Evaluation of the Effect of Propofol-Remifentanil and Propofol-Hydralazine on the Bleeding Volume During Dacryocystorhinostomy Surgery Under General Anesthesia.

Background: The present study was performed to compare the effectiveness of propofol-remifentanil and propofol-hydralazine in inducing controlled hypotension in patients undergoing the dacryocystorhinostomy (DCR) surgery and reducing their bleeding volume during surgery.

Materials And Methods: The present double-blind, randomized clinical trial was performed on 70 patients who were candidates for DCR surgery and divided into two groups. In both the groups, general anesthesia protocol was performed.
