- BackgroundStudies have addressed the effect of multimodal pain rehabilitation (MMR), whereas criteria for selection are sparse. This study examines whether higher scores on musculoskeletal pain measures are associated with selection to MMR, and whether this differs across gender. MethodA clinical population of 262 male and 589 female patients was recruited consecutively during 3 years, 2007-2010. The patients were referred from primary care to a pain rehabilitation clinic in Northern Sweden for assessment and selection to MMR. Register-based data on self-reported pain were linked to patients' records where outcome (MMR or not) was stated. We modelled odds ratios for selection to MMR by higher scores on validated pain measures (pain severity, interference with daily life, pain sites and localized pain vs. varying pain location). Covariates were age, educational level and multiple pain measures. Anxiety and depression (Hospital, Anxiety and Depression Scale) and working status were used in sensitivity tests. ResultsHigher scores of self-reported pain were not associated with selection to MMR in multivariate models. Among women, higher scores on pain severity, pain sites and varying pain location (localized pain=reference) were negatively associated with selection to MMR. After adjustment for multiple pain measures, the negative odds ratio for varying location persisted (OR=0.59, 95% CI=0.39-0.89). ConclusionHigher scores on self-reported pain did not guide selection to MMR and a negative trend was found among women. Studies of referral patterns and decision processes may contribute to a better understanding of the clinical practice that decides selection to MMR.

- BACKGROUND: Breathing exercises with positive expiratory pressure (PEP) are used to improve pulmonary function and airway clearance. Different PEP devices are available, but there have been no studies that describe the pressure generated by different resistors. The purpose of this study was to compare pressures generated from the proprietary resistor components of 4 commercial flow-dependent PEP valves with all other parameters kept constant. METHODS: Resistors from 4 flow-regulated PEP devices (Pep/Rmt system, Wellspect HealthCare; Pipe P breathing exerciser, Koo Medical Equipment; Mini-PEP, Philips Respironics [including resistors by Rusch]; and 15-mm endo-adapter, VBM Medizintechnik) were tested randomly by a blinded tester at constant flows of 10 and 18 L/min from an external gas system. All resistors were tested 3 times. RESULTS: Resistors with a similar diameter produced statistically significant different pressures at the same flow. The differences were smaller when the flow was 10 L/min compared with 18 L/min. The differences were also smaller when the diameter of the resistor was increased. The pressures produced by the 4 resistors of the same size were all significantly different when measuring 1.5- and 2.0-mm resistors at a flow of 10 L/min and 2.0-mm resistors at a flow of 18 L/min (P < .001). There were no significant differences between any of the resistors when testing sizes of 4.5 and 5.0 mm at either flow. The Mini-PEP and adapter resistors gave the highest pressures. CONCLUSIONS: Pressures generated by the different proprietary resistor components of 4 commercial PEP devices were not comparable, even though the diameter of the resistors is reported to be the same. The pressures generated were significantly different, particularly when using small-diameter resistors at a high flow. Therefore, the resistors may not be interchangeable. This is important information for clinicians, particularly when considering PEP for patients who do not tolerate higher pressures. (C) 2015 Daedalus Enterprises

- Aim of the study: To document the acute magnetic resonance imaging (MRI) findings on the brain in cardiac arrest (CA) patients treated with therapeutic hypothermia (TH) and their relation to patients’ neurological outcome after 6 months.Method: A prospective observational study with MRI was performed regardless the level of consciousness in 56 post-CA patients treated with TH.Results: MRI of the brain was obtained at a median of 4 days (3-13 days). At 6 months, 32/56 had survived with good neurological outcome. The MMSE was performed in 28/32 (88%) patients with a median of 28 (24-30). Acute ischemic lesions were found on diffusion-weighted MRI (DWI) in 34 (61%) patients and were more common in patients with poor outcome (p=0.006). Acute ischemic injuries affected mostly gray matter, deep or cortical and with or without involvement of the underlying white matter. Very few lesions were pure white matter lesions. Lesions in the occipital and temporal lobes, deep gray matter and cerebellum were most associated with poor outcome. Reductions in the apparent diffusion coefficient (ADC) were more common in patients with poor outcome, particularly in the occipital lobes. None of the patients with an ADC below 600x10-6 mm2/s in any region survived to 6 months.Conclusions: In visual analyses of acute MRI, extensive acute lesions were found in the cortical regions and gray matter and were associated with poor outcome. In ADC measurements, low values were associated with poor outcome. Patients with good outcome showed a minor pathological pattern mainly in the frontal and parietal lobes.

Novel Interventions in Cardiac Arrest : Targeted Temperature Management, Methylene Blue, S-PBN, Amiodarone, Milrinone and Esmolol, Endothelin and Nitric Oxide In Porcine Resuscitation Models
- 2015

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- It is a major clinical problem that survival rates after out-of-hospital cardiac arrest have not markedly improved during the last decades, despite extensive research and the introduction of new interventions. However, recent studies have demonstrated promising treatments such as targeted temperature management (TTM) and methylene blue (MB).In our first study, we investigated the effect of MB administered during experi-mental cardiopulmonary resuscitation (CPR) in the setting of postponed hypother-mia in piglets. We set out to study if MB could compensate for a delay to establish targeted TTM. The study demonstrated that MB more than compensated for 30 min delay in induction of TTM. The effect of MB added to that of TTM.The second study examined the effects of TTM and S-PBN on the endothelin system and nitric oxide synthases (NOS) after prolonged CA in a porcine CPR mod-el. The study was designed to understand the cardioprotective mechanism of S-PBN and TTM by their influence on the endothelin system and NOS regulation. We veri-fied for the first time, that these two cardioprotective postresuscitative interventions activate endothelin-1 and its receptors concomitantly with eNOS and nNOS in the myocardium. We concluded that nitric oxide and endothelin pathways are implicated in the postresuscitative cardioprotective effects of TTM.The third study compared survival and hemodynamic effects of low-dose amio-darone and vasopressin to vasopressin in a porcine hypovolemic CA model. The study was designed to evaluate whether resuscitation with amiodarone and vasopressin compared to vasopressin alone would have an impact on resuscitation success, survival, and hemodynamic parameters after hemorrhagic CA. We found that 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 to resuscitation with vasopressin only.In our fourth study we planned to compare hemodynamic parameters between the treatment group (milrinone, esmolol and vasopressin; MEV) and control group (vasopressin only) during resuscitation from prolonged cardiac arrest in piglets. The study was designed to demonstrate if MEV treatment improved hemodynamics or cardiac damage compared to controls. We demonstrated that MEV treatment reduced cardiac injury compared with vasopressin alone.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- In the prehospital setting, a point-of-care diagnostic test is needed to diagnose pneumothorax (PTX) and monitor its progression to prevent unnecessary patient morbidity and mortality. Ultrasonography is more sensitive than supine chest x-ray for diagnosing PTX, but the accuracy depends on the experience of the operator. Therefore, a non-operator dependent instrument would be valuable for detection and continuous monitoring of an evolving PTX.

- Background: In a holistic view of care, the family is important for the patient as well as for the staff and integration of family members in health care is a growing trend. Yet, family participation in the care is sparsely investigated and valid assessment instruments are needed. Setting: Data were collected from 200 family members participating in an intervention study at an emergency department (ED) in Sweden. Method: The Person-centred Climate Questionnaire Family (PCQ-F) is a measure for how family members perceive the psychosocial climate. PCQ-F is a self-report instrument that contains 17 items assessing safety, every-dayness and hospitality - three subscale dimensions that mirror the Swedish patient version of the questionnaire, the PCQ-P. Aim: The aim of this study was to evaluate the psychometric properties of the Swedish version of the PCQ-F in an ED context. Results: The psychometric properties of the PCQ-F were evaluated using statistical estimates of validity and reliability and showed high content validity and internal consistency. Cronbach's Alpha was >0.7 and item-total correlations were >0.3 and <0.7. Conclusion: In terms of psychometrics, the findings in this study indicate that the PCQ-F can be used with satisfactory validity and reliability to explore to what degree family members perceive ED settings as being person-centred, safe, welcoming and hospitable within an everyday and decorated physical environment. As the PCQ already exists in a valid and reliable patient (PCQ-P) and staff (PCQ-S) version, this new family member version is a significant addition to the literature as it enables further comparative studies of how diverse care settings are perceived by different stakeholders.

Chromogranin A and cortisol at intraoperative repeated noxious stimuli : surgical stress in a dog model
- 2015
-
Ingår i: SAGE Open Medicine. - : SAGE Publications. - 2050-3121. ; 3
-
Tidskriftsartikel (refereegranskat)abstract
- Objectives: Biomarkers representing sympathetic tone and the surgical stress response are measured to objectively evaluate surgical techniques and anaesthetic protocols. If a part of the intraoperative procedure is repeated on the contralateral organ, one animal may potentially serve as its own control and, if so, may minimize the problem of individual differences of the stress response to anaesthesia and surgery. This study aimed to investigate the use of chromogranin A for measurement of the intraoperative sympathetic tone. Additional aims were to investigate chromogranin A and cortisol as indicators of the intraoperative surgical stress response caused by repeated noxious stimuli in dogs subjected to ovariohysterectomy and thereby to investigate the possibility of one dog serving as its own control. Methods: Experiments were carried out on 10 dogs subjected to ovariohysterectomy. Perioperative blood samples (0-6) were collected after premedication, immediately before induction of anaesthesia (0), after induction of anaesthesia and before incision (1), before (2) and after (3) removal of the first ovary, after a 15-min pause before removal of the second ovary (4), after removal of the second ovary (5) and after closing the abdomen (6). Plasma chromogranin A and cortisol were analysed. Results: Plasma chromogranin A did not change. Plasma cortisol concentration did not change between before anaesthesia and opening of the abdomen. Plasma cortisol increased at removal of the first ovary. Cortisol did not change at removal of the second ovary but remained increased compared to initial sample. Conclusion: The results suggest chromogranin A is a poor indicator of intraoperative sympathetic tone during elective surgery in dogs. Cortisol measurement was useful for assessment of intraoperative noxious stimuli. However, at these test conditions, neither plasma chromogranin A nor plasma cortisol was useful for assessment of repeated intraoperative noxious stimuli where one dog served as its own control..

Tidskriftsartikel (refereegranskat)abstract
- Objectives: The aim of this study was to compare the effect on self-rated pain, disability, and self-efficacy of 3 interventions for the management of chronic whiplash-associated disorders: physiotherapist-led neck-specific exercise (NSE), physiotherapist-led NSE with the addition of a behavioral approach, or Prescription of Physical Activity (PPA). Materials and Methods: A total of 216 volunteers with chronic whiplash-associated disorders participated in this randomized, assessor blinded, clinical trial of 3 exercise interventions. Self-rated pain/pain bothersomeness (Visual Analogue Scale), disability (Neck Disability Index), and self-efficacy (Self-Efficacy Scale) were evaluated at baseline and at 3 and 6 months. Results: The proportion of patients reaching substantial reduction in pain bothersomness (at least 50% reduction) was more evident (P less than 0.01) in the 2 NSE groups (29% to 48%) compared with the PPA group (5%) at 3 months. At 6 months 39% to 44% of the patients in the 2 neck-specific groups and 28% in the PPA group reported substantial pain reduction. Reduction of disability was also larger in the 2 neck-specific exercise groups at both 3 and 6 months (P less than 0.02). Self-efficacy was only improved in the NSE group without a behavioral approach (P = 0.02). However, there were no significant differences in any outcomes between the 2 physiotherapist-led NSE groups. Discussion: NSE resulted in superior outcomes compared with PPA in this study, but the observed benefits of adding a behavioral approach to the implementation of exercise in this study were inconclusive.

Percutaneously inserted long-term central venous catheters in pigs of different sizes

- Pigs are used for long-term biomedical experiments requiring repeated injections, infusions and collections of blood samples. Thus, it is necessary for vascular catheters to be indwelling to avoid undue stress to the animals and the use of restraints. We propose a refined model of percutaneous insertion of long-term central venous catheters to minimize the surgical trauma and postoperative complications associated with catheter insertion. Different sizes of needles (18 Ga versus 21 Ga) for initial puncture of the veins were compared. In conventional pigs weighing less than 30 kg, catheter insertion may be facilitated by using a microintroducer set with a 21 Ga needle. In pigs weighing 50 kg, a standard 18 Ga needle may be preferable.
