title: Management of postoperative nausea and vomiting in women scheduled for breast cancer surgery.
abstract: Breast cancer surgery performed under general anesthesia is associated with a high incidence of postoperative nausea and vomiting (PONV). A number of approaches are available for the management of PONV after breast cancer surgery. First, the risk factors related to patient characteristics, surgical procedure, anesthetic technique, and postoperative care can be reduced. More specifically, the use of propofol-based anesthesia can reduce the incidence of PONV. Secondly, a wide range of prophylactic antiemetics, including butyrophenones (droperidol), benzamides (metoclopramide), glucocorticoids (dexamethasone), clonidine, a small dose of propofol, and serotonin receptor (SR) antagonists (ondansetron, granisetron, tropisetron, dolasetron, ramosetron, and palonosetron), are available for preventing PONV. Thirdly, antiemetic therapy combined with granisetron and droperidol or dexamethasone, and a multimodal management strategy which includes a package consisting of dexamethasone, total intravenous anesthesia with propofol, and ondansetron are highly effective in preventing PONV. Unfortunately, the use of glucocorticoids and SR antagonists for preventing PONV is not permitted in Japan according to national health insurance guidelines. Fourth, electro-acupoint stimulation at the P6 point (Nei-Guwan) as a non-pharmacologic therapy is as effective as ondansetron for preventing PONV. Knowledge of the risk factors for PONV, antiemetics, and a non-pharmacologic approach are needed for the management of PONV in women undergoing breast cancer surgery.
