Intraperitoneal pressure measurements in children on peritoneal dialysis: a review and European practice survey

Area of Science:

• Nephrology
• Pediatric Dialysis
• Intraperitoneal Pressure Management

Background:

• Adequate dialysate volume in peritoneal dialysis (PD) is critical for solute/fluid removal but can increase intraperitoneal pressure (IPP).
• Limited evidence exists on acceptable IPP upper limits and associated complications in pediatric PD patients.
• Current practices for measuring IPP (IPPM) in children vary significantly across European centers.

Purpose of the Study:

• To review current knowledge on IPP in pediatric PD.
• To highlight the need for standardized three-point IPPM for valid scientific data collection.
• To emphasize the uncertainty surrounding IPPM's role in improving pediatric PD outcomes.

Main Methods:

• Narrative review of existing literature on IPP and IPPM.
• Analysis of a practice survey from 47 European pediatric dialysis centers regarding IPPM protocols.
• Discussion on the rationale for standardized IPPM and future technological needs.

Main Results:

• 68% of surveyed centers routinely perform IPPM, but methods, limits, and interpretations differ widely.
• Significant variability exists in the frequency, mode, and interpretation of IPPM results.
• The role of IPPM in improving outcomes for children on PD remains uncertain.

Conclusions:

• Standardized three-point IPPM is essential for generating reliable data on the relationship between IPP and patient outcomes.
• Advanced, continuous IPPM technologies are needed to improve understanding of IPP's impact.
• Further research, including registries and prospective studies, is required to clarify IPPM's role in pediatric PD.
