Abstract
OBJECTIVE: The aim of this study was to conduct a meta-analysis to evaluate the efficacy of vasopressin-epinephrine compared to epinephrine alone in patients who suffered out-of-hospital cardiac arrest (OHCA). METHODS: Relevant studies up to February 2017 were identified by searching in PubMed, EMBASE, the Cochrane Library, Wanfang for randomized controlled trials(RCTs) assigning adults with cardiac arrest to treatment with vasopressin-epinephrine (VEgroup) vs adrenaline (epinephrine) alone (E group). The outcome point was return of spontaneous circulation (ROSC) for patients suffering from OHCA. Heterogeneity, subgroup analysis, sensitivity analysis and publication bias were explored. RESULTS: Individual patient data were obtained from 5047 participants who experienced OHCA in nine studies. Odds ratios (ORs) were calculated using a random-effects model and results suggested that vasopressin-epinephrine was associated with higher rate of ROSC (OR=1.67, 95% CI=1.13-2.49, P<0.00001, and total I2=83%). Subgroup showed that vasopressin-epinephrine has a significant association with improvements in ROSC for patients from Asia (OR=3.30, 95% CI=1.30-7.88); but for patients from other regions, there was no difference between vasopressin-epinephrine and epinephrine alone (OR=1.07, 95% CI=0.72-1.61). CONCLUSION: According to the pooled results of the subgroup, combination of vasopressin and adrenaline can improve ROSC of OHCA from Asia, but patients from other regions who suffered from OHCA cannot benefit from combination of vasopressin and epinephrine.
