AbstractWe studied 40 patients undergoing minor gynaecological surgery, anaesthetized in random order with sevoflurane-nitrous oxide or thiopental-fentanyl. Operating conditions, pain, recovery and postoperative nausea and vomiting were assessed. For postoperative analgesia, all patients were given dypiron 1 g intravenous at the end of anaesthesia. Patients and gynaecologists were equally satisfied with both anaesthetic techniques. The time of surgery were higher in patients given sevoflurane, (7 versus 5 minutes) this women had recovery faster (17 versus 72 minutes) became orientated, followed orders (11 versus 19 minutes) and were able to walk (17 versus 60 minutes) significantly (p < 0.05) earlier than those given thiopental. Modified Aldrete scores were also higher in sevoflurane group within the first hour after anaesthesia, there were no differences in woke up (9 versus 12 minutes) vital constants, intrauterine bleeding, pain, and frequency of postoperative nausea and vomiting (10% versus 10%) between the two groups. We conclude that sevofluranenitrous-oxide is preferable to thiopental-fentanyl in ultra-short anaesthesia for minor gynaecological surgery.
