Comparison of Two Supraglottic Airway Devices in Maintaining Airway for Short Surgeries

Abstract

Objective: To find the better supraglottic airway device in terms of advantages, and complications, in short surgeries following anesthesia and paralysis.
 Study Design: Quasi-experimental study
 Place and Duration of Study: Combined Military Hospital Okara and Armed Forces Institute of Urology, Rawalpindi Pakistan, from July 2018 to July 2020.
 Methodology: Prospectively, 130 American Society of Anesthesiologist (ASA) 1, 2, and 3 patients, aged 15-60 years, scheduled for short urology or gynecological procedure were randomly divided into Group LMA (Group L, n=65) or i-gel group (Group G, n=65). Laryngeal mask airway and i-gel were inserted in respective groups after anesthesia induction and muscle paralysis. The parameters compared were: simplicity of insertion, time taken for insertion, insertion attempts, device exchanged, and complications rate of each device. The data thus obtained was analyzed with SPSS-16.
 Results: LMA group was similar to i-gel group for gender distribution 68 (52%) vs. 62(47%) and surgery type 60 (urology 46.2%) vs. gynecology 70 (53.8%). The successful insertion rate at first attempt (38.4% vs. 40.7%) was similar in both devices. The device was changed in 3.07% of i-gel patient’s vs. 6.92% LMA group patients, and complication rate was not substantially different in either group (i-gel 5.3% vs. LMA 6%). The insertion time was less in i-gel group (17.62 sec ± 6.41 vs.22.06 sec ±7.92) which was statistically significant p≤0.05.
 Conclusion: LMA and i-gel are the two supraglottic devices for maintaining airways with different indications from emergency lifesaving to routine surgical procedures but their use in situations like difficult.......
