A Systematic Review and Meta-analysis Unveiling the Pivotal Role of Extracorporeal Membrane Oxygenation (ECMO) in Drug Overdose Treatment Optimization.

Objective: The present study aimed to evaluate the clinical benefits and drawbacks of administering ECMO/ECLS therapies to drug-intoxicated patients. Methods: From inception until April 30, 2024, an extensive search was performed on four main databases: PubMed, Web of Science, Cochrane Library, and EMBASE. There was no restriction on the search period. Only the studies that reported survival to hospital discharge rates, adverse events, and the utilization of ECMO/ECLS in the treatment of intoxicated patients were included. On the other hand, articles that did not report adverse events or hospital discharge rates as outcomes, as well as studies published in languages other than English, were excluded. The evaluated outcomes were the rate of survival to hospital discharge rate and the incidence of adverse events associated with ECMO therapy. The Newcastle Ottawa scale was employed to appraise each study to determine its methodological quality. The Comprehensive Meta-Analysis (CMA) software (version 3.0) for statistical analysis was used, with the random effects model (due to high heterogeneity among the studies) and a 95% confidence interval. Results: From a total search of 2216 search results, only 10 studies were included. The pooled analysis from 10 studies indicated that ECMO therapies among drug-overdosed/poisoned patients were associated with a significant survival to hospital discharge rate of 65.6% ([95% CI: 51.5%-77.4%], Conclusion: Despite various health complications, extracorporeal membrane treatment enhanced survival to hospital discharge with good neurological outcomes. Hence, it was a viable, effective, and feasible alternative for managing drug-induced intoxication in patients.
