Dehydrobenzperidol as peroperative anti-emetic: most effective administration time

Abstract

206 female patients undergoing curettage or laparoscopy were randomized in 4 comparable groups. Group 1 did not receive dehydrobenzperidol (DHBP), group 2 was given DHBP during premedication, group 3 during induction of anesthesia and group 4 when patients presented symptoms of nausea and/or vomiting. Again, the statistical results confirm the strongly anti-emetic effects of DHBP. Because of the existing trend towards a more beneficial effect of DHBP if given during induction and the avoidance of a possible adverse reaction, administration during induction is to be preferred, at least in non-ambulatory patients.
