Ventilators in ICU: A boon or burden

Area of Science:

• Critical Care Medicine
• Infectious Diseases
• Neurology

Background:

• Ventilator-associated pneumonia (VAP) poses a significant challenge in intensive care units (ICUs), particularly in neurological settings.
• Limited data exists on VAP in neurology and neurosurgery ICUs (NNICUs) within developing countries.

Purpose of the Study:

• To determine the incidence, risk factors, microbiological profile, and antibiotic resistance of VAP in an Indian NNICU.
• To provide insights for developing targeted preventive strategies.

Main Methods:

• Prospective study involving 100 patients admitted to a tertiary care NNICU.
• Collection of endotracheal aspirate and blood samples for analysis.
• Diagnostic procedures included complete blood count, microscopy, culture and sensitivity testing, and chest X-ray.

Main Results:

• The incidence of VAP was 24%.
• Acinetobacter baumannii was the most frequent pathogen (24.3%), with all isolates sensitive to meropenem.
• Duration of mechanical ventilation (P < 0.0001) and comorbid illnesses (P = 0.005) were significant risk factors, with ventilation duration being the sole independent predictor.

Conclusions:

• Prolonged mechanical ventilation is a key independent risk factor for VAP in NNICU patients.
• Understanding the microbiological landscape and resistance patterns is crucial for effective VAP management and prevention in this vulnerable population.
