It affects 20–30% of all post-operative and 70%-80% of higher-risk patients. Consequently, it is one of the most frequently observed adverse events associated with the provision of anesthesia. Thus, this study is aimed to assess the incidence and associated factors of postoperative nausea and vomiting. Methods This cross-sectional study was conducted using a consecutive sampling method. Regular supervision and follow-up were made. Data was entered into Epi info version 7 software and transported to SPSS version 20 for analysis. The odd ratio and 95% confidence interval were computed. The findings of the study were reported using tables, figures, and narration. Variables that were found to be a candidate (p-value < 0.25) on binary logistic regression were entered into a multiple logistic regression analysis to identify independent predictors of postoperative nausea and vomiting.

Research paper thumbnail of Incidence of postoperative nausea and vomiting after paediatric strabismus surgery with sevoflurane or remifentanil–sevoflurane

In this prospective, randomized, double-blind study, we evaluated and compared the incidence of postoperative nausea and vomiting (PONV) after paediatric strabismus surgery with two different anaesthetic methods, sevoflurane or remifentanil-sevoflurane. Methods. In total, 78 paediatric patients (aged 6-11 yr) undergoing strabismus surgery were enrolled and randomly assigned to two groups, sevoflurane (Group S) and remifentanilsevoflurane (Group R). Anaesthesia was maintained with 2-3% sevoflurane in Group S (n¼39) or with a continuous infusion of remifentanil combined with 1% sevoflurane in Group R (n¼39), both using 50% N 2 O/O 2. Arterial pressure and heart rate before induction, after tracheal intubation, after skin incision, and at the end of surgery were recorded. The incidence of PONV in the post-anaesthesia care unit, the day surgery care unit, and at home 24 h after surgery was recorded. Results. Arterial pressure and heart rate were stable throughout the surgery, but were significantly lower in Group R than in Group S after tracheal intubation and skin incision. The incidence of PONV and postoperative vomiting was 17.9%/17.9% and 12.8%/10.2% (Group S/ Group R) at the respective time points; values were comparable between the groups. Conclusions. The incidence of PONV after paediatric strabismus surgery under sevoflurane anaesthesia was relatively low, and combining remifentanil with sevoflurane did not further increase the incidence.
