A 42-year-old woman is evaluated in the surgical ward on postoperative day 2 following an open total abdominal hysterectomy for large, symptomatic uterine fibroids. Her preoperative hemoglobin was . Due to symptomatic anemia (fatigue, tachycardia) and a current hemoglobin of , a transfusion of packed red blood cells is initiated. Twenty minutes into the transfusion, the patient reports sudden-onset severe back pain, chills, and shortness of breath. Her urine in the Foley catheter tubing suddenly appears dark red.
Vital signs are as follows:
| Parameter | Value |
|---|---|
| Temperature | () |
| Blood pressure | |
| Heart rate | |
| Respiratory rate | |
| Oxygen saturation | on room air |
Arrange the following steps in the most appropriate chronological order for the immediate management of this patient's condition.
- 1Stop the blood transfusion immediately
- 2Disconnect the blood administration set and attach new intravenous tubing primed with normal saline
- 3Verify the patient's identification band against the attached blood product label
- 4Notify the blood bank and send the remaining blood product and new patient blood samples for analysis
- 5Administer aggressive intravenous crystalloid hydration to maintain brisk urine output
Answer
The correct sequence for managing an acute hemolytic transfusion reaction is: 1) Stop the transfusion immediately, 2) Maintain IV access with completely new tubing and normal saline, 3) Perform a bedside clerical check, 4) Notify the blood bank and send samples for investigation, and 5) Administer aggressive intravenous hydration to prevent acute kidney injury.
The patient is experiencing an acute hemolytic transfusion reaction (AHTR), likely due to ABO incompatibility caused by a clerical error. The immediate sequence of actions must prioritize halting the offending antigen and stabilizing the patient. The very first step is to stop the transfusion. Second, the intravenous line must be kept open to allow for emergency resuscitation; critically, this must be done by completely disconnecting the blood tubing and attaching a new line primed with normal saline, because flushing the old line would push incompatible blood into the patient. Third, a bedside clerical check comparing the blood product to the patient's ID band should be performed, as administrative errors are the most common cause of AHTR. Fourth, the blood bank must be notified and all related materials sent for analysis. Finally, specific medical therapy is initiated, primarily aggressive intravenous hydration with normal saline to induce a brisk diuresis, which helps prevent hemoglobin precipitation in the renal tubules and subsequent acute tubular necrosis.
Step-by-Step Solution
Key Concept
The immediate management of a suspected acute hemolytic transfusion reaction involves sequentially stopping the transfusion, securing IV access with new tubing (avoiding flushing the old blood), verifying patient identity, notifying the blood bank, and providing aggressive supportive care with intravenous fluids to prevent acute tubular necrosis.
