After a bedsore breaks down, the wound should be protected from infection, cleared as soon as possible and treated symptomatically at the hospital. Decubitus ulcers, or pressure sores, are localized pressure on the body that leads to impaired blood circulation, causing blisters, ulcers or gangrene in the skin and subcutaneous tissues due to ischemia. When the breakage is visible to the naked eye and is serious, it can be treated in the following ways: 1. This can lead to life-threatening sepsis. Furacilin or hydrogen oxide and other drugs can be used to rinse the wound surface by a certain proportion of the configuration of the solution to avoid infection; 2, drug therapy: analgesic drugs can choose non-steroidal anti-inflammatory drugs such as ibuprofen to relieve pain. Antibiotics should be selected for the pathogenic bacteria of the infection, commonly tetracycline, metronidazole, etc. Supplemental growth factors can promote the recovery of skin ulcer defects. Topical dressing can choose transparent film, hydrocolloid, antibiotic dressing, etc. to avoid trauma infection and absorb exudate; 3. Physical therapy: Oxygen therapy can use pure oxygen to inhibit the growth of trauma anaerobic bacteria, improve the supply of oxygen in trauma tissue, improve local tissue metabolism, and promote trauma recovery; 4. Surgical treatment: ulceration and necrosis occur at the lesion site, and necrotic tissue can be removed by ultrasound, high-pressure water jet, etc. to promote skin healing. If the necrosis area is large and the risk of infection is high, the healthy skin and tissues can be implanted in the nearby lesion area to promote healing. All of the above actions should be performed according to medical advice and should not be done on your own. In the initial stage of pressure sores, helping patients to turn regularly to observe the skin condition, massaging the pressurized skin, and using an air mattress can prevent pressure sores from worsening. Patients should eat a diet rich in calories, protein, water, vitamins and minerals to enhance nutrition, which can prevent pressure sores and also promote recovery.
