Achieving an appropriate level of volume management requires knowledge of the underlying pathophysiology, evaluation of volume status, selection of appropriate solution for volume repletion, and maintenance and modulation of the tissue perfusion. Prompt and adequate treatment with intravenous solutions can also prevent or limit subsequent AKI. In critically ill patients, adequate fluid resuscitation is essential to the restoration of cardiac output, systemic blood pressure and renal perfusion in patients with cardiogenic or septic shock. The role of fluid therapy in the development of fluid overload We will focus on the evaluation and management of fluid overload in the intensive care unit (ICU). In concert with these data, the control and optimization of fluid balance is a key element of critically ill patients management, since inadequate fluid removal is associated with peripheral edema and pulmonary edema, which can retard weaning from mechanical ventilation, or compromise wound healing. Restrictive fluid management strategies are beneficial during acute respiratory distress syndrome and following major surgery since they reduce the duration of mechanical ventilation and the rate of cardiopulmonary complications. Observational studies in pediatric patients who required continuous renal replacement therapy (CRRT) have shown an association between fluid overload and mortality. In critically ill patients, recent studies have highlighted the role of fluid overload on adverse outcomes. Increasing fluid overload should not merely be considered an expected consequence of fluid resuscitation or severe AKI, it should be seen as a probably mediator of adverse outcomes. Successful fluid overload treatment depends on precise assessment of individual volume status, understanding the principles of fluid management with ultrafiltration, and clear treatment goals.įluid overload is frequently found in critically ill patients with acute kidney injury (AKI). Diuretics are frequently used as an initial therapy however, due to their limited effectiveness the use of continuous renal replacement techniques are often required for fluid overload treatment. Therefore, the evaluation of volume status is crucial in the early management of critically ill patients. In critically ill patients, fluid overload is related to increased mortality and also lead to several complications like pulmonary edema, cardiac failure, delayed wound healing, tissue breakdown, and impaired bowel function. Fluid overload refractory to medical therapy requires the application of extracorporeal therapies. Diuretics, especially loop diuretics, remain a valid therapeutic alternative. There are several methods to evaluate fluid status however, most of the tests currently used are fairly inaccurate. Accurate volume status evaluation is essential for appropriate therapy since errors of volume evaluation can result in either in lack of essential treatment or unnecessary fluid administration, and both scenarios are associated with increased mortality. Fluid overload recognition and assessment requires an accurate documentation of intakes and outputs yet, there is a wide difference in how it is evaluated, reviewed and utilized. Numerous recent studies have established a correlation between fluid overload and mortality in critically ill patients. Achieving an appropriate level of volume management requires knowledge of the underlying pathophysiology, evaluation of volume status, and selection of appropriate solution for volume repletion, and maintenance and modulation of the tissue perfusion. In critically ill patients, in order to restore cardiac output, systemic blood pressure and renal perfusion an adequate fluid resuscitation is essential. Recent studies have shown the relationship of fluid overload with adverse outcomes hence, manage and optimization of fluid balance becomes a central component of the management of critically ill patients. Fluid overload is frequently found in acute kidney injury patients in critical care units.
