Abstract
Background: Ventilator-associated pneumonia (VAP) is the most frequent life-threatening nosocomial infection in intensive care units. It develops in patients mechanically ventilated for at least 48 hours.
Objective: To evaluate if red cell distribution width has a prognostic value in ventilator associated pneumonia.
Patients and Methods: This retrospective study included adult patients (> 18 years) who were admitted to ICU and mechanically ventilated a total of 50 patients who were divided into 2 groups: group 1 (includes 25 patients): patients who were mechanically ventilated then developed ventilator associated pneumonia. group 2 (includes 25 controls): patients who were mechanically ventilated didn’t develop pneumonia during course of ventilation.
Results: In the current study RDW (red cell distribution width) is significantly higher in patients with pneumonia at the end of the study, also RDW is significantly higher in poor outcome in all study patients regardless developed pneumonia or not during MV.
Conclusion: RDW is used as an inexpensive index that is routinely reported as a part of the complete blood count, RDW is an important marker for both diagnostic and prognostic purposes in all cause mortality in ICU patients not specifically in mechanically ventilated patients. Larger studies and clinical trials are recommended to determine the clinical outcome of RDW prognostic value in VAP.
