Beijing Tongshantang hospital:what is dialysis?2017-05-27 10:48
The dialysis used in medicine can be divided into two groups: hemodialysis and peritoneal dialysis
Hemodialysis: hemodialysis, referred to as hemodialysis, popular argument also known as artificial kidney, kidney wash, is a blood purification technology of its use of semi-permeable membrane principle, through the proliferation of various harmful and excess metabolic waste And too much electrolyte removed from the body, to purify the blood of the purpose, and to achieve the purpose of correcting water and electrolyte and acid-base balance. Most of the 500,000 patients who rely on dialysis to survive in the world are hemodialysis. Hemodialysis to reduce the symptoms of patients, prolong survival have a certain significance.
Peritoneal dialysis peritoneal dialysis is used as a semi permeable membrane of peritoneal dialysis fluid, will be prepared by the catheter into the peritoneal cavity of patients with gravity so that the concentration gradient in the peritoneal solute solute exists on both sides, one side of the high concentration to low concentration (dispersion); side moving water from the hypotonic move to the side (hypertonic osmosis). The peritoneal dialysis solution is constantly replaced so as to remove the metabolites and toxic substances in the body and rectify the disorder of water and electrolyte balance.
Peritoneal dialysis shortcomings: induced infection: due to peritoneal dialysis catheter in the exchange and dialysis bag to be connected, so there may be abdominal infection, so doing any and peritoneal dialysis treatment-related steps, must first thoroughly wash Net hands. For new technologies, the incidence of peritonitis has been significantly reduced.
Weight and blood triglyceride increase: the dialysis solution is the use of glucose to remove excess water, it may be absorbed in the dialysis of some of the glucose, may increase the weight of patients, blood triglycerides and other lipids, so Need appropriate exercise and reduce sugar intake.
Too much protein loss: in the process of dialysis will lose a little protein and vitamins, so need to add from the food. In addition to maintaining the original normal eating habits, but also intake of some fish, meat, eggs, milk and other high-quality protein, and the best source of vitamins for fruits and vegetables, supply the body needs.
