Randomized Controlled Trial Multicenter Study
Nitrous oxide for early analgesia in the emergency setting: a randomized, double-blind multicenter prehospital trial.
Although 50% nitrous oxide (N(2) O) and oxygen is a widely used treatment, its efficacy had never been evaluated in the prehospital setting. The objective of this study was to demonstrate the efficacy of premixed N(2) O and oxygen in patients with out-of-hospital moderate traumatic acute pain. ⋯ This study demonstrates the efficacy of N(2) O for the treatment of pain from acute trauma in adults in the prehospital setting.
