Performance of PLR as Predicting Preload Responsiveness

Evaluation of the Correct Performance and Knowledge About the Passive Leg Raise Test to Detect a Volume Reagibility in Critical Care Patients.

We aimed to establish current practice of correct application and interpretation of the PLR in critical care patients.

The points of concern for PLR include the following: the indication and contraindication of PLR; the choice of initial position: starting from a semi-recumbent position or supine position for PLR; how to interpret and apply the changes of CO, blood pressure, and central venous pressure (CVP) to identify fluid response during PLR; and how to identify spontaneous variation and sympathetic stimulation during PLR.

Inclusion Criteria:

• All Critical care physicians of different medical disciplines

Exclusion Criteria:

• not completely responses
