Question 2: What is the function of blood purification? Blood purification is also called blood perspective analysis.
1, the function of hemodialysis is to drain the blood in the body to the outside, remove the metabolic waste in the body through material exchange, and maintain the electrolyte and acid-base balance in the body;
2. Hemodialysis is used for patients with renal failure who can't get rid of wastes in the body. The benefits are far from mentioned. This is the last resort.
Question 3: What are the types of blood purification? Blood purification is a commonly used alternative treatment method in modern medicine. There are mainly the following types: hemodialysis, hemofiltration, continuous arteriovenous hemofiltration, hemoperfusion, immunoadsorption, plasma exchange and peritoneal dialysis. 1. Hemodialysis is to introduce blood into the dialyzer, and use the difference of solute concentration on both sides of the semi-permeable membrane to remove metabolites and toxic substances through osmosis, diffusion and ultrafiltration, and correct the imbalance of water and electrolyte. Adapted from 1. Acute renal failure; 2. Chronic renal failure; 3. Acute poisoning. There is no absolute contraindication to hemodialysis, but dialysis should be avoided as far as possible in the following situations to avoid accidents: shock or hypotension, uncontrollable bleeding, obvious enlargement of the heart with serious myocardial damage and serious arrhythmia. Uncontrolled severe diabetes, cerebral hemorrhage and elderly patients. Second, hemofiltration is a simulation device designed according to glomerular filtration function. Its main features are: 1. The removal of small molecular substances such as urea nitrogen and creatinine is slightly inferior to hemodialysis, but the removal of medium molecular substances, the correction of water, electrolyte and acidosis, and the treatment of pulmonary edema, pericarditis and brain edema are better than hemodialysis. 2. It can obviously improve anemia and triglyceride, and make hypertension easy to control. 3. The combination of hemodialysis and filtration is called hemodialysis filtration, which can improve the efficiency of blood purification and shorten the dialysis time. 4. The disadvantage is that a large amount of replacement fluid is input, which is easy to be polluted, causing fever and septicemia. Third, continuous arteriovenous hemofiltration is to use the normal pressure gradient difference of arteriovenous pressure to make blood pass through a small filter continuously to achieve the effect of hemofiltration. Its characteristics are: low filtration rate, no need to use blood filter and supplement a lot of replacement liquid. It is especially suitable for field rescue of acute renal failure. Fourthly, hemoperfusion is to introduce the arterial blood of the patient into a hemoperfusion device with adsorption materials, so that the poisons and metabolites in the blood can be adsorbed and purified by contact with the blood, and then re-input into the body. Hemoperfusion can effectively remove creatinine, uric acid, middle molecular substances, phenols, guanidines, indole, organic acids and many drugs in blood, but it can't remove water and electrolytes. Therefore, when treating uremia, hemodialysis or hemofiltration should generally be combined. 5. Immunoadsorption is a new technology developed in recent twenty years. It combines highly specific antigens, antibodies or some substances (ligands) with adsorption materials (carriers) to make adsorbents (columns), and uses its specific adsorption performance to selectively or relatively specifically remove endogenous pathogenic factors from patients' blood, thus achieving the purpose of purifying blood and relieving illness. Mainly used for the following diseases: 1, severe systemic lupus erythematosus. 2. Primary and recurrent focal segmental glomerulosclerosis. 3. Antineutrophil cytoplasmic antibody associated vasculitis. 4. Nervous system diseases: There are anti-acetylcholine receptor antibodies in the serum of patients with myasthenia gravis, which interfere with neuromuscular transmission and lead to myasthenia gravis. Immunoadsorption can remove antibodies and quickly improve the symptoms of myasthenia gravis. 5. Dilated cardiomyopathy: Many different autoantibodies have been detected in patients with dilated cardiomyopathy: myocardial myosin antibody, muscarinic M2 receptor antibody, mitochondrial aconitic acid water and enzyme antibody. 6. It can be used to treat various autoimmune diseases, such as anti-glomerular basement membrane disease, lipoprotein nephropathy, Wegener granuloma, type II cryoglobulinemia, rheumatoid arthritis, immune thrombocytopenic purpura, hemolytic uremic syndrome/thrombotic thrombocytopenic purpura (HUS/TTP), coagulation abnormality mediated by anticoagulant antibody, etc. 6. Plasma exchange is to introduce the patient's blood into the plasma exchange device, discard the separated plasma, and replenish a certain amount of plasma to remove antibodies in the patient's plasma and activate immune reaction media and immune complexes. Mainly suitable for: ① immune complex glomerulonephritis and anti-glomerular basement membrane glomerulonephritis, such as pulmonary hemorrhage-nephritis syndrome. Rheumatic diseases and systemic lupus erythematosus. Nodular periarteritis and rheumatoid arthritis. ③ Autoimmune hemolytic anemia, hemolytic uremic syndrome and thrombotic thrombocytopenic purpura. ④ Myasthenia gravis and Guillain-Barre syndrome. ⑤ Liver coma. 6 poisonous mushrooms are poisoned. ⑦ Severe psoriasis. 8. Acute rejection after renal transplantation. Pet-name ruby hyperlipidemia. Seven, peritoneal dialysis is the use of peritoneum as a semi-permeable membrane, according to the principle of Donan membrane balance, the prepared dialysate is injected into the peritoneal cavity of patients through a catheter, and through the concentration gradient difference of solute on both sides of peritoneum, the purpose of eliminating metabolites and toxic substances in the body and correcting the imbalance of water and electrolyte is achieved.

Question 4: Excuse me! Can you get sick if you eat too much vitamin C? It shouldn't be digested and excreted (why does this problem take so long ...)
Question 5: What are the drugs for blood purification? Giant algae
Colloidal components in kelp can promote the excretion of radioactive substances in the body with urine, thus reducing the accumulation of radioactive substances in the body.
mung bean soup
Mung beans are cold, which can clear away heat and toxic materials and dispel fire. It is a good drink in China in summer and autumn. Regular drinking helps to expel toxins from the body and promote normal metabolism. Mung bean is a traditional Chinese medicine commonly used to solve many kinds of food or drug poisoning.
carrot
It can combine with heavy metal mercury to generate new substances and excrete them.
garlic
The special ingredients in garlic can reduce the lead concentration in the body.
mushroom
Can help expel toxins from the body and promote normal metabolism.
Some fruits can also help you cleanse your intestines and detoxify. Different fruits have different poisons.
strawberry
Detoxification fruit that can't be ignored is low in calories and contains vitamin C. In natural therapy, strawberries can be used to clean the gastrointestinal tract and strengthen the liver. However, people who are allergic to aspirin and have poor gastrointestinal function should not eat it.
cherry
Precious natural medicine and food. Cherry pulp can remove toxins and unclean body fluids, so it has a considerable auxiliary effect on kidney detoxification and a mild laxative effect. When selecting, it is best to choose cherries with full and solid fruits and green stems.
grape
Dark purple grapes can be eaten almost all year round, and also have the effect of detoxification. It can help the composition of intestinal mucus, and help the liver, intestine, stomach and kidney to clear the garbage in the body. The only small drawback is that the calories are a little high, and 40 grapes are equivalent to 2 apples.
apple
If you are afraid of being fat, apples are a good choice. In addition to rich dietary fiber, galacturonic acid contained in it is very helpful for detoxification, while pectin can prevent food from rotting in the intestine. When choosing apples, don't forget to change apple varieties of different colors frequently, and the effect is better.
Fresh fruit and vegetable juice is a "cleaner" in the body.
Drinking fresh fruit and vegetable juice often can dissolve toxins accumulated in cells, neutralize acidic toxins in the body, purify internal organs and balance neutral physique.
Foods rich in cellulose or chlorophyll have detoxification function, and eating more helps to eliminate toxic substances accumulated in the body. Before toxic substances are excreted by the liver and absorbed by the small intestine, toxic substances can attach to fibrous food and chlorophyll, and can be excreted through feces, which can feed into the cumulative effect of toxic substances. The foods that have such effects are: rice bran, spinach and radish leaves in turn. However, fiber food is easy to excrete nutrients from the body while detoxifying, so it is not suitable for growing children or people who are recovering from illness.
Ordinary people can eat diuretic and heat-clearing foods, such as Sydney, watermelon and orange, or choose sesame paste, almond paste and other laxative foods.
Question 6: What is the function of hemodialysis? Hemodialysis means that some waste in blood is removed through a semi-permeable membrane. Hemodialysis is a safe, simple and widely used blood purification method. Dialysis refers to the movement of solute from high concentration solution to low concentration through semi-permeable membrane.
