Surgeries involving general anaesthesia where airway manipulation occurred during laryngoscopy and endotracheal intubation produces stimulation of epipha1ynx and laryngopharynx giving rise to hae1nodynatnic alteration due to catecholamine surge or response. Haemodynamic changes are accentuated in high risk cardiac patient. After obtaining approval from the institutional ethical committee patients fulfilling the inclusion/exclusion criteria were included in the study after obtaining informed consent. A preanesthetic evaluation of history of surgical and medical illness, drug allergies previous anaesthetic exposure and Baseline investigations of blood, ECG, radiograph of chest and airway examination was done. Patient was kept nil by mouth for at least 8hrs prior to surgery. All patients were premedicated with injection Pantoprazole 40mg (IV) one hour prior to surgery. Preoperative vital parameters like baseline pulse, blood pressure were noted. Systolic blood pressure in significantly lower in Group D patient after 40 minutes of intubation continues to be low at 6th, 8th, 10th, 15th and 20th minutes compared to Group C.
