A Study to Evaluate the Use of Lung and intra-abdominal vessels Ultrasond for Intradialytic Complications in Hospitalized Patients on Intermittent Hemodialysis


About this study

The purpose of this study is to investigate hospitalized, non-ICU patients undergoing intermittent hemodialysis (HD) to determine:

  • If the combined use of lung and intra-abdominal vessels ultrasound in volume assessment would be better for estimation of dry weight
  • If the changes of the lung ultrasound B line numbers as well as portal venous flow pulsatility and IVC diameters could predict intra-dialytic manifestations and/or complications, such as hypotension, hypertension, tachycardia, and change in oxygen requirements
  • If findings seen with a hand-held scanner are similar to a portable ultrasound scanner

Participation eligibility
