সংজ্ঞা
Plasmapheresis is done to exchange plasma in the blood. Plasma is the liquid part of the blood that does not contain cells. Once the plasma is removed, fresh plasma or a plasma substitute is added back to the blood.
পদ্ধতির কারণ
Plasmapheresis removes autoantibodies from the blood. Autoantibodies are proteins found in plasma. They mistakenly attack your body’s own tissues. In some cases, this procedure is used to remove toxins or metabolic substances from the blood.
Plasmapheresis is used to treat the following:
- Autoimmune diseases—conditions that occur when the body’s immune system attacks its own tissues and organs
- Neurological diseases—disorders affecting the nervous system
- Very high levels of cholesterol that are not reduced by diet and medicines
- Toxins that can get into your blood
সম্ভাব্য জটিলতা
Complications are rare, but no procedure is completely free of risk. If you are planning to have plasmapheresis, your ডাক্তার একটি তালিকা পর্যালোচনা করবে সম্ভাব্য জটিলতা, যার মধ্যে অন্তর্ভুক্ত থাকতে পারে:
- Anaphylaxis—a dangerous allergic reaction to the solutions used in plasma replacement, which usually starts with itching, wheezing, or a rash.
- Mild allergic reaction to the procedure—may cause fever, chills, or rash
- সংক্রমণ
- রক্তপাত
- Drop in blood pressure
- Bruising or swelling
Plasmapheresis may not be appropriate for people with certain clotting disorders.

পদ্ধতির বর্ণনা
Plasmapheresis is done using an apheresis machine. The machine works in one of two ways. In the first method, the blood cells may be separated from the plasma by spinning the blood at high speeds. The second method uses a special membrane. The membrane has tiny pores that only the plasma can pass through, leaving the blood cells behind.
You will be asked to lie in a bed or sit in a reclining chair. Two needles attached to a catheter tube will be inserted into veins. In some cases, a needle will be inserted into each arm. For others, one needle may be inserted into your arm and the other into the opposite foot. If the veins in your limbs are too small to use, a long-duration catheter will be inserted. It will be placed in a vein in your shoulder or groin area.
Blood will be taken out of your body through one of the catheter tubes. It will then go into the apheresis machine. Once in the machine, the blood cells will be separated from the plasma. The blood cells will be mixed with replacement plasma or a plasma substitute. The new mixed blood will then be returned to your body through the other tube.
