Abstract

Background: Objective of present study to determine that administration of Intravenous Lignocaine prior to propofol is as effective as topically on the posterior oropharynx for LMA insertion.

Methods: 60 patients of age group 16-45years of both sexes, ASA Grade I and II undergoing elective surgeries. Group 1: (n=30) Patients receiving Lignocaine 1.5 mg/kg IV over 30 seconds. Group 2: (n=30) Patients receiving lignocaine aerosol 40 mg topically. Conditions of LMA insertion, gagging laryngospasm ,coughing noted at time of insertion, ECG, NIBP, SPO2 and ETCO2 were recorded according to scheduled times.

Results: In Conditions of insertion, difference between groups reached significance, p<0.05. In groups at first min, rise in heart rate, fall in DSP, SBP and MAP was significant. At two and three minutes post LMA insertion these parameters change slightly but statistically not significant.

Conclusions: Topical Lignocaine 10% aerosol prior to propofol induction provides excellent conditions for LMA insertion without the use of neuromuscular blockages.
