---|---|
Experimental: Patient-Specific Protocol
Patients assigned to this treatment protocol will be given pain medicine(s) based on the pain medicine(s) they take at home, what was needed during their past hospital and emergency department visits to treat pain and doses that have been effective and safe in the past.
|
Other: Patient-Specific Protocol
Patients assigned to this treatment protocol will be given pain medicine(s) based on the pain medicine(s) they take at home for pain and what was needed during their past hospital and emergency department visits to treat pain. Medicines will include opioids, either morphine or hydromorphone. A member of the outpatient SCD provider team will review the patient's medical record to determine: 1) the patient's maximum home opioid dose, and 2) previous ED analgesic medication(s) and doses that have been effective and safe in the past. The patient's regular hematologist/sickle cell team will write the treatment plans. Medications will be given every 20-30 minutes for up to 6 hours. Drug: Morphine 4 mg for participants weighing <50 kgs, 6mg for participants weighing 50-69.9 kgs, 8mg for participants weighing 70 - 89.9 kgs and 10mg for participants weighing greater than or equal to 90 kgs. dose is given. Re-dosing is every 20-30 minutes up to 6 hours with one possible dose escalation of 25%.
Other Name: Morphine Sulfate Drug: Hydromorphone 1 mg for participants weighing <60 kgs, 1.5 mg for participants weighing 60 - 89.9 kgs, and 2 mg for participants weighing greater than or equal to 90 kgs. dose is given. Re-dosing is every 20-30 minutes up to 6 hours with one possible dose escalation of 25%.

Experimental: Weight-based Protocol
Patients assigned to this treatment protocol will be given pain medicine(s) based on their weight.

Other: Weight-based Protocol
Patients assigned to this treatment protocol will be given pain medicine(s) based on their weight. Medicines will include opioids, either morphine or hydromorphone. Plans will be written by the patients regular hematologist/sickle cell team. Drug: Morphine 4 mg for participants weighing <50 kgs, 6mg for participants weighing 50-69.9 kgs, 8mg for participants weighing 70 - 89.9 kgs and 10mg for participants weighing greater than or equal to 90 kgs. dose is given. Re-dosing is every 20-30 minutes up to 6 hours with one possible dose escalation of 25%.
Other Name: Morphine Sulfate Drug: Hydromorphone 1 mg for participants weighing <60 kgs, 1.5 mg for participants weighing 60 - 89.9 kgs, and 2 mg for participants weighing greater than or equal to 90 kgs. dose is given. Re-dosing is every 20-30 minutes up to 6 hours with one possible dose escalation of 25%.

- Change in pain scores as measured by patient reported pain level. [ Time Frame: baseline (hospital admission), up to 6 hours (hospital discharge) ]Pain is measured by having the patient mark pain on a scale of 0 to 100, with 0 being no pain and 100 being the worst pain ever.
- Average length of study in the emergency department [ Time Frame: Up to 6 hours ]
- Number of return ED visits within the next 7 days [ Time Frame: up to 7 days ]
- Number of hospitalizations for Vaso- Occlusive Episode (VOE) within the next 7 days [ Time Frame: Up to 7 days ]
