Little Junjun, a 3-year-old, 9-month-old boy, flew with his parents from Shenyang to Hangzhou for a trip in the spring. Little Junjun was so excited to go away for the first time that he pestered his mom and dad to play at the West Lake for half a day once he arrived in Hangzhou. It was not until it was completely dark that little Jun Jun took his mother’s hand and went to the hotel. However, less than half an hour after arriving at the room, little Jun suddenly developed breathing difficulties, coughing, purple lips and unfavorable spitting symptoms, which scared the parents and the mother bawled. Luckily, the waiter was calm and rushed to take the parents to a tertiary hospital across the road. After a brief examination of the patient, the hospital’s doctors determined that Xiao Junjun was suffering from “acute laryngeal obstruction (degree III) and acute laryngeal-tracheal-bronchitis” and immediately organized resuscitation. After 20 minutes of active treatment including nebulized inhalation and intravenous medication, the child’s condition stabilized. At this point, the doctor told little Junjun’s parents that it was lucky they got to the hospital in time, if they had been five minutes later, the child might have died. Acute laryngitis is an acute inflammation of the larynx that occurs in winter and spring, mostly in children between the ages of 6 months and 4 years. It is mostly associated with infection (bacterial or viral) and often follows an upper respiratory infection (cold). Due to the narrow laryngeal cavity, soft cartilaginous scaffold, and flabby submucosal tissue in pediatric patients, inflammation tends to engorge and swell, which can cause varying degrees of laryngeal obstruction. The clinical symptoms of mild acute laryngitis may be similar to those of the common cold, except that the cough may be bark-like (with a “hollow” cough sound) and may be accompanied by hoarseness. In severe cases of acute laryngitis with severe laryngeal obstruction, parents may observe difficulty breathing during inhalation, pale or purple face, panic, eyes wide open, irritability, and profuse sweating. Parents who encounter a child with laryngitis must seek prompt medical attention to prevent the adverse consequences of laryngeal obstruction that can lead to death by asphyxiation. It is important to keep the airway open during transport to the hospital and to comfort the child to keep him/her quiet to prevent crying from increasing the oxygen consumption of the body and aggravating the condition. Children with previous episodes of laryngitis have a tendency to have recurrent episodes, so parents should take precautions. If parents have a nebulizer at home, they can give emergency nebulized inhalation hormone treatment before visiting the doctor. Those who cannot be relieved may require intravenous hormones or even medical measures such as tracheotomy and ventilator-assisted breathing to save their lives, all of which require prompt medical attention to obtain.
