After dialysis uremic pruritus in patients how else?

Dialysis patients pruritus problem has existed for a long, but so far, the exact mechanism is still unclear pruritus.

Common are the following:

After dialysis patients with uremia matter how itchy skin electrolyte metabolism disorders?:

Chronic renal failure patients because phosphorus discharge reduction, repeatedly elevated phosphorus levels, serum calcium ion levels decreased, thereby stimulating PTH (parathyroid hormone) secretion and lead to secondary hyperparathyroidism. Studies have shown that secondary hyperparathyroidism can cause itchy skin, which can cause increased hypercalcemia, skin calcification and stimulate the skin mast cells to release histamine, which increased PTH is considered to be an important cause of the disease.

Currently, the common treatment methods are:

① must restrict dietary phosphorus intake (800 ~ l000 mg / d);

② According to the application of active vitamin D prescription calcium;

③ adjusted according to the appropriate doctor dialysate calcium concentration to prevent hypercalcemia;

④ under doctor's orders to take phosphate binders reduce the intestinal absorption of phosphorus;

⑤ according to your doctor regularly chosen as hemoperfusion combined with hemodialysis or HDF (HDF) therapy;

⑥ change the way scratching. Hand pat play, Qin nails. Special attention to maintaining the integrity of the arteriovenous fistula movable side arm skin to avoid infection within the fistula. If local infection, should avoid puncture and prescribed use of antibiotics such as mupirocin ointment.

⑦ parts of the skin due to the fistula often painted alcohol and adhesive plasters, long-term is likely to cause skin irritation and dry. Hi Ershu medical spreadable oils for skin care.

The quality of nitrogen metabolites retention:

The quality of nitrogen retention metabolites skin irritation and makes the sebaceous glands and sweat glands atrophy, with varying degrees of skin dryness, scaling and cause itching. Patients with ichthyosis-like skin-like appearance, skin itching, constantly scratching, and even scratch the skin and can not be relieved.

Increase the quality of nitrogen metabolites and inadequate dialysis related. Some patients because of economic reasons, dialysis twice a week, and the choice of inexpensive and low permeability of the dialyzer treatment. Some low-flux dialyzers while also repeatedly reuse. Reuse may cause increased frequency in patients with inadequate dialysis, the quality of nitrogen metabolites accumulate, aggravating the symptoms of itchy skin.

Therefore, in order to ensure that dialysis adequacy, the quality of nitrogen metabolites reduce skin irritation. We advise patients to reduce low-flux dialyzer reuse times, increase the number of dialysis. Conditions allow, can be used in flux dialyzers dialysis. Guiding patients with cold, wet towels ice relieve itching, can be treated with care when hi Ershu dry skin.

Allergies:

Chronic renal failure patients prone to allergic reactions mainly because of heparin hemodialysis tube passage plasticizer to soften and disinfect the dialyzer and a trail of ethylene oxide and other dialysis patients to stimulate the spleen, bone marrow and skin cell proliferation and hypertrophy, resulting in blood induced histamine concentration increased skin itching.

Such itching associated with allergic rash caused more to guide patients to avoid skin damage caused by hard scratching, you can use some of the cool medicated oil or coated with hi Ershu, alleviate the symptoms.
