A Randomized Prospective Study to Compare Use of I-GELTM and LMA ProsealTM in Patients undergoing Laparoscopic Cholecystectomy

Abstract

Introduction: With the availability of supraglottic devices in providing effective seal even in conditions of raised airway pressures, use of these devices in laparoscopic surgeries has become popular. Of the various supraglottic devices being used in laparoscopic surgery LMA ProSealTM and i-gelTM airway are commonly used with efficacy. The aim of this study was to compare the use of i-gelTM and LMA ProSealTM in patients undergoing Laparoscopic cholecystectomy. Methodology: This was a prospective randomized, hospital based study conducted at a tertiary care hospital. Adult inpatients of either gender posted for elective laparoscopic surgery were recruited in the study. A total of 100 patients were included out of which 50 each were randomly allocated to either i-gelTM group (Group I) or LMA ProSealTM group (Group P). After randomization, the chosen supraglottic airway device (i-gel/Proseal LMA) was inserted. Airway insertion attempts, time to successful ventilation, Gastric tube placement, Airway sealing quality, Numbers of attempts required for correct placement and complications were recorded and the data was assessed. Results: Demographic data were comparable in the two groups. The Ventilation time was found to be significantly faster with PLMA as compared to i-gel. I-gel and Proseal showed no significant differences in the airway and gastric tube insertion attempts, ventilation success rate, airway sealing pressures, SpO2, EtCO 2, airway sealing quality score and intra abdominal pressures. Conclusion: Both i-gel and Proseal both provide adequate ventilation in laparoscopic cholecystectomy surgeries. Complications such as airway injury and bleeding with Proseal LMA are significantly more as compared to i-gel.
