Packed Red Blood Cell (PRBC) Transfusion
A procedure that transfers concentrated red blood cells into your bloodstream through an intravenous (IV) line to treat anemia or blood loss and restore your body's ability to carry oxygen.
{"Replaces missing red blood cells to improve oxygen delivery","Commonly used during surgery, trauma, or severe anemia","Performed by trained medical staff with careful monitoring","Involves blood type matching to prevent reactions","May cause temporary side effects like fever or chills"}

What is this test?
Packed red blood cell (PRBC) transfusion is a medical procedure where concentrated red blood cells are given to a patient through an intravenous (IV) line. Red blood cells carry oxygen throughout your body, and this transfusion helps increase your body's ability to transport oxygen when your own red blood cell count is too low.
Why is it needed?
This transfusion may be recommended when you have significantly low hemoglobin or hematocrit levels, which can occur due to heavy bleeding during surgery, trauma, certain diseases, or conditions that affect blood cell production. It helps restore your body's oxygen-carrying capacity and improve your overall condition.
What happens during the procedure?
Before transfusion, your blood will be typed and matched to ensure compatibility. A healthcare professional will insert an IV line and monitor you closely throughout the process. The transfusion typically takes 1-4 hours depending on how many units are needed and your medical condition. Vital signs are checked regularly during and after the procedure.
What are the risks?
While generally safe, possible risks include allergic reactions, fever, chills, shortness of breath, or in rare cases, more serious complications. Your medical team is trained to recognize and treat these reactions promptly. The benefits of transfusion usually outweigh these risks when the procedure is medically necessary.
Reference range
Adult males: 4.2-5.9; Females: 3.8-5.1 x 10^12/LN/A
Obtain informed consent. Verify patient identity and blood product compatibility. Confirm type and crossmatch has been completed. Assess vital signs prior to transfusion. Ensure appropriate IV access (18-20 gauge). Verify physician order for specific number of units.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Packed red blood cell transfusions are critical in cardiac care for patients undergoing heart surgery, those with acute blood loss, or patients with chronic anemia from conditions like heart failure. Maintaining adequate oxygen-carrying capacity is essential for heart function and overall cardiovascular stability. This procedure helps improve tissue oxygenation and supports recovery in cardiac patients.
The number of units transfused (recorded as 'units [#]') indicates the volume of red cells given and helps healthcare providers assess treatment response and plan further care. In cardiac patients, transfusion thresholds are carefully considered to balance oxygen delivery needs with potential risks.
