Euvolemia—A critical target in the management of acute kidney injury

Abstract

It has been clearly established that critically ill patients with sepsis require prompt fluid resuscitation. The optimal amount of fluid and when to taper this resuscitation is less clear. There is a growing evidence that fluid overload leads to acute kidney injury, and increased morbidity and mortality. A clinician's best intentions in resuscitating a patient can lead to too much of a good thing. Currently, there are several bedside tools to aid in determining a patient's response to a fluid challenge as well as in the assessment of the current volume status. Guidelines are not available on the exact rate of fluid overload removal and what medicinal or mechanical modality is most favorable. We discuss our experience and an examination of the literature on the problems with fluid overload, and how a patient may benefit from forced fluid removal.
