Praxis Medical Insights

Positive patient identification is paramount prior to any blood transfusion episode to minimize wrong-blood-in-tube events and risks of ABO incompatibility, as recommended by the American Society of Anesthesiologists 1
The American Society of Anesthesiologists recommends that all patients receiving a blood transfusion must wear a patient identification band with minimum identifiers including surname, forename, date of birth, and hospital unique identification number 1
For patients with unknown identity, the American Society of Anesthesiologists suggests following local guidelines using at least one unique identifier (e.g., randomly generated number with prefix) 1
Review of previous medical records and interview of the patient or family is necessary to identify previous blood transfusion history, history of drug-induced coagulopathy, presence of congenital coagulopathy, and history of thrombotic events, according to the American Society of Anesthesiologists 2
The American Society of Anesthesiologists recommends discussing specific transfusion risks with patients, including infectious risks, immunologic risks, and immunomodulatory effects 1

Pre-transfusion Assessment and Benefit Discussion

The American Society of Clinical Oncology suggests that the intended use of blood products is to reduce red blood cell transfusion requirements 5
The American Society of Anesthesiologists recommends explaining the specific benefits of transfusion for the patient's condition and discussing expected outcomes based on the patient's clinical situation 2

The American Society of Anesthesiologists presents available alternatives to allogeneic blood transfusion, including cell salvage for surgical patients and erythropoietin with or without iron for selected patient populations 2
The American Society of Anesthesiologists discusses options such as cell salvage for surgical patients, as recommended by the Anaesthesia journal 6

The American Society of Anesthesiologists recommends monitoring vital signs throughout transfusion to identify and manage adverse reactions, including observing respiratory rate and recording observations at minimum before transfusion start, 15 min after start of each unit, and within 60 min of transfusion end 1
The American Society of Anesthesiologists suggests that TACO is now the most common cause of transfusion-related mortality and major morbidity, and recommends risk factors assessment, body weight dosing of RBCs, slow transfusion rates, close monitoring of vital signs and fluid balance, and prophylactic diuretic administration in high-risk patients 1

The American Society of Anesthesiologists recommends that all hospitals should have clear policies for transfusion when patient identity is unknown or in emergency situations, and follow local emergency transfusion protocols 4
The American Society of Anesthesiologists suggests verifying the four core identifiers on the compatibility label with the patient's identification immediately before transfusion, as recommended by the Anaesthesia journal 6
