Continuous ambulatory peritoneal dialysis: a three year experience
Insights
Continuous ambulatory peritoneal dialysis (CAPD) offers good patient survival and technique success for end-stage renal failure. CAPD patients maintained satisfactory biochemical control and blood pressure on a liberal diet, with many able to work.
Area of Science:
- Nephrology
- Renal Medicine
- Dialysis Therapy
Background:
- End-stage renal failure (ESRF) necessitates renal replacement therapy.
- Continuous ambulatory peritoneal dialysis (CAPD) is a treatment option for ESRF patients.
- Evaluating the long-term outcomes of CAPD is crucial for patient management.
Purpose of the Study:
- To assess patient survival and technique success rates of CAPD.
- To evaluate the efficacy of CAPD in biochemical and blood pressure control.
- To identify common complications and their impact on hospitalization in CAPD patients.
Main Methods:
- A prospective study of 66 patients with ESRF commencing CAPD over three years.
- Monitoring of patient survival and technique success rates.
- Assessment of biochemical parameters, blood pressure, and complication rates.
Main Results:
- Two-year patient survival was 86%, and technique success was 64%.
- Satisfactory biochemical and blood pressure control was achieved with a liberal diet, often without antihypertensive medication.
- Common complications included peritonitis, catheter obstruction, postural hypotension, and weight gain, contributing to a mean hospitalization of 33 days per patient annually.
Conclusions:
- CAPD demonstrates favorable patient survival and technique success in ESRF.
- CAPD facilitates good metabolic and hemodynamic control, allowing for a liberal diet.
- Despite complications, a significant proportion of patients, including older individuals and diabetics, remained employed.
Abstract:
During a three year period 66 patients with end-stage renal failure were commenced on continuous ambulatory peritoneal dialysis (CAPD) at the Western Infirmary, Glasgow. The patient survival and the technique success rates were 86 per cent and 64 per cent at two years respectively. Biochemical and blood pressure control were very satisfactory on a relatively free diet and usually without the need for antihypertensive drugs. The complications next in frequency to peritonitis were catheter obstruction, postural hypotension and excessive weight gain. The mean hospitalisation period per patient per annum was 33 days, with half of this due to peritonitis. Despite selection criteria favouring older patients, diabetics and those with vascular complications, one third of the patients were able to work.
