Trirecesses due to inspiratory dyspnea

Analysis: Inspiratory dyspnea shows symptoms such as supraclavicular fossa, upper sternal part and intercostal space inspiration during inhalation, so it is called "three retractions". It is usually due to stenosis or obstruction of the upper airway.

Specifically, it can be seen in laryngeal edema or upper airway foreign body obstruction, and bronchial asthma may also occur in acute attacks, so for inspiratory dyspnea, the main thing is to relieve upper airway obstruction, glucocorticoids or endotracheal intubation, etc., to solve the above dyspnea. Analysis: According to the situation you described, female, 21 years old, the three-receptive sign refers to the obvious depression of the suprasternal fossa, supraclavicular fossa, and intercostal space during inspiration, which is due to inspiratory dyspnea caused by partial obstruction of the upper airway.

Bronchial asthma is another common cause of episodic acute airway obstruction, which can also present with retractions due to tracheal spasm as opposed to airway obstruction. Disease analysis: the three retractions are generally seen in inspiratory dyspnea, which is mostly related to airway blockage, and the asthma is expiratory dyspnea, and the three retractions are relatively rare, but when the condition is severe, it can also appear because of airway narrowing, and the three retractions refer to the supraclavicular fossa, the suprasternal fossa and the intercostal space have obvious depressions when inhaling, indicating difficulty in inhaling.

1) Inspiratory dyspnea:

Presentations: Effortless inhalation, inspiratory time > expiratory time, with obvious retractions (suprasternal fossa, supraclavicular fossa, intercostal space, or supraabdominal angle depression).

Cause: Partial obstruction of the upper airway. Occurs in patients with laryngeal edema and a foreign body in the larynx.

2) Expiratory dyspnea:

Performance: Exhalation is laborious, exhalation time > inhalation time.

Cause: Partial obstruction of the lower airway. It is more common in patients with bronchial asthma and emphysema.

3) Mixed dyspnea:

Presentation: Laborious inhalation and exhalation.

Causes: More common in patients with lung infections.

The three retractions are generally seen in inspiratory dyspnea, which is mostly related to airway obstruction, and the asthma is expiratory dyspnea, and the three retractions are relatively rare, but when the condition is severe, it can also appear because of airway stenosis, and the three retractions refer to the supraclavicular fossa, suprasternal fossa and intercostal space when inhaling, there are obvious depressions, indicating difficulty in inhaling.

Answer]: eInhalation is difficult to inhale, characterized by difficulty in inhalation. In severe cases, the supprasternal fossa, supraclavicular fossa, and intercostal space may be significantly depressed during inspiration, often accompanied by a dry cough and high-pitched inspiratory wheezing.

It is more common in laryngeal edema and spasm, and is related to upper airway stenosis obstruction caused by tracheal foreign body, tracheal compression, or tumor.

Answer]: A severe inspiratory dyspnea can have "three retractions", which are mainly manifested as suprasternal fossa, supraclavicular fossa, and intercostal space depression. It is more common in patients with laryngeal edema, tracheal foreign body slippage, or upper airway obstruction caused by compression fibrillation.

Initial consideration is pulmonary dyspnea.

In patients with pulmonary tuberculosis, there is increased tremor on the affected side. Superior and inflavicular area. The scapular area smells a wet gong sound after coughing.

A tracheal foreign body presents as paroxysmal cough.

Signs of obstructive emphysema: Wet and dry gong sounds may be heard at the base of both lungs, which may decrease or disappear with cough. Barrel chest develops as the disease progresses.

Signs of bronchial asthma. Accompanied by wheezing.

Pneumonia. Respiratory symptoms. Chest pain. Cough with sputum. Cough up rust-colored phlegm.

Pulmonary dyspnea refers to a respiratory disorder that causes a patient to subjectively feel that there is not enough air. Breathing is laborious. Objectively respiratory rate. Rhythm and depth abnormalities.

Answer]: a, b

The triadow deficiency sign refers to the extreme increase of negative pressure in the thoracic cavity due to the movement of the respiratory muscles during inspiration, resulting in obvious depression of the suprasternal fossa, supraclavicular fossa, and intercostal space. Common in patients with partial obstruction of upper breathing.

There is inflammatory exudative secretions during a bronchial asthma attack, and obstructive atelectasis occurs when it completely blocks the lumen, at this time there are both expiratory and inspiratory dyspnea, and the body compensates for the pressure difference between the intrapulmonary pressure and atmospheric pressure, so that the intercostal space, the supraclavicular fossa and the suprasternal fossa are depressed.

This is mainly a process of allergization of the bronchial part of the lesion to the air of the outside world, which is a means of self-protection of the body.

Answer]: a, b, d

Three-recessed sign"The suprasternal fossa, the supraclavicular fossa on both sides, and the lower intercostal space are significantly depressed during inspiration, and may also be accompanied by dry cough and high-pitched inspiratory laryngeal sound. It is common in the narrowing and obstruction of the larynx, trachea, and large bronchi. Left heart failure is indicated when accompanied by cyanosis, crackles in both lungs, and increased heart rate.

Answer]: a, b, e

The three-recalculation sign refers to the supragernal fossa, supraclavicular fossa, and intercostal space, and is commonly seen in stool laughing gas dyspnea such as laryngeal chakra edema and laryngeal foreign body.
