Brief Summary:
Based on previous results, the investigators considered that sedation quality, complications, and procedure outcomes may not be different, however, propofol alone titration may have a fast recovery time than BPS and cost-effectiveness than balanced propofol sedation (BPS). In present study, the investigators therefore evaluate the time and sedation quality of patient recovery, cost-effectiveness, complication, and procedure outcomes between propofol alone and BPS in therapeutic endoscopic retrograde cholangiopancreatography (ERCP).

Condition or disease Intervention/treatment Phase
Conscious Sedation Failure During Procedure Drug: Propofol Drug: BPS Phase 4

Detailed Description:
Previous studies have shown that propofol is superior to traditional sedation regimens with benzodiazepines plus opioids in ERCP procedures. Propofol is a potent hypnotic drug with a short duration of action and consequently a more rapid recovery time for the patients compared with the available Benzodiazepines. Several prospective studies have shown that balanced propofol sedation (BPS) can be used safely and effectively for diagnostic endoscopy under the direction of a gastroenterologist. BPS which was originally described by Cohen et al, combines small incremental doses of propofol with single induction doses of benzodiazepines and opioids under the direction of a physician that is not an anesthesiologist. Because BPS usually targets moderate sedation, adequate amnesia and analgesia can be achieved with concomitant administration of benzodiazepines and opioids. It may cause synergism between propofol and midazolam and reduce dose of propofol. However, there was no proven benefit between propofol alone titrated to moderate level of sedation and BPS; propofol titration combination with benzodiazepines and fentanyl.

Drug Information available for: Propofol

Arm Intervention/treatment
Active Comparator: Propofol group
the conventional propofol group (P group), sedation was induced by an intravenous bolus injection of propofol (0.5 mg/kg body weight; 10 mg if age > 70 or ASA class III-IV).
Drug: Propofol
propofol (0.5 mg/kg body weight; 10 mg if age > 70 or ASA class III-IV)
Other Name: A GROUP

Active Comparator: BPS group
the balanced propofol sedation group (BPS group), both midazolam (0.05 mg/kg body weight; 1 mg if age > 70 or ASA class III-IV) and fentanyl (50 µg; 25 µg if age > 70 or ASA class III-IV) were given intravenously at the initiation of sedation. Thereafter, an initial bolus of propofol (0.5 mg/kg body weight) was given intravenously. Sedation was maintained with repeated doses of 10 to 20 mg propofol.
Drug: BPS
midazolam (0.05 mg/kg body weight; 1 mg if age > 70 or ASA class III-IV) fentanyl (50 µg; 25 µg if age > 70 or ASA class III-IV) propofol (0.5 mg/kg body weight)
Other Name: B GROUP

Primary Outcome Measures :
  1. Recovery time and cost-effectiveness [ Time Frame: SIX MONTH ]
    Following therapeutic ERCP,full recovery time scoring by Aldrete scoring system and cost measured.

Secondary Outcome Measures :
  1. Sedation efficacy, procedure-related outcomes, and complications. [ Time Frame: SIX MONTH ]

    Sedation efficacy parameters was defined as follows; Onset of effective sedation, Patient cooperation (endoscopist, observer-nurse), recovery time, and Patient tolerance (rated by the patients 4hr after procedure).

    Quality of procedure was assessed by procedure outcomes and procedure related complications.
