Objectives: To find out prehospital factors linked with low pain on arrival into a traumatic emergency unit., Methods: A 4-month monocentric prospective study, including patients recruited at their arrival into a traumatic emergency unit. Pain (with a numerical rating scale [NRS]), anxiety, prehospital care including the type of transportation (physician staffed ambulances {service mobile d'urgence et de réanimation [Smur]}, emergency medical technicians, or firemen ambulances), immobilization and analgesics used were evaluated. These data were collected on arrival at the hospital by the ED orientation nurse. Uni- and multivariate analysis were performed to identify low pain's predictive factors (e.g. with a NRS ≤3)., Results: Three hundred and four patients were recruited, mean age=51±25, sex ratio=1.8, mean pain/10=5.8±2.9, 64% with a moderate or severe pain on arrival (NRS>3). For one third of patients, immobilizations hadn't been performed during the prehospital phase. Medical management by Smur is a low pain predictive factor (OR=5.8; CI 95%=1.4-24.16), anxiety is a pejorative factor (OR=0.53 CI 95%=0.38-0.75)., Conclusion: Our study highlights the physician staffed ambulances' effectiveness in prehospital trauma victims' management and raises the question of anxiolysis as an adjuvant for traumatic pain management., (Copyright © 2010 Elsevier Masson SAS.

Results: Three hundred and four patients were recruited, mean age=51±25, sex ratio=1.8, mean pain/10=5.8±2.9, 64% with a moderate or severe pain on arrival (NRS>3). For one third of patients, immobilizations hadn’t been performed during the prehospital phase. Medical management by Smur is a low pain predictive factor (OR=5.8; CI 95%=1.4–24.16), anxiety is a pejorative factor (OR=0.53 CI 95%=0.38–0.75). Conclusion: Our study highlights the physician staffed ambulances’ effectiveness in prehospital trauma victim''s management and raises the question of anxiolysis as an adjuvant for traumatic pain management.
