[A comparison of the incidence of postoperative nausea and vomiting after propofol-fentanyl anesthesia and that after nitrous oxide-isoflurane anesthesia].

We compared the incidence of postoperative nausea and vomiting after total intravenous propofol-fentanyl anesthesia (TIVA group) and that after thiamylal-nitrous oxide-isoflurane anesthesia (GOI group) in 60 ASA physical I and II patients for elective abdominal simple total hysterectomy. When the patients returned to the ward, the incidence of nausea was lower in TIVA group than in GOI group (P < 0.05), but no difference was found in the incidence of vomiting between the two groups. There were no differences in the incidence of nausea and vomiting 6 hours after the operation and on the next morning between the two groups. Postoperative pain scores were similar between the two groups, while total postoperative evaluation scores (nausea, vomiting, pain, fever, and sleep disturbance) were lower in TIVA group (P < 0.05). We conclude that TIVA with propofol-fentanyl reduced the incidence of nausea and improved total evaluation scores in the immediate postoperative period.
