Dry cough in children

Introduction Dry cough in children is the main manifestation of pediatric rhinitis. Most children with pediatric rhinitis are allergic. The symptoms are nasal congestion, cold air sneezing, runny nose, nose reflux, memory loss, and poor sense of smell. Many children can also be accompanied by itchy nose, itchy eyes and tears, which are manifested by repeated recurrent sputum (squeaky nose) and rubbing eyes, called allergic rhinoconjunctivitis. Many children with allergic rhinitis can develop a sudden paroxysmal cough (dry cough) or even asthma, called "allergic rhinitis asthma syndrome."

Cause

Intranasal inflammatory secretions from patients with rhinitis can flow into or into the lungs through the posterior nasal orifice and pharynx, known as postnasal drip syndrome. In particular, intranasal inflammatory secretions in the supine position sleep into the airway unconsciously, and it is very likely that allergic rhinitis develops into an important cause of asthma (especially nocturnal asthma). Changes in breathing patterns are also one of the factors that contribute to the close relationship between allergic rhinitis and asthma.

Medical history and physical examination: Detailed medical history, as far as possible to find the cause of dry cough including physical, chemical, biological reasons.

Pulmonary function: Children over the age of 5 should be routinely examined for pulmonary ventilation. If necessary, the bronchodilation test or bronchial provocation test can be performed according to the forced expiratory volume (FEV1) in one second.

Differential diagnosis

1, acute cough: refers to a course of less than 2 weeks, more common in the upper respiratory tract or lower respiratory tract infection and acute asthma attacks.

2, subacute cough: refers to the course of disease greater than 2 weeks and less than 4 weeks, in addition to respiratory infections can be seen in bacterial sinusitis and asthma.

3, chronic cough: cough symptoms for > 4 weeks called chronic cough.
