Effectiveness of Ondansetron and Midazolam in the Prevention of PONV after Thyroidectomy / 대한마취과학회지

ABSTRACT

BACKGROUND: The purpose of this study was to investigate the effectiveness of ondansetron and midazolam in the prevention of PONV after thyroidectomy. METHODS: One hundred nineteen women undergoing thyroidectomy under general anesthesia were randomized to receive midazolam 0.075 mg/kg (Group M, n = 41), ondansetron 4 mg (Group O, n = 39), or normal saline 10 ml (Group C, n = 39) intravenously. The incidence and severity of nausea, vomiting, and pain were assessed as 6 and 24 h after the end of surgery. RESULTS: The incidence of PONV was 34% in Group M, 46% in Group O, and 64% in Group C, which showed a significant difference between Group C and Group M, but not Group O. However, there were no significant differences between groups in pain scores and the incidence of sedation. CONCLUSIONS: We recommend the use of midazolam as an effective antiemetic after thyroidectomy.
