Abstract

Ambulatory surgery is upcoming in all parts of the world as life becomes more fast pace and time is a limited commodity. In this setting general anaesthesia using the Laryngeal Mask Airway is widely used. Laryngeal Mask Airway insertion is accomplished using Propofol as it helps blunt the laryngeal reflexes well, when compared to other induction agents.
Materials and Methods: The study was        predominantly done in the day care theatre, as this is where most number of Laryngeal Mask  Airways are used in a day. The required sample size to show a difference in the insertion conditions
Results: The following results were obtained from the study. Group I refers to placebo which was saline, Group II refers to 0.1mg/kg of Succinylcholine and Group III refers to 0.25mg/kg of Succinylcholine. Adequate sample sizewas attained with a total of 283 patients. Informed consent was taken from all patients. Group I and II had 95 patients each, and Group III 93 patients. All patients were ASA I or II. None of the patients had a difficult airway.
Conclusion: This study concludes that a low dose of Succinylcholine does facilitate insertion of the Laryngeal Mask Airway. The ideal dose is 0.25mg/kg of Succinylcholine. 0.1mg/kg is not sufficient and is associated inadequate jaw relaxation and does not always provide smooth insertion conditions.
