Objective: This study was done to compare the effect of preoperative Atenolol with intraoperative Nitroglycerin in patients undergoing FESS Regarding hemodynamic and surgical conditions. Material and Methods: 38 patients of (ASAI) 18-53 years scheduled for FESS were randomly divided into two groups 19 each. Group A patients were premedicated orally with Atenolol 50 mg 3 hours before induction. Group B patients received Nitroglycerin Infusion 1-4 mcg/kg/min titrated to a mean arterial blood pressure of 60-70 mm/Hg. Results: the operative field visibility was better also mean arterial pressure was lower in group B in comparison to group A , while mean heart rate was lower in group A. Conclusion: Nitroglycerin infusion have better quality of surgical field, lesser blood loss, shorter duration of surgery in comparison to premedication with Atenolol, However Atenolol maybe a good alternative when Nitroglycerin infusion is contra indicated or not feasible.
