Comparative Study of LMA Supreme versus I-gel in Patients Undergoing Laparoscopic Surgeries with Positive Pressure Ventilation
Journal Title: Indian Journal of Anesthesia and Analgesia - Year 2019, Vol 6, Issue 2
Abstract
Backround: The main objective of this study is to compare the efficacy of two newer supraglottic airway devices LMA Supreme and I GEL in patients undergoing laparoscopic surgeries with positive pressure ventilation. Materials and methods: A total of 50 patients with 25 in each group (‘LMA Supreme’ or ‘I GEL) undergoing laparoscopic surgery at SMVMCH from October 2014 to May 2016 were included in the study. Based on the score given by the inserting anaesthetist, parameters like ease of insertion, number of insertion attempts, ease of insertion of Ryles tube, airway seal by the device before and after creating pneumoperitoneum and any complications arising after removing the device were assessed. Results: LMA Supreme and I GEL have an equally high successful rate in terms of ease of insertion and both devices have a similar number of attempts for insertion. In terms of ease of insertion of ryles tube, all patients in LMA supreme group were successfully inserted with a ryles tube (Insertion score 1), where as there was some difficulty encountered in inserting the ryles tube in I GEL group. There was no audible leak throughout the period before creating pneumoperitoneum and after creating pneumoperitoneum showing that both devices are equally effective in providing an adequate airway seal with positive pressure ventilation. Both the devices were equally effective in providing airway seal with a minimal increased requirement of tidal volume in I GEL group. Thus inferring both the devices are equally effective in working performance as an effective airway device in laparoscopic surgeries with positive pressure ventilation. Conclusion: Both LMA Supreme and I GEL are equally effective in maintaining adequate airway seal in laparoscopic surgeries with positive pressure ventilation. LMA Supreme is superior over I GEL in terms of ease of insertion of Ryles tube and increased tidal volume requirement in I GEL group for maintaining the ventilation when compared to LMA supreme.
