NCT02486328

Brief Summary

There are different sedation regimes for lower gastrointestinal system endoscopy which can be administered by anesthesiologists and non-anesthesiologists. This study aims to compare the effects of propofol/remifentanil combination and midazolam/meperidine combination on early cognitive function following lower gastrointestinal system endoscopies.

Outcome Measures

Primary Outcomes (2)

  • Change in Cognitive Function

    As measured by Trieger Dot Test. The test does not have an upper limit; the time taken to complete the test is added to the number of dots missed by the patient and a result is obtained. The lowest score possible is 0. Higher values represent worse outcomes.

    Baseline and 5, 15, 30 minutes after the procedure

  • Change in Cognitive Function

    As measured by Digit Symbol Substitution Test. Scale range 0-9. No cut-off value. Higher results represent better outcomes

    Baseline and 5, 15, 30 minutes after the procedure

Secondary Outcomes (4)

  • Change in Visual Analogue Scale Scores From the Baseline

    Baseline and 5, 15, 30 minutes after the procedure

  • Heart Rate

    Baseline and 1,2,3,5,10,15 and 20 minutes

  • Mean Arterial Pressure

    Baseline and 1,2,3,5,10,15 and 20 minutes

  • Peripheral Oxygen Saturation

    Baseline and 1,2,3,5,10,15 and 20 minutes

Study Arms (2)

Group MM

OTHER

2 mg midazolam and 20mg meperidine given intravenously and additional 1-2mg midazolam and 20mg meperidine (wtih a maximum total of 5 mg midazolam and 50 mg meperidine) given when FPS greater than 3

Drug: MidazolamDrug: Meperidine

Group RP

OTHER

100 mcg/kg/min propofol infusion and 1 mcg/kg remifentanil bolus administered and additional 0,5 mcg/kg remifentanil bolus given when FPS greater than 3

Drug: RemifentanilDrug: Propofol
