Introduction

Introduction Stridalas respiration: occurs mostly in patients with inspiratory dyspnea. When the upper airway obstruction, air inhalation is difficult, a high-profile sound occurs when inhaling, called snoring-like breathing. Often accompanied by "three concave signs."

Cause

Cause

Laryngeal and tracheobronchial diphtheria is mostly caused by the spread of pharyngeal diphtheria to the larynx. More common in children aged 1 to 5 years old. The onset is slower with fever, the cough is "empty", the voice is hoarse or even aphasia. At the same time, due to the pseudomembrane, edema and paralysis of the throat, the respiratory tract obstruction may have a snoring sound when inhaling. In severe cases, the "three concave sign" may be seen when inhaling. The patient presents with convulsions and purpura laryngoscopy. And fake film. The pseudomembrane can sometimes extend to the trachea and bronchi, and in severe cases, there is also a pseudomembrane formation in the bronchioles.

Diagnosis

Differential diagnosis

Chest pain during inhalation: one of the clinical manifestations of chest wall pain. Features:

1. The place of pain is only concentrated, and the patient can clearly point it out.

2, the pain is not long, usually only one or two seconds each time, there is a chance to relapse.

3. When the patient takes a deep breath, coughs, sneezes or turns around, the chest is stinging and even painful.

4, the pain may be more intense than the chest pain caused by other diseases, but most of them improved within a few days to two, Samsung.

4. Any age will suffer.

Nasal obstruction during inhalation: The clinical manifestations of nasal valve stenosis are mainly nasal obstruction during inhalation, both unilateral and bilateral. The clinical manifestations were mainly nasal obstruction during inhalation. No abnormalities such as turbinate hypertrophy or polyps were found in the anterior nasal endoscopy. Lift the tip of the patient's nose and the nasal obstruction disappears immediately. If the thumb and forefinger are pushed to the sides of the nose, the nasal obstruction is immediately released, and the Cottle sign is positive.

Intubation occurs in the chest: severe closed chest injury leads to multiple rib fractures, so that the local chest wall loses the rib support and softens, and abnormal breathing, that is, in the softened area, the chest wall is invaded when inhaling, exhalation For the chest.
