congenital laryngeal stridor
Introduction
Introduction to congenital throat wheezing Because the child's laryngeal cartilage is not well developed, his (her) throat cartilage covers the glottis when inhaling, and it will sound like a chicken. This is called congenital throat wheezing. Congenital laryngeal wheezing is caused by the weakness of the throat tissue, the collapse of the tissue during inhalation, and the small throat cavity, which is also called throat cartilage softening. It often occurs shortly after birth. As the age is older, the laryngeal cartilage gradually develops and the throat is gradually disappearing. basic knowledge The proportion of illness: 0.005% Susceptible people: good for children Mode of infection: non-infectious Complications: funnel chest chicken breast
Cause
Causes of congenital laryngeal wheezing
Malnutrition (30%):
Due to malnutrition during pregnancy, the lack of calcium in the fetus causes the laryngeal cartilage to be weak, and the negative pressure increases during inhalation, causing the edges of both sides of the epiglottic cartilage to curl inwardly, or the epiglottic cartilage is too large and soft, and the ankles on both sides will be close to each other. The throat is narrowed into a flap tremor and a throat is heard.
Cartilage prolapse (30%):
Inspiratory sacral cartilage prolapse is another cause. The throat of this child is not caused by the weakness of the laryngeal cartilage. Instead, when the inhalation, the sacral cartilage rotates forward and downward, and the loose tissue on the sound The front part of the door protrudes, blocking the glottis and causing a throat.
Prevention
Congenital throat wheezing prevention
If the child has this disease, he should be sent to the hospital for treatment in time. In addition to timely control of infection, attention should also be paid to malnutrition and electrolyte correction. If the treatment is proper, the general child will naturally disappear after 2 years of throat wheezing. For children, it may be very important to get more sun, enhance the child's constitution and prevent colds.
Don't be afraid of this disease, because as the age increases, the throat space will gradually increase, and the laryngeal cartilage will develop well. Most children will be around 2 years old, and this sound will disappear. Carefully take care of children, avoid infection with bronchitis, laryngitis and pneumonia. Third, let the children get more sun, do more outdoor activities, and give children calcium tablets and vitamin D in time.
Complication
Congenital throat wheezing complications Complication funnel chest chicken chest
Congenital laryngo has no obvious effect on its growth and nutritional status, but children with severe clinical manifestations may have funnel chest or chicken breast due to difficulty in breathing and long-term hypoxia. Because of lung function, some children may A heart enlargement occurs.
Symptom
Congenital throat wheezing symptoms Common symptoms Difficulty breathing, throat, sore throat, itchy throat
According to the history of laryngeal sounds shortly after birth, no history or signs of respiratory foreign body or other diseases, the X-ray of the lateral side of the throat is normal, the crying is loud and the swallowing is good, and the diagnosis can usually be made without direct laryngoscopy.
In the direct laryngoscopy, the epiglottic cartilage is long and pointed, and the two are curled back and touch each other; or they may be oversized and soft, and the epiglottis will be close to each other on the sides and the sacral cartilage. When the glottis is blocked, the laryngeal sound disappears after the laryngoscope is picked up by the direct laryngoscope, and thus the diagnosis can be confirmed.
The baby is still breathing normally at birth. The throat is gradually occurring 1 to 2 months after birth. Most of them are persistent or intermittently aggravated. The throat is only in the inspiratory period and may be accompanied by inspiratory dyspnea. Usually, the throat is not obvious. It happens immediately after stimulation. Some are related to body position. When you are lying on your back, you are aggravated. When you are lying down or lying on your side, most of the children are still in good condition, and the crying is not hoarse.
Examine
Congenital throat wheezing
Shortly after birth, the baby has a history of throat wheezing, no history and signs of respiratory foreign body or other diseases, X-ray film on the lateral side of the throat is normal, cries are loud and swallowed well, and diagnosis is usually done without direct laryngoscopy. Direct laryngoscopy can be seen that the epiglottic cartilage is long and pointed, while the two sides are curled back and touching each other; or they will be oversized and soft, and the epiglottis will be close to each other on the sides and the blemishes; there will also be loose tissue on the cartilage. The glottis protrudes and blocks the glottis. After the epiglottis is picked up by the direct laryngoscope, the throat wheezing disappears, and the diagnosis can be confirmed.
Diagnosis
Diagnosis and diagnosis of congenital throat wheezing
According to the history of throat, shortly after birth, no history or signs of respiratory foreign body or other diseases. The X-slice on the lateral side of the larynx is normal, the crying is loud and the swallowing is good. Generally, a direct laryngoscopy is not needed to make a diagnosis.
Congenital larynx must be differentiated from other various congenital larynx and tracheal dysplasia such as throat, laryngeal fissure, tracheal cartilage softening, secondary laryngeal wheezing, etc., and should also be noted with various acquired laryngeal diseases such as inflammation. , foreign bodies, trauma and other identification.
