Rapid review II: the first fifteen minutes of a transfusion

The opening move

Stop the transfusion. Do not flush the blood remaining in the tubing into the patient, because that delivers more of the product you just decided is harming them. Disconnect the blood tubing and keep the line open with normal saline through new tubing. Stay with the patient and take vital signs. Only then notify the provider and the blood bank, and return the unit with the required samples.

Setup facts that prevent reactions

• Two-person verification of patient identity and unit identification at the bedside, per institutional policy.
• Baseline vital signs before the unit is spiked.
• A large-bore catheter, with gauge set by policy.
• Normal saline is the only solution compatible at the blood line.
• Start slowly, stay at the bedside for the first fifteen minutes, and complete the unit within the window policy allows.

The seven reactions

• Acute hemolytic, from ABO incompatibility. Minutes in. Fever, chills, flank or back pain, hypotension, red or dark urine, a sense of impending doom, and consumptive coagulopathy behind it.
• Febrile nonhemolytic, the most common. A temperature rise with chills and no hypotension. It still requires stopping, because at the bedside it cannot be told apart from hemolysis.
• Mild allergic. Hives and itching only, with no fever and no respiratory involvement. The single reaction where restarting is ever considered, and only under policy.
• Anaphylactic, classically in immunoglobulin A deficiency. Seconds to minutes. Wheezing, stridor, shock. Epinephrine, and washed products for future transfusions.
• Transfusion-related acute lung injury. Within six hours. Abrupt hypoxemia with bilateral infiltrates and no evidence of volume overload. It does not respond to a diuretic.
• Transfusion-associated circulatory overload. Dyspnea with hypertension, jugular venous distension, and crackles. It does respond to slowing or stopping, sitting the patient upright, and diuresis.
• Bacterial contamination. Rapid high fever with rigors and hypotension, more often with platelet units, which are stored at room temperature.

Memory hookSTOP · SALINE · STAY · SEND. Stop the transfusion, saline through new tubing, stay with the patient, send the unit and samples back.

Watch outflushing the tubing after stopping is the classic wrong first action, and it gives the patient more of the offending product at the worst possible moment.

Policy-dependent, and labeled as such: the observation interval, vital sign frequency, catheter gauge, unit completion window, and whether a resolved mild allergic reaction may be restarted are all set by institutional policy. Every procedural claim on this page is verified against current AABB Standards for Blood Banks and Transfusion Services; confirm your facility's protocol before you act.

Takeawaystopping the infusion precedes assessment, documentation, and every drug, and transfusion-related acute lung injury versus circulatory overload is decided by the blood pressure and by the response to a diuretic.
