Plasmapheresis is the removal, treatment, and return of (components of)
blood plasma from blood circulation. In plasmapheresis or therapeutic
plasma exchange <TPE> large quantities of plasma are removed and
replaced with fresh frozen plasma, albumin and / or saline
Indication: Examples of diseases that can be treated with plasmapheresis:
Idiopathic pulmonary fibrosis
Guillain-Barre syndrome
Miller Fisher syndrome[7]
Chronic inflammatory demyelinating polyneuropathy
Good pasture's syndrome
Hyper viscosity syndromes:
o Cryoglobulinemia
o Paraproteinemia
o Waldenström macroglobulinemia
Myasthenia gravis
Thrombotic thrombocytopenic purpura (TTP)/hemolytic uremic
syndrome
Wegener's granulomatosis
Lambert-Eaton Syndrome
Antiphospholipid Antibody Syndrome (APS or APLS)
Microscopic polyangiitis
Recurrent focal and segmental glomerulosclerosis in the transplanted
kidney
HELLP syndrome
PANDAS syndrome
Refsum disease
Behcet syndrome
HIV-related neuropathy[8]
Graves' disease in infants and neonates
Pemphigus vulgaris
Neuromyelitis optica
Multiple sclerosis
Rhabdomyolysis
Toxic Epidermal Necrolysis (TEN)
Procedure of plasmapheresis:
A: Centrifugal plasma separation : blood cells are separated during
centrifugation , there are two centrifugation methods Intermittent flow
device and continuous flow device
B: membrane plasma separation : plasma separators use membranes with a
molecular weight 3 million
Estimation of plasma volume:
There are several equations
1-The plasma volume is estimated 35- 40 ml\ kg. 35ml is applicable to the
patient with normal Hct value and 40 ml\ kg is applicable to the patient with
low Hct
2- there is a simplified method for predicting the estimated plasma volume is
{0.065 xweight( kg) x {1-Hct}
Choice of replacement solution:
A: albumin : its advantage there is no risk of hepatitis , stored at room
temperature , allergic reaction are rare, depletes inflammation mediators
, but its disadvantage as its very expensive and no coagulation factor
and no immunoglobulin
B: fresh frozen plasma: advantage : has coagulation factors and
immunoglobulin , its disadvantage : risk of hepatitis, HIV .
Allergicreaction.Hemolytic reaction
Complication of plasmapheresis:
Related to the vascular access
1-Hematoma
2-Pneumothorax
3-Retroperitoneal bleed
Related to the procedure
1-Hypotension: can be avoided by adjust volume balance and should measure
the blood pressure every half hour
2-Bleeding: can be treated by two unite of fresh frozen plasma at the end of
session
3-Edema
4-Loss of cellular element
5-Hypersensitivity reaction: can be avoided by premedication for the
sensitized individual
a: prednisone 50 mg orally 13 hours , 7hours , 1 hour before treatment
b. diphenhydramine 50 mg orally 1 hour before treatmen
c: ephedrine 25 mg orally 1 hour before treatment
Related to anticoagulation
1-Bleeding
2- Hypocalcemic symptom: can be treated by prophylactic 10% CaCl
during treatment
3-Arrhythmia: due to hypokalemia which can be avoided by ensure
serum potassium concentration of 4 mm in the replacement solution
4-Hypotension
5-Numbness and tingling
6-Metabolic alkalosis from citrate
Post procedure:
We should do serum calcium, serum k& CBC to the patient
The plasmapheresis technique is consider as immunosuppressive therapy so
the patient should be isolated.
