Abstract

The fluid resuscitation of patients with acute circulatory failure aims to increase systolic volume and consequently improve cardiac output for better tissue oxygenation. However, this effect does not always occur because approximately half of patients do not respond to fluids. The evaluation of fluid responsiveness before their administration may help to identify patients who would benefit from fluid resuscitation and avoid the risk of fluid overload in the others. The dynamic parameters of fluid responsiveness evaluation are promising predictive factors. Of these, the echocardiographic measurement of the respiratory variation in the inferior vena cava (IVC) diameter is easy to apply and has been used in the hemodynamic evaluation of intensive care unit (ICU)patients. This article updates the use of IVC respiratory variation to assess fluid responsiveness and its applicability among patients with acute circulatory failure in the ICU.
