Children are naturally active, and it is inevitable for them to fall and bump, while the lips, as one of the most prominent parts of the face, are easily injured. The blood supply in this area is abundant, and there is often a lot of bleeding after injury. Seeing the child's mouth full of blood makes many parents panic. Don't rush! Master the following emergency handling knowledge to help you cope calmly. The first step is to compress and stop bleeding. Immediately use a clean tissue or handkerchief, and if conditions permit, use sterile gauze to directly press on the bleeding area and continue to compress for 10 to 15 minutes. Attention! Do not frequently take it away for inspection; If blood is soaked, add new gauze on top; Maintaining stable pressure is key. The second step is to clean the wound with flowing purified water. If conditions permit, physiological saline can be chosen to gently rinse the wound to remove surface contaminants such as sand and soil. Attention! The movements must be gentle, do not rub vigorously, and ensure that the wound is clean. The third step is to preliminarily assess the condition of the wound. For superficial small wounds that only affect the surface of the skin and mucous membranes, are short in length, shallow in depth, have neat edges, and have self stopped bleeding, they usually heal on their own after cleaning. For the following serious wounds, timely medical attention is required. Penetrating the wound through the lips, both inside and outside (the outside of the mouth can be seen from the inside). Irregular wounds have uneven edges and appear torn or detached. Active bleeding cannot be effectively stopped even after compression hemostasis. There are foreign objects inside the wound, such as sand and glass shards, which are difficult to remove on their own. There is a significant soft tissue defect (a small piece of meat has fallen off) in the tissue defect wound. If the wound affects the edge of the red lip, it is recommended to perform minimally invasive suturing after debridement, otherwise scars may be left and affect the appearance. The fourth step is to seek medical attention in a timely manner. If any of the serious situations mentioned above occur, please go to the emergency department, oral and maxillofacial surgery department, or plastic surgery department of a nearby hospital for treatment as soon as possible. It is recommended to choose oral and maxillofacial surgery as the first choice, as lip trauma often accompanies dental trauma and requires professional doctors to examine and develop a comprehensive treatment plan. The faster the wound treatment, the better. If deep wounds involve nerve or vascular anastomosis treatment, it is recommended to complete the consultation within 6 hours. In short, for a child with a lip injury, calm hemostasis is the foundation, accurate judgment is the key, and timely medical treatment is the guarantee. Parents should not be overly anxious, nor should they neglect treatment due to small wounds. Professional medical treatment is the only way to avoid functional disorders and permanent aesthetic defects. ● Key points ● Don't underestimate the large amount of bleeding caused by lip trauma. The blood supply to the lips is extremely rich, and even minor abrasions may be accompanied by significant bleeding. This often makes the wound appear much more severe than it actually is, which can easily cause panic among children and parents. After significant swelling and soft tissue damage to the lips, it can quickly cause edema, leading to significant swelling of the lips and the appearance of "sausage lips". The lips, as the visual center of the lower one-third of the face, may affect the appearance if the wound does not heal properly and leaves scars. The lips are involved in pronunciation, eating, and expression, and lip movements are inevitable in daily life. Wound treatment also needs to take into account the recovery of function. (New Society)
