Comparison between Propofol and Thiopentone for Laryngeal Mask Airway Insertion in Day Care Surgery

Background: Insertion of Laryngeal Mask Airway (LMA) requires an adequate depth of anesthesia. Optimal insertion conditions and hemodynamic stability during LMA insertion are mainly influenced by the choice of the intravenous induction agent. Propofol was recommended as a standard induction agent for LMA insertion. Objective: To assess the effectiveness of thiopentone compared to propofol on LMA insertion. Material and Methods: A prospective study conducted at tertiary care hospital in department of Anaesthesia from March 2019 to April 2020 in 80 patients randomized into propofol group (Group A) and thiopentone group (Group B). Result: There was easy insertion of LMA in all the patients of group A whereas in group B satisfactory conditions were seen in 8 patients for insertion of LMA. This result was found statistically significant (<0.001) though no insertion failure was noticed in either groups. Conclusion: This study demonstrated that for smooth insertion of LMA Thiopentone sodium is a cost effective and safe alternative for Propofol.
