A Comparative Study of Two Disposable Supraglottic Devices in Diagnostic Laparoscopy in Gynecology

Abstract

ABSTRACT Introduction This prospective study compares the efficacy of two disposable supraglottic airway devices with separate gastric access and integral bite block, the inflatable cuff of the LMA SupremeTM against the noninflatable i-gelTM cuff in providing an adequate seal for laparoscopic surgery. Materials and methods Ninety women of ASA grade I and II undergoing diagnostic laparoscopy with Trendelenburg position were randomly allocated to receive either size 3 LMA Supreme or i-gel. Induction and maintenance protocols were similar and patients were not paralyzed. We compared the airway leak pressure, ease and time to insert the device and a 10 FG nasogastric tube through it, and to note complications if any. Results There was no difference in airway leak pressure between the two devices (24.4 ± 4.0 vs 23.6 ± 3.8 cm H2O, p > 0.05). Forty-one (91%) LMA Supremes and forty (88.8%) i-gels were successfully inserted on the first attempt, with similar ease, and comparable times (13.8 ± 4.9 sec for LMA Supreme vs 14.5 ± 6.7 sec for i-gel; p > 0.05). Gastric tube insertion was easier and achieved more quickly with LMA Supreme compared to i-gel (9.0 ± 3.1 sec vs 14.3 ± 7.5 sec, respectively; p < 0.01), but clinical significance of this finding is questionable. There was blood on removal of four LMA Supremes and three i-gel. Four patients in the LMA Supreme group and one patient in the i-gel group experience mild postoperative sore throat. Conclusion Both LMA Supreme and i-gel are equally effective ventilator devices for diagnostic gynecological laparoscopic procedures. How to cite this article Chattopadhyay S, Goswami S.
