FIC increases the intrathoracic pressure and risks of postoper- ative nausea and vomiting, yet available treatments are limited. This study was designed to investigate whether ad- ministering fentanyl via a slow intravenous fluid line can effectively alleviate FIC during induction of total intravenous general anesthesia. Methods： A total number of 1200 patients, aged 18-64 years, were enrolled, all of whom were American Society of Anesthesiologists （ASh,） grade I or II undergoing scheduled surgeries. All patients received total intravenous general anesthesia, which was induced sequentially by midazolam, fentanyl, propofol, and cisatracurium injection. Patients were randomly assigned to receive fentanyl 3.5 pg/kg via direct injection （control group） or via a slow intravenous fluid line. FIC incidence and the severity grades were analyzed with the Mann-Whitney test. Other adverse reactions, such as hypotension, hypertension, bradycardia, tachycardia, hypoxemia, vomiting, and aspiration, during induction were also observed. The online clinical registration number of this study was ChiCTR-IOR-16009025. Re- sults： Compared with the control group, the incidence of FIC was significantly lower in the slow intravenous fluid line group during induction （9.1%, 95% confidence interval （CI）： 6.7%-11.4% vs. 55.9%, 95% CI： 51.8%-60.0%, P=0.000）, as were the severity grades （P=0.000）. There were no statistical differences between the two groups with regard to other adverse reactions （P〉0.05）. Conclusions： The administration of fentanyl via a slow intravenous fluid line can alleviate FIC and its severity during induction for total intravenous general anesthesia. This method is simple, safe, and reliable, and deserves clinical expansion.展开更多
