Abstract:
A 59-year-old man developed bilateral keratitis several weeks after the initiation of mechanical ventilation because of respiratory failure and sepsis following abdominal surgery. Colonisation of the upper airways by P. aeruginosa had been established before. Invasion through corneal epithelial defects based on dehydration keratitis was the presumed route of infection. Despite aggressive treatment, including antibiotics, the infection was rapidly progressive in both eyes. The patient died of deterioration of his general condition. In order to prevent such eye infections in a patient on mechanical ventilation, there is a need of good eye care, prevention of corneal lesions and alertness, especially when the patient is colonised by virulent micro-organisms like P. aeruginosa.
Insights
Mechanical ventilation can lead to severe eye infections like keratitis, especially with Pseudomonas aeruginosa colonization. Prompt eye care and lesion prevention are crucial for at-risk patients.
Area of Science:
- Ophthalmology
- Critical Care Medicine
- Infectious Diseases
Background:
- Mechanical ventilation is a life-support measure for respiratory failure.
- Sepsis and abdominal surgery are significant risk factors for complications.
- Pseudomonas aeruginosa is a common opportunistic pathogen in hospital settings.
Observation:
- A 59-year-old male on mechanical ventilation developed bilateral keratitis.
- Corneal infection was presumed to arise from epithelial defects and prior P. aeruginosa colonization.
- The patient had undergone abdominal surgery and suffered from sepsis.
Findings:
- Despite aggressive antibiotic treatment, the keratitis rapidly progressed.
- The patient's general condition deteriorated, leading to death.
- Dehydration keratitis may have facilitated pathogen invasion.
Implications:
- Mechanical ventilation requires vigilant ocular care protocols.
- Preventing corneal lesions is essential in critically ill patients.
- Early detection and management of P. aeruginosa colonization can mitigate risks.
