Lung ultrasound during hemodialysis: the role in the assessment of volume status.

Objective Fluid balance is important in patients undergoing hemodialysis. “Dry” weight is usually estimated clinically, and also, bioimpedance is considered reliable. Ultrasonography of inferior vena cava (IVC) estimates central venous pressure, and lung ultrasound evaluates extravascular (counting B-lines artifact) lung water. Our study was aimed to clarify their usefulness in the assessment of volume status during hemodialysis.
