Summary
Nosocomial sinusitis, an infection acquired in hospitals, frequently occurs in severely injured patients with nasopharyngeal tubes. Prompt diagnosis and treatment are crucial for patient recovery and preventing complications.
Area of Science:
- Infectious Diseases
- Critical Care Medicine
- Otolaryngology
Background:
- Nosocomial infections pose a significant threat in intensive care settings.
- Nasopharyngeal instrumentation is common in severely traumatized patients.
- Sinusitis can be a challenging diagnosis in critically ill patients.
Purpose of the Study:
- To identify the incidence and characteristics of nosocomial sinusitis in severely traumatized patients.
- To determine common pathogens and predisposing factors for this infection.
- To evaluate treatment outcomes and emphasize the importance of early diagnosis.
Main Methods:
- A 24-month retrospective review of 32 severely traumatized patients with nasopharyngeal instrumentation.
- Diagnosis based on radiographic evidence of sinusitis and purulent sinus aspirates or nasal discharge.
- Microbiological analysis of sinus aspirates to identify causative pathogens.
Main Results:
- 34 cases of nosocomial sinusitis were identified, representing 5% of all nosocomial infections.
- Predisposing factors included nasotracheal/nasogastric tubes, nasal packing, corticosteroids, and fractures.
- Gram-negative bacilli were the most common pathogens; 14 infections were polymicrobic.
- Clinical resolution occurred in 20 patients after treatment and tube removal; 7 had persistent radiological abnormalities.
Conclusions:
- Nasopharyngeal instrumentation is a significant risk factor for nosocomial sinusitis in trauma patients.
- Fever and leukocytosis in patients with indwelling nasal tubes warrant investigation for sinusitis.
- Early diagnosis and management are essential to improve outcomes and reduce morbidity.
