Question

A diabetic patient becomes uremic as a result of lack of control of their diabetes. About 2L of dialysis fluid instilled into the peritoneal cavity of this patient through a surgically placed catheter. The objective is to remove accumulate urea and other metabolic waste in the body. Every 4-6 hours, the fluid is emptied from peritoneal cavity and replaced with fresh dialysis fluid. The technique uses about 2 L of dialysis fluid; it does not require a dialysis machine and can be performed at home. Compare the CLCAPD in the above mentioned dwell time?

Answer 1

#. It is a continuous ambulatory peritoneal dialysis.

-four 2L exchanges of dialysate into the peritoneal cavity

-remains in peritoneal cavity for 4-6 hours(dwell time )

-occurs 7 days/week.

#. Other types of peritoneal dialysis :-

1. Automated peritoneal dialysis - uses a cycling machine for dialysate inflow, dwell and outflow according to preset times/volumes

-typical prescription is 30-minute exchanges for 8-10 hours

2. Intermittent peritoneal dialysis

-combines osmotic gradients with true dialysis

-patient usually requires exchanges of 2L of dialysate at 30-60 minute intervals, allowing 15-20 minutes of drain time

-most patients - 30-40 exchanges of 2L three times weekly are needed

-automated or manual
