    Abstract:
    Second-generation supraglottic airway devices i-gel (Intersurgical Ltd) and LMA ProSeal (Teleflex Inc) are designed for a superior airway seal with a high success rate in adults. This study compared the efficacy of i-gel and LMA ProSeal (sizes 1, 1.5, and 2) as an airway device in a pediatric population, especially infants. The study included 163 ASA class 1 and 2 children, aged up to 10 years and weighing 2 to 25 kg, undergoing elective surgeries lasting less than 1 hour under general anesthesia on spontaneous respiration. Participants were randomly assigned to 2 groups: i-gel and LMA ProSeal. With each device, the ease of insertion, time of insertion, manipulations required for placement of the device, and oropharyngeal leak pressure were recorded. A lubricated gastric tube of the recommended size was passed through each device, and ease of insertion was noted. At the end of surgery, the device was removed and complications were noted, including laryngospasm, breath holding, and blood-stains. Mann-Whitney U test and χ2 tests were used to compare collected data. Both devices were found to be comparable in effectively securing the airway in children, even in infants. The insertion time was significantly faster with i-gel.
