Anterior tracheal space infection
Introduction
Introduction to pretracheal infection The anterior tracheal space is located between the anterior trachea and the trachea, down to the upper mediastinum. Clinical infections are rare, mainly secondary to laryngeal and esophageal injuries and thyroid inflammation. Initially due to mild edema of the throat and hoarseness, when the degree is aggravated, there may be difficulty in swallowing and difficulty in breathing. The use of sufficient effective antibiotics to assist local physical therapy may contribute to inflammation control. Abscess formation should be cut and drained. basic knowledge The proportion of illness: 0.005% Susceptible people: no specific population Mode of infection: non-infectious Complications: septic shock pneumonia
Cause
Causes of pretracheal space infection
Trauma (35%):
Including foreign bodies, fish bones and instrument damage during endoscopy, the anterior wall of the esophageal or cervical esophagus is worn.
Thyroid inflammation (30%):
The direct spread of thyroid inflammation is rare. Patients with acute thyroiditis may develop thyroid abscess and pre-tracheal abscess. However, after the widespread use of antibiotics, it is rare that thyroid inflammation is caused.
Prevention
Prevention of tracheal anterior space infection
Pay attention to eating fresh fruits and vegetables rich in vitamins, and drink warm water. It is also necessary to properly carry out outdoor activities, exercise, and aerobic exercise to enhance the body's ability to resist pathogenic microorganisms. Active prevention of colds, etc.
Complication
Complications of anterior tracheal infection Complications , septic shock, pneumonia
There are mainly airway obstruction, asphyxia, lung and mediastinal infection, etc. The infection of the anterior tracheal space is easy to spread to the posterior pharyngeal space.
Symptom
Symptoms of anterior tracheal infection Common symptoms Difficulty of appetite, loss of appetite, fatigue, cough, hoarseness, pharyngeal paraesthesia, abscess, laryngeal edema, congestion
Symptoms caused by inflammation and edema of the throat and throat vary depending on the location and extent. Initially, the patient has hoarseness due to mild laryngeal edema, vocalization or throat sound (this is the earliest symptom) As the extent of inflammation and edema expands and the degree increases, different levels of dysphagia and dyspnea may occur, and severe cases may occur asphyxia.
Neck examination can find different degrees of swelling, tenderness or inflammatory mass in the anterior and posterior lingual area of the upper side of the affected neck. If it is caused by instrument damage, it can often be found that there is a sign of gas in front of the neck, such as depression. Edema should be alert to the formation of abscesses, but there is little sense of fluctuation.
Patients may have systemic symptoms such as fever, loss of appetite, and fatigue.
Examine
Examination of pretracheal infection
Peripheral blood shows an increase in white blood cell count.
Laryngoscopy, visible laryngeal pharynx, throat congestion, edema, can involve epiglottis, sacral cartilage and other parts, and finally involving the ventricular zone, throat and vocal cords.
Diagnosis
Diagnosis and identification of pretracheal infection
1. History has a history of laryngeal trauma or a history of thyroiditis.
2. Clinical manifestations of pharyngeal congestion, swelling, pain and tenderness, hoarseness, and symptoms of systemic poisoning.
3. Laryngoscopy consistent with the performance of the tracheal anterior space infection.
