Peritoneal dialysis during peritonitis
Abstract:
Peritonitis during peritoneal dialysis is the most frequent complication associated with this dialysis technique. We studied patients undergoing peritoneal dialysis when they were without peritonitis and during episodes of clinical infection. Peritonitis was associated with a significantly decreased dialysate effluent volume, increased absorption of glucose, clearance of urea and creatinine, and protein loss in the dialysate effluent. We suggest that the changes occurring to the peritoneal dialyzing surface with peritonitis might be explained by alterations in peritoneal blood flow, effective membrane surface area, or permeability.
Insights
Peritonitis significantly impacts peritoneal dialysis, reducing fluid drainage and increasing solute/protein loss. These changes suggest alterations in the peritoneal membrane
Area of Science:
- Nephrology
- Renal Replacement Therapy
- Peritoneal Dialysis Complications
Background:
- Peritonitis is the most common complication of peritoneal dialysis.
- Understanding peritonitis's effects on dialysis efficiency is crucial.
Purpose of the Study:
- To investigate the physiological changes in patients undergoing peritoneal dialysis during peritonitis episodes.
- To identify how peritonitis affects key dialysis parameters.
Main Methods:
- Comparison of peritoneal dialysis patients during infection-free periods versus during clinical peritonitis.
- Measurement of dialysate effluent volume, glucose absorption, solute clearance (urea, creatinine), and protein loss.
Main Results:
- Peritonitis was linked to decreased dialysate effluent volume.
- Increased absorption of glucose and enhanced clearance of urea and creatinine were observed during peritonitis.
- Significant protein loss into the dialysate effluent occurred during peritonitis.
Conclusions:
- Peritonitis alters the peritoneal dialysis membrane's function.
- Changes in peritoneal blood flow, membrane surface area, or permeability may explain peritonitis-induced alterations.
