The Peritoneal Dialysis (PD) is carried out by introduction to an abdominal cavity of a special dialysis fluid.
At the same time the role of a semipermeable membrane carries out a peritoneum mesothelium. Peritoneal dialysis is effective at the acute renal failure (ARF) and the hronmchesky renal failure (HRF).
For treatment of sick HPN use intermittent peritoneal dialysis and continuous out-patient peritoneal dialysis. Intermittent peritoneal dialysis, as well as a chronic hemodialysis, carry out 2-3 times a week on 9-10 h, at the same time for one session of 18-20 times there is an automatic change of a peritoneal dialysis fluid. At continuous out-patient peritoneal dialysis in difference the dialysis fluid resides in an abdominal cavity, it is replaced by the patient of 4-6 times a day.
Continuous out-patient peritoneal dialysis is applied more often in house conditions. At treatment of PAPD in comparison with a chronic hemodialysis the best control of the ABP is provided, the osteodystrophy, a polyneuropathy, anemia, a hypogonadism due to the best clearance of "average molecules" progress more slowly. Continuous out-patient peritoneal dialysis can be applied when carrying out a hemodialysis is difficult, especially at arterial hypotension, hypocoagulation, in pediatric practice, at a diabetes mellitus, heavy atherosclerosis. At HPN with the expressed overhydratation and a hyperpotassemia continuous out-patient peritoneal dialysis is not applied as unlike a hemodialysis it does not provide bystry removal of excess of water and potassium.
Continuous out-patient peritoneal dialysis is complicated by staphylococcal peritonitis which is, as a rule, sensitive to antibacterial therapy and does not demand the termination of treatment of PAPD.
