Recently, a large number of children with cough and asthma have come to the pediatric clinic, and many parents have been anxiously surrounding the doctor, asking repeatedly whether their children have asthma. Will it be frequent in the future? Can the treatment “get rid of the root”? Some children with cough and wheeze are asthmatic and some are not. A foreign body in the airway or esophagus can also cause coughing and wheezing. Xiaohao had been coughing and wheezing for nearly 20 days and had been diagnosed with asthmatic bronchitis at several hospitals, but after treatment, he still had severe coughing and wheezing and could not sleep at night. Doctors immediately gave Xiaohao three-dimensional CT airway, found that there is a foreign body in the tracheal bulge, laryngoscopy to remove the foreign body, is a small thumb cap size peanut peel. Xiao Ming is a 13-month-old boy, previously 6 months old fever, coughing and wheezing, cured after a few days of treatment, this time again coughing and wheezing, parents thought “old disease recurrence”, came to the hospital a chest X-ray, found a metal foreign body in the esophagus, gastroscopy to remove the foreign body coughing and wheezing immediately disappeared, this foreign body is a dime coin, parents The parents wondered when the child ate it, but later the grandmother recalled that the day before the child’s coughing and wheezing, she had taken the money jar and shook it to play with it, and it was estimated that one fell out and the child ate it and got stuck in the narrow part of the esophagus. Children are small, curious, and incapable of judging dangerous things, so parents should watch carefully to prevent their children from accidentally taking drugs, coins, thermometers, etc. They should also not let their children cry, laugh, run, or make a scene while eating to prevent accidental inhalation of food into the airway, causing choking and coughing. Sinusitis can also cause coughing and wheezing. When coughing occurs, we always habitually think that something is wrong with the trachea or lungs. In fact, there are many different causes of coughing, and nasal diseases can also cause coughing. Diseases such as sinusitis and hyperplasia can cause coughing by dripping inflammatory secretions from the nasopharynx and stimulating the cough receptors in the throat, as well as aspiration of microscopic secretions and the nasal-bronchial reflex and inflammation of the upper airway. The onset of the cough is often induced or aggravated by a cold, and sometimes the patient has a hoarse voice, and even speech can induce a cough, etc. The cough mainly occurs at night and early in the morning, and may be accompanied by flu dripping from the throat, a foreign body sensation in the oropharynx, or a feeling of “paste sticking to the throat,” as well as frequent throat clearing, throat itching, or nasal itching, nasal congestion, runny nose, and sneezing. Gastroesophageal reflux can also cause coughing and wheezing. The distal mucosa of the esophagus has cough receptors, which can cause coughing through the vagal reflex when stimulated by gastric contents or acid reflux, or even accidental aspiration into the trachea; it is also thought to be related to protein hydrolases (pepsin and pancreatic protease), and is more common in obese children. In addition to coughing, it can cause asphyxia, bradycardia and back arching in infants and growth arrest or delay in older children, and feeding difficulties, mostly after eating. The symptoms of asthma in children vary widely depending on the severity of the asthma. The child may have a high-pitched wheezing sound and a “hissing” sound when exhaling, similar to the sound of a wind box being pulled. Infants and young children may exhibit open-mouth breathing and nasal flapping. Many children may have a cough, usually a dry cough at the beginning and white mucus-like sputum when the attack subsides. Severe attacks may be characterized by irritability, cyanosis, pallor, and cold sweats. Cough is a common symptom of respiratory disease and is usually associated with a respiratory infection when diagnosed. One type of cough that is different is cough variant asthma. Some patients with asthma start with frequent coughing without wheezing symptoms or feel chest tightness from time to time and take a long breath to relieve it. These patients are treated with antibiotics and cough suppressants, although the effect is not obvious. It takes quite a long time (months or even years or more) for croup to appear in the lungs with shortness of breath. Such patients are highly susceptible to misdiagnosis. A child’s cough after exercise may be exercising asthma Normal people can experience shortness of breath after sudden exercise or a certain amount of physical activity without croup, which can be relieved after a short rest, while some people experience an acute asthma attack with coughing, shortness of breath and croup at the time of exercise or after a few minutes of exercise, which is called exercising asthma and is a special type of bronchial asthma. Parents are reminded that coughing and wheezing is the most common disease symptom in children, but there are many diseases that cause coughing and wheezing, which need to be diagnosed and then treated in a targeted manner.
