Primary Outcome Measures:
  • Patient satisfaction [ Time Frame: At the end of the procedure, expected average of 30 minutes ]

    Measured with a analog scale from 1 to 4:

    1. Excellent.
    2. Good.
    3. Regular.
    4. No.


Secondary Outcome Measures:
  • Gastroenterologist satisfaction [ Time Frame: At the end of the procedure, expected average of 30 minutes ]

    Measured with a analog scale from 1 to 4:

    1. Excellent.
    2. Good.
    3. Regular.
    4. No.

  • Adverse events [ Time Frame: At the end of the procedure, expected average of 30 minutes ]
    Occurrence of cardiac arrythmias, mild respiratory depression, severe respiratory depression, bradycardia, hypotension, pain, nausea or vomiting, absence of amnesia.


Other Outcome Measures:
  • Level of consciousness [ Time Frame: Every minute until the end of the procedure, expected average of 30 minutes ]
    Ramsay scale.

Arms Assigned Interventions
Active Comparator: Remifentanil

Remifentanil target controlled infusion effect site with Minto's pharmacokinetic model.

Start dose: 1 ng/mL. Titration: 0.5 ng/mL according to clinical criteria.

Drug: Remifentanil
Active Comparator: Propofol

Propofol target controlled infusion effect site with Marsh's pharmacokinetic model.

Start dose: 1 mcg/mL. Titration: 0.5 mcg/mL according to clinical criteria.

Drug: Propofol

Detailed Description:

The administration of sedation with target controlled infusion (TCI) systems could offer a safe alternative for the management of discomfort of patients undergoing endoscopic gastrointestinal procedures. However, what medication from those available for TCI would be the most appropriate is not known.

Sixty-nine patients requiring a gastrointestinal endoscopic procedure were randomly assigned to receive a TCI effect site (e) of remifentanil (n=30) or propofol (n=39). The primary outcome was patient satisfaction. Secondary outcomes included gastroenterologist satisfaction, the proportion of adverse events between the two groups were compared (occurrence of cardiac arrhythmias, mild respiratory depression, major respiratory depression, bradycardia, hypotension, pain, nausea or vomiting, and lack of amnesia), and the level of consciousness.
