Peritonial dialyser

  1. 1. PERITONIAL DIALYSER
  2. 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. 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. 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. 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
  6. 6. Principles of peritoneal dialysis
  7. 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. 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
  9. 9. TYPES OF CATHETERS USED
  10. 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. 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. 12. • CONTINUOUS CYCLIC PERITONIAL DIALYSIS In this method the dialysis is done only once in the daytime and often in the night time
  13. 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. 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
  15. 15. THANK YOU
