Plasma replacement is a method of removing large molecules from the body. Different diseases have different disease-causing substances, so the maintenance time of plasma replacement varies from a few times to ten years.
Plasma exchange is a common extracorporeal blood purification therapy, which mainly draws the patient’s blood out of the body, separates the plasma and cellular components, and replaces the patient’s original plasma with fresh plasma, albumin solution, and balanced fluid, and then transfuses it back to the patient’s body at the same speed, so as to remove the disease-causing substances contained in the original plasma.
Generally speaking, plasma replacement is done every other day, five or six times in total, in about two weeks. For different diseases, the frequency is also different. For renal diseases, it is usually done when the antibody is negative, and if there is no clear antibody test, it is judged by the clinical manifestations, and the maintenance time of plasma exchange is also different, less than half a year, and more than ten years.
Plasma replacement should be operated by professional doctors, and the discomfort should be diagnosed and treated in time, and the duration of plasma replacement varies depending on the disease.
