Evidence-based prophylaxis strategies for postoperative nausea and vomiting when considering ethnicity factor

Abstract

In most western countries, postoperative nausea and vomiting (PONV) is an important issue and prophylaxis guideline for PONV will be followed in clinical practice. We tried to conduct a review study and a local study to elucidate the incidence and severity of PONV to see if considering ethnicity factor, should we still need to follow those prophylaxis guidelines from western countries. The PubMed, and MEDLINE were consulted from January 2000 to 2018 and also Cochrane Central Register of Controlled Trials (CENTRAL 2010). The key word for searching is PONV (incidence, severity and prevention strategy), without language limitation and focus on Asian countries. The results showed that the overall incidence and severity of PONV in Asian countries was less significant than in western countries. PONV in western countries could be a serious issue and prophylaxis strategy adjusted by Apfel score could be adopted in routine practice. After this review consultation, the issue of PONV in different ethnic countries (including Taiwan) might be over emphasized and we may suggest not to follow west countries PONV prophylaxis guideline as our routine practice.
