Pediatric acute laryngitis is a common disease in infancy and early childhood, most often occurring in late autumn, and is folklorically referred to as “lockjaw wind”. It is characterized by a rapid onset, fierce and sinister symptoms, and can be life-threatening if not rescued in time. The acute laryngitis in children is mostly caused by viruses, bacteria or allergies, mostly secondary to pharyngitis, rhinitis or cold, fever, cough, runny nose, hoarseness and other symptoms of upper respiratory tract infection 1 to 2 days before the onset of the disease, the mental state is still good, as the disease progresses, the inflammation from the pharynx continues to spread downward, so that the laryngeal cavity mucosa inflammatory swelling. In addition, the laryngeal cavity of children is small, and it is the way to breathe air. At this time, children often suddenly appear at night with a cough like breaking bamboo, breathing difficulties, and sometimes a “howl, howl” like barking. Significant inspiratory dyspnea can be seen in the child’s suprasternal fossa, intercostal fossa and subxiphoid fossa, showing the typical triple concave symptoms. Some children have sudden onset of croupy cough at night with hoarseness and trismus symptoms, called spasmodic laryngitis. Persistent airway obstruction may cause the child’s lips and mouth to become blue or comatose, requiring prompt resuscitation. If left untreated, the child often suffers from systemic failure due to impaired ventilation and can sometimes die suddenly from severe hypoxemia. Pediatric acute laryngitis is common in children under 5 years of age and is a serious life-threatening disease that should be taken seriously by parents and should be actively prevented during the onset of the season. To prevent the occurrence of pediatric acute laryngitis, parents should pay attention to keeping their children warm in the late fall and allow them to go outdoors more often to strengthen their systems and improve their resistance to disease. Weak children can take some nutritional supplements to strengthen their vitality and resistance. Children should also be taught to develop good hygiene habits by going to bed early and waking up early to avoid contact with influenza patients. Open windows and doors frequently to keep the air fresh. For children with symptoms of acute laryngitis, it is important to seek timely treatment and observe changes in their condition at all times to prevent any untoward incidents.
