BACKGROUND: AABB Standard 5.27 requires transfusion services to have a process for urgent release of blood before completion of compatibility testing. Our institution endorses a policy for the emergency release of group O, D+ red blood cells (RBC; O+ RBC) to males and females at least 50 years of age. Our emergency department (ED) stocks 4 O- RBC units. To determine if O+ RBCs can replace ED O- RBCs, we performed a retrospective review. STUDY DESIGN AND METHODS: Patients admitted to the ED between January 2001 and August 2011 and transfused emergency-release O- RBCs were identified...

When Rh-negative persons are given transfusions of Rh-positive blood, more than 50 per cent are sensitized to the Rh(0) factor. Such sensitization of female children may be the cause of hemolytic disease in their offspring many years later, while severe hemolytic reactions may follow a second transfusion of Rh-positive blood in either sex. The gross hemolysis of transfused blood may be entirely asymptomatic, however. In one case a pint of blood was completely hemolyzed within two hours without producing symptoms...

In past and ongoing military conflicts, the use of whole blood (WB) as a resuscitative product to treat trauma-induced shock and coagulopathy has been widely accepted as an alternative when availability of a balanced component-based transfusion strategy is restricted or lacking. In previous military conflicts, ABO group O blood from donors with low titers of anti-A/B blood group antibodies was favored. Now, several policies demand the exclusive use of ABO group-specific WB. In this short review, we argue that the overall risks, dangers, and consequences of "the ABO group-specific approach," in emergencies, make the use of universal group O WB from donors with low titers of anti-A/B safer...

Antibody-induced hemolytic transfusion reactions were first described over 300 years ago. Indeed, during its early evolution, transfusion medicine focused almost exclusively on issues in immunohematology to prevent such events. However, despite the best of efforts to avoid them, incompatible transfusions still occur, through both error and an inability to obtain compatible red blood cells for patients who are alloimmunized against multiple antigens. Because transfusing units of incompatible blood is potentially lethal, studies on human volunteers are not ethical...

Blood transfusion is one of the most common procedures in patients in hospital so it is imperative that clinicians are knowledgeable about appropriate blood product administration, as well as the signs, symptoms, and management of transfusion reactions. In this Review, we, an international panel, provide a synopsis of the pathophysiology, treatment, and management of each diagnostic category of transfusion reaction using evidence-based recommendations whenever available.

BACKGROUND: Hemorrhage is the most common cause of early death in trauma patients. Massive transfusion protocols (MTPs) have been designed to accelerate the release of blood products but can result in waste if activated inappropriately. The Assessment of Blood Consumption (ABC) score has become a widely accepted score for MTP activation. In this study, we compared the use of ABC criteria to physician judgment in MTP activation. METHODS: Adult trauma patients treated at University of Louisville Trauma Center from January 2016 to December 2016 were studied...

Toward the end of World War I and during World War II, whole-blood transfusions were the primary agent in the treatment of military traumatic hemorrhage. However, after World War II, the fractionation of whole blood into its components became widely accepted and replaced whole-blood transfusion to better accommodate specific blood deficiencies, logistics, and financial reasons. This transition occurred with very few clinical trials to determine which patient populations or scenarios would or would not benefit from the change...

Recent combat experience reignited interest in transfusing whole blood (WB) for patients with life-threatening bleeding. US Army data indicate that WB transfusion is associated with improved or comparable survival compared to resuscitation with blood components. These data complement randomized controlled trials that indicate that platelet (PLT)-containing blood products stored at 4°C have superior hemostatic function, based on reduced bleeding and improved functional measures of hemostasis, compared to PLT-containing blood products at 22°C...

PURPOSE OF REVIEW: We present data comparing whole blood with blood components and summarize the data that support increased availability of whole blood for patients with life-threatening bleeding. RECENT FINDINGS: Recent data indicate that whole-blood transfusion is associated with improved or comparable survival compared with resuscitation with blood components. These data complement randomized controlled trials indicating that platelet-containing blood products stored at 4 °C have superior hemostatic function, compared with platelet-containing blood products at 22 °C...

PURPOSE OF REVIEW: Traumatic injuries are a major cause of mortality worldwide. Damage control resuscitation or balanced transfusion of plasma, platelets, and red blood cells for the management of exsanguinating hemorrhage after trauma has become the standard of care. We review the literature regarding the use of alternatives to achieve the desired 1 : 1:1 ratio as availability of plasma and platelets can be problematic in some environments. RECENT FINDINGS: Liquid and freeze dried plasma (FDP) are logistically easier to use and may be superior to fresh frozen plasma...

The military's use of whole-blood transfusions is not new but has recently received new emphasis by the Tactical Combat Casualty Care Committee. US Army units are implementing a systematic approach to obtain and use whole blood on the battlefield. This case report reviews the care of the first patient to receive low titer group O whole blood (LTOWB) transfusion, using a new protocol.

The mortality from hemorrhage in trauma patients remains high. Early balanced resuscitation improves survival. These truths, balanced with the availability of local resources and our goals for positive regional impact, were the foundation for the development of our prehospital whole blood initiative-using low-titer cold-stored O RhD-positive whole blood. The main concern with use of RhD-positive blood is the potential development of isoimmunization in RhD-negative patients. We used our retrospective massive transfusion protocol (MTP) data to analyze the anticipated risk of this change in practice...

BACKGROUND: The use of cold-stored low-titer group O whole blood (LTOWB) for civilian trauma patients is gaining popularity. However, hemolysis might occur among non-group O recipients. This study evaluated the serologic safety of transfusing up to 4 units of LTOWB. STUDY DESIGN AND METHODS: Hypotensive male and at least 50-year-old female trauma patients who received leukoreduced, uncrossmatched, group O+, low-titer (<50 anti-A and anti-B), platelet-replete whole blood during initial resuscitation were included in this prospective, observational study...

OBJECTIVE: To evaluate the feasibility, limitations and costs involved in providing prehospital trauma teams with packed red blood cells (pRBCs) for use in the prehospital setting. METHODS: A retrospective cohort study, examining 18 months of historical data collated by the Queensland Ambulance Service Trauma Response Team (TRT) and the Pathology Queensland Central Transfusion Laboratory was undertaken. RESULTS: Over an 18-month period (1 January 2011-30 June 2012), of 500 pRBC units provided to the TRT, 130 (26%) were administered to patients in the prehospital environment...
