Symptoms of laryngitis

Laryngitis is more common in children. Acute laryngitis in children mainly occurs in infants between six months and three years old. It is mainly caused by some anatomical characteristics and developmental causes of weak coughing function and difficulty in expelling sputum. At the same time, it is mainly common in young children. Young children mainly have varying degrees of fever that causes coughing and swelling of the throat. It is also a common treatment method in daily life.

For general treatment and extreme treatment for adults, it is also appropriate to eat more fruits and vegetables to enhance the maintenance of the throat. At the same time, you must have a regular diet and regular living in your daily life. Keep your oral hygiene and eat more nutritious foods. Try to reduce going out during the cold to avoid infection.

Clinical manifestations

Acute laryngitis in children is common in infants and young children aged 6 months to 3 years. Due to the anatomical characteristics of the larynx in children, the laryngeal cavity is narrow, the laryngeal cartilage is soft, the lingual surface of the epiglottic cartilage, arytenoid cartilage, arytenoid epiglottic folds, ventricular zone and subglottic submucosal tissue are loose, and the mucosal lymphatic vessels are rich. After inflammation, it is easy to swell and cause laryngeal obstruction. Children do not have a strong cough function, and it is not easy to expel laryngeal and lower respiratory tract secretions, which makes breathing difficulties worse. Therefore, the condition of acute laryngitis in children is often more serious than that of adults. If not diagnosed and treated in time, it may be life-threatening.

diagnosis

Medical history: It is more common in young children, with acute onset.

Symptoms: There may be varying degrees of fever, hoarseness, barking cough and inspiratory stridor. The symptoms are milder during the day and worsen at night due to relaxation of the throat muscles and blockage of secretions after falling asleep.

Signs:

1. It is more common in young children and has an acute onset.

2. There may be varying degrees of fever, hoarseness, barking cough and inspiratory stridor.

3. The throat is congested, the false vocal cords are swollen, and the subglottic mucosa is swollen in a fusiform shape.

4. The symptoms are milder during the day, but worsen at night due to relaxation of throat muscles and blockage of secretions after falling asleep.

5. Laryngeal obstruction is divided into the following 4 degrees:

Grade I: The patient is like a normal person at rest. Inspiratory stridor and dyspnea only occur after activity. Lung breath sounds are clear and the heart rate does not change.

Grade II: Laryngeal stridor and inspiratory dyspnea occur even at rest. Laryngeal conduction sounds or tubular breath sounds may be heard upon auscultation of the lungs, and the heart rate is relatively fast.

Grade III: In addition to the symptoms of grade II laryngeal obstruction, the patient becomes irritable, has cyanosis of the lips, fear and sweating due to lack of oxygen. Auscultation of the lungs reveals significantly reduced breath sounds, dull heart sounds and an accelerated heart rate.

Grade IV: After struggling with breathing difficulties, the patient gradually becomes exhausted and drowsy. Due to the inability to breathe, the patient is temporarily quiet and the three-depression sign is not obvious. However, the face is pale and gray, and the breath sounds on lung auscultation almost disappear. Only tracheal conduction sounds are heard, the heart sounds are dull, and the heart rate is either fast or slow and irregular.

Physical examination: congestion in the throat, swelling of the false vocal cords, fusiform swelling of the subglottic mucosa, laryngeal striae and inspiratory dyspnea may sometimes occur depending on the severity of the lesion, and laryngeal conduction sounds or tubular breath sounds may be heard by auscultation of the lungs.

The above are the symptoms of laryngitis, some anatomical characteristics and the development of some diseases that cause weak coughing function and difficulty in expelling sputum, pay attention to climate changes, daily outdoor exercise, laryngeal stridor and inspiratory dyspnea, laryngeal conduction sounds or tubular breath sounds can be heard by auscultation of the lungs, and prevent complications from other types of diseases, which are also critical in daily life. .
