- IMPORTANCE Brain injury affects neurologic function and quality of life in survivors after cardiac arrest. OBJECTIVE To compare the effects of 2 target temperature regimens on long-term cognitive function and quality of life after cardiac arrest. DESIGN, SETTING, AND PARTICIPANTS In this multicenter, international, parallel group, assessor-masked randomized clinical trial performed from November 11, 2010, through January 10, 2013, we enrolled 950 unconscious adults with cardiac arrest of presumed cardiac cause from 36 intensive care units in Europe and Australia. Eleven patients were excluded from analysis for a total sample size of 939. INTERVENTIONS Targeted temperature management at 33 degrees C vs 36 degrees C. MAIN OUTCOMES AND MEASURES Cognitive function was measured by the Mini-Mental State Examination (MMSE) and assessed by observers through the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE). Patients reported their activities in daily life and mental recovery through Two Simple Questions and their quality of life through the Medical Outcomes Study 36-Item Short Form Health Survey, version 2. RESULTS In the modified intent-to-treat population, including nonsurvivors, the median MMSE score was 14 in the 33 degrees C group (interquartile range [IQR], 0-28) vs 17 in the 36 degrees C group (IQR, 0-29) (P = .77), and the IQCODE score was 115 (IQR, 79-130) vs 115 (IQR, 80-130) (P = .57) in the 33 degrees C and 36 degrees C groups, respectively. The median MMSE score for survivors was within the reference range and similar (33 degrees C group median, 28; IQR, 26-30; vs 36 degrees C group median, 28; IQR, 25-30; P = .61). The median IQCODE score was within the minor deficit range (33 degrees C group median, 79.5; IQR, 78.0-85.9; vs 36 degrees C group median, 80.7; IQR, 78.0-86.9; P = .04). A total of 18.8% vs 17.5% of survivors reported needing help with everyday activities (P = .71), and 66.5% in the 33 degrees C group vs 61.8% in the 36 degrees C group reported that they thought they had made a complete mental recovery (P = .32). The mean (SD) mental component summary score was 49.1 (12.5) vs 49.0 (12.2) (P = .79), and the mean (SD) physical component summary score was 46.8 (13.8) and 47.5 (13.8) (P = .45), comparable to the population norm. CONCLUSIONS AND RELEVANCE Quality of life was good and similar in patients with cardiac arrest receiving targeted temperature management at 33 degrees C or 36 degrees C. Cognitive function was similar in both intervention groups, but many patients and observers reported impairment not detected previously by standard outcome scales.

- -Target temperature management is recommended as a neuro-protective strategy after out-of-hospital cardiac arrest. Potential effects of different target temperatures on cognitive impairment commonly described in survivors are not sufficiently investigated. The primary aim of this study was to evaluate whether a target temperature of 33ºC compared to 36ºC was favourable for cognitive function, and secondary to describe cognitive impairment in cardiac arrest survivors in general.

- Introduction: Prophylactic antibiotics (PRO) reduce the incidence of early-onset pneumonia in comatose patients with structural brain injury, but have not been examined in cardiac arrest survivors undergoing targeted temperature management (TTM). We investigated the effect of PRO on the development of pneumonia in that population. Methods: We conducted a retrospective cohort study comparing patients treated with PRO to those not receiving PRO (no-PRO) using Northern Hypothermia Network registry data. Cardiac arrest survivors >= 18 years of age with a GCS < 8 at hospital admission and treated with TTM at 32-34 degrees C were enrolled in the registry. Differences were analyzed in univariate analyses and with logistic regression models to evaluate independent associations of clinical factors with incidence of pneumonia and good functional outcome. Results: 416 of 1240 patients (33.5%) received PRO. Groups were similar in age, gender, arrest location, initial rhythm, and time from collapse to return of spontaneous circulation. PRO patients had less pneumonia (12.6% vs. 54.9%, p < 0.001) and less sepsis (1.2 vs. 5.7%, p < 0.001) compared to no-PRO patients. ICU length of stay (98 vs. 100 h, p = 0.2) and incidence of a good functional outcome (41.1 vs. 36.6%, p = 0.19) were similar between groups. Backwards stepwise logistic regression demonstrated PRO were independently associated with a lower incidence of pneumonia (OR 0.09, 95% 0.06-0.14, p < 0.001) and a similar incidence of good functional outcome. Conclusions: Prophylactic antibiotics were associated with a reduced incidence of pneumonia but a similar rate of good functional outcome.
