Parents should pay attention to the symptoms of asthma in children

If a child develops asthma, parents must pay attention to it and avoid asthma attacks. Repeated asthma attacks are very harmful to the child's health. Parents must know the signs and early manifestations of asthma attacks in children and avoid the presence of some irritating factors.

1. Precursors and early manifestations of asthma attacks. First, let us understand the precursors of asthma attacks in children. When children with asthma are stimulated by allergens, cold air or other triggers, they often first show symptoms of upper respiratory tract allergies, such as itchy eyes, itchy nose, sneezing, runny nose, etc., and may also show symptoms such as rubbing the nose and eyes, and further manifest as itchy upper palate, itchy throat, dry cough and choking cough. These symptoms of childhood asthma can often last for hours or days before an asthma attack.

2. Remission period. Asthma does not occur all the time, but there is a remission period. During this stage, children with asthma may not have any symptoms and signs, or may only show symptoms of allergic rhinitis. A small number of children with asthma may experience chest discomfort, with or without wheezing in the lungs. Those with long-term recurrent attacks may have symptoms such as emphysema, which are the symptoms of childhood asthma.

3. During a typical attack, asthma symptoms are very obvious. The wheezing symptoms of childhood asthma vary greatly depending on the severity of the asthma. Children may have a high-pitched wheeze that can be heard without a stethoscope or at a distance. Symptoms of asthma in children include increased respiratory rate and difficulty breathing, and patients may breathe through their mouths with flaring nostrils. Many children may have cough, which is usually a dry cough at the beginning of the disease. When the attack subsides, white mucous sputum is coughed up. In severe attacks, symptoms include irritability, cyanosis, pale complexion, and cold sweats. Physical examination revealed three-recess sign, increased heart rate, and wheezing in both lungs. Further aggravation may lead to symptoms of heart failure such as distended neck veins, edema, small bubbling sounds in the middle and bottom of the lungs, and enlarged liver. Children with chronic pediatric asthma may have signs of emphysema, such as barrel-shaped chest and tympanic sound on chest percussion.
