Fentanyl for sedation during upper gastrointestinal endoscopy.

The effects of sedation by intravenous fentanyl on the rate-pressure product (pulse rate x systolic blood pressure/100), arterial oxygen saturation, electrocardiographic change, and serum cortisol concentration were studied during gastroduodenoscopy in 84 patients randomized to receive fentanyl or no intravenous sedative (controls). Fentanyl administration increased the tolerance of patients and attenuated the endoscopy-induced rise in rate-pressure product and serum cortisol concentration. Desaturation of arterial oxygen was minimal and there was no difference in arterial oxygen saturation between the fentanyl group and the control group. Therefore, fentanyl appears to be a favorable sedative for upper gastrointestinal endoscopy, since its administration increased the tolerance of patients and decreased cardiac oxygen consumption.[1]
