Study Notes
Unit IV - Blood Safety: Blood Products Use & Storage
- The unit focuses on the safe use and storage of blood products.
- Objectives include describing blood products, their use and storage, blood transfusion rights, and transfusion procedures.
Types of Blood Products
- Rhesus factor
- ABO Groups
- ABO Groups antigens and antibodies
- Whole blood
- Plasma
- Packed cells & Platelets
Blood Cold Chain
- A systematic process for safe storage and transportation of blood from collection to transfusion.
- Regulated by the World Health Organization (WHO).
Blood & Blood Product Storage
- Blood is cooled to 4°C and maintained at that temperature until transfusion.
Blood Components
- Blood consists of:
- Blood vessels
- White blood cells
- Plasma
- Platelets
- Red blood cells
Blood Products Use and Storage
- Whole blood
- Plasma
- Cryoprecipitate
- Packed cells & platelets
Important Fact
- Each blood product must be tested and labeled. This labeling must include product type, storage requirements, expiry date, and any modifications. It should also include relevant information such as ABO group and Rh factor (WHO 2021).
Readings
- Refer to WHO Education Modules on The Clinical Use of Blood (2021) using the online link provided.
- Specifically, chapters 3 and 4 are relevant.
Blood Composition
- Plasma (55% by volume)
- Water (91% by weight)
- Protein (7% by weight)
- Albumin (58%)
- Globulins (38%)
- Fibrinogen (4%)
- Other Solutes (2%)
- Formed elements (45% by volume)
- Platelets (250,000-400,000 per cubic millimeter)
- White blood cells (5,000-9,000 per cubic millimeter)
- Neutrophils (60-70%)
- Lymphocytes (20-25%)
- Monocytes (3-8%)
- Eosinophils (2-4%)
- Basophils (0.5-1%)
- Red blood cells (4.2-6.2 million per cubic millimeter)
How Blood Products are Made
- Refer to the provided YouTube link for information on the process.
Rights of Transfusion
- Right blood / blood product
- Right patient
- Right time
- Right environment
- Right documentation
- Right disposal
What Makes a Transfusion Safe
- Sourced from a selected healthy donor
- Free from infections
- Processing using reliable testing methods & production, storage & transportation of components
- Transfused as needed for patient health
Safety – Blood Storage
- Whole blood and red blood cells must be stored between +2°C and +6°C.
- Blood's oxygen-carrying capacity decreases if not stored at proper temperature
- Anticoagulant/preservative solutions in blood bags provide nutrients, prevent clotting, and maintain viability.
- Red blood cells can carry and deliver oxygen only if they remain viable.
Standard Procedures for Transfusion
- Ordering blood products for elective surgery
- Ordering blood products for emergency cases
- Completing blood request forms
- Taking pre-transfusion samples (group & cross-match)
The Transfusion Process (Steps)
- Identify the patient
- Explain the procedure to the patient and obtain consent
- Wash hands
- Gather all equipment
- Establish baseline vital signs
- Verify five rights with another licensed practitioner.
- Use sterile equipment
- Check the unit of blood thoroughly
- Be sure Blood is body temperature before transfusion
- Appropriate slow rate to prevent increased load on the heart
- Continuous monitoring for the first 10-15 minutes and subsequently.
