Comparison of sevoflurane and propofol anesthesia on surgical field and recovery characteristics in patients undergoing endoscopic sinus surgery

ABSTRACT

The endoscopic surgical procedures have been developed specifically for the areas located in the key points of the lateral nasal wall. Small areas of bleeding in the operative field can reduce visibility and considerably impair surgical conditions. This randomized, prospective study was performed to compare propofol and sevoflurane based anesthesia on the surgical field in patients undergoing endoscopic sinus surgery and to compare the recovery characteristics between them. Patients and Methods Forty patients ASA I and II, scheduled for elective endoscopic sinus surgery were randomly divided into two equal groups to receive either propofol or sevoflurane as a maintenance anesthetic. Propofol was the induction agent in both groups. Group 1 received propofolnitrous oxide for maintenance of anesthesia [Propofol group] while group 2 patients received sevoflurane-nitrous oxide [Sevoflurane group]. in this study, the attending otorhinolaryngological surgeon was unaware of the type of anesthesia administered immediately after the operation, the surgeon rated surgical conditions [bleeding from the surgical field] on a visual analogue scale [0-10 cm] and on a verbal rating scale. Also we compare the two groups [15 regards recovery profile [extubation time, command response, orientation time, and time until eligible for discharge]. Blood pressure was not different between the two groups, but heart rate was lower in the intravenous anesthesia group. Surgical conditions were rated to be significantly better during anesthesia with propofol compared with sevoflurane. There were no differences in the recovery character between the two groups. Total intravenous anesthesia with propofol has the advantage of decreased bleeding compared with sevoflurane anesthesia. Therefore, making endoscopic surgery technically easier and safer by improving endoscopic visualization of the surgical field. Both sevoflurane and propofol have comparable recovery profiles
