The effects of different anaesthetic methods on nausea-vomiting and recovery in the middle ear surgery.

The aim of this study is to investigate the effects of sevoflurane and propofol anesthesia on postoperative nausea vomiting and recovery in the middle ear surgery. The patients undergoing to middle ear surgery were randomly divided into two groups as Group S ( n=19) and Group P ( n=19). AH the patients are premedicated with 0.1 mg/kg İM midazolam and the induction was done with sevoflurane in Group S and 2.5 mg/kg İVpropofol in Group P. After the blockage with vecuronium 0.1 mg/kg, entübation was performed. Anesthesia maintenance was done with sevoflurane 1-3% in Group S and 8 mg/kg /h IV propofol infusion in Group P and 70% N2O/O2 inhalation in both. At the end of the operation, after quitting the anesthetics, the extubation times, spontaneous eye opening and recovery times were recorded. Postoperative nausea vomiting were evaluated in 2nd, 6th, 12th,18th and 24th hours. There were no significant differences found betvveen the groups according to spontaneous eye opening and recovery times ( p>0.05 ). Nausea-vomiting rate was found to be high in 0-2, 2-6, 12-18 hours in Group S ( p<0.05), but there was no difference in 6-12 hours ( p>0.05). Nausea-vomiting was not seen in any of the groups in 18-24 hours. İn conclusion no differences were found betvveen these anesthesia methods according to postoperative recovery, although nausea-vomiting rates appearently lovver in Group P. For this reason propofol anesthesia was decided to be an alternative for the middle ear surgery which has a high incidence ofpostoperative nausea and vomiting.
