Study summary

The goal of this clinical trial is to learn if patient administered propofol sedation results in superior patient satisfaction compared to nurse administered propofol sedation in diagnostic colonoscopies.

  • Does self administration of the sedative propofol increase patient satisfaction? Researchers will compare patient administered propofol sedation (where the patient administers propofol by pushing a button) with nurse administered propofol sedation (where a nurse gives the patient bolus doses of propofol as deemed necessary)

Participants will:

  • Be randomized to either sedation route.
  • Answer a preendoscopy questioneere and a postendoscopy questioneere 1 hour after the examination as well as one week after the examination.

Study arms

  • Experimental
    Patient controlled propofol sedation

    Patients will self administer propofol by pushing a button (5 mg iv, 8 activations per minute resulting in max dose of 40 mg propofol/minute) as needed

    Drug: Self administred propofol

  • Active comparator
    Nurse assisted propofol sedation

    The endoscopy nurse will administer propofol in bolus doses of 10 mg iv as needed

    Drug: Nurse assisted propofol sedation

Interventions

  • DrugSelf administred propofol

    Patients will self administer propofol by pushing a button. When pushed a dose of 5 mg propofol will be given intravenously. The button can be pushed a maximum of 8 times per minute.

  • DrugNurse assisted propofol sedation

    The endoscopy nurse will administer bolus dosus of propofol (10 mg iv) as needed during the examination

What researchers measure

Primary outcomes

  1. Patient satisfaction

    Patient satisfaction measured using Patient satisfaction with sedation index (PSSI), a validated Likert-scale questionnaire with 13 questions. Each question with 5 ranks (1-5). Minimum score 13 , maximum score 65. Higher score indicates higher satisfaction with the sedation.

    Time frame: One hour after the examination and one week after the examination

Secondary outcomes

  1. Total propofol dose (mg)

    Total given dose during the examination

    Time frame: 0 hours after examination

  2. Recovery time

    Time to patient is ready for discharge. Patient will be assesed every 15 minutes until ready for discharge, maximum 4 hours

    Time frame: 4 hours after the examination

  3. Procedure duration

    Time to completion of the procedure (min)

    Time frame: 0 hours after examination

  4. Adverse events

    Any adverse events related to sedation within 30 days

    Time frame: 30 days
