There are a lot of dialysis patients would ask: why after dialysis, feel itchy skin, and it is hard to tolerate for them.
The incidence of general itchy skin is 60% - 90%. As the dialysis time extended, symptoms gradually worsened, make patient anxiety all day long, very painful, bad affect the patient's quality of life.
A, Electrolyte metabolic disorders cause itchy skin
For patients with chronic renal failure is the most common that due to phosphorus reduction, blood phosphorus levels rise repeatedly, calcium ions in the blood levels drop, so as to stimulate the secretion of parathyroid hormone and cause secondary hyperparathyroidism.
Solution:Limit the intake of dietary phosphorus, it is recommended that the phosphorus content of less than 600-1200 mg/d best, avoid eating soy products and animal innards.
Application of active vitamin D and calcium. Adjust the dialysate to appropriate calcium concentration, to prevent the hypercalcemia.
Change the way scratching. With handle gently pat, frequently your nails. Special help maintain arteriovenous fistula in the integrity of the skin -- on the arms, lest cause internal fistula infection.
If the local people, should be to avoid piercing, and with the multinational antibiotic ointment in accordance with the doctor's advice.
Second, nitrogen retention mass metabolites cause itchy skin
Nitrogen retention mass metabolites on the stimulation of the skin and make the sebaceous glands and sweat gland atrophy, make the skin appear different degree of dry, desquamation and cause itching.
Skin looks like ichthyosis, itchy skin, often scratching, even catch broken skin and cannot be alleviated.
Is the main cause of nitrogen metabolism retention: inadequate dialysis, chose low flux dialysis machine for repeated use.
Reduce the repeated use of low flux dialyzer, increase the number of dialysis (3 times per week), conditions allow, can choose the flux of dialyser on dialysis.
Care to standardize operation, pay attention to when performing a treatment aseptic operation, ensure safety during dialysis treatment.
Patients with cold water and ice towels wet apply relieve itching, dry skin can besmear outside skin lubricants and use the cheese of soap.
Three, allergic reactions cause itchy skin
Allergic reaction mainly because heparin, softening vascular access plasticizer,sterilized dialyser and crowd epoxy ethane can stimulate the dialysis patients with spleen, bone marrow and the skin mast cells proliferation and lead to increased blood concentrations of histamine and induce the skin itching.
1. The use of histamine drugs treatment
2. Encourage comfort patients, alleviate patients' tension
3. Choose the dialyzer with good biocompatibility, in order to reduce allergic reaction caused by ethylene oxide.
4. Dialysis can choose saline before fully piercing dialyser reuse and pipeline, the machine completes the residual disinfectant detection, ensure the safety of the dialysis treatment.
5. This kind of allergic reaction of itch rash, guide the patients to avoid scratching damage to skin and hard to use some of the cool and refreshing drug daub, relieve symptoms.
