Discussion on a Case of “Urgent” Blood Transfusion in Clinical Application

Objective-To explore the clinical application of emergency blood transfusion in situations where the patient's blood type is unknown and there is no time to perform crossmatching.Methods-For patients requiring transfusion without known blood type and without prior crossmatching, the emergency transfusion protocol outlined in the Recommended Scheme for Emergency Rescue Transfusion under Special Circumstances was implemented.Upon receiving an "urgent" transfusion request form or an emergency transfusion call from the attending physician, the transfusion department was required to issue blood to the clinical unit within 15 minutes for immediate transfusion.The transfusion department promptly selected one to two units of type "O" RhD-positive suspended red blood cells, verified the blood type again to ensure correctness, and then dispatched the blood for clinical transfusion.The blood unit's barcode tag was retained.Once the patient's blood type and crossmatching specimens were received, blood typing and crossmatching with the dispatched unit were immediately performed, and the results were promptly communicated to the clinical team.Clinicians were reminded to closely monitor the patient for any transfusion reactions.Results-Patients undergoing emergency "urgent" transfusion received timely and effective treatment.Conclusion-In extremely urgent situations where the patient's blood type is unknown and crossmatching cannot be performed in time, the prompt implementation of the Recommended Scheme for Emergency Rescue Transfusion under Special Circumstances is essential.This approach facilitates life-saving treatment, provides critical time for clinical intervention, and helps mitigate medical risks for clinical departments.
