ABSTRACT
Background and Aim: Several clinical studies have been performed on supraglottic airway devices to check for the advantages over the latest versions. Comparison of classic LMA (cLMA) and i-gel is yet to be explored further to optimize the use of airway devices.
Methodology: A prospective randomized study was conducted for two years in a tertiary care hospital. Selected 60 patients were divided equally into two groups, C-LMA (group 1) and i-gel (group 2). Both devices were compared with respect to ease of insertion, number of attempts for insertion, airway leak pressure, hemodynamic changes and complications.
Results: There was no observed statistical significance in both the groups regarding age, sex, body weight, ease of insertion, number of attempts, basal heart rate, SBP, DBP, MAP, SpO2 and adverse effects. The mean time duration of insertion was 23.2 ± 7.14 in cLMA and 16.67 ± 4.2 in i-gel which was statistically significant (p=0.001). Airway leak pressure was significantly higher in i-gel group (p=0.001) in the present study.
Conclusion: Both the devices are safe and good in performance with respect to ease of insertion, hemodynamic changes and pharyngolaryngeal morbidity. Mean time duration was less for i-gel which is easier method to perform. A significant gastric insufflation was low in i-gel over c-LMA.
