E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to illustrate the comparative efficacy of intranasal fentanyl to IV morphine in reducing severe pain associated with Painful Sickle Cell Crises in the Emergency Department. |
|

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint of this study is the measurement of difference in pain score reduction between study arms, on age-appropriate numeric pain rating scales, measured 10 minutes after administration of study medication. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
10 minutes after administration of study medication. |
|
E.5.2 | Secondary end point(s) |
The secondary endpoints of this study include: Measurement of time to analgesic effect as defined by time to reduction in pain from severe (7-10) to: o Moderate o Mild and o No pain Measurement of the need for rescue analgesia, defined as exacerbation of pain requiring supplemental analgesia; Measurement of other secondary effects, including: o Nausea and vomiting o Measurement of respiratory depression, as defined by an age appropriate self-ventilation rate that fails to provide full ventilation and perfusion of the lungs o Measurement of cardiovascular depression, as defined as heart rate and/or blood pressure falling below age appropriate rates in the absence of any other aetiology o Measurement of sedation level using the University of Michigan Sedation Score
|
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
The secondary endpoints will be assessed over the 120 minute study period. Pain scores will be performed at 0, 5, 10, 15, 20, 30, 60 and 120 minutes after the administration of study drug. The trial will cease at 120 minutes after the administration of study drugs. |
