In the UK NHS, blood transfusion is a safety-critical procedure governed by strict clinical guidelines (such as SHOT and BCSH). On the NMC CBT exam, transfusion monitoring and reaction questions are designated as safety-critical. Failing to select the correct bedside check or reaction protocol will result in an automatic exam failure. Here is the absolute clinical standard you must follow.
1. The Bedside Verification Check (Safety-Critical Rule)
The final bedside check is the most critical step in the entire transfusion process and must be performed directly at the patient's bedside by two registered nurses. You must check:
- Patient Identification: Verbally ask the patient to state their full name and date of birth, and match these details precisely with their ID wristband.
- Donor Pack Match: Verify the donor unit number, blood group (ABO and RhD status), and expiration date against the prescription chart and compatibility form.
- Discrepancies: If there is even a single character mismatch, you must stop the process immediately and return the pack to the blood bank. Never administer blood with a discrepancy.
2. Baseline Vitals and the 15-Minute Protocol
You must record the patient's baseline physiological vitals (Pulse, BP, Temp, Respiration) immediately before commencing the transfusion. Once the transfusion starts:
- Strict Monitoring: A registered nurse must remain with the patient and monitor them continuously for the first 15 minutes of the infusion.
- 15-Minute Check: Record a full set of vital signs exactly 15 minutes after commencement. Most severe transfusion reactions (e.g. acute hemolytic, anaphylaxis) occur within this timeframe.
- Ongoing Tracking: If stable, record vitals hourly until the transfusion is complete, and perform a final check at completion.
3. Managing Transfusion Reactions (The Escalation Protocol)
If the patient exhibits signs of a reaction (e.g., sudden fever, rigors, dyspnea, rash, hypotension, or loin pain):
- STOP the transfusion immediately. This is always the very first action.
- Disconnect the blood administration set and maintain IV access by running 0.9% Normal Saline via a completely new administration set.
- Check patient vitals and escalate to the medical team immediately.
- Keep the blood bag and giving set intact for laboratory investigation, and document everything accurately.
