Plain English Summary
Background and study aims
Sickle cell anaemia is an inherited blood disorder which results in abnormal ‘sickle’ shaped red blood cells which do not fit well through small blood vessels, becoming trapped and forming blockages. Blockages prevent oxygen in the blood from reaching different parts of the body, resulting in pain. These painful crises occur commonly in children. These crises are unpredictable, affecting any area of the body, although the chest, tummy, and bones are frequently affected sites. Crises may be separated by more than a year or possibly only by weeks, and they can last from hours to weeks. Pain relief is first achieved with paracetamol or ibuprofen for milder painful episodes, but many may need stronger pain relief in the Emergency Department. Stronger pain relief may be achieved by oral medicine (codeine/morphine) and drip medicine (intravenous morphine) for moderate to severe episodes of pain. Fentanyl (another type of strong pain relief), delivered via the nose as a spray (intranasal), has been shown to be as safe and as good as morphine (via a drip) in children with broken bones or tummy pain, with the benefit of quicker time to start acting, as it does not rely on the placement of a drip. The procedure of receiving intranasal fentanyl is also less distressful for the child than a drip. The aim of this study is to assess the effect of intranasal fentanyl in painful sickle cell crisis to see whether it is as good as strong pain relief via a drip.
Who can participate?
Patients aged 1 to 21 with severe pain due to sickle cell disease
What does the study involve?
Participants are randomly allocated to be treated with either intranasal fentanyl or intravenous morphine. Pain, time to analgesic (pain relief) effect, need for more pain relief, side effects such as nausea and vomiting, breathing, heart rate and blood pressure are measured in both groups.
What are the possible benefits and risks of participating?

Study information
Scientific title

Acronym
Study hypothesis
Those patients with severe painful sickle cell crisis receiving intransala (IN) fentanyl will achieve similar pain relief to those who receive intravenous (IV) morphine.

Drug names
Fenatanyl, morphine
Primary outcome measures
Pain measured on an appropriate numeric pain rating scale, 10 minutes after administration of study medication
Secondary outcome measures
1. Time to analgesic effect: Defined as time to reduction in pain from severe to moderate/mild/no pain (pain score 0-6/10)
2. Need for rescue analgesia: defined as exacerbation of pain requiring supplemental analgesia as per the Our Ladys Childrens Hospital, Crumlin (OLCHC) clinical practice guideline
3. Other secondary effects, including:
3.1. Nausea and vomiting
3.2. Respiratory depression, defined as age-appropriate self-ventilation rate that fails to provide full ventilation and perfusion of the lungs (an oxygen saturation below 95% is deemed significant in the absence of any other aetiology other than trial medications (patients with evidence of chest involvement or chest crisis will be excluded)
3.3. Cardiovascular depression, defined as heart rate and/or blood pressure falling below age-appropriate rates in the absence of any other aetiology
3.4. Sedation level, measured using the University of Michigan Sedation Score, a 5-point scale establishing the child's level of arousal
