Postoperative nausea and vomiting (PONV) is a common complication after aesthesia, which may cause dehydration, electrolyte imbalance and even aspiration. Although anesthesia technology has made great progress, the incidence of PONV is still high. Non-pharmacological intervention is an important way to manage PONV, but it has not attracted enough attention. This paper reviews the adverse effects, risk prediction and severity assessment tools of PONV, and non-drug intervention methods, so that nurses can better understand the management status of PONV, and then provide reference for improving the management strategy of PONV.
