- Aims: Mechanical ventilation practices in patients with cardiac arrest are not well described. Also, the effect of temperature on mechanical ventilation settings is not known. The aims of this study were 1) to describe practice of mechanical ventilation and its relation with outcome 2) to determine effects of different target temperatures strategies (33 °C versus 36 °C) on mechanical ventilation settings. Methods: This is a substudy of the TTM-trial in which unconscious survivors of a cardiac arrest due to a cardiac cause were randomized to two TTM strategies, 33 °C (TTM33) and 36 °C (TTM36). Mechanical ventilation data were obtained at three time points: 1) before TTM; 2) at the end of TTM (before rewarming) and 3) after rewarming. Logistic regression was used to determine an association between mechanical ventilation variables and outcome. Repeated-measures mixed modelling was performed to determine the effect of TTM on ventilation settings. Results: Mechanical ventilation data was available for 567 of the 950 TTM patients. Of these, 81% was male with a mean (SD) age of 64 (12) years. At the end of TTM median tidal volume was 7.7 ml/kg predicted body weight (PBW)(6.4–8.7) and 60% of patients were ventilated with a tidal volume ≤ 8 ml/kg PBW. Median PEEP was 7.7cmH2O (6.4–8.7) and mean driving pressure was 14.6 cmH2O (±4.3). The median FiO2 fraction was 0.35 (0.30–0.45). Multivariate analysis showed an independent relationship between increased respiratory rate and 28-day mortality. TTM33 resulted in lower end-tidal CO2 (Pgroup = 0.0003) and higher alveolar dead space fraction (Pgroup = 0.003) compared to TTM36, while PCO2 levels and respiratory minute volume were similar between groups. Conclusions: In the majority of the cardiac arrest patients, protective ventilation settings are applied, including low tidal volumes and driving pressures. High respiratory rate was associated with mortality. TTM33 results in lower end-tidal CO2 levels and a higher alveolar dead space fraction compared to TTTM36.

- There is a need for large trials that test the clinical effectiveness of interventions in the field of perioperative medicine. Clinical outcome measures used in such trials must be robust, clearly defined and patient-relevant. Our objective was to develop standards for the use of clinical outcome measures to strengthen the methodological quality of perioperative medicine research. A literature search was conducted using PubMed and opinion leaders worldwide were invited to nominate papers that they believed the group should consider. The full texts of relevant articles were reviewed by the taskforce members and then discussed to reach a consensus on the required standards. The report was then circulated to opinion leaders for comment and review. This report describes definitions for 22 individual adverse events with a system of severity grading for each. In addition, four composite outcome measures were identified, which were designed to evaluate postoperative outcomes. The group also agreed on standards for four outcome measures for the evaluation of healthcare resource use and quality of life. Guidance for use of these outcome measures is provided, with particular emphasis on appropriate duration of follow-up. This report provides clearly defined and patient-relevant outcome measures for large clinical trials in perioperative medicine. These outcome measures may also be of use in clinical audit. This report is intended to complement and not replace other related work to improve assessment of clinical outcomes following specific surgical procedures.

- To describe the prevalence of, risk factors for, and prognostic importance of gastrointestinal (GI) bleeding and use of acid suppressants in acutely ill adult intensive care patients. We included adults without GI bleeding who were acutely admitted to the intensive care unit (ICU) during a 7-day period. The primary outcome was clinically important GI bleeding in ICU, and the analyses included estimations of baseline risk factors and potential associations with 90-day mortality. A total of 1,034 patients in 97 ICUs in 11 countries were included. Clinically important GI bleeding occurred in 2.6 % (95 % confidence interval 1.6-3.6 %) of patients. The following variables at ICU admission were independently associated with clinically important GI bleeding: three or more co-existing diseases (odds ratio 8.9, 2.7-28.8), co-existing liver disease (7.6, 3.3-17.6), use of renal replacement therapy (6.9, 2.7-17.5), co-existing coagulopathy (5.2, 2.3-11.8), acute coagulopathy (4.2, 1.7-10.2), use of acid suppressants (3.6, 1.3-10.2) and higher organ failure score (1.4, 1.2-1.5). In ICU, 73 % (71-76 %) of patients received acid suppressants; most received proton pump inhibitors. In patients with clinically important GI bleeding, crude and adjusted odds for mortality were 3.7 (1.7-8.0) and 1.7 (0.7-4.3), respectively. In ICU patients clinically important GI bleeding is rare, and acid suppressants are frequently used. Co-existing diseases, liver failure, coagulopathy and organ failures are the main risk factors for GI bleeding. Clinically important GI bleeding was not associated with increased adjusted 90-day mortality, which largely can be explained by severity of comorbidity, other organ failures and age.

- Background: The aim of this study was to describe out-of-hospital cardiac arrest (OHCA) survivors' ability to participate in activities of everyday life and society, including return to work. The specific aim was to evaluate potential effects of cognitive impairment. Methods and Results: Two hundred eighty-seven OHCA survivors included in the TTM trial (Target Temperature Management) and 119 matched control patients with ST-segment-elevation myocardial infarction participated in a follow-up 180 days post-event that included assessments of participation, return to work, emotional problems, and cognitive impairment. On the Mayo-Portland Adaptability Inventory-4 Participation Index, OHCA survivors (n=270) reported more restricted participation In everyday life and in society (47% versus 30%; P<0.001) compared with ST-segment-elevation myocardial infarction controls (n=118). Furthermore, 27% (n=36) of pre-event working OHCA survivors (n=135) compared with 7% (n=3) of pre-event working ST-segment-elevation myocardial infarction controls (n=45) were on sick leave (odds ratio, 4.9; 95% confidence interval, 1.4-16.8; P=0.01). Among the OHCA survivors assumed to return to work (n=135), those with cognitive impairment (n=55) were 3× more likely (odds ratio, 3.3; 95% confidence interval, 1.2-9.3; P=0.02) to be on sick leave compared with those without cognitive impairment (n=40; 36%, n=20, versus 15%, n=6). For OHCA survivors, the variables that were found most predictive for a lower participation were depression, restricted mobility, memory impairment, novel problem-solving difficulties, fatigue, and slower processing speed. Conclusions: OHCA survivors reported a more restricted societal participation 6 months post-arrest, and their return to work was lower compared with ST-segment-elevation myocardial infarction controls. Cognitive impairment was significantly associated with lower participation, together with the closely related symptoms of fatigue, depression, and restricted mobility. These predictive variables may be used during follow-up to identify OHCA survivors at risk of a less successful recovery that may benefit from further support and rehabilitation.
