Comparison of palanosetron and dexamethasone with ondansetron and dexamethasone for prevention of nausea and vomiting after operation in cancer patients receiving opioid based pain relief medicine
- Conditions
- Cancer patients posted for ovarian cancer surgery

- Brief Summary
Postoperative nausea and vomiting (POVN) is considered one of the most unpleasant postoperative discomforts and leads to serious complications of aspiration of gastric contents, suture dehiscence, esophageal rupture, subcutaneous emphysema, or pneumothorax. The incidence of PONV is 30-40% in normal populations and touches a peak of 75-80% in certain high-risk groups.The use of opioid-based intravenous-patient controlled analgesia (IV-PCA) for controlling postoperative pain has become widespread. Yet while IV-PCA is effective in controlling postoperative pain, continuous administration of opioid can cause or aggravate PONV. PONV is the most common reason why patients choose to stop IV-PCA. Ondansetron is the first 5-HT3 antagonist, used alone or in combination for the prophylaxis due to its lower cost. Palonosetron is a second generation 5-HT3 antagonist with a unique chemical structure and longer half- life of 40 hours. It is found to be very effective in chemotherapy induced nausea and vomiting as well as PONV. Dexamethasone with a 5-HT3 antagonist is an attractive combination, because ondansetron is most effective against early vomiting, whereas dexamethasone is effective against both early and late (2–24 h) nausea and vomiting, its late efficacy being pronounced.
