2. PERITONIUM
• Membrane covering abdominal cavity
• Covers almost all the intra abdominal organs
• Made of mesothelium supported by thin layer of connective tissues
• Supports the abdominal organs and serves as conduit for blood and
lymph vessels
3. PERITONIAL DIALYSIS-PRINCIPLE
• Peritoneum here acts as a semi-permeable membrane
• Unwanted fluid and solute and move from blood to dialysis solution
through the semi permeable membrane (HERE PERITONIUM)
• The process that takes place here is ultrafiltration, convection and
diffusion
4. • DIAGRAM-PASSAGE OF SOLUTE
• The diagram gives you a clear explanation
• The impure solute particles in the blood is passed through the semi
permeable membrane leaving the blood within the membrane
• The driving force is the concentration gradient between the
peritoneal dialysate and the blood
5. PASSAGE OF UNWANTED LIQUID
• The passage of unwanted liquid occurs due to the osmotic pressure
gradient and this is achieved by adding glucose to the dialysate
• The fluid is removed due to the osmotic pressure variation which is
the driving force
7. • The total set up has the following components
• 2 bags one with the dialysate and another to collect the waste from
the blood
• A hole is made in the abdomen and the dialysate is pass though it into
the peritoneum
• Now inside the peritoneum the dialysate is present and thus the
passage of the liquid through the semipermeable membrane occurs
due to the variation in the osmotic pressure and the passage of solute
is due to variation in concentration
• Thus the unwanted liquid below the kidney is taken away through the
peritoneum membrane which acts as the semi-permeable membrane
here
8. • From the peritoneum it is again taken outside through the tube to
another bag where the waste liquid is collected
• And once again the pure dialysate is sent into the peritoneum and the
process is continued
10. DIALYSATE
• The dialysate is a liquid containing sodium chloride, sodium
bicarbonate, calcium chloride, potassium chloride and magnesium
chloride are present in general and sometimes glucose may also
present
• Main function is to remove waste materials from the blood and keep
the useful materials from leaving the blood
11. TYPES OF PERITONIAL DIALYSIS
• 3 Types
• CONTINUOUS AMBULATORY PERITONIAL DIALYSIS
In this the dialysis is given to the patient very often in the daytime and
only once during the night time
12. • CONTINUOUS CYCLIC PERITONIAL DIALYSIS
In this method the dialysis is done only once in the daytime and often
in the night time
13. • DAY INTERMITTENT PERITONIAL DIALYSIS
In this the dialysis is done several times in day time alone and no need
of dialysis at night time
14. • NIGHT INTERMITTENT PERITONIAL DIALYSIS
As the name itself indicates this is done several times at night and no
need of dialysis at day time
