Fatal, Fulminant Herpetic Tracheobronchitis following Cardiac Surgery

Area of Science:

• Infectious Diseases
• Virology
• Critical Care Medicine

Background:

• Nosocomial infections pose a significant risk following surgical procedures.
• Ventilator-associated respiratory infections, such as tracheobronchitis and pneumonia, are common complications in mechanically ventilated patients.
• Bacterial pathogens are the most frequently identified causes of these infections.

Observation:

• A fatal case of fulminant herpetic tracheobronchitis is presented in a 33-month-old patient.
• The patient developed this severe respiratory complication after undergoing cardiac surgery.
• The tracheobronchitis was caused by a herpes simplex virus infection.

Findings:

• Viral etiologies, particularly herpes simplex virus, are often underestimated in post-operative respiratory infections.
• Herpetic tracheobronchitis can manifest as a severe, life-threatening condition in immunocompromised or post-surgical patients.
• Early consideration of viral causes is crucial for appropriate diagnosis and management.

Implications:

• Clinicians should consider herpetic viral infections in the differential diagnosis of severe post-operative respiratory complications.
• This case underscores the importance of recognizing less common etiologies in ventilator-associated respiratory infections.
• Prompt identification and treatment of viral tracheobronchitis may improve patient outcomes and reduce mortality.
