Abstract :
Correct estimation of peritoneal fluid volume is the prerequisite to control the infusion and the removal of dialysate solution into and from the peritoneal cavity during peritoneal dialysis. A new approach using segmental bioimpedance measurements, a special placement of electrodes, and a correction for inhomogeneous distribution of current considerably improved the estimation of peritoneal fluid volume in 11 studies with two subsequent peritoneal fluid exchanges
