The causes of a baby’s cough are many and varied. It may be caused by a dry throat due to a lack of water in the body, a cough caused by a foreign body inhaled while feeding, or a cough caused by a respiratory infection, allergies or other lesions in the respiratory tract. The treatment of coughs differs from one cause to another. A cough may be triggered when your baby’s throat is too dry due to dehydration, when he or she inhales a lot of air while breastfeeding, or when he or she inhales some dust, atmospheric particles or pollen by mistake, causing the mucous membrane of the respiratory tract to adhere to some foreign objects. For larger foreign bodies, which are likely to cause damage to the throat, it is recommended to seek medical attention and remove the blocked foreign body under medical supervision. Parents need to take good care of their babies, try not to go to dusty environments, drink more water, and pay attention to keeping warm during the change of seasons to avoid coughing as much as possible. Pathological phenomena 1. Respiratory tract infections: In the case of upper respiratory tract infections, the baby’s cough is often accompanied by coughing up sputum, and in view of the baby’s weak constitution, non-pharmaceutical methods such as keeping the air moist, patting the back to expectorate and using water vapor for nebulization can be used first. In case the methods do not work, treatment can be carried out with pediatric cold and flu pellets, anti-inflammatory and antiseptic antibiotics and antipyretic drugs such as ibuprofen and acetaminophen under the guidance of a doctor. In addition, for babies with pharyngitis, rhinitis and bronchitis, who often have coughing symptoms, antibiotics can be used for anti-inflammatory treatment, and catecholamines can also be used to help dilate the bronchi; 2. Allergic reactions: common ones such as cough variant asthma, a childhood respiratory disease with cough as the main symptom, are often treated orally with amiloride combined with montelukast, which can reduce the baby’s 3. Other respiratory tract pathologies: If the baby has respiratory tract malformations, bronchopulmonary cysts, mediastinal tumors, ciliary dyskinesia, etc., this may also trigger the appearance of cough symptoms in babies. In addition, some babies may also develop cough due to gastroesophageal reflux, which is usually seen in infants and young children. If the baby has a dysfunctional digestive tract, some of the refluxed material from the stomach may enter the airway and irritate the pharynx, causing a cough. This can be treated with H2 blockers, mucosal protectors, proton pump inhibitors, etc. to relieve the cough symptoms.
