Oral mucosal ulcers, also known as “mouth sores”, are superficial ulcers that occur on the oral mucosa and can range in size from rice grains to soy beans, and are round or oval in shape, with the ulcerated surface being a concave oral ulcer, surrounded by congestion, and can be painful due to irritating foods, and generally take one to two weeks to heal on their own. Oral mucosal ulcers can invade any part of the oral mucosa, preferably in the corner of the mouth, the edge of the tongue, the tongue belly, and then gradually move to the back of the mouth, such as the parapharynx and soft palate, with severe pain. Oral ulcers include infectious ulcers and non-infectious ulcers, the former are usually seen in immunocompromised, radiotherapy complications, and fungal infections; the more common daily non-infectious ulcers are caused by insufficient vitamin intake, bites, and food scratches on the oral mucosa. The pain is so pronounced that the child may suffer from poor nasal health, crying and prolonged illness. The following is a brief introduction to four can shorten the course of mouth ulcers of the magic trick. 1, Similac + multivitamin Many parents have the misconception that Similac is a medicine for children’s diarrhea, but it is not. Similac, also known as montmorillonite, whose main components are silicon oxide and alumina, has a laminar structure and non-uniform charge structure, has a strong covering effect on the oral mucosa, and by combining with mucosal proteins, it repairs the oral mucosa both qualitatively and quantitatively, and improves the defense ability of the mucosa against disease-causing factors. In addition it can also adhere bacteria and viruses to the mucosal surface and excrete them with saliva. As a coenzyme of various enzymes in the body, vitamin has an important role in promoting tissue metabolism and anti-oxidation. Parents can grind Simethicone and multivitamin tablets into noodles and blend them with glycerin to form a paste, which can be applied to children’s mouth ulcers with a cotton swab to help relieve pain and speed up the disease process. 2, benzalkonium chloride mouthwash benzalkonium chloride is a cationic surfactant, a broad-spectrum bactericide, can change the bacterial cytoplasmic membrane permeability, so that the bacterium cytoplasmic material extravasation, hinder its metabolism and kill the effect. Mucosal disinfection concentration of 0.05%, you need to buy the finished product diluted by half before use. Suitable for slightly older children to reduce the occurrence of swallowing, but a small amount of swallowing mouthwash is not a big deal. 3, oral ulcer patch oral ulcer patch is currently more commonly used in clinical treatment, which is mainly dexamethasone patch or chlorhexidine dexamethasone patch. Since glucocorticoids have anti-inflammatory and anti-allergic effects and can accelerate the speed of mucosal repair, they are more widely used in adults. However, due to the special physiological characteristics of children, they can be given sparingly and long-term treatment with glucocorticoid patches is not recommended. 4.Lidocaine gel As a local anesthetic with high safety, lidocaine excipient can be evenly attached to the mucosa and can delay the release of the drug, the absorption of the drug by the mucosal mucosa, so that the drug action time is prolonged. It also has a lubricating effect, which reduces the discomfort caused by the application of the ulcer. Parents can apply a small amount of lidocaine gel to the ulcer before the child’s meal, which can reduce the feeding difficulties caused by pain during the child’s meal. All of the above methods are easy to operate and have a satisfactory clinical effect. During the care process, we should pay attention to the oral hygiene of the child, and we need to rinse the mouth after all three meals to reduce the occurrence of ulcer infection. Parents need to consult the doctor before using the specific preparation and use method, the course of treatment and other specific matters.
