What is transfusion-associated circulatory overload?
What is transfusion-associated circulatory overload?
Transfusion-associated circulatory overload (TACO) is a common transfusion reaction in which pulmonary edema develops primarily due to volume excess or circulatory overload.
What is the difference between TRALI and TACO?
Diagnostically, it remains very challenging to distinguish TACO and TRALI from underlying causes of lung injury and/or fluid overload as well as from each other. TACO is characterized by pulmonary hydrostatic (cardiogenic) edema, whereas TRALI presents as pulmonary permeability edema (noncardiogenic).
What are the typical signs of transfusion related circulatory overload?
Symptoms include dyspnea, orthopnea, cough, chest tightness, cyanosis, hypertension, and headache. Symptoms usually present at the end of transfusion but may occur up to 6 hours posttransfusion.
How do you identify tacos?
Some signs and symptoms that may be present in a patient with TACO include: dyspnea, orthopnea, cyanosis, hypoxemia, elevated BNP, tachycardia, hypertension, pulmonary edema, pedal edema and cardiomegaly.
How do you manage TRALI?
Treatment / Management Immediate management of TRALI is to stop the transfusion and notify the blood bank to screen the donor unit for antileukocyte antibodies, anti-HLA or anti-neutrophil-specific antibodies. [5] Supportive measures must be taken to improve oxygenation.
How can TRALI be prevented?
There have been several other suggestions for preventing TRALI, which include:
- Screening of all donors for anti-neutrophil or anti-HLA antibodies.
- Use of pre-storage leukoreduced blood.
- Appropriate utilization of blood products.
How is TRALI diagnosed?
To diagnose TRALI, physical exam, chest x-ray, and arterial blood gas studies are recommended. In distinguishing TRALI from TACO, an echocardiogram may be useful in determining whether the observed pulmonary edema is of cardiogenic origin.
How is transfusion-associated circulatory overload treated?
Stop transfusion immediately and follow other steps for managing suspected transfusion reactions. Place the patient in an upright position and treat symptoms with oxygen, diuretics and other cardiac failure therapy. In serious cases, mechanical ventilation and treatment in the intensive care unit (ICU) may be required.
What happens during circulatory overload?
Transfusion associated circulatory overload includes any four of the following occurring within 6 h of a BT[3] – acute respiratory distress, tachycardia, increased blood pressure (BP), acute or worsening pulmonary edema and evidence of a positive fluid balance.
What is TA GVHD?
Transfusion-associated graft-versus-host disease (ta-GVHD) is a rare and usually fatal complication of blood transfusion in which lymphocytes from the transfused blood component attack the recipient’s tissues, especially the skin, bone marrow, and gastrointestinal tract.
What does taco stand for?

How can taco blood transfusions be avoided?
How to prevent. In susceptible patients at risk for TACO (elderly or paediatric patients, patients with severe anaemia and patients with congestive heart failure or renal disease), transfusion should be administered slowly and consideration given to the use of a diuretic.
