COMPARISON OF I-GEL WITH PROSEAL LMA IN ADULT PATIENTS UNDERGOING ELECTIVE SURGICAL PROCEDURES UNDER GENERAL ANAESTHESIA WITHOUT PARALYSIS

Abstract

Comparison Of I-gel With Proseal Lma In Adult Patients Undergoing Elective Surgical Procedures Under General Anaesthesia Without Paralysis Objective: Supraglottic airway devices (SADs) have been widely used as an alternative to tracheal intubation during general anaesthesia. They are easily inserted, better tolerated, with fewer hemodynamic changes. This study compares the efcacy of two supraglottic devices (LMA Proseal and I-gel) in elective surgical procedure under general anaesthesia without paralysis. Material and Method: A prospective randomized study was conducted on 40 patients who were posted for elective short surgical procedures under general anaesthesia. They were randomly divided into two groups of 20 patients each, Group I (I-gel) and Group P (PLMA). All the patients were induced with general anaesthesia and the planned SAD was inserted with head in neutral position. Ease of insertion, number of insertion attempts, oropharyngeal seal pressure and incidence of adverse effects were assessed. Results: I-gel was signicantly easier to insert than Proseal (P < 0.05). The mean time for insertion was more with Group P (40.8±09.61 secs) than with Group I (29.63±08.13 secs). Although the airway sealing pressure was signicantly higher with Group P (26.63±1.31 cm of H2O), the airway sealing pressure of Group I (20.97 ± 2.14 cm of H2O) was within normal limit. The success rate of rst attempt insertion was more with Group I. There was no evidence of airway trauma, regurgitation, and aspiration. Sore throat was signicantly more evident in Group P. Conclusion: I-Gel is better supraglottic device with acceptable airway sealing pressure, easier to insert, less traumatic with lower incidence of sore throat. Hence, I-gel is better alternative than Proseal LMA.
