Clinical Trial Summary

Postoperative nausea and vomiting (PONV) is unpleasant and increases health care costs. Despite modern techniques and prophylaxis, PONV rates remain high after laparoscopic bariatric surgery. We aim to reduce PONV after laparoscopic bariatric surgery using aprepitant with a similar scheme used for emetogenic chemotherapy.


Clinical Trial Description

Postoperative nausea and vomiting (PONV) is not only a disturbing and unpleasant experience for the patient, it also increases length of post anaesthesia care unit (PACU) and hospital stay. In addition, PONV increases the risk for unplanned admission, risk for complications and in the end, health care costs. Risk factors have been identified more than 20 years ago by Apfel et. al., whose screening score has been widely implemented to augment perioperative prophylaxis. But despite modern anaesthetic techniques and combined antiemetic prophylaxis, PONV rates remain high in patients at high risk for PONV: in a recent retrospective study in female patients after laparoscopic bariatric surgery, up to 68% suffered from PONV during the first 48 hours after surgery despite triple antiemetic prophylaxis. While aprepitant is prescribed for three consecutive days after chemotherapy, there is no study so far evaluating the effect of a second dose of aprepitant 24 hours after surgery to prevent the increase in PONV after PACU discharge. We hypothesise, that adding two scheduled doses of aprepitant (2 hours before and 24 hours after surgery) to a twofold antiemetic regimen will significantly reduce cumulative PONV in the first 48 hours after laparoscopic bariatric surgery in patients with moderate to high risk for PONV. ;
