Clinical Importance of Peritoneal Pressure Dialysis

Abstract

Maron Jose*

During peritoneal dialysis, measuring intraperitoneal pressure is easy and has clear therapeutic benefits. Adult peritoneal dialysis machines, however, hardly ever measure it. This review's objective is to raise awareness of the importance of measuring intraperitoneal pressure. This measurement is performed with the patient supine before beginning the manual exchange with the "Y" system drain. The patient's liquid column height is measured from the mid-axillary line while the drain bag is raised. With typical ranges of 10 to 16 cmH₂O, intraperitoneal pressure should never exceed 18 cmH₂O. It increases the intraperitoneal volume by 1-3 cmH₂O/L at basal values that fluctuate with posture, physical activity, and body mass index.
