Objective
To verify the impact of mechanical ventilation use in patients admitted to the intensive care unit and the incidence of acute kidney injury.
Methods
A prospective, quantitative cohort study of 27 patients receiving mechanical ventilatory support while hospitalized in the intensive care unit of a public hospital.
Results
The majority (55.6%) of patients were classified according to the kidney injury stages listed in the Risk, Injury, Failure, Loss, End-Stage (RIFLE) classification. Of these patients, 45.8% received mechanical ventilation with between 5 and 10 cmH2O positive end-expiratory pressure and progressed to acute kidney injury. The Acute Physiology and Chronic Health Disease Classification System II (APACHE II) was significantly associated with renal dysfunction (p = 0.046).
Conclusion
The use of invasive mechanical ventilator support with positive end-expiratory pressure in critically ill patients in intensive care units can impair renal function.
