Brief summary

The purpose of this study is to evaluate the application of the impedance threshold device during hemodialysis in children to optimize fluid removal, reduce the incidence of complications (such as cramps,vomiting and hypotension), and device tolerance.

Detailed description

Effective fluid removal during hemodialysis is one of the biggest challenges in children with end-stage renal disease (ESRD). Generally, children do not tolerate having more than 3-4% of their body weight removed during each dialysis session thus necessitating multiple sessions each week to ensure effective renal replacement. Excessive fluid removal is often associated with nausea, vomiting, hypotension and cramps resulting in serious complications in patient care during and immediately after dialysis as well as reduced patient compliance. The development of novel therapies to increase the amount of fluid removed during each session without a corresponding increase in the incidence of complications is therefore very important to improve quality and compliance with hemodialysis; and eventually survival of children with ESRD. The purpose of this study is to evaluate the application of the impedance threshold device during hemodialysis in children to optimize fluid removal, reduce the incidence of complications (such as cramps,vomiting and hypotension), and device tolerance.

Recruitment details

The study recruited subjects from September 2007 to February 2011. The study will be performed in the Dialysis Unit of the Division of Nephrology, Department of Pediatrics at the Children's Hospital of Philadelphia (CHOP) with informed consent.

Pre-assignment details

The study design will consist of a run-in phase, followed by a randomized, cross-over, clinical intervention phase with application of the ITD (sham or -7 cm H2O) in 20 pediatric subjects undergoing regular hemodialysis.
