[Prevention of postoperative nausea and vomiting with highly selective 5-HT3 serotonin receptors antagonists during different types of surgery].

A prospective study was conducted to examine the efficacy of highly selective, 5-HT3 serotonin receptor antagonists (Zofran, 4 mg; Latran, 4 and 8 mg; Navoban, 2 and 5 mg) during plastic and abdominal (endoscopic and routine) interventions in 165 patients aged 14 to 77 years who had ASA Classes I-III. The drugs caused no adverse reactions and were effective in controlling postoperative nausea and vomiting (PONV) after surgery under total intravenous anesthesia. In plastic surgery, Navoban, Zofran, and Latran controlled PONV in 94, 81, and 70% of cases, respectively. In abdominal surgery, Zofran (4 mg) and Latran (4 mg and 8 mg) did this in 87, 80, and 90% of cases, respectively. Risk factors for PONV are analyzed. The pathophysiological aspects of PONV and practical approaches to making an antiemetic strategy are discussed.
