The risk of PONV can be assessed using a scoring system such as Apfel simplified scoring system, which is based on four independent risk predictors with each being given one point. We took this scoring system one step ahead and allocated PONV risk score according to their individual weightage and developed a cumulative risk index. We aimed to identify if the cumulative score of six different predictors in patients undergoing general anesthesia would correlate with the incidence of PONV.The result of this small study based on 24 patients did not show ant correlation between cumulative risk score and actual incidence of PONV. However, we did observe the highest incidence of PONV in patients who were female and had history of PONV. A multimodal approach with combination of pharmacological and non-pharmacological prophylaxis may be advocated in female patients and those having history of PONV undergoing elective surgery under general anesthesia.
