  Purpose

This will be a randomized controlled trial that compares the rates of sedation related complications in high risk patients (ASA greater or equal to 3, BMI greater or equal to 30, those at risk for OSA) undergoing advanced endoscopy procedures with propofol alone compared to propofol in combination with benzodiazepines and opioids.

Primary Outcome Measures:
  • Frequency of airway maneuvers [ Time Frame: one day (during procedure) ] [ Designated as safety issue: No ]
    In high risk patients (meeting at least of 1 of 3 criteria: ASA ≥ 3, BMI ≥ 30, those at risk for OSA) undergoing advanced endoscopy procedures, compare the frequency of AMs when sedated with propofol alone versus propofol in combination with benzodiazepines and opioids.


Secondary Outcome Measures:
  • Frequency of other sedation related complications [ Time Frame: one day (during procedure) ] [ Designated as safety issue: No ]
    We will compare the frequency of other sedation related complications such as hypotension, hypoxemia and need for termination of the procedure between the two groups

  • Compare propofol doses between the two groups [ Time Frame: one day (during procedure) ] [ Designated as safety issue: No ]
    The dose of propofol used between the two groups will be compared

  • Predictors of sedation related complications [ Time Frame: one year ] [ Designated as safety issue: No ]
  • Patient tolerance as assessed by the patient, endoscopist and CRNAs will be compared between the two groups [ Time Frame: 24-48 hours ] [ Designated as safety issue: No ]
    The frequency of symptoms of nausea and vomiting in the two groups of patients will be recorded. Patient tolerance of the procedure will be assessed independently by the endoscopist and CRNA using a 100-mm visual analog scale (VAS, 0=unmanageable, 100=excellent). The patient will also score the level of tolerance using the same VAS at a routine follow-up phone call made 24-48 hours after the procedure.

  • Frequency of symptoms of nausea and vomiting will be compared between the two groups [ Time Frame: 24-48 hours ] [ Designated as safety issue: No ]
    The frequency of symptoms of nausea and vomiting in the two groups of patients will be recorded. This will be recorded during the follow-up phone call made 24-48 hours after the procedure.

Arms Assigned Interventions
Active Comparator: Propofol+Benzo/Opioids

If the patient is randomized into this arm the recommended Versed and Fentanyl doses are standardized:

  1. Recommended Versed:

    a. Prior to intubation

    • patient is < 50 kg = 1 mg Versed
    • patient is 50-75 kg = 1.5 mg Versed
    • patient is > 75 kg = 2 mg Versed
  2. Recommended Fentanyl

    1. Prior to intubation = 0.5 ug/kg
    2. Total procedural dose = 1 ug/kg
Drug: Propofol+Benzo/Opioids
  1. Recommended Versed:

    a. Prior to intubation

    • patient is < 50 kg = 1 mg Versed
    • patient is 50-75 kg = 1.5 mg Versed
    • patient is > 75 kg = 2 mg Versed
  2. Recommended Fentanyl

    1. Prior to intubation = 0.5 ug/kg
    2. Total procedural dose = 1 ug/kg
Other Names:
  • Benzodiazepine
  • Midazolam
  • Versed
  • Opioid
  • Fentanyl
Active Comparator: Propofol Alone

The patients randomized into the sedation with propofol alone are able to cross over if they are unable to be successfully sedated under propofol alone. The the recommended doses before considering crossover are standardized:

  • Induction Dose: 2-2.5 mg/kg
  • Maintenance Dose: 0.1-0.2 mg/kg/min
Drug: Propofol Alone

Recommended Propofol doses before considering crossover:

  • Induction: 2-2.5 mg/kg
  • Maintenance: 0.1-0.2 mg/kg/min
Other Names:
  • Propofol
  • Diprivan
  • 2,6-di-isopropofol
