Could bystander first-aid prevent trauma deaths at the scene of injury?

Abstract

Objective: To identify potentially preventable prehospital deaths following traumatic cardiac arrest.

Methods: Deaths following prehospital traumatic cardiac arrest during 2003 were reviewed in the state of Victoria, Australia. Possible survival with optimal bystander first-aid and shorter ambulance response times were identified. Injury Severity Scores (ISS) were calculated. Victims with an ISS <50 and signs of life were reviewed for potentially preventable factors contributing to death including signs of airway obstruction, excessive bleeding and/or delayed ambulance response times.

Results: We reviewed 112 cases that had full ambulance care records, hospital records and autopsy details in Victoria 2003. Most deaths involved road trauma and 55 victims had an ISS <50. Twelve patients received first-aid from bystanders. Ambulance response times >10 min might have contributed to five deaths with an ISS <25.

Conclusion: Five (4.5%) potentially preventable prehospital trauma deaths were identified. Three deaths potentially involved airway obstruction and two involved excessive bleeding. There is a case for increased awareness of the need for bystander first-aid at scene following major trauma.
