Research synthesis was conducted when at least 4 studies were available for an outcome, which limited the analysis of major bleeding events and neurologic outcomes. Benefit of thrombolytic therapy in survival to discharge showed a moderate beneficial effect (OR = 2.79, 2.11–3.69) in the retrospective study analysis while in the prospective study analysis no statistically significant benefit was found (OR = 1.27, 0.77–2.10). Benefit of thrombolysis in the rate of ROSC was not statistically significant in the prospective analysis (OR = 1.59, 0.92–2.76, p = 0.138) as well as survival at 24 hours (OR = 1.17, 0.72–1.71).Conclusions: The widespread use of thrombolytics in patients with non-traumatic cardiac arrest does not seem to improve major outcomes, including survival to discharge. However, the modest benefit found in the retrospective study analysis suggests a subgroup of patients that may benefit from this therapy.Keywords: Thrombolytic therapy, cardiac arrest, advanced cardiac life support, cardiopulmonary resuscitation, tissue plasminogen activator ER -
