Comparison of surgical field quality and emergence time during endoscopic sinus surgery using propofol or desflurane: a randomized clinical trial

Objectives: Hypotensive anesthesia is necessary during endoscopic sinus surgery to achieve a bloodless surgical field. The aim of this study was to compare the quality of surgical field using propofol or desflurane anesthesia

---

Methodology: 40 patients of either sex, belonging to ASA physical status I and II, and age group of 18 - 60 years were randomized into two groups to receive either propofol and morphine or desflurane and morphine anesthesia. The target mean arterial pressure [MAP] was kept in a range of 65-75 mmHg. The quality of surgical field was assessed by using a validated scoring system [Fromme category scale] at every 15 min by the same surgeon in all the cases to avoid surgeon's bias

---

Results: The mean category scale value was 2.665 +/- 0.243 in propofol group and 2.200 +/- 0.410 in desflurane group [p=0.000]. The time to emergence was significantly less in desflurane group [9.35 +/- 1.27] as compared to propofol group [14.60 +/- 2.06 min]

---

Conclusion: We conclude that both the propofol and desflurane can be used to achieve a satisfactory surgical field quality but desflurane provides a rapid emergence as compared to propofol
