Children snoring with white foam in their sleep is mainly related to diseases such as nasal stenosis, airway blockage, respiratory inflammation, indigestion, and obesity. However, it may also be caused by non-disease factors such as sleep quality, but generally be alert to the effects of disease. The main causes and treatment methods a. Non-disease factors of poor sleep quality and poor sleep posture in children will show such performance. For example, when sleeping on the back, the root of the tongue falls backward by the force, the inspiratory channel is blocked, and the airflow enters through the non-oral part, driving the surrounding mucous membrane or muscle vibration, causing the infant to emit a snoring sound and spit white foam because saliva has not been swallowed. It is recommended to adjust the sleeping position and take side sleep to observe if it improves. Second, disease factors 1, nasal stenosis: children’s nasal cavity is narrow, the pharyngeal cavity is relatively short, when the inflammatory stimulation leads to congestion and swelling of the mucosa of the nasal cavity. The nasal secretions blocking the nostrils, when sleeping reflux to the mouth, it is easy to cause children to sleep spitting white foam snoring phenomenon, parents can use saline to the child under the guidance of the doctor to rinse the nasal cavity; 2, airway obstruction: adenoids, tonsil hypertrophy lead to airway blockage, so that the secretions in the mouth can not be swallowed normally, with the pharynx peristalsis out of the mouth to form foam, sleep will appear spitting white foam The performance of snoring. If the airway is seriously blocked, it is recommended to take surgical removal treatment to keep the airway open; 3, respiratory inflammation: inflammation leads to congestion and edema of the nasal mucosa, abnormal hypertrophy of the tonsils, and obstruction of air exchange in the throat. Children can’t inhale through the nose when they sleep, and nasal secretions flow backwards, thus causing the symptoms of sleeping and snoring with white foam to appear. Need to be under the guidance of a doctor, according to the pathogen application of the appropriate sensitive antibiotic treatment; 4, indigestion: accumulation of food, gastrointestinal discomfort, poor sleep quality can cause snoring and mixed with saliva spitting white foam when sleeping. It is recommended to plan the diet rationally and not to use meals before bedtime; 5, obesity: when children are too obese, there is more fat in the neck and the uvula in the throat is thicker, and the respiratory system of the oropharynx is easily blocked at night when sleeping, and snoring occurs, which can be accompanied by the phenomenon of spitting white foam. Need to go to the hospital nutrition department, under the guidance of doctors for weight reduction treatment. Note parents should closely observe the child’s sleep status, if there is a sudden pause in snoring, it means the situation is more serious, it is recommended to seek medical attention as soon as possible.
