Effect of Fentanyl on Bispectral Index (BIS) Values and Recall

摘要

Fentanyl is given as a premedication for surgery, as a supplement to regional and general anesthesia, as an analgesic for postoperative pain, and sometimes as an anesthetic. The purpose of this study was to describe the effect of IV fentanyl on BIS values and recall. Anesthesia providers often give fentanyl with a sedative to decrease anxiety, pain, ease induction and maintenance of anesthesia. The sedative properties of fentanyl may allow it to be given alone to accomplish the same goals. The study consisted of a convenience sample of twenty adult patients undergoing elective surgery who consented to participate. Fentanyl was titrated to effect in increments of 25-50 mcg every two to five minutes up to a maximum (preoperative) dose of 5 mcg/kg. A picture was then shown and the patient assessed for recall after recovery from anesthesia.
