The idea that snoring during sleep may be a serious health hazard has gradually been recognized by the general public. However, snoring in children is often ignored by parents because the symptoms are relatively insidious. In fact, it is possible that children snoring is also a serious health hazard – obstructive sleep apnea hypoventilation syndrome (OSAHS), and since children are at an important stage of rapid physical and mental growth and development, the physical and mental health hazards of sleep snoring are more serious, and if not treated in time, it may bring lifelong If left untreated, it may bring lifelong regret. Some parents of children with snoring affect their intelligence and development. Some parents of children with snoring often hear teachers complaining that their children are inattentive in class, crossed ears, irritable and active, and have poor academic performance. In children, even a short sleep apnea or hypoventilation will lead to a decrease in blood oxygen saturation, and factors such as hypoxia and hypercapnia will affect the secretion of growth hormone or reduce the responsiveness of tissues and organs to growth hormone, resulting in malnutrition, short stature, delayed intellectual development, inattention, decreased academic performance, and even serious In serious cases, the growth of the child may be stalled. Parents should pay attention to the sleep condition of children at night, once they find snoring, open-mouth breathing, restless sleep, excessive activity, excessive sweating and urine loss, they should consult the doctor in time to avoid missing the time of treatment. Children’s snoring is likely to cause facial deformity. Children’s craniofacial bone development is 60% complete at the age of 4 and 90% complete by the age of 11. Childhood is an important stage in the formation of breathing pattern. The transoral breathing pattern caused by nasal congestion and open-mouth breathing during sleep adversely affects the facial growth and dental occlusion, and about 15% of children with OSAHS develop adenoid facial features, which are characterized by narrow upper jaw, high arch of hard palate, uneven teeth, protruding upper incisors and indifferent expression. This not only affects the child’s facial appearance, but also may affect the child’s future physical and mental development, thus creating a shadow on the child’s ability to adapt to society, such as choosing a job, choosing a spouse and interpersonal communication. Children with OSAHS are prone to hypertension, heart disease, asthma and other diseases. The recurrent apnea and hypoventilation caused by hypoxia and hypercapnia in children’s sleep lead to constriction of small pulmonary arteries and increased resistance of pulmonary circulation, thus increasing the right heart load. Researchers at the University of Hong Kong found that children who snore are prone to high blood pressure and reduced vascular elasticity, and are also prone to cardiovascular disease when they grow up. A recent Australian study shows that the proportion of children who snore frequently during sleep with nighttime cough is significantly higher than that of children who do not snore, and nighttime cough is a major danger signal for asthma; the increase of negative pressure in the upper airway obstruction chest cavity leads to gastroesophageal reflux during sleep, and secretions are inhaled into the lungs by mistake to stimulate the respiratory mucosa, which can cause wheezing, coughing and recurrent upper respiratory tract infections, thus making the respiratory mucosa more sensitive It is easy to cause asthma. If you pay more attention to your child’s sleep, you may be able to avoid a lifelong affliction. Of course, not all snoring is obstructive sleep apnea hypoventilation syndrome. Foreign statistics show that the incidence of obstructive sleep apnea syndrome in children is 2% to 3%. In order to clarify the severity of apnea and hypoxia and to guide further treatment, a physical examination in the otolaryngology department of the hospital and a lateral nasopharyngeal film, nasopharyngeal endoscopy and PSG examination should be performed. The “gold standard”. The child is usually required to undergo 7 hours of sleep monitoring in the monitoring room. By connecting electrodes to different parts of the body, more than 10 indicators such as brain waves, eye waves, heart rate, oral and nasal airflow, electromyographic activity, snoring, chest and abdominal breathing, and oxygen saturation are recorded simultaneously, and finally the data are analyzed by computer to reach a conclusion. How should a diagnosis of OSAHS be treated? Unlike adults who mostly need to be treated with ventilator, children’s snoring is usually caused by tonsillar hypertrophy and adenoid hypertrophy, etc. Most of them can be corrected by surgery with remarkable effect. A small percentage of children with adenoidectomy and tonsillectomy still have more severe sleep apnea, which requires further application of non-invasive ventilation therapy, and as children grow and develop, they do not necessarily need long-term nCPAP therapy, which is also very different from adults. In addition to all the hazards of adult OSAHS, OSAHS in children will directly affect the physical and intellectual development of the child, and the treatment effect is usually quite good and should be treated early to avoid lifelong regrets.
