CTIS Part I — objectives, methods, condition coding
Main objective
Scope: Therapy
To compare the analgesic rapidity and efficiency of inhaled Methoxyflurane to oral administration of opioid analgesics, such as Oral Oxycodone Hydrochloride (OxynormORO®) or Morphine Sulfate (Actiskenan®) as initial analgesic in SCD patients visiting emergency department for VOC.
Secondary objectives 6
- Comparison of the patient's satisfaction between the two groups
- Comparison of the nurse's satisfaction between the two groups
- Comparison of the consumption of morphine and analgesics (Nefopam, Paracetamol, and Tramadol) until emergency discharge between the two groups.
- Comparison of the duration of hospitalization between the two groups
- Comparison of the total cost of both devices used in the study (Penthrox® and oral administration of opioid analgesics, such as Oral Oxycodone Hydrochloride (OxynormORO®) or Morphine Sulfate (Actiskenan®)
- Comparison of the occurrence of respiratory (occurrence of infection, acute chest syndrome), neurologic (occurrence of stroke), renal (occurrence of kidney failure) and hepatic (occurrence of Intrahepatic cholestasis or Cholelithiasis) events

Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- The mean pain intensity measured by VAS (Visual Analogic Scale) every 10 minutes during the first hour after admission in the emergency department
Secondary endpoints 9
- Patient's satisfaction measured at the 60th minute by Likert scale ranging from 1 to 10.
- Global ED nurse's satisfaction measured within the first 8h by Likert scale ranging from 1 to 10.
- Total amount (in milligram) of intravenous morphine and analgesics (Nefopam, Paracetamol, and Tramadol) administered until emergency discharge
- Duration of stay (in days) from arrival to emergency department to the end of hospitalization.
- Calculation of the cost of Penthrox® (number of bottles used)
- Calculation of the cost of oral administration of opioid analgesics (number of pills used), such as Oral Oxycodone Hydrochloride (OxynormORO®) or Morphine Sulfate (Actiskenan® )
- Incidence of renal and liver events based on the difference of kidney and liver function between the time of emergency admission and the third to seventh day of hospitalization (if several values are available, the worse value is retained)
- Incidence of acute chest syndrome during hospitalization
- Incidence of neurologic events such as ischemic stroke
