Abstract

Background: Decrease of bleeding is of significant importance in keeping the patient’s hemodynamic stabilized, and also in creating a blood-free field with a good vision for the surgeon. The purpose of this study was to compare between the three Isoflurane, Sevoflurane and Propofol+ Remifentanil drugs in terms of hemodynamic status and also bleeding in controlled hypotension, during lumbar spine surgery. Methods: This study was conducted as a randomized clinical trial among 99 patients undergone elective spinal surgery. The patients were randomly allocated into three groups. Group I: Patients received continuous infusion at a rate of 100-200 μg/kg/min propofol with 0.1 μg/kg/min Remifentanil. Group II: Patients received concentration of isoflurane between 1 to 2%. Group III: Patients received concentration of sevoflurane between 1 to 2%. The amount of hemorrhage, hemodynamic changes and Surgeon’s Satisfaction were measured and recorded. Results: There was statistically significant decrease of the bleeding in both propofol and sevoflurane groups as compared to isoflurane group(360.83 ml, 302.50 ml and 690.00 ml respectively) (p
