Comparison of oropharyngeal leak pressure and clinical performance of LMA ProSeal and i-gel (R) in adults: Meta-analysis and systematic review

초록

Background A meta-analysis and systematic review of randomized controlled trials to compare the oropharyngeal leak pressure (OLP) and clinical performance of LMA ProSeal (Teleflex (R) Inc., Wayne, PA, USA) and i-gel (R) (Intersurgical Ltd, Wokingham, UK) in adults undergoing general anesthesia. Methods Searches of MEDLINE (R), EMBASE (R), CENTRAL, KoreaMed and Google Scholar (R) were performed. The primary objective was to compare OLP; secondary objectives included comparison of clinical performance and complications. Results Fourteen RCTs were included. OLP was significantly higher with LMA ProSeal than with i-gel (R) (mean difference [MD] -2.95cmH(2)O; 95% confidence interval [CI] -4.30, -1.60). The i-gel (R) had shorter device insertion time (MD -3.01s; 95% CI -5.80, -0.21), and lower incidences of blood on device after removal (risk ratio [RR] 0.32; 95% CI 0.18, 0.56) and sore throat (RR 0.56; 95% CI 0.35, 0.89) than LMA ProSeal. Conclusion LMA ProSeal provides superior airway sealing compared to i-gel (R).
