2020
Abstract Background Postoperative Nausea and Vomiting (PONV) risk factors have not been defined for obstetric patients. In this study, our objective was to identify potential risk factors for PONV after cesarean sections performed under spinal anesthesia. Methods One cohort of patients submitted to cesarean under spinal anesthesia was used to investigate potential risk factors for PONV. The best numerical risk factors were dichotomized, using chi-squared method. A conditional independence (incremental association method) casual network was used to select the best predictors for PONV. Results Two hundred and fifty of 260 patients remained in the study. Odds ratio for PONV of younger maternal age ( Conclusions Intraoperative nausea and maternal age
