  • Different airway management strategies in out-of-hospital cardiac arrest: a systematic review

    ObjectiveTo compare the effects of different airway management strategies on outcomes of patients with out-of-hospital cardiac arrest (OHCA).MethodsWe searched PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, and WanFang Data for relevant studies comparing the influence of different airway management strategies on outcomes of OHCA patients. The deadline was up to 31st May, 2019. Grading of Recommendations Assessment, Development and Evaluation system 3.6 was used for quality assessment, and RevMan 5.3 software was used for meta-analysis. Odds ratio (OR) and 95% confidence interval (CI) were used to conduct the comparison. Results A total of 20 studies were finally enrolled, including 880 567 OHCA patients. Compared with supraglottic airway (SGA), bag-valve mask (BVM) improved the rate of survival to discharge of OHCA patients [OR=1.45, 95%CI (1.01, 2.08), P=0.04], while the rate of return of spontaneous circulation (ROSC) was not improved (P>0.05); in the subgroup analysis, BVM and SGA had similar effect on the rate of ROSC and the rate of survival to discharge in Asian countries (P>0.05), while BVM performed better than SGA in the two rates in European and American countries. BVM and endotracheal intubation (ETI) had similar effect on the two rates (P>0.05). In Asian countries, ETI performed better than BVM in the rate of ROSC [OR=0.63, 95%CI (0.49, 0.81), P=0.000 3], and there was no statistically significant difference in the rate of survival to discharge between ETI and BVM (P>0.05); while in European andAmerican countries, BVM performed better than ETI in the rate of survival to discharge [OR=3.10, 95%CI (2.69, 3.56), P<0.000 01], and there was no statistically significant difference in the rate of ROSC between ETI and BVM (P>0.05). Compared with SGA, ETI improved the rate of ROSC [OR=0.68, 95%CI (0.62, 0.76), P<0.000 01] and the rate of survival to discharge [OR=0.89, 95%CI (0.81, 0.98), P=0.02]. In Asian countries, ETI performed better than SGA in the two rates (P<0.05); while in European and American countries and New Zealand, ETI performed better than SGA in the rate of ROSC (P<0.05), but there was no statistically significant difference in the rate of survival to discharge (P>0.05). Conclusions Different airway management strategies have differente effects on OHCA patients. The optimal airway management strategy when rescuing OHCA patients might be selected based on local emergency medical service system conditions.
