AbstractThis study was aimed at a serial evaluation of the prognostic values of initial shockable rhythm, bystander cardiopulmonary resuscitation (CPR) and gender for neurological outcome and survival in adults treated with targeted temperature management (TTM) following cardiac arrest (CA). PubMed, Embase and the Cochrane Library were searched for eligible studies. Pooled odds ratio (OR) with 95% confidence intervals (CIs) was calculated to evaluate prognostic values using RevMan 5.3. The outcomes were favorable neurological outcome (defined as cerebral performance category of 1 and 2) and survival. Seventeen studies were subjected to the meta-analysis. Favorable neurological outcome was associated with significantly higher odds of an initial shockable rhythm (OR: 7.63, 95%CI: 6.51-8.96), bystander CPR (OR: 1.44, 95%CI: 1.14-1.82), male (OR: 1.39, 95%CI: 1.20-1.61). Survival was associated with higher odds of an initial shockable rhythm (OR: 4.88, 95%CI: 3.18-4.79), higher odds of bystander CPR (OR: 1.71, 95%CI: 1.05-2.77). No significant association was found between survival and male. In adult patients treated with TTM, initial shockable rhythm, bystander CPR and male sex were associated with a higher likelihood of favorable neurological outcome. Initial shockable rhythm and bystander CPR were associated with a higher likelihood of survival. These factors could help in identifying patients who are eligible for TTM.Copyright © 2018.
