How to treat skin itching in patients with renal failure?

In patients with chronic renal failure, due to endocrine dysfunction caused by nitrogen retention and renal excretion dysfunction, calcium is deposited under the skin and secondary hyperparathyroidism occurs, and skin itching often occurs without obvious skin lesions. Itching at night is often obvious, affecting patients' rest, and some patients are very painful for it. Patients with advanced chronic renal failure are prone to bedsore due to long-term bed pressure, which leads to neurotrophic disorder and blood circulation disorder, persistent ischemia of local soft tissues and malnutrition. Good skin care is the key to prevent bedsore. Therefore, the patient's posture should be changed frequently during nursing, generally turning over every 2 ~ 3 hours 1 time. When turning over, you should avoid dragging, pulling, pushing and other actions to avoid scratching your skin. The bed should be kept flat, wrinkle-free, clean, dry and free of sundries. Especially keep your skin clean and dry. Patients with chronic renal failure should often take a bath with hot water, wipe their backs and massage locally to promote local blood circulation and prevent bedsores. If patients with renal failure have bedsores, the prevention and treatment of skin infections are particularly important. Local irradiation can be supplemented by infrared rays or vertical lamps to dry the wound surface, promote blood circulation and maintain the healthy growth of granulation tissue on the wound surface. During the irradiation, observe the local conditions at any time to prevent burns.
