Overview

Blood transfusion is the process of transferring blood or blood products obtained from one person (donor) into the circulatory system of another (recipient).

Massive blood transfusion refers to transfusing a large volume of blood to a patient, especially in trauma patients with uncontrollable hemorrhage. Several definitions used in the past include:

  • Transfusion of 20 units of red blood cells (RBCs) in 24 hours.[1]
  • Transfusion of greater than 10 units of RBCs in 24 hours.[2]

Currently, it is more practical to identify patients in need of massive transfusion when greater than four red blood cell units is needed in one hour and an ongoing need for transfusion is predicted,[3] or when 50% of total blood volume is replaced within 3 hours. These situations often require the activation of massive transfusion protocols (MTP).[4]

Blood Products and Indications for Use

Blood Products Indications Dose
Packed red blood cells
(PRBC)
Acute hemorrhage
❑ To ↑ O2-carrying capacity of blood in cases of end-organ ischemia
1 unit of PRBC = ↑ Hemoglobin (Hb) concentration by 1 g/dL
Transfuse slowly for the first 15 minutes
Complete transfusion within 4 hours.
Platelets (Plts) In patients with thrombocytopenia (plts < 150,000 cells/uL)
❑ For prophylaxis (to prevent bleeding)
❑ For treatment (during active bleeding)
Contraindications
TTP/HUS, HIT, HELLP syndrome

1 apheresis unit = 6 units of plts in 250 - 300 mls of plasma
1 dose of apheresis unit = ↑ plt count by 30,000 - 60,000/uL
Infuse over 30 - 60 minutes
Fresh frozen plasma ❑ For bleeding patients due to multiple deficiencies of coagulation factors
e.g., TTP/HUS, hepato-biliary diseases
Warfarin-induced bleed (2nd choice)
1 unit = 200 - 250 ml of plasma
1 ml of plasma = 1 u coagulation factors
1 unit contains 220 u coagulation factors
'A dose of 10-20 mL/kg (4-6 units) = 20% ↑ of circulating coagulation factors
Note - specific coagulation factor concentrates should be used to treat
patients with hemophilia , Von Willebrand disease, and antithrombin III deficiency
Cryoprecipitate ❑ Bleeding patients with fibrinogen < 100 mg/dL
❑ Bleeding patients with Von Willebrand disease and factors VIII and XIII deficiencies
Note - specific coagulation factor concentrates should be used to treat
patients with hemophilia , Von Willebrand disease
1 unit = fibrinogen (150 mg), factor VIII (80-120 u), von Willebrand factor (40-70 u),
and factor XIII (20-30 u)


1 dose = ↑ circulating fibrinogen concentration by 50-100 mg/dL

Irradiated cellular products ❑ Patients at risk of transfusion-associated graft-versus-host disease
❑ Stem cell transplant candidates
❑ HLA-matched platelet product recipients
❑ Patients on fludarabine
❑ Patients with congenital immunodeficiency

Management

General Approach

 
 
Characterize the symptoms:

Low red blood cell count or low hemoglobin level

❑ Difficulty concentrating
Difficulty sleeping
Dizziness
Easy fatigability
Headache
Pale skin
Rapid heart beat
Shortness of breath

Low white blood cell count

❑ Abnormal bleeding
Fever
Irritability
Neurasthenia
❑ Recurrent infections - canker sores, gingivitis, periodontitis

Low platelet count

❑ Blood in urine or stool
❑ Easy or excessive bruising
Heavy menstrual flow
❑ Prolonged bleeding during surgery
or after tooth extraction
❑ Prolonged bleeding from cuts
 
 
 
 
 
 
 
 
 
 
Obtain a detailed history:

❑ Review medical records
❑ Past medical history

❑ Previous blood transfusion
❑ Cardiovascular disease
Hypertension
Arryhthmias
Trauma
❑ Previous surgery
Infections e.g., HIV
Malignancy
Chronic kidney disease
Chronic lung disease
Malignancy

Pregnancy

Medications - anticoagulants, thrombolytics
 
 
 
 
 
 
 
 
 
 
Examine the patient:

❑ Vital signs:

Blood pressure: ↓
Pulse rate: ↑ or ↓
Respiratory rate: ↑ or ↓
Oxygen saturation: ↓ (<90%)
Temperature: ↑ or ↓ in sepsis
❑ Skin:
Pallor
Jaundice
Petechiae, ecchymosis
Active bleeding
❑ Central nervous system:
Altered sensorium
❑ Personality changes
❑ Lungs:
❑ Abdomen:
Abdominal distension
Abdominal tenderness
 
 
 
 
 
 
 
 
 
 
 
Order laboratory tests (Routine):

CBC
Serum electrolytes
BUN, creatinine
PT/PTT
❑ Type and screen (when transfusion is unlikely)
❑ Type and crossmatch (if transfusion is certain)

ABO antigens and antibodies
Rhesus (D) antigen
❑ Antibodies to red cell antigens (antibody screen)

Note - Send fresh samples whenever a second transfusion is required


Other additional laboratory tests to determine etiology:








 
 
 
 
 
 
 
 
 
 
 
Pre-transfusion preparation:

4 R's - right Blood, right Patient, right Time, right Place
❑ Intravenous access/sample collection

❑ Large-bore cannula
❑ Use bottle containing EDTA anticoagulant (purple color)
❑ Avoid using IV site for drugs
Dextrose solution (cause hemolysis)
Calcium-containing solutions (cause clotting of citrated blood)

Precaution against errors

❑ Bleed only one patient at a time
❑ Ensure two independent patient identifiers
❑ Proper labelling of samples
❑ Record date and time of blood or blood component

❑ Bleeding patient

❑ Stop all anticoagulation - heparin, warfarin
❑ Reverse anticoagulants, if necessary

❑ Record vital signs

❑ Give adequate volume of crystalloids
to maintain normal blood pressure

❑ Monitor urine output (>30 ml/hr) or 0.5 ml/kg/hr
