BackgroundThe Anesthesia planning is an important and determining factor in the amount of intraoperative hemorrhage, which can affect the rate of intraoperative and postoperative complications.ObjectivesIn this study we used two different anesthesia techniques in functional endoscopic sinus surgery (FESS) and compared the amount of hemorrhage in the two groups.Patients And MethodsIn a single-blind clinical trial, 44 patients with ASA class I and II candidate for FESS in Amir-Al-Momenin hospital in Rasht were entered the study and divided into two equal groups randomly. In both groups anesthesia was induced with propofol, remifentanil and cis. atracurium and then, infusion of propofol - remifentanil in the first group and isoflurane plus Remifentanil infusion in the second group was used for maintenance of anesthesia. Systolic blood pressure was maintained about 90 mmHg. Then on the basis of maximum allowable blood loss (MABL) formula, we calculated the percentage of hemorrhage. Finally the patients' hemorrhage was categorized into three groups (< 10%, 10-20%, > 20%). The surgeon's satisfaction from surgical field was calculated according to the Visual Analogue Scale. Then the data was statistically analyzed with T- test.ResultsThere were meaningful differences between average of hemorrhage (propofol group = 155cc, and Isoflurane group = 291.3cc; P = 0.003), and surgeon's satisfaction (propofol group = 1.9 and Isoflurane group = 2.95; P = 0.007).ConclusionsThe amount of hemorrhage in propofol group was less than Isoflurane group and the field condition was better in propofol group than the Isoflurane group.
