Uraemia is the most serious kidney disease, but it does not refer to one type of disease, but is the end-stage manifestation of renal failure caused by many kidney diseases;< /p>
Patients with this disease have complete loss of renal function, and the body is in a serious state of metabolic disorder. Most patients can only go through dialysis > to sustain life, so what is dialysis?
What are the side effects of dialysis patients?
I. What is dialysis
Clinically used dialysis methods for uremia, mainly including hemodialysis and pleural dialysis , hemodialysis usually uses the semi-permeable membrane of the dialyzer to filter the patient’s blood and dialysate, separate toxins and water, and play a therapeutic role;
applicable to emergency Chronic renal failure, acute drug or poison poisoning, renal failure before kidney transplantation or post-transplant rejection that makes the transplanted kidney inoperative, etc.
pleural dialysis uses the patient’s pleura as a Semi-permeable membrane, the dialysate is injected into the patient’s pleural cavity, and the pleura is used to filter to remove toxins and excess water.
Among them, hemodialysis is widely used to treat acute kidney injury, hypercalcemia, hypocalcemia and hyperphosphatemia caused by uremia , hypertension, anemia, severe metabolic acidosis and hyperkalemia that is not easy to correct.
Second, the side effects of dialysis
1. Risk of infection. Uremia leads to metabolic disorders in patients, making patients low immune ability and vulnerable to the invasion of external pathogens, and the process of dialysis is easy to bring external pathogens into the human body , in addition, the patients wounds are also at risk of infection, and uremia mostly uses hemodialysis, the risk of blood infection is higher, and its treatment is more difficult than other infections.
2. Symptoms of dizziness, nausea, vomiting, and cerebral edema in severe cases . The content of toxins in the blood of patients with uremia is very high, and through dialysis, the content of toxins will drop rapidly, resulting in the increase of osmotic pressure in the brain of patients, which may easily lead to adverse reactions such as dizziness, vomiting and nausea /strong>, severe cases will also cause cerebral edema, endangering the health of patients.
3. Low blood pressure or low blood sugar. Patients with uremia have higher levels of toxins and high blood viscosity in their blood, and are prone to hypertension problems, and the normal metabolism of patients is disrupted, and the hyperglycemia occurs, which requires patients to take antihypertensive and hypoglycemic drugs on time, but during dialysis, if the dose is not adjusted in time, blood toxins will drop, which will lead to hypoglycemia or Low blood pressure problems.
4. Abnormal coagulation function. Although the principle of hemodialysis is to filter blood, this process will damage some blood components, such as platelets and coagulation factors. The loss of these two substances will lead to The patient has abnormal coagulation function, causing abnormal bleeding symptoms. The initial bleeding is mild, but with the increase of the number of dialysis, the abnormal bleeding will be further aggravated, and it may cause serious >hemorrhagic shock.
From the above, we know that uremia is a serious kidney disease, harmful to the human body It is very serious. The main treatment methods are dialysis, including hemodialysis and pleural dialysis. Hemodialysis is the most common, but it has the above four kinds of side effects. Therefore, patients should pay attention to the It is easy to deal with it and prevent danger.
In addition, in daily life, patients with uremia should also follow the doctor’s advice and take related drugs on time and in appropriate amounts, such as antihypertensive drugs, erythropoietin, antihypertensive drugs Uric acid drugs, vitamins, and phosphorus binders, etc.
