BackgroundPostoperative nausea and vomiting (PONV) is one of the common complications in patients who have undergone surgery with general anesthesia. The association of intraoperative use of remifentanil with PONV has remained controversial. The aim of the current study was to determine the association of dose of intraoperative remifentanil administration with incidence of PONV.MethodsThe present study was a single-center retrospective observational study and included 423 female patients with American Society of Anesthesiologists physical status I or II who underwent elective mastectomy under general anesthesia between October 2011 and October 2012. The incidence of PONV within 3 days after the operation was prospectively assessed. The time-weighted average of remifentanil during the operation (twRem) was calculated. We used a multivariate regression model to assess the independent association of the twRem with the incidence of PONV.ResultsAmong 423 patients, 129 patients (30.5%) had PONV during the study period. Remifentanil was administrated in 355 patients (83.9%). In the multivariate logistic regression model using categories of twRem, we found that increased twRem was independently associated with increase in the risk of PONV (P=.01). There was an independent association between twRem greater than 0.2 μg/kg per minute and increase in the risk of PONV.ConclusionThis retrospective observational study revealed a dose-dependent association between dose of intraoperative remifentanil administration and increase in the risk of PONV. Time-weighted average of remifentanil greater than 0.2 μg/kg per minute was independently associated with risk of PONV.Copyright © 2016 Elsevier Inc. All rights reserved.
