Prevention of ventilator-associated pneumonia

Area of Science:

• Critical Care Medicine
• Infectious Diseases
• Pulmonology

Background:

• Invasive mechanical ventilation (IMV) is a life support measure for critically ill patients.
• Ventilator-associated pneumonia (VAP) is a significant complication, developing at least 48 hours post-intubation.
• VAP is the most frequent intensive-care-unit (ICU)-acquired infection, increasing mortality and healthcare costs.

Purpose of the Study:

• To highlight the risks associated with IMV and the development of VAP.
• To emphasize the imperative need for VAP preventive measures.
• To guide the implementation of evidence-based strategies for VAP control.

Main Methods:

• Review of existing literature and guidelines on VAP prevention.
• Focus on modifiable risk factors associated with IMV.
• Discussion of non-pharmacological and pharmacological evidence-based strategies.

Main Results:

• VAP significantly increases hospital mortality, duration of mechanical ventilation (MV), ICU stay, and overall hospitalization costs.
• Preventive measures are essential for controlling VAP incidence.
• Strategies aim to mitigate risks from endotracheal intubation and prevent lower airway pathogen microaspiration.

Conclusions:

• VAP poses a substantial threat to critically ill patients on IMV.
• Implementing guideline-recommended preventive strategies is crucial for reducing VAP rates.
• Effective VAP prevention improves patient prognosis and reduces economic burden.
