Study Notes

Overview of Bacterial Tracheitis

Bacterial tracheitis (BT) is a potentially lethal infection affecting the subglottic trachea, typically following a viral respiratory infection.
Common in children under six but can occur in any age group, especially in tracheostomy-dependent patients.
Treatment focuses on securing the airway due to the risk of obstruction from thick, mucopurulent secretions.

Etiology and Pathophysiology

Often occurs after a viral upper respiratory infection, with Influenza A being the most notable virus implicated.
Secondary bacterial infections are commonly caused by Staphylococcus aureus (including MRSA), Streptococcus pneumoniae, and Haemophilus influenzae.
Damage to the tracheal mucosa leads to opportunistic bacterial invasion, inflammation, edema, and excessive secretions, causing narrowing and potential obstruction of the airway.

Epidemiology

Estimated incidence varies by region, around 0.1 to 1 case per 100,000 children, with higher rates during fall and winter months concurrent with viral epidemics.
Peak incidence occurs in children aged three to eight years, with a male predominance.

Clinical Presentation

Typically begins with viral symptoms (cough, fever, sore throat) progressing to acute respiratory distress.
Common signs include stridor, high fever, hoarseness, and increased secretions; severe cases can lead to lethargy and cyanosis.
Tracheostomy-dependent patients may show different symptoms, including hemoptysis and elevated peak ventilatory pressures.

Diagnosis

Diagnosis is primarily clinical, based on history and physical examination findings.
Radiographic imaging may reveal subglottic or tracheal narrowing (steeple sign) and should be interpreted cautiously in severe respiratory distress cases.
Direct visualization via laryngoscopy or bronchoscopy is definitive, showing an edematous, exudative trachea.

Treatment and Management

Immediate airway assessment is crucial; intubation is common, with rates as high as 100% in certain studies.
Broad-spectrum antibiotics, including MRSA coverage, should be initiated promptly.
Antiviral therapy may be useful within 48 hours of influenza infection, while glucocorticoids generally do not influence outcomes.

Differential Diagnosis

Various conditions can mimic bacterial tracheitis, including epiglottitis, croup, peritonsillar abscess, and laryngeal malignancies.
Key distinguishing signs include drooling in epiglottitis and lack of drooling in bacterial tracheitis.

Prognosis and Complications

Early diagnosis and treatment lead to favorable outcomes; severe cases may require ICU admission and intubation.
Potential complications include ARDS, airway obstruction, septic shock, and tracheal stenosis.

Postoperative and Rehabilitation Care

Multidisciplinary management involving respiratory therapy, speech therapy, and case management is essential for patients with tracheostomies.
Ongoing care should include tracheostomy management, facilitating rehabilitation, and planning for decannulation.

Consultations

Prompt evaluations from otolaryngology and interdisciplinary teams are critical for optimal management and minimizing morbidity and mortality risks associated with bacterial tracheitis.### Deterrence and Patient Education
Bacterial tracheitis prevention is more effective in tracheostomy-dependent patients compared to those without tracheostomies.
Complete prevention of bacterial tracheitis in non-tracheostomy patients is not possible; hygiene practices like hand washing and mask-wearing are essential.
Vaccinations against Haemophilus Influenzae B, Streptococcus Pneumoniae, and Diphtheria help reduce tracheal infections.
Caregivers should seek medical evaluation for dyspnea or airway obstruction immediately.
Education for patients and caregivers is vital in managing tracheostomy care to prevent bacterial tracheitis.
Interprofessional teams should provide instruction on cleaning and maintaining ostomy sites and devices.
Inner cannulas should be cleaned with hydrogen peroxide, saline bullets, and suction several times a day to avoid mucous plugging.
Humidification is crucial to prevent crusting in tracheostomy care.
Local wound care strategies include barrier ointments, crust removal, and skin care to mitigate the risk of skin breakdown and tracheal contamination.

Pearls and Other Issues

Median hospitalization for pediatric patients without tracheostomy is typically 3 to 12 days, with most recovering without lasting effects.
Risks of subglottic stenosis from endotracheal intubation highlight the preference for uncuffed tubes by pediatric intensivists.
Estimated mortality from primary respiratory failure ranges from 2% to 3%.
Rare complications include septic shock (2-6%), cardiorespiratory arrest (2-3%), and ARDS (1-3%).
Vaccination is key for preventing viral and pneumococcal diseases, especially in immunocompromised children.
A study of over 4,000 pediatric tracheostomy patients noted a median hospital stay of 4 days and a 30-day revisit rate of 24.9%.
Tracheostomy-dependent children exhibit a higher all-cause revisit rate within 30 days.

Enhancing Healthcare Team Outcomes

Bacterial tracheitis requires management by an interprofessional team including various medical specialists and support staff.
Rapid airway compromise can lead to sudden death, making swift identification and intervention critical.
Pulmonary hygiene, through voluntary coughing and nebulizers for non-tracheostomy patients, and suctioning for tracheostomy patients, is vital.
Although surgical airways are seldom needed, preparedness is essential for non-tracheostomy patients.
Treatment includes antibiotics, close monitoring, and a readiness for intubation or tracheostomy if conservative treatments are ineffective.
Some patients may require prolonged mechanical ventilation or various forms of tracheostomy.
Immunocompromised patients often face more challenging outcomes due to their vulnerability.
