Uncontrolled hemorrhage and exsanguination are the leading cause of preventable death, and resuscitative therapy is a critical component for survival. In various combinations, fresh whole blood, blood components, colloids, and crystalloids have all been staples of trauma care. The use of fresh whole blood is a well-established military practice that has saved the lives of thousands of American and coalition military personnel. Civilian use of fresh whole blood is far less established owing to the wide availability of individual blood components. However, this highly tailored blood supply is vulnerable to both natural and man-made disasters. In the event of such disruption, such as a major hurricane, it may be necessary for civilian hospitals to rapidly enact a fresh whole blood program. Therefore, the aim of this article is to review the current use of blood therapy for trauma resuscitation, the US military's approach to fresh whole blood, and how maintaining a civilian capacity for fresh whole blood collection in the event of future man-made and natural disasters is key to promoting survival from trauma. (Critical Care Nurse. 2016; 36[3] 1 Hemorrhage, in turn, quickly leads to hypoperfusion, or "shock," and coagulopathy.2 Death due to hemorrhage occurs soon after trauma, usually within the first 6 hours of hospital admission.3,4 US hospital data on trauma patients indicates that coagulopathy, which is associated with early mortality, occurs in 28% of hospital admissions.5 Determining which patients are at risk of shock and coagulopathy developing and applying resuscitation strategies to prevent these processes directly improve survival. 6 In various combinations, fresh whole blood (FWB), blood component therapy (BCT), colloids, and crystalloids have all been staples of trauma care. Therefore, our aim is to review the current use of blood therapy for trauma resuscitation and the US military's approach to FWB. This article has been designated for CE contact hour(s). The evaluation tests your knowledge of the following objectives: 1. Compare and contrast the evidence regarding the transfusion of fresh whole blood 2. Describe the application of fresh whole blood transfusion in the event of a man-made or natural disaster 3. Describe the steps and supplies necessary for the safe collection of fresh whole blood To complete evaluation for CE contact hour(s) for test #C163, visit www.ccnonline.org and click the "CE Articles" button.
