A systematic review and meta-analysis of the i-gel (R) vs laryngeal mask airway in children

Abstract

We systematically reviewed randomised controlled trials of the i-gel((R)) vs different types of laryngeal mask airway in children. We included nine studies. There was no evidence for differences in: rate of insertion at first attempt; insertion time; ease of insertion; or gastric tube insertion. The mean (95% CI) oropharyngeal leak pressure was 3.29 (2.25-4.34)cmH(2)O higher with the i-gel, p<0.00001. The relative rate (95% CI) of a good fibreoptic view through the i-gel was 1.10 (1.01-1.19), p=0.02. There were no significant differences in the rates of complications, except for blood on the airway, relative rate with the i-gel 0.46 (0.23-0.91), p=0.02. We concluded that the clinical performance of the i-gel and LMA was similar, except for three outcomes that favoured the i-gel.
