16.2 Blood Product Administration

TCO IV.C.2 is blood-product administration technique. Chapter 11.3 already chose the product: irradiated cellular units to prevent transfusion-associated graft-versus-host disease, leukoreduced and cytomegalovirus-safe units per blood-bank policy, platelets for bleeding or a procedure, red cells for symptomatic anemia, and the reaction names transfusion-related acute lung injury (TRALI) and transfusion-associated circulatory overload (TACO). This section is the bedside clock: identifiers, consent, tubing, fluids, the first 15 minutes, and when to stop. A 3-year-old with acute myeloid leukemia (AML) whose red-cell bag is about to spike, a 12-kg toddler whose second unit is hanging too fast, and a 15-year-old who develops hives four minutes into platelets are administration items.

Two-nurse check, consent, vitals, and the first 15 minutes

Informed consent for transfusion is documented before the first drop except in a true life-threatening emergency when delay would kill; even then the team documents why consent could not wait. The consent conversation belongs to the prescriber; the nurse confirms it is on the chart and that the family can still state why the child is being transfused.

Two licensed nurses independently verify the child (name, medical record number, blood bank identification per policy) against the unit tag and the order: product type, ABO/Rh compatibility, donor unit number, expiration, and special attributes. “I already checked it in the medication room” is not an independent check. Mismatch of even one identifier stops the process before the spike.

Obtain a baseline set of vital signs immediately before starting. Stay with the child for the first 15 minutes after the infusion begins—the window when many acute hemolytic and anaphylactic reactions declare. Typical practice is a slow start, then a vital-sign set at about 15 minutes, then per policy for the remainder. Do not leave a toddler with a unit running to “catch up charting” during that first quarter hour. Teach the parent what to call out: new back or chest pain, itching, hives, chills, dyspnea, or a sense of doom in an older child.

Filter, compatible fluids, and the bag tag

Packed red cells run through a standard blood-administration set with a filter (commonly a 170–260 micron clot filter; follow the set in your hand). Do not spike red cells onto ordinary hypotonic tubing “because it was already primed.” Compatible fluid with red cells is 0.9% sodium chloride (normal saline) only. Dextrose can hemolyze red cells in the line. Lactated Ringer’s contains calcium that can clot citrated blood in the tubing. Other medications do not piggyback into the blood set. Platelets and plasma follow the same identity check; some products have product-specific sets—use what the blood bank and insert specify rather than improvising.

Irradiated and leukoreduced (and cytomegalovirus-safe, when ordered) attributes are verified on the bag tag against the order before the spike. A 2-year-old on AML induction whose unit is not labeled irradiated does not get that unit because the fridge was almost empty. Direct the unit back; hang the correctly modified product. Administration is the last chance to catch a product-choice error.

Stop for reaction; emergency drugs; premedication is not universal

Any suspected reaction: stop the transfusion, keep the intravenous line open with normal saline on new tubing if the set is contaminated with the unit, recheck the identity of child and bag, notify the provider and blood bank, and send the remaining product plus required specimens per policy. Do not finish “the last 40 mL.” Isolated hives may later restart a different unit with an antihistamine as ordered; anaphylaxis, hemolysis, TRALI, and TACO do not get a restart of the same bag. Full syndrome tables live in the product-choice chapter; the administration verb is stop.

Keep emergency medications at the bedside (or immediately reachable on the crash cart you have already located): oxygen, epinephrine for anaphylaxis, an antihistamine, and a prescribed diuretic for volume overload. Knowing the room number of the pharmacy is not bedside readiness.

Premedication with an antihistamine or acetaminophen is institutional and patient-specific, not a universal ONCC rule for every pediatric oncology transfusion. A child with prior urticaria may receive a protocol premed; a first-time, well-appearing transfusion does not automatically get acetaminophen that could mask a fever workup. Do not teach families that “we always premed so nothing can go wrong.”

Volume overload and infusion times without a fake ONCC minute

Small children have small vascular space. A 12-kg toddler given a large red-cell aliquot too fast can develop TACO: tachypnea, hypertension, rales, and hepatomegaly. Sit the child up, stop the unit, give the ordered diuretic, and consider splitting future units into aliquots with pauses. Infants and children with cardiac involvement (anthracyclines, mediastinal mass, chronic transfusion cardiomyopathy) are especially intolerant of a “wide-open” adult habit.

Infusion duration follows the product insert and hospital policy. Typical ranges—not ONCC-mandated single minutes—are that red cells are often completed in about 2 to 4 hours and are not left hanging beyond 4 hours from spike because of bacterial-growth risk; platelets and plasma usually infuse faster, often over about 30 to 60 minutes as the child and volume allow. Do not memorize one ONCC minute number. Do not stretch a red-cell unit over an entire night shift “so it is gentler” past the spiked-time limit. Do not bolt a full adult unit into a toddler because the next patient is waiting.

A 3-year-old whose two nurses matched an irradiated, leukoreduced red-cell unit to the armband, whose family signed consent, whose vitals were taken, whose nurse stayed 15 minutes, and whose tubing contained only normal saline is the CPHON administration product. A unit that was “probably fine” because the child “gets blood all the time” is not.
