Legal analysis: Clinical blood transfusion hierarchical management system:
1. The blood department must strictly control the indications and contraindications for blood use, use blood resources rationally, avoid waste, and eliminate unnecessary blood transfusion to ensure clinical scientific, reasonable, safe and effective blood transfusion.
2. Indications for blood transfusion shall be strictly implemented in accordance with the "Clinical Blood Transfusion Technical Specifications". In principle, blood transfusion is not required for adults whose blood loss is less than 600ml.
3. If the application for blood transfusion is less than 600ml (or 3U of red blood cells), the application shall be submitted by the treating physician, and the application shall be signed by the attending physician or above for review.
4. If the application for blood transfusion is more than 600ml (or 3U of red blood cells), the application shall be submitted by the treating physician, and the application shall be signed and reviewed by a physician above the deputy director level.
5. If the application for blood transfusion is more than 1000ml (or 5U of red blood cells), the application must be submitted by the treating physician and approved and signed by the department director or deputy director.
Visiting clinical blood transfusions with a one-time reserve of more than 2000m (or more than 10 U of RBC for a single patient) requires the signature of the department director or consultation with a physician from the transfusion department. The director of the blood transfusion department must approve and sign before submitting to the medical department for approval. After emergency use of blood, procedures should be completed in accordance with the above requirements.
