BACKGROUND The purpose of present study was to compare and evaluate both topical lignocaine and intravenous lignocaine for laryngeal mask airway (LMA) insertion prior to propofol. Main objective was to study the conditions for LMA insertion with respect to gagging, coughing, Laryngospasm and No. of attempts for LMA insertion and also study the hemodynamic parameters in both the groups (Heart rate, SBP,DBP, MAP, SpO2) METHODS This study included 60 patients of 30 in each group, ASA I & II day care surgeries were performed in our hospital between 2019 and 2021. Patients were randomized into two groups. Group I received intravenous lignocaine 1.5 mg / kg over 30 seconds and group II received topical lignocaine 40 mg. Conditions of LMA insertion, gagging, laryngospasm, coughing were noted at the time of insertion, ECG, NIBP, SPO2 and ETCO2 were recorded according to scheduled times. RESULTS In conditions of LMA insertion, difference between both the groups was found to be significant, P < 0.05 in groups with first minute rise in heart rate, fall in Systolic blood pressure, diastolic blood pressure, mean arterial pressure was significant. At two minutes and three minutes after the LMA insertion, HR, SBP, DBP, MAP all these parameters changed slightly but these changes were statistically not significant. CONCLUSIONS Prior to Propofol induction, compared to intravenous lignocaine, topical lignocaine 10 % aerosol provided excellent conditions for the insertion of LMA without the use of neuromuscular blockers.
