Prophylactic antiemetics in oral and maxillofacial surgery: a requiem?--a response.

摘要

I wish to raise a few concerns regarding the article, "Prophylactic antiemetics in oral and maxillofacial surgery: A requiem?," published in September 2009. Extensive, wcll-conducted research has been done with regard to the incidence, causes, prophylaxis, and treatment of postoperative nausea and vomiting (PONV). Patient and anesthetic risk factors have been consistently identified as predictors of PQNV, whereas surgery type has a poor relation to PONV.Due to the confounding effect and distribution of these risk factors, guidelines have been published suggesting how to conduct and present research related to PONV. The use of a PONV predictive score and the administration of antiemetic prophylaxis and treatment of patients experiencing events would be deemed the minimum in any study examining PONV.
