Brief Summary

This is a randomized, double-blinded, prospective study which will be conducted at the Department of Gastroenterology, King Saud Hospital, Unaizah, Qassim, Saudi Arabia.

Outcome Measures

Primary Outcomes (3)

  • Degree of sedation

    The degree of sedation shows the depth of sedation. It will be measured by the Observer's assessment of alertness/sedation scale with a minimum and maximum value of 1 and 5 reflecting depth of sedation. Where score 1 means deeply sedated while score 5 means fully awake. Higher scores means not enough sedation.

    every 3 minutes till the end of procedure

  • Onset of sedation

    Onset of sedation means how rapidly patient is sedated after giving the sedative medication. if after 20 minutes, patient not sedated then it will be considered failed to sedate.

    It will be measured every 1 minute till 20 minutes.

  • Adverse events and complication

    Adverse events are any unintended or undesirable clinical occurrences that arise during or after a medical procedure, treatment, or intervention. These events may be related to the procedure itself, the medications administered. These may include hypotension, bradycardia, tachycardia, hypoxia, oversedation leading to respiratory suppression

    Monitored continuously during procedure and post procedure for 2 hours and then up to 48 hours after discharge on telephone

Secondary Outcomes (2)

  • Patient's satisfaction with the procedure

    2 hours from the start of the procedure.

  • procedure completion rate

    Decision for procedure completion successfully or not will be at 1 hour. Procedure completion rate at 6 months

Maximum dose: 100 ug

Drug: MidazolamDrug: Fentanyl

Propofol

EXPERIMENTAL

Propofol Before start of colonoscopy procedure patient will be sedated with propofol in this group. Dose:induction dose of 20-50 mg followed by intermittent boluses of 10-20 mg according to the patient response. Maximum total dose of 200 mg. Till completion of the colonoscopy

Drug: Propofol

Propofol +Fentanyl
