Objectives:
To determine the utility of microscopic examination and culture of endotracheal aspirate (ETA) in the early diagnosis of ventilator-associated pneumonia (VAP) in preterm neonates.
Methods:
We enrolled 80 consecutive neonates (both inborn and out-born) with gestational age of < 37 weeks admitted in Special Newborn Care Unit (SNCU) and requiring mechanical ventilation (MV) for ≥ 48 hours. The diagnosis of VAP was made using the criteria laid down by the Centers for Disease Control (CDC).
Results:
47 preterm neonates (58.5%) developed VAP; the overall incidence was 74.7/1000 ventilator-days. The mean (SD) time (hours) to ETA culture was less as compared to diagnosis based on CDC criteria [108.9 (8.00 hrs) vs 132.4 (53.24); P = 0.004] with sensitivity and specificity of 80.8% and 72.7%, respectively. Outborn delivery was the single most important risk factor for VAP. Multidrug resistant (MDR) Klebsiella pneumoniae (63.9%) was the most prevalent organism.
Conclusions:
We noticed a very high incidence of VAP among preterm neonates in SNCU. ETA culture can aid in early diagnosis.

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
