Comparative evaluation of the clinical performance of supraglottic airways- Supreme laryngeal mask airway, I gel and baska mask

Abstract

There are no studies comparing Supreme laryngeal mask airway (LMA), I gel and Baska mask in Indian population. A comparison of the clinical performance of Supreme LMA, I gel and Baska mask was undertaken in this randomized controlled study.The present research was undertaken in 75 patients aged 18 to 60 years who underwent elective surgery for less than 3-hour duration under general anaesthesia. The patients were randomly divided into three groups; Supreme LMA, I gel, and Baska mask. The oropharyngeal leak pressure (OLP) after 30 minutes to loss of spontaneous respiration was the primary objective, whereas the secondary objectives were attempts required for insertion of LMA, ease of gastric tube insertion, time required for gastric tube insertion and post-operative morbidity. The mean OLP of Baska mask group was (28.2 cm HO) as compared to Supreme LMA (25.3 cm HO) and I-gel (24.1 cm HO) groups (p-value = 0.0001). The mean gastric tube insertion time of Baska mask group was (20.7 s) as compared to Supreme LMA (6.7 s) and I-gel (9.6 s) groups (p-value = 0.0001). The three groups were comparable with regards to the number of attempts required, ease of gastric tube insertion and post-operative morbidity.A higher OLP was observed in Baska mass group as compared to Supreme LMA and I-gel. The three devices were similar in terms of attempts required for insertion, ease of gastric tube insertion and post-operative morbidity.
