More than 180,000 people die from trauma every year. Bleeding is the major cause of preventable death after trauma. Patients who get blood quickly after severe injuries are less likely to die, revealed researchers from the University of Cincinnati (UC) Department of Emergency Medicine.
The research was published in the April 2016 issue of The Journal of Trauma and Acute Care Surgery. In this study, researchers tracked trauma patients taken from the scene of their injury by Air Care to the University of Cincinnati Medical Center (UCMC) who received at least one unit of blood within 24 hours of arriving at the hospital.
‘Shortening the time to blood transfusion, including having blood available in the prehospital setting, may improve patient outcomes after a trauma.’
Advertisement"Air Care is the only helicopter in the area to carry blood (and plasma), so we had the research platform to study how early blood transfusions impact outcomes," explained Elizabeth Powell, assistant professor of emergency medicine in the UC Department of Medicine and lead author on the study.
Most patients received their first blood transfusion from Air Care or within one hour of getting to UCMC. For these patients, each 10 minute delay in getting blood increased the chance of death.
"Delays in the time to blood transfusion are associated with increased chances of dying," says Powell. "Shortening the time to transfusion, including having blood available in the prehospital setting, may improve outcomes."
Powell says as the result of the research, she does not anticipate a change in ED protocols. "However," she says, "other critical care transport services may need to examine their protocols and consider the use of blood products in their practice." Few critical care transport services currently carry blood products, Powell noted.
