Background: This study was undertaken to compare: The ease of insertion of
LMA when propofol is combined with either IV lignocaine or topical lignocaine
spray, The hemodynamic changes during LMA insertion in both the groups.
Materials and Methods: Type of study is Randomized controlled trial. Study
population is100 ASA physical status 1 and 2 patients of age group 20 to 50
years who underwent various elective surgical procedures. Randomization is
Sealed envelope method. In group A, lignocaine was administered
intravenously; and in Group B, lignocaine aerosol 10% was sprayed to posterior
pharyngeal wall before induction. Classic LMA of appropriate size was inserted.
The ease of insertion of LMA was compared between both groups based on the
incidence of gagging, coughing and laryngospasm. Hemodynamic parameters-
HR, SBP, DBP, MAP, EtCO2 and SPO2 were recorded. Result: In group A,
grades in ease of LMA insertion was excellent/good/poor in 50%/20%/30% of
subjects respectively. In group B, the grades in ease of insertion of LMA was
excellent/good/poor in 60%/30%/10% of subjects respectively. The p value is
0.04. There is a significant difference between both the groups. The
hemodynamic parameters- HR, SBP, DBP, MAP and EtCO2 were significantly
higher in IV lignocaine group during the initial 5 minutes from the beginning of
Anaesthesia. Conclusion: Topical anaesthesia of airway with 10% lignocaine
aerosol before induction, provides excellent ease for inserting LMA
