Read The Flame within a guide to prevent & treat autoimmune diseases by Dr Imran Khan Plasma Exchange This information is written especially for patients like yourself who may be exposed to plasmaExchange as a treatment option. Use this information to help set a framework of assisting you with your discussions with your the medical providers to help you understand this safe, simple, and routine procedure and what it will involve. Please discuss the information below with your health care providers. The following four questions will be answered: 1. What is plasma? 2. What is plasma exchange? 3. Why is plasma exchange necessary? 4. What actually happens during a plasma exchange procedure? What is Plasma? Plasma is the fluid portion of the blood that allows the circulation of red blood cells, white blood cells, and platelets. It consists mainly of water in which numerous compounds are dissolved. Plasma also makes possible chemical communication among different parts of the body by carrying minerals, hormones, vitamins, and antibodies. Normal plasma has a yellow color when it is observed through a test tube or bag where blood has settled. What is Plasma Exchange? Plasma Exchange is a patient procedure involving the separation and removal of the plasma from the blood in order to remove a disease substance circulating in the plasma. The red blood cells, white blood cells, and platelets are returned to the patient, along with a prescribed replacement fluid. Simply stated, the “old plasma” is removed and replaced by the “new plasma.” In other words, a PLASMA EXCHANGE took place. Why is Plasma Exchange Necessary? Some diseases create substances which circulate throughout the body in the plasma portion of the blood and which may attack healthy cells or tissue. These substances are created by a mix-up in the body’s immune system. Other diseases cause an overproduction of the substances which results in slowing down the blood flow (in the same way that thick liquids move more slowly than thin ones). A physician will decide if it is desirable to remove a large quantity of the substances with a plasma exchange so that the accompanying medication is more effective in controlling the disease. The plasma is replaced with donated fresh frozen plasma or, more commonly, physiologically acceptable replacement fluids, such as a mixture of albumin and normal saline. What actually happens during a Plasma Exchange Procedure? Plasma exchange is accomplished with a medical device called a blood cell separator; the COBE® Spectra™ Apheresis System is such a device. It uses a centrifuge to separate plasma from cellular blood components. Qualified medical personnel operate the blood cell separator and monitor the condition of the patient at all times. Blood is drawn from a patient’s arm vein by a needle which is attached to a blood tubing set. Anticoagulant is added to the blood to keep it from clotting. The blood and anticoagulant enter the compartment of the blood cell separator where the plasma is separated from the cellular components and pumped into a collection bag. The cellular components are drawn from the compartment and a replacement fluid prescribed by the physician is added to replace the volume of plasma which is removed. The mix of cellular components and replacement fluid is returned to the patient, through a needle in the other arm. The blood cell separators accomplish all the above steps in an automated, continuous, and safe manner. Other Frequently Asked Questions (please contact your physician for more detailed medical information) Q. Are there any side-effects of this procedure? A. The initial insertion of the needles may cause some discomfort. The needles have to remain in place during the procedure (about two to four hours). Keeping the arms in one position and staying relatively still may be uncomfortable. Sometimes it is not possible to achieve adequate blood flow from arm veins. Therefore, a catheter needs to be placed which involves minor surgery. Although the blood cell separators remove only a small portion of blood from the patient at any one time, the changes in blood volume or the type of replacement fluid utilized may make some patients feel dizzy or light-headed. Patients should immediately tell the medical staff if they begin to feel uncomfortable. The anticoagulant used to keep the blood from clotting and certain types of replacement fluids might cause a patient to notice a sour taste in the mouth, tingling around the lips, or sharp pains, like pins being stuck in the fingers or toes. Patients should immediately tell the medical staff if they have any of these symptoms. Q. Is Plasma Exchange a safe medical procedure? A. Approximately 300,000 plasma exchange procedures are performed worldwide each year with few problems. Another one million procedures, which are similar to plasma exchange, are performed each year on volunteer donors to collect plasma and platelets, again with few problems. Q. Are there any reactions or lasting side effects? A. Some patients feel tired after a plasma exchange procedure and require rest. Side effects during the procedure might include feeling dizzy, light-headed, nauseated, and cold. Some patients may feel tingling in the fingers and around the mouth. It is extremely important for patients to notify the medical staff immediately if they feel these symptoms or feel uncomfortable. The medical staff can slow down or stop the procedure for a short time before deciding whether to continue. Q. How long does a Plasma Exchange take? A. This varies from patient to patient and with the type of blood cell separator utilized. The blood cell separators usually perform a plasma exchange in approximately two hours. Q. Are patients left on their own? A. No. The medical staff will be there all the time. A physician generally examines a patient before the procedure begins and is available nearby throughout the procedure. Q. How often do Plasma Exchanges need to be performed? A. The number of plasma exchanges varies, according to the disease treated and patient response. The physician monitors the clinical response and determines the necessary number and frequency of plasma exchanges to be performed. Q. Can patients catch a disease from the supplies being used? A. No. The blood tubing set and needles are sterile, used only one time, and then discarded. Anticoagulant, normal saline, and albumin replacement fluid are also sterile solutions. There is some risk of disease transmission when fresh frozen plasma is used as a replacement fluid. Q. Can a patient have something to eat or drink during a procedure? A. There’s generally no reason why most patients can’t eat or drink during the procedure. A patient should drink some fluids and use the bathroom before the procedure begins. Q. Can a patient have visitors? A. Once the procedure is under way, you are usually allowed visitors. If there are any other questions you would like to have answered, ask the medical staff or physician.
