OBJECTIVE To compare the results of Tropisetron, Metoclopramide and placebo on postoperative nausea and vomiting in patients undergoing minilaparotomy cholecystectomy. SETTING Patients operated for minilaparotomy cholecystectomy in two private hospitals in Karachi.

Using N1E-115 neuroblastoma cells as an experimental model, we have examined if four commonly used i.v. anaesthetic induction agents interact with 5-HT3 receptors. Specifically, we tested the hypothesis that the antiemetic effects of propofol may result from 5-HT3 receptor antagonism. Binding of tropisetron (a 5-HT3 selective reference compound), etomidate, ketamine, thiopentone and propofol to...

The incidence of nausea and vomiting after radiotherapy is often underestimated by physicians, though some 50-80% of patients may experience these symptoms. The occurrence of radiotherapy-induced nausea and vomiting (RINV) will depend on radiotherapy-related factors, such as the site of irradiation, the dosing, fractionation, irradiated volume, and radiotherapy techniques. Patients should recei...

Postoperative nausea and vomiting (PONV) is one of the most unpleasant and distressing symptoms which follow anaesthesia and surgery and lead to serious postoperative complications. PONV commonly occurs within 24 hours after surgery and can occur following general, regional, or local anaesthesia. Patients undergoing major abdominal surgery are especially prone to PONV, with reported incidences ...

Beta adrenergic receptor antagonists and antiemetic muscarinic receptor antagonists are useful for mental health in primary care and family medicine settings, as they provide favorable risk/benefit profiles, and especially so relative to benzodiazepines. Beta blockers (e.g., propranolol) prescribed off-label have been known for decades to provide some, albeit limited, anxiolytic benefit for pat...
