[Comparison of methylprednisolone and droperidol in the prevention of nausea and vomiting following major gynaecological surgery].

The efficacy of methylprednisolone (MP) (500 or 250 mg) or droperidol 2.5 mg administered i.v., was studied in 200 women undergoing major gynaecological surgery. Following a standardised general anaesthesia technique with intrathecal morphine, the incidence of nausea and vomiting was assessed. The frequency of postoperative nausea and vomiting in the non-treated group was 59% and 35%; the group of MP 500 mg has a significant reduction of nausea and vomiting to 21% and 13%. Droperidol 2.5 mg decreased the incidence of postoperative nausea alone (nausea: 36%, vomiting: 19%). MP 250 mg was not effective in reducing either nausea or vomiting (nausea: 44%, vomiting: 38%). It was concluded that, of the drugs studied, MP 500 mg was most effective in preventing nausea and vomiting after major gynaecological surgery.
