Abstract:
Objective:To design an intra-abdominal pressure measuring device applied to children on peritoneal dialysis (PD), and evaluate the feasibility and safety of the application of the device.Methods:The device consisted of a three-way stopcock with extension tubing, a three-way stopcock, a manometer tube, and a "Y" system peritoneal dialysis bag. The intraperitoneal pressure of different fill volumes was measured when a child was supine and relaxed in a horizontal position. The subjects of the study were children who received PD at the Pediatric Hospital of Fudan University from May 2019 to February 2020 and had PD dialysis age of>1 month. The children's demographic and clinical information were collected. During the measurement, the child’s complaints of pain, bloating, vital signs, and catheter-related contamination were recorded. Additionally, the occurrence of dialysis-related infections and complications during the hospitalization and outcomes of PD after three months of the measurement were tracked. A scatter plot and Pearson correlation test were used to explore the correlation between fill volumes and the intraperitoneal pressure.Results:Nine PD children were included in our study. The age of the children was (8.4±4.7) years old. The body surface area is (0.84±0.29) m 2. The intraperitoneal pressure was (12.6±1.9) cmH 2O at the fill volume of 1 000 ml/m 2 and (13.8±1.9) cmH 2O at the fill volume of 1 200 ml/m 2. The measurement was smoothly and safely taken without any case of contamination and dialysis-related infections during the hospitalization. After three months of the measurement, one child was transferred to temporary hemodialysis due to the aggravation of the umbilical hernia. Conclusions:The intraperitoneal pressure measuring device is feasible and safe to perform among children with PD. It can achieve non-invasive and continuous measurement of intra-abdominal pressure, and has guiding significance for the dialysis prescription of children with PD.
