[Diagnostic value of procalcitonin in ventilator associated pneumonia].

Objective: To explore the diagnostic value of procalcitonin (PCT) quantification in ventilator associated pneumonia (VAP).

Methods: Sixty-one patients on ventilators were divided into VAP group and non-VAP group depending on whether the patients developed VAP in 7 days or not. The PCT levels were determined with the method of semi-solid phase immunoassay before and 7 days after instillation of mechanical ventilation in these patients.
