Design outcomes

Primary

MeasureTime frame
To compare the change in mean blood pressure (MBP)/mean arterial pressure (MAP) from pre-intubation to 1 min post intubation in the two groupsTimepoint: preopeartive baseline value, pre intubation, 1 min after intubation

Secondary

MeasureTime frame
1) ?Systolic BP/Diastolic BP/Mean BP pre-intubation and at 3, 5 minutes post-intubation. 2) ?Heart rate pre-intubation and at 1, 3, 5 minutes post-intubation. 3) Effect of time taken for laryngoscopy and intubation on hemodynamic response. 4) Incidence of postoperative sore throat. 5) Any adverse event related to the procedure like coughing or aspiration.Timepoint: 1, 3 and 5 min after intubation from preintubation values Postoperative period
