Bacterial tracheitis, also known as "bacterial croup," "acute laryngotracheobronchitis," or "membranous croup," is a potentially lethal infection of. Bacterial tracheitis is due to a secondary bacterial infection of the trachea, resulting in the formation of mucopurulent exudates that may acutely obstruct the Abstract · PATHOPHYSIOLOGY · CLINICAL FEATURES · TREATMENT. Bacterial tracheitis is bacterial infection of the trachea. Bacterial tracheitis is uncommon and can affect children of any age. Staphylococcus aureus and group A beta-hemolytic streptococci are involved most frequently.

The author suggested that tracheal aspirates obtained in patients with suspected bacterial tracheitis should be analyzed for both aerobic and anaerobic bacteria As previously discussed, viral co-infection is common, particularly with parainfluenza type 1 the most frequent cause of viral croup and influenza virus 912 Although it may affect adults, it is primarily a disease of children between the ages of six months and 14 years, with a peak incidence around three to eight years of age 5891217 — The reported male to female ratio is quite variable, between bacterial tracheitis Most published case series, however, clearly show males bacterial tracheitis more commonly affected than females, with only a single large series showing no sex differences 58 bacterial tracheitis, 91217 — There are no specific risk groups identified to date.
Bacterial tracheitis is an uncommon cause of hospital admissions, with an overall reported incidence of 0.
bacterial tracheitis These data are based on discharge diagnoses entered into a global computerized database and do not explicitly include bronchoscopy-proven cases. This may account for the discrepancy with published data.

Alternatively, it is also possible that the illness is now more frequently recognized by physicians dealing with paediatric patients. It is our impression that the disease incidence fluctuates with time, level of clinical suspicion and diagnostic thresholds.
In this condition there bacterial tracheitis be inflammation of the linings of the trachea. A condition called tracheo-bronchitis can be caused, when the mucous membrane of the trachea bacterial tracheitis bronchi swell.
A collapsed trachea is formed as a result of defect in the cartilage, that makes the cartilage unable to support the trachea and results in dry hacking cough.
Bacterial Tracheitis: Causes, Symptoms, and Diagnosis
Evaluation The diagnosis of bacterial tracheitis is clinical with a thorough history and physical examination. Children may appear febrile, toxic-appearing, and in respiratory distress.
Trial bacterial tracheitis nebulized bacterial tracheitis and glucocorticoids will fail to show improvement in the patient's clinical course.
Laboratory investigation with white blood cell count is variable and nonspecific.

Leukocytosis, as well as mild leukopenia, are commonly seen. Blood cultures are rarely positive, however, should be obtained with suspicion for sepsis or in the immunocompromised. Radiographic images of the lateral or anteroposterior neck show tracheal narrowing, typical of that seen bacterial tracheitis croup.
Bacterial tracheitis commonly, irregularity or haziness of the tracheal mucosal wall can also be seen on lateral neck radiographs. This has been bacterial tracheitis to as the "candle dripping" sign.
The epiglottis should appear normal. The tracheal air column can sometimes be visualized with atypical clouding.

Airway stabilization should be a priority before obtaining imaging in patients with severe respiratory compromise. Presence of concomitant pneumonia increases the severity of disease and the probability of endotracheal intubation.
Definitive diagnosis is made by direct visualization, although is not necessary with strong clinical suspicion. Bronchoscopy allows visualization of the infected airway bacterial tracheitis will demonstrate a normal or bacterial tracheitis erythematous epiglottis and an erythematous, edematous trachea with thick mucopurulent exudates.
Bronchoscopy is performed with either a rigid or bacterial tracheitis endoscope, with the former suggested for suctioning the exudations to provide transient relief of airway obstruction as well as obtain specimens for culture.
