CRRT is the short form for continuous renal replacement therapy. It is also called CBP, namely continue blood purification. It is a kind of continuous blood purification therapy for damaged kidney which has to last for 24 hours or near 24 hours per day.
In 1995, on the first International CRRT Academia Conference in San Diego, USA, CRRT was defined as all kinds of blood purification technology that can eliminate solute as well as support organ function. During the Second World War, scientists in Canada researched out the first artificial kidney machine which was first used to treat renal failure in 1946. Since then, the technology of blood purification developed very fast. Blood purification means using purification machine outside of body to filtrate pathogenic factor out in order to achieve the goal of treating the disease. It mainly includes blood dialysis, blood filtration, hemodiafiltration, blood perfusion, plasma exchange as well as Immunoadsorption and peritoneal dialysis, etc. Presently, blood purification therapy is not only used to treat acute or chronic renal failure, but also widely used to save patients who are in critical illness condition.
The clinical purpose of applying CRRT is aiming to eliminate excessive water, metabolic waste and toxin as well as adjust electrolyte disorder and support enough nutrition, which is beneficial to recover kidney function and remove kinds of inflammatory factors. Normally, CRRT is mainly used to treat acute or chronic renal failure complicated by cardiovascular function disorder, hypermetabolism or encephaledema. Besides, it can also be used to treat MODS (multiple organ dysfunction syndrome), ARDS (Acute respiratory distress syndrome), crush syndrome, ANP (acute necrotizing pancreatitis), chronic heart failure, hepatic encephalopathy as well as drug poisoning and toxin poisoning, etc.

Some Frequent Questions about Dialysis
When talking about dialysis, patients and also patients’ family member always feel scared because they all think dialysis means that the disease has got into an irreversible stage and no other treatment can be helpful for patients in this stage. What’s worse, they also think when patients begin to have dialysis, they have to accept dialysis for their whole life and only kidney transplant can be chosen finally. Is these true? We have to say this is also true even though most of the time dialysis means the severity of the disease. In order to have a more general idea on dialysis, an expert on dialysis expressed his own opinion on some points of dialysis.
Q: Is it dialysis necessary for patients who have end stage renal failure? Why they need dialysis?
A: not all renal failure patients need dialysis. When the disease progress further, patients will have anuria, anemia, vomiting, heart failure, and difficulty in lying down or other serious symptoms. Kidneys are easy to get further damage. As a result, more and more toxin and metabolic waste will accumulate in body, causing damage to other internal organs. If patients do not have dialysis in time under such condition, high-toxin in body will threaten to patients’ life. Therefore, timely and scientific dialysis is necessary for patients who are in end stage renal failure in order to get more time for the doctors to find other effective treatment methods to improve kidney condition.
Q: Why so many patients can not stop dialysis in their future life once they begin to accept dialysis?
A: For most patients, dialysis can not be stopped once it is begun. What’s worse, the frequency of dialysis is also increasing gradually, just like opiophagy. Why? This is because the former treatment is not systemic or comprehensive. Most renal failure patients said that dialysis is the only method that their doctors offered them when their disease progress into end stage. No other treatment for kidney is taken, which is the reason why dialysis can not be stopped. For most patients who are in end stage renal failure, they must know clearly that dialysis is used to save life not to treat the disease. Long-term dialysis can not repair kidney. Instead, it will make remained kidney function declined gradually. When all kidney function has lost, patients have to use dialysis to do all the work that should be done by kidney, and then they will need more and more dialysis. Therefore, when patients are having dialysis, cooperative treatment is also necessary in order to improve kidney condition. Talking about the treatment, the treatment should start from repairing renal intrinsic cells. Once remained kidney function can be protected and repaired effectively, kidneys can play filtrating function better, and then dialysis can be delayed and some patients can also have the chance to get rid of dialysis.
Q: Why patients will have less urine when they are having dialysis?
A: Generally speaking, the change of urine volume during dialysis can be divided into four periods which refer to progressive period, oliguria period, recover period and diuretic period. Normally, there is 4000ml blood in body. If patients drink 1000ml water per day, but only discharge 200ml. More water will be kept in body and permeate into blood vessel gradually. Under such condition, there will be 4800ml blood in body. This is only for one day. How about one week? When blood vessel can not burden, these blood will enter to heart gradually, which will also burden heart, causing heart failure. When patients are having dialysis, their urine will be always affected more or less, but in this stage, the change of urine volume is in order to protect heart function. If heart function is normal, urine volume can also recover to normal level. However, if less urine volume is caused by the disease not dialysis, effective and positive treatment is necessary. What’s more, even in the period of diuretic period, both patients and doctors also need to make sure that it is normal physical urine or false urine because sometimes diuresis can also increase urine volume, but when patients stop medication, urine volume will reduce again.
Q: Is it OK if the body weight reduces greatly during dialysis? Is there any problem?
A: It is true that during dialysis patients’ body weight will decrease, but this does not means the more decrease, the better. Generally, the change of body weight between two dialysis should be controlled at the level of around 1.5kg. If the change is out of this range, it may bring more damage to heart, kidney or liver. Therefore, patients should not have dialysis with the pure purpose of discharging toxin, but with no plan. A scientific dialysis is very important.
Q: When dialysis will have less meaning for patients who are having end stage renal failure?
A: Normally, the function of dialysis will be limited when patients have the following condition. The size of kidney is smaller than 5cm; patients have serious anemia which means Erythropoietin is not enough to relieve anemia; blood pressure is higher than 230; patients have had no urine for more than 9 months; patient have serious electrolyte disorder and potassium is higher than 8.0 but no treatment is effective to reduce the level of potassium. However, the above condition is also not so definite. For example, a patient who has had no urine for 10 month, he still get a relative good effect, which means there is still hope for such patients if we can find a correct method for kidney. However, such successful care is really seen. Therefore, an early treatment is important for patients who have kidney disease.
Besides, this expert also pointed out that some patients only see the change of the test results, which may also mislead them during the treatment because when treating the disease, we should focus not only on the test results, but also the root of the disease that is the kidney condition. Some patients always have repeated illness condition, which is mainly because the root cause, kidney damage, is not solved. Therefore, during the treatment of kidney disease, no matter Chinese medicine treatment or Western medicine treatment, both of them should start with repairing kidney so that the disease can be treated more effective and fundamentally.
Based on the above, is there any other treatment can be chosen during dialysis. Expert mentioned that Micro-Chinese Medicine will be a good choice for patients who are having kidney disease. This therapy has combined both Chinese Medicine and Western medicine. It can not only treat the symptoms, but also can repair damaged renal intrinsic cells. When western medicine is relieving related symptoms, Chinese Medicine can play a better effect on repairing kidney. Besides, this therapy is used in an external application method, which makes the prescription more effective and safe.

Is Dialysis Enough for End Stage Kidney Disease Patients?
Dialysis is the most common treatment for end stage kidney disease patients and patients usually feels much better after dialysis because dialysis can remove the deposited toxin and metabolic waste out of body. For this reason, most patients consider dialysis is an effective treatment for kidney disease. However, is only dialysis enough to treat kidney disease and prolong patients’ life?
First, it is necessary to know how dialysis works. Normally, dialysis is also called artificial kidney because it can take the place of kidney and play the same function as kidney so that toxin and metabolic waste can be filtrated out of body in time. In another word, when doing dialysis, it was the dialysis machines that work but not the kidney. This is also the reason why patients need to take dialysis regularly once they begin to have dialysis if no other treatment is taken at the same time. During the period of dialysis, if no treatment is taken for kidney, damaged kidney will maintained its damaged condition, and as a result it still can not work normally. When patients stop dialysis, toxin and metabolic waste will accumulate in body again and when the toxin and metabolic waste accumulate to a certain degree, dialysis is needed again. However, dialysis is only a kind of replacing treatment. It is still different from real kidney, even though it plays the same function as kidneys. Day by day, patients may have many discomforts caused by dialysis and even sometimes patients will become weaker and weaker. Therefore, only dialysis is not enough to improve patients’ living quality and prolong patients’ life. Only a treatment that can treat the kidney can makes people live a better and better life.
Since dialysis machines do not work on kidney, it is necessary to choose a treatment that can treat the kidney when patients begin to take dialysis or even before patients begin to take dialysis. Only in this way, kidney condition can be better and kidney function can be improved. As a result, patients who are in end stage kidney disease can have the possibility to avoid or even get rid of dialysis, and finally patients can live a normal life. In one word, dialysis is only a treatment for short time, but not for life time.

A Correct Attitude to Dialysis
Kidney disease is always considered as the second cancer because it can be treated but can not be cured. Different from cancer, when patients are in end stage kidney disease, they can choose dialysis to help kidneys to discharge toxin and metabolic waste out of body which method is also called artificial kidney. However, what is the function of dialysis or is it helpful? Actually, in order to know the answers, we need to have a correct attitude to dialysis.
Advantages of Dialysis
Most of patients are forced to choose dialysis when their condition is too serious and some patients who have better financial condition may also choose kidney transplant directly instead of dialysis. However, is dialysis so terrible? Actually, dialysis still has its own advantages in treating kidney disease. The same as other medicines for kidney disease patients, dialysis is only a method to relieve the disease. What’s more, choosing a proper time to take dialysis for patients is also helpful for them to live a better life and get a better treatment in the future.
It is well known than when patients’ illness condition get into end stage renal failure, patients will always have the symptoms of nausea, vomiting, skin itch, spasm, bad smell in mouth and so on, and all these symptoms are caused by high toxin deposite in body which leads to functional disorder. Under such condition, dialysis can help damaged kidney to discharge the deposited toxin such as urea, creatinine and so on out of body. Besides, dialysis can also remove extra water in body, which can prevent high blood pressure, Ventricle Enlargement as well as cardiac damage or even heart failure, etc.
What’s more, an earlier dialysis is also helpful to protect remained kidney function, which can provide a beneficial kidney internal environment for future treatment. Therefore, in some cases, dialysis is necessary in order to relieve kinds of symptoms and complications, playing an important role in saving patients life.
Disadvantages of dialysis
It is obvious that dialysis has many advantages in treating kidney disease and saving patients life. However, this is only a temporary treatment and patients should also think about the harms that dialysis may bring when it relieves kinds of discomforts.
1. There are also many complications of dialysis. Dialysis is used to save life, but not used to treat the disease. Proper dialysis can discharge toxin and metabolic waste out of body in time. However, the complications of dialysis is also various and serious, such as low blood pressure, muscle cramp, abdominal pain, bleeding or even heart problem and so on. From another viewpoint, dialysis will make patients become weaker and weaker.
2. Kidney function will keep declining and weakening gradually if patients take dialysis for a long period. Dialysis is only taking the place of the kidney to discharge toxin out of body, but it does not treat the kidney. If patients depend on dialysis for a long time, remained kidney function will declines gradually because kidney never work by itself during dialysis period. Day by day, all kidney function will disappear and finally kidney transplant will be the only way for kidney disease patients.
3. Living quality may become lower after patients take dialysis and sometimes dialysis may also make patients lose the best treatment opportunity. When the disease gets into end stage, patients will lose the chance to choose the treatment by themselves. At this moment, it was the illness condition that chooses treatment because kidney has been damaged too seriously and dialysis is necessary to maintain patients’ life. However, dialysis can affect patients’ normal life and it will make patients weaker. Most of the time, it may also reduce the life expectancy of kidney disease patients. Therefore, kidney disease patients are suggested to consider about other kind of treatment other than dialysis when they just begin to accept dialysis. According to present medicine technology, Chinese medicine treatment combined with western medicine treatment is a better choice, which can delay dialysis interval and reduce dialysis times gradually.
Considering about the above points about dialysis, patient with end stage renal failure should have a comprehensive analysis on their own illness condition when local hospitals all suggest dialysis. Kidney disease experts also pointed out that when taking dialysis, patients should also choose treatment that can treat the disease starting with repairing and protecting kidney. Only in this way, patients can have the possibility of getting rid of dialysis, which can not only take full use of dialysis advantages, but also avoid the side effects from dialysis in future life.
