Our supine IPPs were higher than others published in adults. Intraperitoneal pressure has an individual value associated with body size. Greater IPP was correlated with lower daily total UF and more hernias and leakages. The measurement of IPP is a simple technique and can help with PD prescription, especially in obese patients.

Normal intra-abdominal pressure is equal to atmospheric pressure (zero). In peritoneal dialysis the introduction of intra-peritoneal liquid increases intra-abdominal pressure. In various studies it is recommended that this does not exceed 16-20cm H 2 O.
