Childhood asthma is a common high-risk disease. After the occurrence of asthma, the impact on personal health is relatively serious. It is necessary to know the basic symptoms of childhood asthma, find out the physical discomfort as soon as possible, and carry out relevant treatment and nursing as soon as possible, so as to better avoid the potential harm of asthma, Here is a detailed introduction to the basic characteristics of childhood asthma.
What are the characteristics of childhood asthma
First, the symptoms at the time of onset. The onset of the disease can be acute or slow. Children usually have symptoms of respiratory tract infection for one or two days before the onset of the disease, which is mainly similar to general bronchitis, but older children have an acute onset, and most of them break out at night, which is closely related to the climate and night changes, It also has an essential relationship with the possible accumulation of more dust and mites indoors and less adrenaline secretion at night. A few hours or a day after the attack, the patient’s condition will be a little relieved.
Second, the symptoms at the time of attack. During the attack, children generally have difficulty breathing and irritability, and often can’t lie flat. When sitting, they shrug their shoulders, and sometimes the wheezing sound can spread to the outside. Pale complexion, cyanosis of lips and nails, even cold sweat, uneasy face, showing a very serious situation. In this way, we should pay more attention and deal with it in time. At the beginning of the onset, there may be only cough, and then slowly aggravate to the symptoms of wheezing. With the relief of bronchospasm, the viscous white sputum is discharged, and the breathing is gradually calmed down.
When some patients cough, they will cause pain in the muscles of the upper abdomen, or accompanied by fever. The sign of the chest is three concave signs such as chest depression. During exhalation, due to the increase of intrathoracic pressure, there is reverse protrusion in the suprasternal recess and costal space, and the jugular vein is significantly dilated. In more serious patients, the two lungs can hardly hear sound absorption, and the right heart load increases due to pulmonary artery spasm, which may lead to hypoxia and cardiac failure.
Third, intermittent symptoms during attack. Such patients do not have any difficulties when breathing. They look like normal children, but they will feel discomfort in the chest. Because the factors leading to bronchial infection exist, they will immediately burst into asthma when they are infected with external stressors.
The sputum of children with bronchial asthma is generally colorless, viscous and transparent. Sometimes there are some bubbles, but the occurrence of infection will lead to the yellowing of the sputum. It is found that the sputum contains a large number of eosinophils when examined by hospital instruments. Most children’s sputum is not easy to cough up, and the amount is relatively small. When the characteristics are relieved, the sputum will also be significantly improved.
Fourth, chronic recurrent symptoms. Asthma itself is a chronic disease. Patients are suffering from the disease for a long time, but they can be controlled and relieved by drugs, but the remission period is very short, mostly due to adverse control of acute attack or repeated infection.
The above introduces the characteristics of children’s asthma. I hope parents need to master more parenting knowledge at ordinary times and actively do a good job in the prevention and treatment of children’s asthma, so as to avoid the potential harm of children’s asthma.
