 74) included in this study, with a mean (SD) age of 9.6 (4.1) years (range, 0.5-15 years; <6 years, 18 %; 6-10 years, 39%; >10 years, 42%). Blunt trauma mechanism (n = 146, 66%) was dominant, followed by penetrating (n = 51, 23%) and iatrogenic trauma (n = 21, 9%). Anatomic locations of vascular injuries were primarily upper extremities (n = 134, 60%) and lower extremities (n = 65, 29%), followed by the abdomen (n = 16, 7.2%). Upper extremity injuries were most common in the age group of 10 years or younger (78%, 100 of 128), and lower extremity injuries were most common in the age group of 11 years to 15 years (48%, 45 of 94). Major repair techniques included interposition graft (n = 54, 24%), patch (n = 43, 19%), primary repair (lateral suture/direct anastomosis) (n = 27, 12%), bypass (n = 21, 9.5%), and endovascular techniques (n = 8, 3.7%). Exploration or release of artery was performed in 51 cases (23%). Vein (n = 110) was the dominant graft material, and synthetic grafts (polytetrafluoroethylene/dacron) were only used in four open cases. The most common postoperative complication was arterial occlusion/thrombosis (n = 12). At 30-day follow-up, there was one above-knee and two below-knee amputations as well as one death. No more deaths at 1-year follow-up did occur. CONCLUSION This nationwide population-based study shows that traumatic vascular injuries in children are associated with high limb salvage rates and low mortality. Blunt trauma mechanism is dominant, and injuries are primarily located to the upper and lower extremities. The preferred repair techniques are venous patch angioplasty and interposition graft, and the frequency of endovascular repair is still low. LEVEL OF EVIDENCE Epidemiologic study, level III.

- BACKGROUND: Mortality from traumatic retrohepatic venous injuries is high and methods for temporary circulatory stabilization are needed. We investigated survival, and hemodynamic and metabolic effects of resuscitative endovascular balloon occlusion of the aorta (REBOA) and vena cava inferior (REBOVC) in anesthetized pigs.METHODS: Twenty-five anesthetized pigs in normovolemia or severe hemorrhagic shock (controlled arterial bleeding in blood bags targeting systolic arterial pressure of 50 mmHg, corresponding to 40-50% of the blood volume) were randomized to REBOA zone 1 or REBOA+REBOVC zone 1 (n=6-7/group) for 45 minutes occlusion, followed by 3-hour resuscitation and reperfusion. Hemodynamic and metabolic variables and markers of end-organ damage were measured regularly.RESULTS: During occlusion, both the REBOA groups had higher systemic mean arterial pressure (MAP) and cardiac output (P<0.05) compared to the two REBOA+REBOVC groups. After 60 minutes reperfusion, there were no statistically significant differences between the two REBOA groups and the two REBOA+REBOVC groups in MAP and cardiac output. The two REBOA+REBOVC groups had higher arterial lactate and potassium concentrations during reperfusion, compared to the two REBOA groups (P<0.05). There was no major difference in end-organ damage markers between REBOA and REBOA+REBOVC. Survival after one-hour reperfusion was 86% and 100% respectively in the normovolemic REBOA and REBOA+REBOVC groups, and 67% and 83% respectively in the corresponding hemorrhagic shock REBOA and REBOA+REBOVC groups.CONCLUSION: Acceptable hemodynamic stability during occlusion and short-term survival can be achieved by REBOA+REBOVC with adequate resuscitation; however, the more severe hemodynamic and metabolic impacts of REBOA+REBOVC compared to REBOA must be considered.LEVEL OF EVIDENCE: Prospective, randomized, experimental animal study. Basic science study, therapeutic.

- BACKGROUND: Resuscitative endovascular balloon occlusion of the vena cava inferior (REBOVC) may provide a minimal invasive alternative for hepatic vascular and inferior vena cava isolation in severe retrohepatic bleeding. However, circulatory stability may be compromised by the obstruction of venous return. The aim was to explore which combinations of arterial and venous endovascular balloon occlusions, and the Pringle maneuver, are hemodynamically possible in a normovolemic pig model. The hypothesis was that lower body venous blood pooling from REBOVC can be avoided by prior resuscitative endovascular aortic balloon occlusion (REBOA).METHODS: Nine anesthetized, ventilated, instrumented and normovolemic pigs were used to explore the hemodynamic effects of eleven combinations of REBOA and REBOVC, with or without the Pringle maneuver, in randomized order. The occlusions were performed for 5 minutes but interrupted if systolic blood pressure dropped below 40 mmHg. Hemodynamic variables were measured.RESULTS: Proximal REBOVC, isolated or in combination with other methods of occlusion, caused severely decreased systemic blood pressure and cardiac output, and had to be terminated before 5 min. The decreases in systemic blood pressure and cardiac output were avoided by REBOA at the same or a more proximal level. The Pringle maneuver had similar hemodynamic effects to proximal REBOVC.CONCLUSIONS: A combination of REBOA and REBOVC provides hemodynamic stability, in contrast to REBOVC alone or with the Pringle maneuver, and may be a possible adjunct in severe retrohepatic venous bleedings.Level of evidenceBasic science study, therapeutic.

- BACKGROUND: The aim of this experimental study was to compare survival and hemodynamic effects of a low-dose amiodarone and vasopressin compared with vasopressin in hypovolemic cardiac arrest model in piglets. METHODS: Eighteen anesthetized male piglets (with a weight of 25.3 [1.8] kg) were bled approximately 30% of the total blood volume via the femoral artery to a mean arterial blood pressure of 35 mm Hg in a 15-minute period. Afterward, the piglets were subjected to 4 minutes of untreated ventricular fibrillation followed by 11 minutes of open-chest cardiopulmonary resuscitation. At 5 minutes, circulatory arrest amiodarone 1 mg/kg was intravenously administered in the amiodarone group (n = 9), while the control group received the same amount of saline (n = 9). At the same time, all piglets received vasopressin 0.4 U/kg intravenously administered and hypertonic-hyperoncotic solution 3-mL/kg infusion for 20 minutes. Internal defibrillation was attempted from 7 minutes of cardiac arrest to achieve restoration of spontaneous circulation. The experiment was terminated 3 hours after resuscitation. RESULTS: Three-hour survival was greater in the amiodarone group (p = 0.02). After the successful resuscitation, the amiodarone group piglets had significantly lower heart rate as well as greater systolic, diastolic, and mean arterial pressure. Troponin I plasma concentrations were lower and urine output was greater in the amiodarone group. CONCLUSION: Combined resuscitation with amiodarone and vasopressin after hemorrhagic circulatory arrest resulted in greater 3-hour survival, better preserved hemodynamic parameters, and smaller myocardial injury compared with resuscitation with vasopressin only.

- Outcomes after surgical stabilization of rib fractures (SSRF) have not been studied in patients with multiple rib fractures and traumatic brain injury (TBI). We hypothesized that SSRF, as compared to nonoperative management, is associated with favorable outcomes in patients with TBI.A multicenter, retrospective cohort study was performed in patients with rib fractures and TBI between January 2012 and July 2019. Patients who underwent SSRF were compared to those managed nonoperatively. The primary outcome was mechanical ventilation-free days. Secondary outcomes were Intensive Care Unit (ICU-LOS) and hospital length of stay (HLOS), tracheostomy, occurrence of complications, neurologic outcome, and mortality. Patients were further stratified into moderate (GCS 9-12) and severe (GCS ≤8) TBI.The study cohort consisted of 456 patients of which 111 (24.3%) underwent SSRF. SSRF was performed at a median of 3 days and SSRF-related complication rate was 3.6%. In multivariable analyses, there was no difference in mechanical ventilation-free days between the SSRF and nonoperative groups. The odds of developing pneumonia (OR 0.59 (95% CI 0.38-0.98), p=0.043) and 30-day mortality (OR 0.32 (95% CI 0.11-0.91), p=0.032) were significantly lower in the SSRF group. Patients with moderate TBI had similar outcome in both groups. In patients with severe TBI, the odds of 30-day mortality was significantly lower after SSRF (0.19 (95% CI 0.04-0.88), p=0.034).In patients with multiple rib fractures and TBI, the mechanical ventilation-free days did not differ between the two treatment groups. In addition, SSRF was associated with a significantly lower risk of pneumonia and 30-day mortality. In patients with moderate TBI, outcome was similar. In patients with severe TBI a lower 30-day mortality was observed. There was a low SSRF-related complication risk. These data suggest a potential role for SSRF in select patients with TBI.Therapeutic, level IV.

- The presence of six or more rib fractures or a displaced rib fracture due to cardiopulmonary resuscitation (CPR) has been associated with longer hospital and intensive care unit (ICU) length of stay (LOS). Evidence on the effect of surgical stabilization of rib fractures (SSRF) following CPR is limited. This study aimed to evaluate outcomes after SSRF versus nonoperative management in patients with multiple rib fractures after CPR.An international, retrospective study was performed in patients who underwent SSRF or nonoperative management for multiple rib fractures following CPR between January 1, 2012, and July 31, 2020. Patients who underwent SSRF were matched to nonoperative controls by cardiac arrest location and cause, rib fracture pattern, and age. The primary outcome was ICU LOS.Thirty-nine operatively treated patient were matched to 66 nonoperatively managed controls with comparable CPR-related characteristics. Patients who underwent SSRF more often had displaced rib fractures (n = 28 [72%] vs. n = 31 [47%]; p = 0.015) and a higher median number of displaced ribs (2 [P 25 -P 75 , 0-3] vs. 0 [P 25 -P 75 , 0-3]; p = 0.014). Surgical stabilization of rib fractures was performed at a median of 5 days (P 25 -P 75 , 3-8 days) after CPR. In the nonoperative group, a rib fixation specialist was consulted in 14 patients (21%). The ICU LOS was longer in the SSRF group (13 days [P 25 -P 75 , 9-23 days] vs. 9 days [P 25 -P 75 , 5-15 days]; p = 0.004). Mechanical ventilator-free days, hospital LOS, thoracic complications, and mortality were similar.Despite matching, those who underwent SSRF over nonoperative management for multiple rib fractures following CPR had more severe consequential chest wall injury and a longer ICU LOS. A benefit of SSRF on in-hospital outcomes could not be demonstrated. A low consultation rate for rib fixation in the nonoperative group indicates that the consideration to perform SSRF in this population might be associated with other nonradiographic or injury-related variables.Therapeutic/Care Management; Level III.
