Value of fentanyl in flexible sigmoidoscopy.
Studies have recorded significant patient discomfort during flexible sigmoidoscopy when it is performed without sedation/analgesia. This study observed whether a single dose of 50 mcg intravenous fentanyl reduces pain, improving compliance, acceptability, and completion rates. In a prospective study, 109 consecutive patients were offered the option of 50 mcg intravenous fentanyl or no analgesia. Patient's pre-procedure expectations, objective pain scores, and willingness to undergo a subsequent procedure using the same technique were recorded. Endoscopist recorded the success, complications, and objective pain scores for each patient. Of the 46 patients (42%) choosing fentanyl, 9 (20%) experienced moderate/severe pain as against 26 (41%) of the 63 patients (58%) opting for no analgesia (p < 0.05). Further, 52% receiving fentanyl had a significantly better experience compared to their pre-procedure expectations as against 33% who received no analgesia (p < 0.05). No patient receiving fentanyl expressed unwillingness to undergo the procedure again using the same technique, whereas 16 (25%) of those receiving no analgesia indicated they would not (p < 0.01). Endoscopists recorded moderate/severe pain in 13 patients (12%), whereas 35 patients (32%) recorded moderate/severe pain (p < 0.001). Analgesia for endoscopy should involve patient choice. However, a single dose of 50 mcg fentanyl reduced patient discomfort and improved satisfaction. It appeared safe and likely to improve patient compliance and acceptability for flexible sigmoidoscopy.
