Abstract Background: Controlled hypotension is performed in order to reduce blood lossand the need for transfusion duringthe surgery and to improve visibility of the surgical site by decreasingthe arterial pressure until hypotension is reached. Objective: To compare magnesium sulphate and nitroglycerin with propranolol during middle ear surgery in terms of regarding their efficiency in inducingdeliberate hypotension and providinga better surgical field exposureduring middleear surgery. It also compared the influence of their use of postoperative pain and recovery time. Patients and Methods: Forty adult patients undergoing middle ear surgery were included. Patients were randomly divided into two equal groups. Patients were assigned to receive magnesium sulphate (M group) and nitroglycerin with propranolol (N group) from the period of Jan 2018 to August 2018. ASA physical status I, age group ranged from 18to 60. Results: This study included forty adult patients age ranged 18 to 60 undergoing middle ear surgery was included. Patients were randomly divided into two equal groups. Patients were received magnesium sulphate (M group), or nitroglycerin and propranolol (N group). |
