What is hemodialysis? Does dialysis mean that life begins to count down?

Hello, everyone, I am a nephrologist, and dialysis patients are the most contacted in my work. What I want to say is that dialysis does not mean that life begins to count down, because people can't live forever. If we have to compare, people will be farther away from death from the moment they are born, every hour, every day and every year.

First, what is hemodialysis?

According to my guess, the subjects may think that hemodialysis will be a very scary thing. Patients live in pain every day, but they are not. Hemodialysis patients only need to go to the dialysis center of the hospital for dialysis every week because of treatment. In fact, it is not that different from everyone's life.

(1) Dialysis mode: Get to the point, the word "hemodialysis" is actually an abbreviation, and the standard term is "hemodialysis". Of course, this is just a general statement. There are many modes, such as hemodialysis, hemofiltration, hemodiafiltration and pure ultrafiltration. According to the ability to remove toxins, it can be divided into low flux dialysis and Qualcomm dialysis; According to the dialysis time, it can be divided into intermittent hemodialysis and continuous renal replacement therapy.

(2) Dialysis principle: A complete dialysis process must have the following two things, namely dialysis machine and dialysis membrane. Don't underestimate the dialysis membrane, it can remove toxins, moisture, electrolytes and other substances in the body. According to the difference of dialysis membrane and dialysis mode, it will play a role in diffusion, convection and adsorption.

Second, life thinking about dialysis?

At this point, I think it is boring to talk too much about theory. Let me tell you a few cases of our dialysis center, leaving you to think about what dialysis life is like.

Case 1: This dialysis patient is 35 years old. He used to have a history of nephritis, and he didn't pay attention to it himself. Uremia can only be treated by dialysis, but he didn't give up his career. Before he became ill, he was a very diligent person. He opened a small workshop, bought several machines, took orders to process parts for others, and worked day and night. After dialysis, he stopped working and hired several workers. But people are no longer as absorbed as before, because he understands that no amount of money is worth more than a healthy body. Listen to the doctor after dialysis, and because I am young, there are basically no complications at present. He has been waiting in line for a transplant in the provincial hospital, and he carries his boss's bag every time he comes to dialysis. He is in good spirits and full of energy.

Case 2: This is also a male dialysis patient. At the age of 26, he was diagnosed with uremia and had a kidney transplant after dialysis for one year. However, the good times did not last long. Later, the kidney was transplanted because of lung infection, which was useless, and then he started dialysis treatment. His family condition is good, and now he is waiting for another kidney transplant. Because transplantation also requires physical conditions, such as how much heart function should be achieved and how anemia is. These are indicators that need reference, and I don't need them. Every time, he is very positive, which index needs to be rechecked, and the weight control is good, because he knows that the quality of life after transplantation is different from that after dialysis.

Case 3: This is a young woman. In her twenties, she thought it was nephritis and refused to have a kidney puncture. After a while, her kidney function deteriorated. After going to Shanghai, she still wants to have a puncture. After puncture, she thought it was IgA nephropathy. At that time, she was badly swollen and protein was low. The plan is to use hormones, and the effect is good. However, girls love beauty and think that taking hormones has great side effects, which may affect the future. At this time, the course of hormone therapy has not yet arrived. After the swelling subsided, all hormones were stopped. According to others, there is an old doctor who treats a particularly serious disease in this area. I don't know how many people lined up to see him, and then I started eating the doctor's herbs. Later, he was sent to the hospital because of heart failure (a complication of uremia). After color Doppler ultrasound, the kidney shrank, and then I started peritoneal dialysis.

Case 4, Case 6, Case 6, Case 7 and Case 8 .........

Third, summary: Everyone is a different individual, so everyone's perception of life after dialysis is different. Life will not start counting down because of your uremia dialysis. It depends on everyone's attitude towards life. Is it hesitation, expectation, regret or something? No matter who you are, you can't decide the length of your life, but you can decide the width of your life, and you can do more meaningful things in an effective life. As the saying goes, the Yan wants you to go in at midnight, who dares to leave you in the night, not living in the past or the future, but living optimistically in the present every day.

Message from the author: This is an open question. There may be many uremia patients coming in to see it. Everyone has his own attitude. Your experience is your story. Welcome everyone to express their feelings and thoughts in the comment area, so that kidney friends will no longer feel lonely.

For many diseases, the development to a certain extent will cause kidney damage, such as our common chronic kidney disease, diabetes, hypertension and so on. At the end stage, patients may have obvious anorexia, nausea and vomiting. At this time, we should be alert to whether the kidney has failed to play its normal metabolic role. When we tested, blood urea nitrogen was 28.6mmol/L, blood creatinine was 707ummol/L, and blood potassium was 6.5. In a word, hemodialysis is to filter out what our kidneys can excrete normally and maintain normal life activities. However, starting dialysis does not mean the countdown to life, and patients should actively cooperate with doctors for treatment.

Hemodialysis, referred to as hemodialysis for short, also known as artificial kidney and kidney washing in popular parlance, is a blood purification technology. Based on the principle of semi-permeable membrane, all kinds of harmful and redundant metabolic wastes and excessive electrolytes in the body are discharged from the body through diffusion and convection, thus purifying blood and correcting the balance of water, electrolyte and acid-base. At present, it is the most commonly used treatment for end-stage renal disease in China. Hemodialysis has many advantages: dialysis efficiency is high, and more toxins can be removed from the body in a short time; Accurately complete the set amount of dehydration and remove excess water in the body; The treatment is operated by medical staff, and the patient is relatively relaxed; Technology development takes a long time, and most medical units above the county level can carry it out.

How many years can life last after hemodialysis?

Theoretically speaking, as long as uremia patients have regular dialysis, constantly adjust drugs, actively treat complications, and cooperate with a nutritious diet, their life expectancy will not be significantly shortened. According to reports, in Asia, since the beginning of dialysis, patients have been constantly refreshing their life span, and now some patients have survived for more than 40 years (dialysis technology has been popularized for more than 40 years). According to the establishment of hemodialysis departments around the country, there are patients of the same age as the departments in the morning and evening. However, due to the different age, primary disease and nutritional status of patients who start dialysis, various complications will appear continuously with the increase of dialysis age, so there are great differences among individuals.

Does dialysis mean that life enters the final countdown?

Many patients with kidney disease talk about dialysis discoloration, thinking that after receiving dialysis treatment, they will completely become "disabled" and their lives will enter the final countdown. Therefore, many renal patients who have entered uremia still resolutely refuse to receive dialysis treatment.

This is of course a wrong idea!

At present, patients with kidney diseases in the world have maintained their lives through dialysis for 30 years, and many patients in China have maintained their lives for more than 10 years.

Dialysis is an alternative therapy, in which patients replace the kidneys that have lost their function and maintain the minimum physiological function of the kidneys.

Patients with renal failure should not be afraid of dialysis, and should receive dialysis treatment in time according to the advice of professional doctors.

Common dialysis methods and their advantages and disadvantages

1, hemodialysis hemodialysis can improve plasma solute composition faster and remove water in the body faster. Efficiency and convenience are its main advantages.

However, because it is intermittent, the removal of liquids and solutes must be completed in a short time every day, so the internal environment fluctuates greatly, and rapid correction of electrolytes may lead to arrhythmia. Critical patients often cannot tolerate rapid dehydration, so not all patients are suitable for hemodialysis treatment.

2. Peritoneal dialysis Peritoneal dialysis can be treated for 24 hours. This continuous feature is especially suitable for some patients with unstable hemodynamics, such as the elderly, some patients with severe diabetes and patients with poor heart function.

Peritoneal dialysis is not suitable for patients with extensive adhesion after abdominal surgery.

Of course, the choice of dialysis mode depends on the patient's specific condition, family living environment, medical environment of residence, personal hospital and professional judgment of doctors.

Patients with renal failure should incorporate dialysis into their daily lives and treat it as usual like eating, drinking and sleeping.

Dialysis technology is changing with each passing day, not only to prolong patients' lives, but to keep them living in more normal conditions.

Therefore, for a uremia patient in a relatively healthy state, there is no reason to think that he can no longer work and play, and daily life is not a problem. After regular treatment, patients' quality of life will be higher.

20 19 abstract: I am a patient with renal failure, and I am currently living on dialysis. These five years have been full of ups and downs, and it's not easy to walk all the way. No matter how much suffering you experience, tell yourself not to give up, no matter how much mental and physical pain you suffer, tell yourself to be strong, no matter what the future outcome is, tell yourself to face it calmly. Roll up your sleeves and stride forward. An optimistic life is king! Come on! To myself! # My New Year's Resolution in 2020 #

Medicine does not ask Chinese medicine and western medicine, as long as it is effective. Without dialysis technology, some people's grave grass may have grown for more than ten years. It is the right way to learn from each other's strengths.

Invited to answer questions: people think that dialysis is the countdown to life, but in fact birth is the countdown to life. It's just a matter of time. If a person's kidney is broken, how long can he live? The two choices of western medicine are dialysis, and Chinese medicine treatment is taking Chinese medicine, which can prolong life. What kind of treatment is better?

Some people choose to take traditional Chinese medicine when renal function is not complete, but it is a three-point poison. Combined with several years' diet, it is found that TCM conditioning can only maintain the status quo and cannot cure chronic renal failure of nephropathy. Chinese medicine plus diet conditioning, the patients who have tasted it just describe suffering without reading words.

If you choose dialysis treatment, people here have described it for more than ten years. Dialysis is like eating, and it smells good after eating. Before dialysis, the patient is the most effective. Most people choose dialysis, dialysis is the starting point of life!

Speaking of the countdown to life, human life has entered the countdown since the day of birth. No one can predict when he will die, nor can hemodialysis patients, nor can doctors judge when he will die. Since normal people and hemodialysis patients don't know when they will die, why not live well, don't think about when they will die all day, and be open-minded and cheerful is the best anti-disease medicine. Some people are seriously ill, and there was hope for cure. Or you can go on living, and as a result, your heart can't get through that hurdle. Every day, you are sad and scared. As a result, your illness didn't kill you. You scared yourself to death. I have been on hemodialysis for almost three years. I've been building for three years, and there are some normal people around me who died because of other sudden diseases and accidents. How can I predict people's life span? Man's life is decided by heaven. If God wants you to die, you have to die. If God doesn't want you to die, even if you have experienced car accidents, accidents, natural disasters and man-made disasters, you can't die. Therefore, those of us who can survive, we should put down our mentality, live well, don't think about when we will die, face every day happily, and believe that the future will be better.

My experience is that it is right to find a junior high school student with rich clinical experience in the early, middle and late stages of nephropathy! Just find the right Chinese medicine and use the right Chinese medicine. The therapeutic effect is stronger than that of western medicine. I met a patient who was treated in the College of Traditional Chinese Medicine. At the time of initial diagnosis, the blood muscle and liver were as high as 780. It's uremia Young and middle-aged doctors have asked you for dialysis, and patients are unwilling. Finally, they found a retired expert in our hospital and prescribed oral Chinese medicine plus enema. After two years, the patient's serum creatinine dropped to more than 300, and all the detection indexes were better than hemodialysis. I still insist on taking Chinese medicine.

This sentence is wrong, as long as people are alive, it is a countdown.
