Aims and Objectives: The aim of this study was to compare Fentanyl, Lignocaine and Placebo for attenuation of cardiovascular response to direct laryngoscopy and intubation during General Anaesthesia. Methodology: After obtaining ethical committee approval and taking written informed consent from patients this study was done at Maheshwara medical college & hospital in 75 patients of ASA grade I aged between 25-45 years coming for elective surgical procedures. The patients were allocated into three groups of 25 each: Group F ? Fentanyl 2 g/kg body weight Group L - Lignocaine 1.5 mg/kg body weight Group N - Normal saline 3 ml as placebo Observation and Results: The heart rate, systolic and diastolic blood pressure responses during laryngoscopy and intubation have shown significant difference with fentanyl and lignocaine when compared with the placebo group. Conclusion: This study confirms that Fentanyl attenuates both heart rate and blood pressure responses to laryngoscopy and intubation, whereas with Lignocaine blood pressure was effectively controlled than heart rate.
