Comparing pain relief methods for children with limb injuries in emergency departments

Pain Reduction for Limb Injuries in Pediatric Emergency Departments: A Randomised Clinical Trial Comparing Intranasal Fentanyl or Intranasal Ketamine to Oral Morphine

PHASE3 · Assistance Publique - Hôpitaux de Paris · NCT06464146

This study is testing whether using nose sprays of fentanyl or ketamine can help relieve pain faster and better than oral morphine for kids aged 2 to 17 with limb injuries in emergency rooms.

What this trial studies

This study aims to evaluate the effectiveness of intranasal fentanyl and intranasal ketamine compared to oral morphine in reducing moderate to severe pain in children aged 2 to 17 years with limb injuries. The research focuses on children presenting to emergency departments within 12 hours of their injury, using a pain assessment scale to measure outcomes at 30 minutes post-administration. The study seeks to determine if the non-invasive intranasal route provides faster and more effective pain relief than traditional oral morphine. This approach could potentially improve pain management strategies in pediatric emergency care.

Who should consider this trial

Good fit: Ideal candidates are children aged 2 to 17 years with moderate to severe pain from limb injuries presenting to the emergency department.

Not a fit: Patients who have received narcotic pain medication prior to arrival or have contraindications to the study medications may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective and rapid pain relief options for children with limb injuries in emergency settings.

How similar studies have performed: While there are no existing studies comparing intranasal fentanyl or ketamine to oral morphine in this specific context, the use of intranasal analgesics has shown promise in other settings.
