Comparison of LMA Supreme and Endotracheal tube in Laparoscopic Cholecystectomy
LMA Supreme and Endotracheal tube in Laparoscopic Cholecystectomy
Background: Second generation Supraglottic airway devices such as LMA-S have enhanced features to answer some of the concerns raised due to laparoscopic abdominal procedures. The present study was undertaken to compare the efficacy and safety of LMA-Supreme (LMA-S) and Endotracheal Tube (ETT) in patients undergoing laparoscopic cholecystectomy in general anesthesia. Subjects and Methods: 60 patients were randomly allocated into two groups of 30 each. In group 1& 2, we have used LMA-S and ET tube for securing airway. We have assessed time used in device insertion, difficulty in insertion, heart rate, MAP, SPO2, intraabdominal pressure variation, ventilatory parameters and side effects. Results: We had found significant difference of heart rate and MAP between the groups at different times (p<0.05). Time taken for insertion of device was significantly less in group 1 than group 2 (14 2 vs 18.2 2, p<0.001). Side effects were found comparable between the groups. Conclusion: LMA-S and Endotracheal Tube (ETT) both of them show similar efficacy during laparoscopic surgery under general anaesthesia and controlled ventilation. So LMA-S can be used as a effective alternate to ET tube.
