ANATOMY OF THE
PERITONEUM
Theperitoneum is a
thin, semi-permeable
membrane lining the
abdominal cavity and
covering the
abdominal organs.

WHAT IS PERITONEALDIALYSIS ?
Peritoneal Dialysis (PD) is a type of renal replacement therapy that
uses the peritoneum, a thin membrane lining the abdominal cavity,
to filter waste products from the blood.
PD utilizes the peritoneum as a semi-permeable membrane to
remove excess fluids, electrolytes, and waste products from the
blood.
During peritoneal dialysis, a cleansing fluid called dialysate passes
through a catheter tube into peritoneal cavity. The dialysate absorbs
waste products from blood vessels in the lining of the abdomen,
called the peritoneum.
TYPES OF PERITONEALDIALYSIS
1. Continuous Ambulatory
Peritoneal Dialysis (CAPD)
A manual, continuous process where dialysate
is infused into the abdominal cavity and
exchanged several times a day.
Characteristics :
▪ Manual exchanges (4 - 6 times/day).
▪ Continuous dialysis (24/7).
▪ Uses a bag or container for dialysate.
▪ Requires patient or caregiver to perform
exchanges.
2.Automated Peritoneal Dialysis
(APD)
An automated process where a machine
(cycler) performs exchanges at night while
the patient sleeps. It is also called continuous
cycling peritoneal dialysis.
Characteristics :
▪ Automated exchanges (nightly, 8-12 hours).
▪ Cyclical dialysis (multiple cycles/night).
▪ Uses a machine (cycler) for exchanges.
▪ Requires minimal patient intervention
during exchanges
CONTRAINDICATIONS
1. Severe abdominaladhesions or scarring.
2. Recent abdominal surgery or trauma.
3. Active peritonitis or tuberculosis.
4. Hernias (umbilical, inguinal, or abdominal).
5. Obesity (BMI >40).
6. Severe respiratory disease

Patient Preparation:
1. Explainprocedure and purpose to patient.
2. Obtain an informed consent.
3. Reassurance patient to ally anxiety and fear.
4. Allow the client to void before catheter insertion.
5. Institute abdominal skin preparation.
6. Document the client's weight before the dialysis.
7. Take baseline vital signs.
8. During and after the procedure.
9. Monitor the level of electrolytes.
10. Obtain samples of return dialysate for culture.
11. Compare the client's weight before and after the procedure.
12. Monitor the vital signs every 30 minutes and report any deviations.
13. Provide proper positioning for the dialysate to return from the peritoneal cavity. Place t patient in
semi-Fowler's position.
14. Observe for abdominal pain and fever which can indicate peritonitis.
15. Maintain adequate nutrition and adhere to any prescribed diet. (Increase protein intake to replace
lost one during the procedure).
