The hazards of hemodialysis for uremia

Uremia can be said to be a very serious kidney disease, because uremia mainly refers to problems with the kidneys, which cannot completely decompose the human body's electrolytes to achieve the purpose of balancing the human body. Therefore, severe uremia requires kidney transplantation treatment. However, if there is no kidney source, hemodialysis is needed to treat uremia. Although hemodialysis has a very obvious effect on the treatment of uremia, what harm will hemodialysis cause to the human body?

What are the dangers of long-term hemodialysis for uremia? The dangers of uremia. Dialysis can prolong the patient's life, but it also has certain risks. Moreover, long-term dialysis will cause many harms to patients. It will cause dialysis complications, further atrophy of the kidneys, and ultimately loss of kidney function. What are the dangers of long-term hemodialysis?

What complications will long-term dialysis bring?

1. Long-term dialysis complications: dialysis imbalance syndrome, with an incidence rate of 3.4%-20%. The side effects of hemodialysis mainly include nausea, vomiting, irritability, etc. In severe cases, there may be convulsions, coma, and even death. No treatment is required for mild cases; for severe cases, the treatment is mainly to immediately give hypertonic solutions, such as mannitol, 50% glucose or 10 ml of 3% sodium chloride, albumin can also be infused, and sedatives and other symptomatic treatments can be used when necessary; for more serious cases, dialysis should be terminated.

2. Hypotension: One of the most common side effects of hemodialysis, with an incidence rate of 20%-40%. There are many reasons for hypotension, which mostly occurs at the beginning, middle and late stages of dialysis. The decrease in blood sugar in the later stage of dialysis is mostly caused by rapid ultrafiltration or intolerance to acetate dialysate. Treatment: Keep the patient in the head-down position and feet-up position, stop ultrafiltration, slow down the pump flow rate, administer oxygen, and quickly replenish 100-200 ml of normal saline or 20 ml of 50% glucose when necessary, infuse albumin, and treat the cause based on the etiology.

3. Dialysis use syndrome: mainly caused by the use of new dialyzers and tubes. Treatment is mainly symptomatic.

4. Pyrogenic reaction: usually not used. In case of high fever, the dialysis temperature can be lowered. Antiamines, stimulants and antipyretics can be used as appropriate.

5. Long-term dialysis complications: Muscle spasm during dialysis is one of the more common side effects of hemodialysis, with an incidence of 10%-15%. The main sites are the rectal muscles and feet, and other sites include the upper limbs and abdominal muscles. The cause of this condition is not very clear, but it may be related to tissue hypoxia, low sodium and relative insufficient circulating blood volume during dialysis. Treatment: Slow down or stop ultrafiltration, and infuse 100-200 ml of normal saline or hypertonic sugar solution and hypertonic saline.

6. Complications of long-term dialysis: Heart failure is one of the most dangerous and serious side effects of hemodialysis. In addition to symptomatic treatment, sequential dialysis or enhanced ultrafiltration should be used.

7. Complications of long-term dialysis: arrhythmia, with an incidence of about 50%, with ventricular premature beats being the most common. The causes of side effects of hemodialysis include coronary heart disease, functional failure, pericarditis, severe anemia, electrolyte and acid-base imbalance, hypoxemia, hypotension, etc. Treatment: Etiological and symptomatic treatment, but attention should be paid to the retention and toxic effects of drugs in dialysis patients.

Tip: What are the dangers of long-term hemodialysis for uremia? The dangers of uremia. Dialysis is generally not recommended when treating uremia. Dialysis not only brings a series of complications, but also makes it easy for the disease to relapse. Repeated relapse will make the condition worse. At this time, many patients will choose continuous dialysis, but continuous dialysis faces a cost issue. Moreover, continuous dialysis will cause the kidneys to gradually atrophy and become necrotic.
