Assessment of fluid responsiveness in spontaneously breathing critically ill patients
Critical Care volume 19, Article number: P39 (2015)
Introduction
One of the main challenges in critical patient management is to assess the blood volume and determine which patients will benefit from volume expansion and which patients will benefit from support with vasopressor and/or inotropic drugs. It is known that 40-72 % of critical patients respond to volume expansion with increased stroke volume or cardiac index.
Objective
To search the literature for methods assessing fluid responsiveness in spontaneously breathing critically ill patients.
Methods
The present study is a systematic literature review. We searched randomized clinical trials through a blind search performed by two independent authors in any language in the National Library of Medicine from 2009 to 2014.
Results
We selected three articles for full review and analysis, totaling 116 patients. The results are shown in Table 1.
Conclusion
This systematic review supports the beneficial effects of adopting maneuvers that amplify the hemodynamic changes, increasing the accuracy of methods to predict fluid responsiveness in spontaneously breathing critically ill patients.
