To study the efficacy of ginger in prevention of nausea and vomiting after outpatient gynecological laparoscopy. Double blind randomized controlled trial. Department of Obstetrics and Gynecology, Thammasat Hospital, Faculty of Medicine, Thammasat University. From January, 2001-December, 2001, 80 patients who underwent outpatient gynecological laparoscopy were randomly allocated into group A (n = 40) and group B (n = 40). The patients in group A received 2 capsules of ginger (1 capsule contain 0.5 g of ginger powder) 1 h before the procedure while the patients in group B received the placebo. The visual analogue nausea scores (VANS) and vomiting times were evaluated at 2, 4 and 24 hours after operation. There was a significant difference in the incidence of the nausea between group A [12 (30%)] and group B [23 (57.50%)]. The VANS was lower in group A than in group B at 2 and 4 hours (p < 0.05). No difference of VANS at 24 hours was found in both groups. Incidence and frequency of vomiting in group A were lower than group B but there were not statistically different. From our data, ginger is effective in prevention of nausea after outpatient gynecological laparoscopy.
