Abstract Objective：To analyze the application and clinical effects of remifentanil with sevoflurane in the controlling hypotension for nasal endoscopic surgery.Method：84 patients who were conducted the nasal endoscopic surgery in our hospital from March 2012 to June 2014 were taken as the research objects，and these patients were randomly divided into control group and observation group，with 42 patients in each group.Then，both of the two groups were adopted the sevoflurane combined intravenous with inhalation anesthesia.Then，in the control group，they were treated with the nitroglycerin while in the observation group，they were treated with the remifentanil.Then，the change of HR in the different periods during the operations and the situations after surgeries of both the two groups were observed.Result：The HR during the hypertension in the observation group was evidently lower than the control group.In addition，the SSFQ score and the intraaoperative blood volume in the observation group were evidently lower than that in the control group and the differences had the statistical significance（ P<0.05）. However，the extubation time did not have evident significances（ P>0.05）.Conclusion：The applications of remifentanil with sevoflurane in the controlling hypotension for nasal endoscopic surgery can effectively improve the bradycardiac，promote the steady blood pressure and decrease the blood volume during the surgeries.Thus，it should be promoted in the clinic applications.
