Comparison of clinical performance of I-Gel with LMA-Proseal in elective surgeries under general anesthesia

Abstract

Aim : To compare insertion characteristics of two different supraglottic devices [I-gel and LMA-Proseal] and to observe any associated complications. Materials and Methods : This prospective, randomized study was conducted in 60 patients [Group A- LMA-Proseal (n = 30) and Group B - I-Gel (n =30)] of ASA grades I/II, of either sex in the age group 18-60 years. Both groups were compared with respect haemodynamic response, success rate of insertion, time taken for insertion, ease of gastric tube placement, airway trauma by post operative blood staining of the device, tongue, lip and dental trauma and 24 hours after surgery we watched for sore throat, hoarseness and dysphonia. Result : Haemodynamic response was comparable in both the groups (p >0.05). Mean insertion time for the I-gel (11.47 1.914 sec) was significantly lower than that of the PLMA (13.53 3.92 sec) (P = 0.0002). I-gel was easier to insert with a better anatomic fit. The success rate at first attempt of insertion were 29/30 (96.67%) in for I-gel and 28/30 (93.3%) for LMA - ProSeal (P=0.0002).Ease of gastric tube insertion was significantly higher in the I-gel group (P = 0.116). Blood staining of the device (P= 0.609) and tongue, lip and dental trauma (P= 0.561) and complications 24 hrs after surgery was more with Group A. Conclusion: I-Gel is better than LMA-Proseal in terms of faster insertion and ease of insertion with a low incidence of pharyngolaryngeal morbidity
