The objective of this study was to compare the impact of amiodarone and lidocaine on survival and neurological outcomes following cardiac arrest.A systematic review of randomized controlled trials (RCTs) as well as cohort and cross-sectional trials was undertaken, adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Potential relevant studies were searched in databases, including PubMed, Embase, Cochrane Library, and Web of Science, from the beginning of databases to February 15, 2024.Outcomes assessed in this study were survival to hospital discharge, survival to hospital admission or 24 hours, favorable neurological outcomes, and return of spontaneous circulation (ROSC). A total of seven studies (five observational and two RCTs) were included in this meta-analysis encompassing 19,081 patients with cardiac arrest. Pooled analysis showed no difference between amiodarone and lidocaine in terms of survival to hospital discharge(odds ratio (OR): 0.88, 95% confidence interval (CI): 0.75 to 1.04), ROSC (OR: 0.94, 95% CI: 0.84 to 1.05, p-value: 0.25), favorable neurological outcomes(OR: 0.88, 95% CI: 0.66 to 1.17, p-value: 0.38), and survival to 24 hours(OR: 0.82, 95% CI: 0.55 to 1.21, p-value: 0.31).While lidocaine demonstrated a slight survival advantage, the differences were statistically insignificant. Similarly, no significant variations were observed in ROSC incidence, neurological outcomes, or survival at 24 hours. These findings align with current guidelines but underscore the necessity for further rigorous RCTs to provide conclusive recommendations.
