This clinical trial is focused on studying treatments for acute traumatic pain, which is a sudden and severe pain resulting from an injury. The study will compare the effectiveness of different medications in managing this type of pain. The medications being tested include fentanyl and esketamine, both of which are known for their pain-relieving properties. Fentanyl will be administered either through the nose (intranasal) or directly into the bloodstream (intravenous), while esketamine will be given either through the nose or intravenously. Additionally, a placebo may be used for comparison.
The purpose of the study is to determine if intranasal fentanyl, intravenous esketamine, and intranasal esketamine are as effective as intravenous fentanyl in providing pain relief in a prehospital setting, such as in an ambulance. Participants in the study will receive one of these treatments, and their pain levels will be monitored at various intervals, including 10 and 20 minutes after receiving the medication, as well as upon arrival at the hospital. The study will also assess the need for additional doses and any side effects experienced by participants.
This trial aims to improve pain management for individuals experiencing acute traumatic pain before they reach the hospital. By comparing these treatments, the study hopes to find the most effective and safe option for pain relief in emergency situations. The trial is expected to conclude by March 2025, with recruitment having started in September 2023.
