o Roubinian et al. TACO generally occurs near the end of administration of the transfusion or within 6 hours of completion. Transfusion‐associated circulatory overload (TACO) is cardiogenic pulmonary oedema due to infusion of rapid or large volume blood product. Hypertension is a constant feature in TACO whereas it is infrequent and transient in TRALI. Signs and symptoms of TACO and TRALI begin within 6 hours of completion of blood transfusion and include tachycardia, tachypnea, and hypoxia. TACO is defined as acute or worsening respiratory compromise and/or acute or worsening pulmonary oedema during or up to 12 hours of transfusion, with additional features including cardiovascular system changes not explained by the patient’s underlying medical condition; evidence of fluid overload and a relevant biomarker. TACO is a clinical diagnosis and clinical definitions may include evidence of positive fluid balance or cardiac involvement such as left heart failure, elevated blood pressure, or tachycardia. Transfusion-associated circulatory overload (TACO) is an important and potentially injurious complication of transfusion that is underappreciated by clinicians. tachypnoea, shortness of breath, decreased O2 saturations and/or, B. TACO is usually associated with hypertension and responds well to diuretics, TRALI is often associated with hypotension and diuretics have a minimal effect. Symptoms classically occur 7 to 14 days (maximum 30 days) after transfusion with fever, skin rash, diarrhoea, disturbed liver function and worsening bone marrow aplasia. Weigh all patients pre-transfusion(within 1 week) 4. Transfusion associated circulatory overload is prevented by avoiding unnecessary transfusions, closely monitoring patients receiving transfusions, transfusing smaller volumes of blood at a slower rate, and considering the use of furosemide as a diuretic. •Symptoms include SOA, pulmonary edema, fever, hypotension, tachycardia, signs of ARDS •Majority of patients have resolution of symptoms within 96 hours •May see a drop in white count •Most common cause of transfusion-associated death reported to the FDA [citation needed], It is difficult to determine the incidence of TACO, but its incidence is estimated at about one in every 100 transfusions using active surveillance,[10][11] and in one in every 10000 transfusions using passive surveillance. elevation in, This page was last edited on 3 February 2021, at 00:18.

[2] The fluid volume causes hypervolemia. These clinical findings can be blunted, particularly in postoperative or intensive care patients who may not exhibit signs of respiratory distress due to sedation or preexisting ventilatory support. 1. [10] TACO is the most commonly reported cause of transfusion-related death and major morbidity in the UK,[2] and second most common cause in the USA. In the period 2010 to 2019, there were 74 deaths (42.7% of fatalities) reported and 279 cases of major morbidity. TACO is a common transfusion reaction where patient’s experience pulmonary oedema due to excess volume or circulatory overload, resulting in acute respiratory distress.Â.
