Presentation on Plasmapheresis

1. PLASMAPHERESIS PLASMAPHERESIS DEFINITION; Plasmapheresis is an experimental procedure conducted in animals to explain about the importance of plasma proteins

2. PROCEDURE:- This experiment was conducted in dogs. The blood is completely eliminated from the body of dog. The separation of red blood cells takes place from plasma and the separated red blood cells washed particularity in saline and re infused into the body of the same dog along with a physiological solution termed as Lockes solution. Because of thew sudden lack of proteins, shock is observed in the animal.When the fed with diet consisting of high quality of proteins in a sufficient manner, the restoration of the normal level of proteins happens particularly within seven days and the animal survives. The synthesis of new plasma proteins takes place particularly by the liver of the dog. When the experiment is conducted in animals particularly after the removal of liver, in spite of the diet consists of the quantity of proteins in an adequate manner, the plasma proteins are not produced. The shock retains in the animal and results in death So, the experimental plasmapheresis is helpful in demonstrating The value of plasma proteins for survival The synthesis of plasma proteins by the liver

3. CLINICAL SIGNIFICANCE OF PLASMAPHERESIS- THERAPEUTIC PLASMA EXCHANGE: INTRODUCTION;_ Plasmaphertesis is used as a blood Purification procedure for an effective treatment of many auto immune diseases especially for temporry period. It is also termed as therapeutic plasma exchange. In an auto immune disease, the immune system invaders the bodys own tissues with the help of antibodies. The antibodies that are protein in nature circulate especially in the bloodstream before invading the target tissues.Plasmapheresis is helpful in eliminating these antibodies from the blood PROCEDURE Fist of all venous blood is eliminated especially drom the patient and the separation of blood cells happens especially by the equipment termed as cell separator. This technique works on a principleof a centrifuge. After remobal from the body, an anti coagulant is added to stop the clotting of blood. The plasma musty be discarded after the separation of blood cells. The blood cells are returned to blood stream of the patient by mixing with a substitute fluid ( saline ) and sterilized human albumin protein

14. USES OF PLASMAPHERESIS Even though plasmapheresis is helpful in eliminating antibodies especially from the blood, it can nor stop the production of antibodies especially by the immune system of the body. That is why, it can give protection to the tissues from the antibodies for a temporary period. The patient must undergo for repeated sessions of the treatment. Plasmapheresis is an effective treatment for the following diseases for a temporary period. CHRONIC DEMYELINATING POLY NEUROPATHY :- It is a neurological disorder manifested by progressive weakness as well as impaired sensory function especially in the legs and because of the damage of the myelin sheath particularly in peripheral nerves. GUILLAIN-BARRE SYNDROME:- IT is an auto immune disease causing weakness and an abnormal sensations (like tingling) especially in the limbs and paralysis takes place. LAMBERT-EATON MYASTHENIC SYNDROME:- It is an auto immune disorder of the neuro muscular junbction. MYASTHENIA GRAVIS:-Is is an auto immune disease and it is responsible for causing muscle weakness. PARA PROTEINEMIC NEUROPATHY:- It is a disorder of peripheral nervous system because of an abnormal immuni globulin terned as paraprotein. THROMBOCYTOPENIC PURPURA:- It is a bleeding disorder.
