Input: No immediate mortality was reported. There was no significant difference in serious cardio-respiratory complications suffered by patients in either sedation group. Failure to complete the procedure due to sedation-related problems was reported in one study. Three studies found faster and better recovery in patients receiving propofol for their ERCP procedures. Study protocols regarding use of supplemental oxygen, intravenous fluid administration and capnography monitoring varied considerably. The studies showed either moderate or high risk of bias. Results from individual studies suggested that patients have a better recovery profile after propofol sedation for ERCP procedures than after midazolam and meperidine sedation. As there was no difference between the two sedation techniques as regards safety, propofol sedation is probably preferred for patients undergoing ERCP procedures. However, in all of the studies that were identified only non-anaesthesia personnel were involved in administering the sedation. It would be helpful if further research was conducted where anaesthesia personnel were involved in the administration of sedation for ERCP procedures. This would clarify the extent to which anaesthesia personnel should be involved in the administration of propofol sedation.
Output:

There was no significant difference between the sedation techniques as regards safety. There were no deaths in the trials and the number of major complications, such as lack of oxygen (hypoxaemia) and low blood pressure (hypotension), was comparable in both techniques. There was no difference in patient satisfaction in either group. However, the recovery of patients who received propofol was significantly better than for those who had received midazolam and meperidine for the procedure. In conclusion, patients undergoing ERCP procedures under propofol sedation recover faster and better than those patients receiving midazolam and meperidine sedation. This would make propofol the preferred choice for these procedures as there was no difference in the safety of either technique. Further research should focus on the safety of the sedative techniques and involve anaesthesia personnel in the administration of the sedation.
