Primary Outcome Measures:
  • Number of Participants With Sub-clinical Respiratory Depression and Clinical Events Associated With Respiratory Depression During the Sedation Procedure [ Time Frame: From one minute prior to start of procedure until the patient has returned to baseline mental status after the conclusion of the sedation procedure (~3-60 minutes depending on procedure duration) ]

Secondary Outcome Measures:
  • Time to Return of Baseline Mental Status From Start of Procedure in Minutes [ Time Frame: Single time point after completion of sedation procedure, measured from start of procedure until the patient returns to baseline mental status up to 24 hours ]
  • Depth of Sedation Measured Using the OAAS Scale [ Time Frame: Single measurement during sedation procedure ]
    Observers Assesment of Alertness Scale, 5 responds normally to voice, 4 lethargic response to voice, 3 responds only to loud voice or light touch, 2 responds only to mild prodding or shaking, 1 responds only to painful stimuli, 0 no response to painful stimuli

  • Patient Reported Pain [ Time Frame: Single measurement immediately after patient returns to baseline mental status after sedation procedure ]
  • Patient Reported Recall of the Procedure [ Time Frame: Single measurement immediately after patient returns to baseline mental status after sedation procedure ]

Enrollment: 126
Study Start Date: October 2009
Study Completion Date: April 2015
Primary Completion Date: April 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Propofol
Propofol 1m g/kg IV followed by 0.5 mg/kg IV prn sedation
Drug: Propofol
Propofol 1 mg/kg IV followed by 0.5 mg/kg prn sedation
Active Comparator: Alfentanil
Sedation using alfentanil 10 ug/kg followed by 5 ug/kg prn sedation
Drug: Alfentanil
Alfentanil 10 ug/kg IV followed by 5 ug/kg prn sedation

Detailed Description:
This was initially going to be a trial of propofol vs alfentanil vs nitrous oxide, but our use of nitrous oxide was discontinued before the trial began and the trial was conducted with only two arms
