- Targeted temperature management (TTM) of 32-34 °C has been the standard treatment for out-of-hospital cardiac arrest since clinical trials in 2002 showed benefits to survival and neurological outcome. Recently, this treatment has been challenged by another clinical trial showing no difference in outcome between TTM of 33 °C and 36 °C. This protocol describes the methodology for a meta-analysis detailing temperature-reducing interventions to treat global ischaemia in animal models. By combining relevant data sets in the literature, we will explore the experimental evidence for TTM. Our aims are to explain possible translational gaps and provide methodological considerations for future experimental research and clinical trials.

- 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 3x 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.

- Introduction: Routine EEG is widely used and accessible for post arrest neuroprognostication. Recent studies, using standardised EEG terminology, have proposed highly malignant EEG patterns with promising predictive ability. Objectives: To validate the performance of standardised routine EEG patterns to predict neurological outcome after cardiac arrest. Methods: In the prospective multicenter Target Temperature Management trial, comatose cardiac arrest patients were randomised to different temperature levels (950 patients, 36 sites). According to the prospective protocol a routine EEG was performed in patients who remained comatose after the 36 h temperature control intervention. EEGs were retrospectively reviewed blinded to outcome using the standardised American Clinical Neurophysiology Society terminology. Highly malignant, malignant and benign EEG patterns were correlated to poor and good outcome, defined by best achieved Cerebral Performance Category up to 180 days. Results: At 20 sites 207 patients had a routine EEG performed at median 76 h after cardiac arrest. Highly malignant patterns (suppression or burst-suppression with or without discharges) had a high specificity for poor outcome (98%, CI 92–100), but with limited sensitivity (31%, CI 24–39). Our false positive patient had a burst-suppression pattern during ongoing sedation. A benign EEG, i.e. continuous normal-voltage background without malignant features, identified patients with good outcome with 77% (CI 66–86) sensitivity and 80% (CI 73–86) specificity. Conclusion: Highly malignant routine EEG after targeted temperature management is a strong predictor of poor outcome. A benign EEG is an important indicator of a good outcome for patients remaining in coma.

- Background: Admission lactate and lactate clearance are implemented for risk stratification in sepsis and trauma. In out-of-hospital cardiac arrest, results regarding outcome and lactate are conflicting. Methods: This is a post-hoc analysis of the Target Temperature Management trial in which 950 unconscious patents after out-of-hospital cardiac arrest were randomized to a temperature intervention of 33°C or 36°C. Serial lactate samples during the first 36 hours were collected. Admission lactate, 12-hour lactate, and the clearance of lactate within 12 hours after admission were analyzed and the association with 30-day mortality assessed. Results: Samples from 877 patients were analyzed. In univariate logistic regression analysis, the odds ratio for death by day 30 for each mmol/L was 1.12 (1.08-1.16) for admission lactate, P <.01, 1.21 (1.12-1.31) for 12-hour lactate, P <.01, and 1.003 (1.00-1.01) for each percentage point increase in 12-hour lactate clearance, P =.03. Only admission lactate and 12-hour lactate levels remained significant after adjusting for known predictors of outcome. The area under the receiver operating characteristic curve was 0.65 (0.61-0.69), P <.001, 0.61 (0.57-0.65), P <.001, and 0.53 (0.49-0.57), P =.15 for admission lactate, 12-hour lactate, and 12-hour lactate clearance, respectively. Conclusions: Admission lactate and 12-hour lactate values were independently associated with 30-day mortality after out-of-hospital cardiac arrest while 12-hour lactate clearance was not. The clinical value of lactate as the sole predictor of outcome after out-of-hospital cardiac arrest is, however, limited.

- European Resuscitation Council (ERC) issued updated guidelines for postresuscitation care in 2015. This paper provides updated Swedish recommendations for neurological prognostication of patients remaining unconscious after cardiac arrest (CA). The prognostication should be based on independent methods; clinical and neurophysiological examinations, imaging and biomarkers. It should not be performed earlier than three days after CA and any influence from sedatives must be negligible. Bilateral absence of both corneal and pupillary reflexes and bilaterally absent Somatosensory Evoked N20 Potentials (SSEP) at 72 hours are reliable predictors of poor outcome but the ocular reflexes have limited sensitivity and SSEP has limited availability. Hence, further delay of at least 24 hours and combinations of findings from multiple methods are often needed for reliable prognostication. If firm evidence of a poor prognosis is lacking four days after CA, further expectation with repeated examinations is recommended. © 2017, Swedish Medical Association. All rights reserved.
