Comparison of supraglottic airway devices in laparoscopic surgeries: A network meta-analysis.

Abstract

STUDY OBJECTIVE\nTo review all randomized controlled trials (RCTs) on supraglottic airway devices (SADs) used in laparoscopy and compare their oropharyngeal leak pressure (OLP) and peak inspiratory pressure (PIP) before and after pneumoperitoneum, and success rate of gastric tube insertion rate.\n\n\nDESIGN\nSystematic review and network meta-analysis of RCTs.\n\n\nSETTING\nLaparoscopic surgeries using SADs.\n\n\nPATIENTS\nWe searched MEDLINE, EMBASE, Web of Science, Cochrane Central Register of Controlled Trials, and Google Scholar databases to detect all relevant RCTs on SADs for laparoscopic surgery published until March 2018.\n\n\nINTERVENTIONS\nUse of different SADs.\n\n\nMEASUREMENTS\nThe primary endpoint was OLP before and after pneumoperitoneum. The secondary endpoints were PIP before and after pneumoperitoneum and gastric tube insertion success rate.\n\n\nMAIN RESULTS\nTwenty-six studies involving 2142 patients with eight different SADs were evaluated. According to surface under the cumulative ranking curve value, the OLP before pneumoperitoneum was the highest in Ambu AuraGain (95.7%), followed by Laryngeal Mask Airway ProSeal (77.3%) and Streamlined Liner of the Pharynx Airway (75.6%); after pneumoperitoneum, the pressure was the highest in i-gel (95.8%). PIP was the highest in Ambu AuraGain (80.9%) before pneumoperitoneum and i-gel (69.4%) after pneumoperitoneum.\n\n\nCONCLUSION\nAlthough all SADs available were not evaluated, and further studies are needed to establish our results, OLP was the highest in Ambu AuraGain before pneumoperitoneum and i-gel after pneumoperitoneum.
