What to do if your baby's hand is broken and bleeding

Children are usually naughty when running and jumping. They will think of grabbing some things with their hands, and they will also touch things with their hands, which may cause their hands to be broken and bleeding if they are not careful. After the hands are broken and bleeding, you must pay attention to disinfection, because children often suck their fingers, and they often use their hands to grab things to eat, which is very likely to cause infection in the wound. Therefore, the wound must be bandaged. During this period, you must pay attention to observe and pay attention to the child's movements, and try to prevent the child from grabbing or touching the wound with his hands.

1. General principles of wound care

Good wound repair depends on reasonable treatment, the goal of which is to close the wound and complete re-epithelialization in the shortest possible time. The standard for evaluating various wound treatment methods should be the unity of healing time and healing quality.

1. Remove the irritant: If there is thermal burn or chemical burn, the burn source must be stopped immediately, and the wound should be rinsed under running water for 30 minutes to remove the irritant attached to the wound and skin surface. Each time you change the dressing, carefully remove the necrotic tissue and infectious exudate adhering to the wound surface. Be careful not to leave cotton fibers in the wound, which will become foreign matter and affect wound healing.

2. Remove necrotic tissue: Modern wound care believes that necrotic tissue should be removed as early as possible. The reason is:

① After the necrotic tissue is autolyzed and absorbed by the wound surface, it can become toxins and cause poisoning of the body.

② Necrotic tissue is rich in nutrients such as protein, and is a good culture medium for bacterial growth and reproduction, which can easily cause infection.

③ Necrotic tissue attached to the wound surface can become a source of adverse stimulation, affecting capillary reconstruction and growth, preventing granulation growth and epithelial regeneration, and thus hindering wound healing.

There are four methods to remove necrotic tissue: surgical debridement (cutting off necrotic tissue with a knife or scissors), mechanical debridement (wiping with external force and clamping necrotic tissue with tweezers), enzymatic debridement (decomposing necrotic tissue with hydrolases, subtilisin, etc.), and autolytic debridement (using occlusive dressings to intercept moisture from the wound, soften necrotic tissue, and use enzymes in the wound exudate to dissolve and liquefy necrotic tissue, which is removed when the dressing is changed).

3. Prevention and control of infection: including cleaning the wound (clean the wound with sterile saline, and the cleaning range includes 2.5cm around the wound. The ideal flushing pressure is to use a 35ml empty needle to draw saline and flush with a 19-gauge needle to reduce the number of local bacteria); strengthen nutritional support and correct hypoproteinemia; wear sterile gloves when changing dressings, use special items for special purposes, and prevent cross infection; perform wound culture once a week to monitor infection, etc.

4. Protect the wound and its surrounding tissues: Use a pressure relief pad to reduce the pressure on the wound and its surrounding tissues; maintain the local airtightness of the wound to prevent contamination by secretions and excretions; adopt a protective posture or place a protective stent, etc.

5. Provide a moist environment for wound healing: According to the size, depth, color and amount of exudate of the wound, choose appropriate occlusive dressing to apply to the wound to provide a low-oxygen and moist healing environment for wound healing.
