Abstract :

BACKGROUND: Ventilator Associated Pneumonia (VAP) is a subset of pneumonia and the term refers to nosocomial pneumonia in a patient on mechanical ventilator support by endotracheal tube or tracheostomy for greater than or equal to 48 hours. VAP continues to be a major threat to patients admitted in intensive care units and receiving mechanical ventilation.

AIM: To study the incidence and etiology of VAP. To analyze the underlying risk factors for VAP. To study the percentage of early and late onset pneumonia in these patients. To study the morbidity and mortality attributed by VAP.

MATERIALS AND METHODS: The study comprised of 50 patients who were admitted in IMCU and had underwent mechanical ventilation for 48 hours and clinical criteria was applied to diagnose VAP.

RESULTS AND CONCLUSION: The incidence of VAP increases with the duration of mechanical ventilation. The major precipitating factor for developing VAP was aspiration. Diabetes is one of the major risk factor to develop VAP. There was a High incidence of MDR organisms in patients with VAP unlike in community acquired pneumonia.
