Abstract

Context: Supraglottic airway devices (SGAs) are tools used for airway management in anaesthesia and provide a good alternative to tracheal intubation.Comparison of I-gel and ProSeal LMA (PLMA) was done because of time taken for insertion, fiberoptic view of the larynx, ease of Ryle’s tube insertion, and post-operative sore throat assessment. Methods and Material: In the present prospective, randomized study instead of manner, 60 adult patients of the American Society of Anaesthesiologists I-II of either gender between 18 and 60 years presenting for an elective surgical procedure, under general anaesthesia were enrolled. The airway was secured using either the I-gel or PLMA. An experienced non-blinded anaesthesiologist inserted appropriate sized I-gel or PLMA in patients using standard insertion technique and compared both devices in terms of time taken for insertion, effective seal, fibre optic view of the larynx, number of attempts, and hemodynamic changes during insertion. Results: The time required for insertion of I-gel was lesser (14.32 ± 1.23 and 20.23± 1.82s in Group I and Group P, respectively; P < 0.001). The numbers of attempts for successful insertions were comparable and in the majority, the device was inserted in the first attempt. The fiber optic view of glottis was better with I gel (p-value=0.048),hemodynamic changes and incidence of complications were comparable in both groups. Conclusions: The time required for successful insertion of I-gel was shorter in adult patients undergoinga surgical procedure under general anesthesia on controlled ventilation.The fibre optic view of the glottis was better with the proseal indicating better utility as a conduit for intubation.
