Abstract
INTRODUCTION: Extracorporeal cardiopulmonary resuscitation (ECPR) is increasingly used to treat refractory cardiac arrest, although with variable results in survival and neurological outcomes. The intra-aortic balloon pump (IABP) showed mixed effects on survival in veno-arterial extracorporeal membrane oxygenation. Furthermore, the impact of IABP on survival and neurological outcomes in ECPR recipients has yet to be fully investigated. METHODS: We searched relevant databases for studies concerning ECPR recipients and intra-aortic balloon pump with information on survival and neurological outcomes. The inverse variance method (95 % confidence intervals) was used to determine the odds ratios of outcomes. We decided on a priori use of the random-effects model with the Hartung-Knapp adjustment. RESULTS: We included in our analysis nine cohort studies dealing with a total of 4994 patients. The association of IABP with ECPR was associated with a survival benefit compared to ECPR alone: 1029/3124 (32.9 %) patients survived in the ECPR+IABP group versus 379/1870 (20.2 %) in the ECPR group, OR 1.94, 95 % CI [1.36 to 2.77]. Survival with good neurological outcome was analyzed in 4 studies for 4018 patients. The association of ECPR and IABP was associated with a not significant advantage in survival with favorable neurological outcome compared with ECPR alone: 555/2687 (20.7 %) patients with good neurological outcome in the group of ECPR+IABP versus 149/1331 (11.2 %) patients in the group of ECPR, OR 1.33, 95 % CI [0.61 to 2.92]. CONCLUSIONS: The association of IABP and ECPR significantly increases survival rates compared to ECPR alone. Nevertheless, the impact on favorable neurological outcomes remains uncertain.
