Peritonitis in continuous ambulatory peritoneal dialysis patients
Abstract:
Peritonitis is the most important complication of continuous ambulatory peritoneal dialysis (CAPD). We reviewed our experience with peritonitis over a 2 1/2-year period. Our patients spent 4% of their total time on dialysis in hospital due to peritonitis. Thirty-eight percent of the episodes of peritonitis were treated without hospitalization. We evaluated the dialysate bag change technique as commonly performed with currently available devices (extension tubing and titanium Luerlock Tenckhoff catheter adapter). The aseptic techniques described for dialysis extension tubing changes appear adequate (with no increased incidence of peritonitis demonstrated shortly after an extension tubing set change). Long-term sterility is maintained at the dialysate bag puncture port and at the orifice of the dialysis catheter adapter (no positive cultures from the bag port and orifice of the titanium adapter). Etiologic diagnosis of uremia was not a risk factor predisposing to peritonitis. The incidence of peritonitis was greater among patients with less formal education and lower income. Out data suggest that patients with less formal education and of lower economic status be carefully evaluated before commencing CAPD.
Insights
Peritonitis, a complication of continuous ambulatory peritoneal dialysis (CAPD), requires hospitalization for 4% of dialysis time. Patients with lower education and income face higher peritonitis risks.
Area of Science:
- Nephrology
- Infectious Diseases
- Dialysis
Background:
- Peritonitis is the primary complication of continuous ambulatory peritoneal dialysis (CAPD).
- Understanding peritonitis incidence and risk factors is crucial for patient management.
Purpose of the Study:
- To review institutional experience with peritonitis in CAPD patients.
- To evaluate the dialysate bag change technique and identify associated risk factors.
Main Methods:
- Retrospective review of peritonitis cases over 2.5 years.
- Evaluation of aseptic techniques during dialysate bag changes.
- Analysis of patient demographics and socioeconomic factors.
Main Results:
- Patients spent 4% of dialysis time hospitalized due to peritonitis; 38% were treated outpatient.
- Aseptic techniques for bag changes were adequate, with no increased peritonitis incidence post-change.
- Long-term sterility was maintained at the dialysate bag port and catheter adapter.
- Lower formal education and income correlated with higher peritonitis incidence; uremia was not a risk factor.
Conclusions:
- The dialysate bag change technique appears safe and effective in maintaining sterility.
- Socioeconomic factors, specifically lower education and income, are significant risk factors for peritonitis in CAPD patients.
- Careful patient selection is recommended for individuals with lower socioeconomic status before initiating CAPD.
