Background: Cardiac arrest carries high mortality and morbidity burden. Different studies showed conflictingdata regarding outcomes of targeted temperature management (TTM) for cardiac arrest. The purpose of thismeta-analysis is to systematically determine the effect of TTM on all-cause mortality and neurological outcomesafter cardiac arrest.Methods: We conducted a systematic search for randomized controlled trials in Pubmed, Cochrane &ScienceDirect. Primary outcomes were neurological outcome and all-cause mortality.Results: Nine randomized controlled trials utilizing data for in-hospital and out-of-hospital cardiac arrest were se-lected for meta-analysis. Total number of patients included was 1592. Mortality was lower in targeted tempera-ture management group (OR 0.637, 95% CI 0.436–0.93, p-value 0.019, I2 = 44.78%, n = 1592). Therapeutichypothermia group also demonstrated reduction in poor neurological outcomes (OR 0.582, 95% CI 0.363–931,p-value 0.024, I2 = 56.79%, n = 1567). Subgroup analysis was conducted, after excluding in-hospital cardiac ar-rest patients, and demonstrated reduction in poor neurological outcome (OR 0.562, 95% CI 0.331–0.955, p-value0.033, I2 = 61.78%, n = 1480) and mortality in out-of-hospital cardiac arrest patients (OR 0.674, 95% CI0.454–999, p-value 0.049, I2 = 43.8%, n = 1505).Conclusion: Targeted temperature management after cardiac arrest may be associated with improvement in all-cause mortality and reduction in poor neurological outcome.© 2019 The Authors.
