(1) Having to do with the peritoneum.

continuous ambulatory peritoneal dialysis
the use of an indwelling catheter with external tubing that is strapped to the body wall when not being used for infusion and drainage of the dialysate fluid.
the employment of the peritoneum surrounding the abdominal cavity as a dialyzing membrane for the purpose of removing acumulated waste products or toxins. In veterinary medicine, the main indication is acute, reversible renal failure. Certain crystalloids such as urea, creatinine and electrolytes, and some drugs, such as the salicylates, bromides and barbiturates, can be removed.
Fluid equal in osmolarity and similar in chemical composition to normal body fluid is introduced into the peritoneal cavity via a catheter. After a period of time ('dwell time') determined by the molecular weight of the substance being used as the dialyzing solution, the fluid is drained and the cycle repeated.
see abdominal lavage.
the fluid normally present in very small amount in the peritoneal cavity.
