Summary
Continuous ambulatory peritoneal dialysis (CAPD) does not impact lung function. Furthermore, pulmonary function does not affect the lymphatic absorption within the peritoneal cavity in CAPD patients.
Area of Science:
- Nephrology
- Pulmonology
- Physiology
Background:
- Continuous ambulatory peritoneal dialysis (CAPD) involves instilling dialysis solution into the peritoneal cavity.
- Potential interactions between dialysis solution volume, intraperitoneal pressure, and pulmonary function are not fully understood.
Purpose of the Study:
- To investigate whether dialysis solution volumes in CAPD patients affect pulmonary function.
- To determine if pulmonary volumes influence lymphatic absorption from the peritoneal cavity.
Main Methods:
- Ten CAPD patients underwent lymphatic absorption measurement, intraperitoneal pressure assessment, and spirometry with a full and empty peritoneal cavity.
- Measurements included cumulative lymphatic absorption over 4 hours and hydrostatic intraperitoneal pressure.
Main Results:
- Spirometry results showed no significant difference between a full and empty peritoneal cavity.
- Pulmonary function measurements did not correlate with lymphatic absorption or intraperitoneal pressure.
- Lymphatic absorption and intraperitoneal pressure values also did not correlate with pulmonary volumes.
Conclusions:
- CAPD does not appear to interfere with the pulmonary function of patients.
- Pulmonary function does not influence the lymphatic absorption from the peritoneal cavity in CAPD patients.
