Saleh Owimer: The Critical Rules of Safe Blood Transfusion
Saleh Owimer, Nursing Supervisor at Cleopatra Hospitals Group, shared on LinkedIn:
”This blood bag… is a ‘ticking time bomb’ if it isn’t handled carefully.
In the past, blood transfusions were done with minimal observation.
But the latest guidelines from the AABB and JCI have introduced strict rules because fatal transfusion errors are not something to take lightly.
Why?
Because most transfusion-related deaths occur due to human errors in patient identification (clerical errors).
The safe prescription for performing a blood transfusion with confidence:
- The 30-Minute Rule
Once the blood unit leaves the refrigerator, you only have 30 minutes to start the transfusion.
If it takes longer than that, bacterial growth may begin and the blood can deteriorate.
- The 4-Hour Rule
The blood unit must be completely transfused within 4 hours of leaving the blood bank.
If this time is exceeded, discard the unit immediately because it becomes unsafe for the patient.
- The Double Check (The Most Critical Step)
A single nurse must never verify the information alone.
At least two nurses must check the following at the patient’s bedside:
- Patient name
- Medical record number
- Blood group
- Blood bag number
- Expiry date
The only IV fluid compatible with blood:
Normal Saline 0.9%
Never mix blood with Ringer’s solution or glucose solutions.
Ringer’s lactate contains calcium, which can cause blood clotting in the line.
Glucose solutions can lead to red blood cell hemolysis.
If a Transfusion Reaction occurs… what should you do?
‘So what should we do, Mr. Blood Bag?’
The blood bag replies:
‘First of all, always follow your hospital’s transfusion protocol.’
‘The moment the patient develops chills, itching, shortness of breath, or back pain… stop me immediately!’
Step 1: Stop the transfusion immediately.
Step 2: Replace the entire IV set and start a new line with normal saline to keep the vein open.
Step 3: Inform the physician and the blood bank immediately.
Step 4: Send the blood bag with its tubing, along with blood and urine samples, to the laboratory for investigation.
Step 5: File an OVR (occurrence/incident report) and document what happened according to hospital policy.
A small but important point:
Why are we particularly concerned about back pain?
Because it can be a sign of an Acute Hemolytic Transfusion Reaction.
This means the blood groups are incompatible, causing the body to destroy the transfused red blood cells.
The breakdown products can severely damage the kidneys, potentially leading to acute kidney failure if not managed promptly.
My dear colleague…
Doing your job correctly is what protects the patient and makes you stand out as a true professional.
