Attenuation of Hemodynamic Response to Direct Laryngoscopy and Intubation Using 10% Lignocaine Spray : A Clinical Study

Hemodynamic response to Laryngoscopy and Intubation is a well-known problem since long time and there are many studies conducted to attenuate this presser response, the present study is undertaken to study the effect of 10% lignocaine spray for suppressing the cardiovascular responses to tracheal intubation.METHODS: Thirty nine Patients of either sex aged between 20-60years of age, belonging to ASA Grade I and II, undergoing elective surgery requiring General Anesthesia with endotracheal intubation were included for the study.After recording the baseline Heart Rate, Systolic Blood Pressure and Diastolic Blood Pressure lignocane spray 10% meter dose was used to anaesthetise glasoepiglotic fold before premedication.Anaesthesia induced with propofol and succinylcholine to assist direct laryngoscopy and intubation.Heart rate, systolic blood pressure, diastolic blood pressures were recorded after premedication, induction and immediately after intubation.RESULTS: Heart Rate, Systolic blood Pressure, Diastolic Blood Pressure and rate pressure product of 39 patients included in the study were analyzed and compared from baseline parameters to after intubation.CONCLUSION: Study concluded that 10% lignocaine spray is a simple and probably one of the most effective methods in attenuating hemodynamic response to laryngoscopy and intubation.
