Routine droperidol pre-medication improves sedation for ERCP.
BACKGROUND
Pre-medication with droperidol has been used to improve sedation during endoscopy, especially in patients with a history of alcohol or narcotic abuse. We studied whether routine use of droperidol pre-endoscopic retrograde cholangiopancreatography (ERCP) could improve patient and physician satisfaction with sedation.


METHODS
Sixty-seven patients undergoing routine ERCP were enrolled in this double-blind placebo-controlled study. Patients were given either parenteral normal saline solution or 5 mg of droperidol 15 minutes before the procedure. After the ERCP, several parameters of procedural sedation were scored on an ordinal scale by the endoscopist, the endoscopy nurse, and the recovered patient. In addition, a follow-up telephone call was made to the patient after 24 hours.


RESULTS
The mean procedural room time was similar in the two groups. Nearly 25% less meperidine and diazepam was used in the droperidol-treated patients, making the overall medication cost similar in both groups. The mean recovery room time was 113 minutes for the placebo group and 106 minutes for the droperidol group. Droperidol premedication significantly decreased post-procedure nausea and vomiting, reduced gagging at intubation, and decreased retching during the procedure. Droperidol also improved physician (p = 0.001), nurse (p = 0.001), and patient (p = 0.0001) impressions of overall sedation and decreased the need for physical restraint during the procedure. Droperidol significantly increased the number of patients with no memory of the procedure.


CONCLUSIONS
Droperidol improved overall patient, physician, and nurse satisfaction with sedation during ERCP. It also reduced post-ERCP nausea and vomiting without increasing recovery time or medication cost. Droperidol is recommended for routine pre-ERCP sedation. (Gastrointest Endosc 2000;52:362-6).
