Children and urchins often fight, laugh, laugh and tease during eating time, and foreign bodies enter trachea and bronchus with inhalation, which is rare in adults. Coma patients sometimes mistakenly inhale vomit into the trachea. Some people mistakenly inhale their teeth into the trachea when extracting teeth.

First of all, judge

Melon seeds, peanuts, corn, beans and rice residue are often inhaled into the trachea. According to the age and the occurrence of choking cough, dyspnea, blue lips and foreign body blocking the glottis, there are dyspnea, three concave signs, cold sweat, irritability, aphonia and even suffocation. When a foreign body blocks one bronchus, it causes cough, wheezing and trouble, and shortness of breath is difficult. Those who stay in the trachea for a long time may have symptoms such as fever, expectoration with purulent blood, chest pain and emphysema.

Second, first aid.

Mainly take out foreign bodies quickly to prevent infection. The patient takes a semi-seated position, and the person who has difficulty breathing unbuttons his collar and is immediately sent to the hospital for emergency treatment.

Three. prevent

1. Children are included, and playing, laughing and crying are forbidden. Strengthen the management and education of children.

Children under three don't eat melon seeds, corn, peanuts, etc.

Tracheal foreign body

Symptoms and manifestations:

Patients should have a clear history of foreign bodies, and their symptoms can usually be divided into the following four stages:

1. Foreign body entry period: Patients are more likely to have sudden cough, severe paroxysmal cough and choking during eating, and may have symptoms such as asthma, hoarseness, cyanosis and dyspnea. If the foreign body is small and smooth, such as melon seeds, corn kernels, etc., the patient can hear the beating sound of the foreign body hitting the glottis when coughing, and can feel vibration when putting his hand in front of the larynx and trachea.

2. Quiet period: If the foreign body is small and non-irritating, or the foreign body enters the bronchus through the trachea, the symptoms of cough and breath holding are mild, or even disappear for a period of time, there will be a long or short asymptomatic period, which is easy to ignore the diagnosis.

3. Stimulation or inflammation stage: Plant-like tracheal foreign body, because it contains free acid, has obvious stimulating effect on tracheal mucosa. The bean-shaped tracheal foreign body expands after absorbing water, which is easy to cause airway obstruction. The longer the foreign body stays in the airway, the heavier the reaction. At first, it is an irritating cough, and then due to the increase of secretions in the trachea and the swelling of the tracheal mucosa, there will be symptoms of persistent cough, atelectasis or emphysema.

4. Complication stage: Foreign bodies can be embedded in one side of the bronchus, which will be wrapped by granulation or fibrous tissue for a long time, resulting in bronchial obstruction and secondary infection. Foreign bodies in the trachea exist for a long time, which has clinical manifestations similar to suppurative tracheitis: expectoration with blood, atelectasis or emphysema, causing dyspnea and hypoxia.

Family therapy:

The longer the foreign body stays in the trachea, the greater the harm. Therefore, foreign bodies in the trachea should be removed as soon as possible to avoid or reduce the chances of suffocation and other complications.

1. When the patient is in good condition, the foreign body can be taken out in time under direct laryngoscope or bronchoscope.

2. In order to prevent postoperative laryngeal edema, antibiotics or hormones can be given. Penicillin 800,000 units, twice a day, intramuscular injection, dexamethasone 5- 10 mg, 1 time a day.

3. If the patient has no obvious dyspnea, but has high fever, general weakness or severe dehydration due to serious complications such as bronchus or pneumonia, it is advisable to carry out anti-inflammatory and rehydration treatment first. Observe closely whether there is sudden dyspnea, and take out the foreign body after the body temperature drops and the general condition improves.

4. If the condition is serious and there is extreme dyspnea, tracheotomy, sedation and oxygen should be done first.
