Peritoneal dialysis uses the peritoneum as a semi-permeable membrane, using the action of gravity poured into the patient's peritoneal cavity preparation good dialysate through the catheter, so that on both sides of the peritoneum exist the differential solute concentration gradient, the high concentration side of the solute to the low concentrationside of the move (diffuse effect); moisture from the hypotonic side to the hypertonic side of the mobile (infiltration). By peritoneal dialysis fluid replacement, in order to achieve clear metabolites, toxic substances and correcting water, electrolyte balance disorders purpose.
Peritoneal dialysis main disadvantages are the following:
1 induced infection: the peritoneal dialysis catheter dedicated when the medium was changed to be connected to the dialysis bag, so there is the possibility of intra-abdominal infections, and to do so in any and peritoneal dialysis step, they have to wash our hands thoroughly. With current technology, peritonitis has been greatly reduced.
2 increase in body weight and triglyceride in the blood: Since the dialysis solution is to use glucose to remove excess moisture, it may be in the dialysis absorb a part of glucose, may cause the patient's weight gain, elevated blood triglycerides and other lipids , so they need proper exercise and reducing sugar intake.
Protein excessive loss: the loss of a little protein and vitamins in the dialysis process, so the need from food. In addition to maintaining the original normal eating habits, eating more fish, meat, eggs, milk and other high-quality protein, and the best source of vitamin fruits and vegetables supply the body needs.
