  1. Preoperative hemodynamics measurement (regarding heart rate and mean blood pressure) showed no significant difference between the two groups. Overall, the mean intraoperative heart rate and MAP in the fentanyl group remained significantly higher statistically during the entire infusion period than that in the lidocaine group (p < 0.001) but within clinically acceptable range. During the recovery period, heart rate and Mean blood pressure showed higher levels in fentanyl group in comparison to lidocaine group with significant difference of p value < 0.001.
