Review Meta Analysis
Predictors of poor neurological outcome in adult comatose survivors of cardiac arrest: A systematic review and meta-analysis. Part 1: Patients not treated with therapeutic hypothermia.
To systematically review the accuracy of early (≤7 days) predictors of poor outcome defined as death or vegetative state (Cerebral Performance Categories [CPC] 4-5) or death, vegetative state or severe disability (CPC 3-5) in comatose survivors from cardiac arrest not treated using therapeutic hypothermia (TH). PubMed, Scopus and the Cochrane Database of Systematic reviews were searched for eligible studies. Sensitivity, specificity, false positive rates (FPR) for each predictor were calculated and results of predictors with similar time points and outcome definitions were pooled. Quality of evidence (QOE) was evaluated according to the GRADE guidelines. ⋯ In comatose resuscitated patients not treated with TH presence of myoclonus, absence of pupillary reflex, bilateral absence of N20 SSEP wave and low EEG voltage each predicted poor outcome early and accurately, but with a relevant risk of bias.

Review Meta Analysis
Predictors of poor neurological outcome in adult comatose survivors of cardiac arrest: A systematic review and meta-analysis. Part 2: Patients treated with therapeutic hypothermia.
To systematically review the accuracy of early (≤7 days) predictors of poor outcome, defined as death or vegetative state (Cerebral Performance Categories [CPC] 4-5) or death, vegetative state or severe disability (CPC 3-5), in comatose adult survivors from cardiac arrest (CA) treated using therapeutic hypothermia (TH). Electronic databases were searched for eligible studies. Sensitivity, specificity, and false positive rates (FPR) for each predictor were calculated. Quality of evidence (QOE) was evaluated according to the GRADE guidelines. ⋯ in the first 7 days after CA, a bilaterally absent N20 SSEP wave anytime, a nonreactive EEG after rewarming or a combination of absent ocular reflexes and M≤2 after rewarming predicted CPC 3-5 with 0% FPR and narrow 95% CIs, but with a high risk of bias.

Following successful resuscitation from cardiac arrest, a prothrombotic state may contribute to end-organ dysfunction. We examined whether the level of serum thrombin-antithrombin (TAT) in patients hospitalized after cardiac arrest was associated with survival or the development of multiple organ failure (MOF). ⋯ Initial serum TAT levels and category of illness severity are associated with survival. TAT levels are not associated with development of MOF. Initial TAT levels may be a useful prognostic adjunct in the post arrest population.

Comparative Study Observational Study
Combining brain computed tomography and serum neuron specific enolase improves the prognostic performance compared to either alone in comatose cardiac arrest survivors treated with therapeutic hypothermia.
We determined whether combining the grey-to-white matter ratio (GWR) on brain computed tomography (CT) and serum neuron specific enolase (NSE) improves the prognostic performance when compared to either alone in cardiac arrest patients treated with therapeutic hypothermia (TH). ⋯ Combining brain CT and serum NSE improves the prognostic performance when compared to either alone in predicting poor neurologic outcome in cardiac arrest patients treated with TH.
