Passive leg raising for assessment of volume responsiveness: a review
Current Opinion in Critical Care, 2017Purpose of review To evaluate the existing evidence on the passive leg raising (PLR) test for fluid responsiveness prediction. Recent findings It has been well established that either insufficient or excessive fluid administration derives in worse outcomes in critically ill patients,

Passive moment about the hip in straight leg raising
Clinical Biomechanics, 2000The purpose of this examine is to study the load-deformation characteristics of the hip in straight leg raising.An experimental study in which passive moment about the hip was determined as a function of hip angle.Straight leg raising is widely employed in clinical examination, and there is little information on its mechanical characteristics.Fourteen ...

Diagnosis of central hypovolemia by using passive leg raising
Intensive Care Medicine, 2007Suspected central hypovolemia is a frequent clinical situation in hospitalized patients, and no simple bedside diagnostic test in spontaneously breathing patients is available. We tested the value of passive leg raising to predict hemodynamic improvement after fluid expansion in patients with suspected central hypovolemia.Prospective study in four ...

Passive leg raising predicts fluid responsiveness in the critically ill*
Critical Care Medicine, 2006Passive leg raising (PLR) represents a "self-volume challenge" that could predict fluid response and might be useful when the respiratory variation of stroke volume cannot be used for that purpose. We hypothesized that the hemodynamic response to PLR predicts fluid responsiveness in mechanically ventilated patients.Prospective study.Medical intensive ...

Passive leg raising as an indicator of fluid responsiveness in patients with severe sepsis [PDF]
World Journal of Emergency Medicine, 2012 In the management of critically ill patients, the assessment of volume responsiveness and the decision to administer a fluid bolus constitute a common dilemma for physicians. Static indices of cardiac preload are poor predictors of volume responsiveness.

Comparison of passive leg raising and hyperemia on macrovascular and microvascular responses
Microvascular Research, 2013Passive leg raising is a simple diagnostic maneuver that has been proposed as a measure of arterial vasodilator reserve and possibly endothelial function. While passive leg raising has previously been shown to lower blood pressure, increase flow velocity and cause brachial artery dilation, its effects on microvascular flow has not been well studied ...

Passive Leg-Raising and Prediction of Fluid Responsiveness: Systematic Review
Critical Care Nurse, 2017Fluid boluses are often administered with the aim of improving tissue hypoperfusion in shock. However, only approximately 50% of patients respond to fluid administration with a clinically significant increase in stroke volume. Fluid overload can exacerbate pulmonary edema, precipitate respiratory failure, and prolong mechanical ventilation.

Bedside assessment of passive leg raising effects on venous return
Journal of Clinical Monitoring and Computing, 2011Passive leg raising (PLR) provides a reversible fluid-loading challenge and can be used to predict fluid responsiveness. The amount of blood volume recruited by this maneuver called stressed volume (Vs) is unknown. The present study aims to assess the quantitative effects of passive leg raising on venous return at bedside.We conducted a prospective ...

Passive leg raising for predicting fluid responsiveness: importance of the postural change
Intensive Care Medicine, 2008For predicting fluid responsiveness by passive leg raising (PLR), the lower limbs can be elevated at 45 degrees either from the 45 degrees semi-recumbent position (PLR(SEMIREC)) or from the supine position (PLR(SUPINE)). PLR(SUPINE) could have a lower hemodynamic impact than PLR(SEMIREC) since it should not recruit the splanchnic venous reservoir ...

Passive Leg Raising After Left Ventricular Assist Device Implantation
ASAIO Journal, 2019Left ventricular assist device (LVAD) implantation is a common procedure in patients with end-stage heart failure. Although optimal fluid management is essential for acceptable postoperative treatment, it is critical to identify which patients will benefit from fluid administration.
