简要总结
Traditional methods for intravascular volume status assessment include physical examination, raised leg test, central venous pressure (CVP) and pulmonary artery catheters occlusion pressure (PAWP). Central venous pressure and pulmonary artery occlusion pressure are invasive and associated with significant complications. More recently, a number of less invasive techniques have been introduced, but they lack standardization and reliability. Ultrasonically, inferior vena cava collapsibility can detect hypovolemia non-invasively.
详细描述
The aim of this study is that measurement of subclavian vein collapsibility index(SCV-CI) could be potential adjunct to IVC-CI where the IVC visualization is impaired or not possible .
-Finding a non-invasive reliable accurate method for evaluation of intravascular volume and response to volume resuscitation.
