Transfusion-associated circulatory overload (TACO) is an important and potentially injurious complication of transfusion that is underappreciated by clinicians. Risk factors for TACO include being at an extreme of age, having preexisting cardiac and/or (potentially) renal dysfunction, acute myocardial infarction, and individuals receiving plasma. Keys to preventing TACO, aside from identifying high-risk individuals, should be multifaceted. We advocate for the widespread use of pretransfusion checklists and implementation of nonemergent transfusion protocols. We suggest the regular use of pretransfusion diuretics in high-risk individuals. When a transfusion is required, we believe that "critical" nursing supervision and leadership are instrumental in the coordination of slow transfusion rates on computerized infusion pumps and ensuring patients are appropriately monitored. We believe that using these methodologies on a global scale will prevent many TACO events and minimize the severity when it does occur.

History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
