Further study details as provided by Minneapolis Medical Research Foundation:

Primary Outcome Measures:
  • Respiratory Depression (Sub-clinical and Clinical Signs) [ Time Frame: From one minute prior to start of the procedure until the patient has returned to baseline mental status after the conclusion of the sedation procedure up to 60 minutes) ]
    binary measure based on the occurrence of an oxygen saturation less than 93 at any time, a change in baseline end tidal co2 >10 or an absence on capnographic waveform

Secondary Outcome Measures:
  • Time to Return of Baseline Mental Status [ Time Frame: from start of procedure until the return of baseline mental status up to 120 minutes ]
    time in seconds from the first dose of medication until the patient has regained baseline mental status

  • Patient Reported Pain or Recall of the Procedure [ Time Frame: single measurement immediately after patient returns to baseline mental status after sedation procedure ]
    patient completed question after return to baseline mental status "did you feel pain during the procedure" and "do you remember any part of the procedure" answered by circling yes or no on a question sheet, positive if yes to either question

  • Depth of Sedation [ Time Frame: single measurement during sedation procedure ]
    Observes assesment of alertness scale, 1-5 ordinal scale measuring level of awareness, one represents awake, 5 general anesthesia/unresponsive to pain
