When monitoring a patient 2 hours post-transfusion, the nurse must prioritize assessment findings that indicate an acute transfusion reaction (ATR). The most critical indicator is a new onset of fever (temperature increase ≥1°C or ≥2°F from baseline) accompanied by chills or rigors. This presentation is the hallmark of a febrile non-hemolytic transfusion reaction (FNHTR) and can also be the earliest sign of a life-threatening acute hemolytic reaction or bacterial contamination.
Immediate Nursing Actions
- Stop the Transfusion Immediately: Disconnect the blood tubing from the intravenous access. Do not flush the line with the remaining blood product.
- Maintain IV Access: Keep the vein open with a new infusion of 0.9% normal saline using new tubing to maintain hemodynamic stability and allow for emergency medication administration.
- Monitor Vital Signs Closely: Assess temperature, blood pressure, heart rate, respiratory rate, and oxygen saturation every 5-15 minutes. Watch for signs of deterioration such as hypotension, tachycardia, dyspnea, or flank pain which may indicate a severe hemolytic reaction.
- Verify Patient and Product Identification: Recheck the patient's identification band, blood unit number, and compatibility tags at the bedside to rule out a clerical error leading to an ABO incompatibility.
- Notify the Provider and Blood Bank: Report the reaction immediately. Prepare to collect blood and urine samples as ordered for direct antiglobulin test (DAT), serum haptoglobin, plasma-free hemoglobin, and urinalysis.
- Document Thoroughly: Record the time of onset, specific symptoms, vital sign trends, volume of blood infused, and all interventions performed in the medical record.
Mild, isolated changes such as a slight decrease in blood pressure (e.g., 120/80 to 110/70 mmHg), a minor increase in heart rate (e.g., 78 to 88 bpm), or a small dip in oxygen saturation (e.g., 98% to 96%) are nonspecific and can be attributed to volume shifts, anxiety, or sensor artifact. While these should be monitored, they do not warrant immediate cessation of the transfusion in the absence of a febrile response or other cardinal signs like urticaria, respiratory distress, or pain.
