To determine the anti-emetic effect of ginger as compared to droperidol, 120 patients scheduled to have gynaecological diagnostic laparoscopy as day cases were randomly allocated into placebo, droperidol, ginger and ginger plus droperidol groups to receive either 2 g of ginger or 1.25 mg of droperidol or both. There were no significant differences in the incidences of postoperative nausea which were 32%, 20%, 22% and 33%, and vomiting which were 35%, 15%, 25% and 25% in the four groups, respectively. We conclude that ginger powder, in the dose of 2 g, droperidol 1.25 mg or both are ineffective in reducing the incidence of postoperative nausea and vomiting after day case gynaecological laparoscopy.
