Background: Prehospital hemorrhagic shock accounts for approximately 25,000 civilian deaths annually in the United States. A balanced, blood-based resuscitation strategy is hypothesized to be the optimal treatment for these patients. Due to logistical constraints, delivering a balanced, blood-based resuscitation is difficult in the prehospital setting. A low titer O+ whole blood (LTO+ WB) ground ambulance initiative, may help alleviate this capability gap.Case Report: A 37-year-old female was involved in a motor vehicle collision at approximately 16:30. While she was trapped inside the vehicle, her mental status deteriorated. The patient was successfully extricated at 17:04 and found to be in cardiac arrest. The paramedics and firefighters quickly secured her airway and applied a mechanical CPR device. The first responder team obtained return of spontaneous circulation, but the patient's blood pressure was 43/27 mmHg. The paramedics transfused one unit of LTO+ WB. Twenty-one minutes after the initial LTO+ WB transfusion, the air ambulance team transfused a second unit of LTO+ WB. Upon hospital arrival, the transfusion was completed, and the patient's shock index improved to 1.0. The trauma team identified a grade 5 splenic injury with active extravasation. Interventional radiology performed an angiogram and successfully embolized the tertiary branches of the inferior splenic pole. She was extubated on postinjury Day one and discharged to her home neurologically intact on postinjury Day 12.Conclusion: The prehospital availability of LTO+ WB may enhance the resuscitation of critically ill trauma patients.

Background Prehospital management of the traumatically injured patient has evolved significantly since the organization of emergency medical services across the United States in the 1970s. Initially focusing on the utilization of crystalloid solutions to restore shed blood volume, robust military and civilian trauma experiences led to a modern day shift towards balanced blood component and ultimately whole blood use for immediate volume replacement. In addition, prehospital transfusion or remote damage control resuscitation (RDRC) has been widely adopted. This has led to point of injury resuscitation using blood products both in the United States and abroad. Objectives This article will review the evolution of civilian and military prehospital resuscitation as well as the current practice of prehospital whole blood transfusion in the civilian trauma population in the United States. Additionally, we will provide an overview of our regional trauma system’s use of whole blood with focus on the programme infrastructure, donor programme, product rotation schedule and logistical challenges. Finally, we provide three case report examples of the effective use of whole blood in our civilian emergency medical services (EMS) programs. [ABSTRACT FROM AUTHOR]

Background: Despite countless advancements in trauma care a survivability gap still exists in the prehospital setting. Military studies clearly identify hemorrhage as the leading cause of potentially survivable prehospital death. Shifting resuscitation from the hospital to the point of injury has shown great promise in decreasing mortality among the severely injured.Materials and Methods: Our regional trauma network (Southwest Texas Regional Advisory Council) developed and implemented a multiphased approach toward facilitating remote damage control resuscitation. This approach required placing low-titer O+ whole blood (LTO+ WB) at helicopter emergency medical service bases, transitioning hospital-based trauma resuscitation from component therapy to the use of whole blood, modifying select ground-based units to carry and administer whole blood at the scene of an accident, and altering the practices of our blood bank to support our new initiative. In addition, we had to provide information and training to an entire large urban emergency medical system regarding changes in policy.Results: Through a thorough, structured program we were able to successfully implement point-of-injury resuscitation with LTO+ WB. Preliminary evaluation of our first 25 patients has shown a marked decrease in mortality compared to our historic rate using component therapy or crystalloid solutions. Additionally, we have had zero transfusion reactions or seroconversions.Conclusion: Transfusion at the scene within minutes of injury has the potential to save lives. As our utilization expands to our outlying network we expect to see a continued decrease in mortality among significantly injured trauma patients. [ABSTRACT FROM AUTHOR]
