Diabetic kidney hemodialysis or peritoneal dialysis

Hemodialysis

Patients suffering from uremia, renal function deterioration or loss, the body can not and metabolic waste water discharged in vitro, must rely on artificial means to “dialysis”, toxic water from in vitro, to reduce the symptoms of uremia. This is hemodialysis.

Long-term hemodialysis patients should be accepted in advance “of AVF” (to use the arm surgery on the joint together arteries and veins). Patients need a two-pin, a needle is draining the blood out, the result of “artificial kidney”, another needle is a blood dialysis will return the body, so the cycle takes about four to five hours, Completed a hemodialysis.

Hemodialysis is the protagonist of “artificial kidney”, it is the use of man-made semi-permeable membrane envelope or cause tiny hollow fibers, usually from 6,000 to 15,000 Multi-tiny hollow fiber. After draining the blood from flowing through the lining of the small hollow tube, from top-down flow, and dialysis fluid (water treatment dialysis syrup +) flow through the hollow outer tube from the bottom-up flow, and blood dialysis fluid Contrary to the direction of flow, use the “proliferation of principle” can eliminate toxins, and the use of venous pressure and negative pressure, could be in excess of water removed.

Peritoneal dialysis

Peritoneal dialysis is a natural human use of the semi-permeable membrane - peritoneal, in the body for blood purification methods. Using simple surgery will be referred to as a “peritoneal dialysis catheter” hose inserted through the abdominal wall, this is the root catheter to provide peritoneal dialysis fluid out of the access road, the general adult abdominal cavity can accommodate about four liters of dialysis fluid. In dialysis fluid retention in the process of waste in the blood through the peritoneal dialysis fluid into the tiny blood vessels, these contain the waste of dialysis fluid in the abdominal cavity in the interval from the drainage out, and then injected into another bag of fresh The dialysis fluid, so the cycle every day as directed replacement of the new dialysis solution can be ruled out metabolic waste generated by.

The selection dialysis

For patients with diabetes, dialysis these two modes of choice in patients with renal failure and other similar, but in view of the body glucose metabolism disorders, diabetes patients should be based on their condition and physical condition, the doctors under the guidance of choice. Hemodialysis and peritoneal dialysis are pros and cons:

Hemodialysis than peritoneal dialysis closer to physiological state, but also in under the guidance of medical staff. However, diabetic patients often with coronary heart disease, hemodialysis patients will increase the burden on the heart. In addition, long-term hemodialysis patients do need to do arteriovenous fistula, and diabetic patients often have atherosclerosis, arteriovenous ostomy not easy success.

Peritoneal dialysis at home, can remove a convenient Zhazhen bitterness, but will lose some of peritoneal dialysis protein, and diabetic patients with nephrotic syndrome in patients with low plasma protein, easy to do peritoneal dialysis increased malnutrition. In addition, the lower resistance in patients with diabetes, peritoneal dialysis peritoneal infection occurred when the probability is higher.

As diabetic patients with cardiovascular disease often, so many doctors that the late diabetic kidney patients to choose peritoneal dialysis. However, because of peritoneal dialysis fluid usually contain glucose, if the process was Xishouruxue dialysis, blood sugar will rise. Therefore, in peritoneal dialysis patients, while doctors should be under the guidance of insulin dosage adjustments (subcutaneous abdominal or administration) so that blood sugar standards.

Another point to note that diabetic patients can easily because of severe heart and brain blood vessels and nerve disease, dialysis patients too late to affect the quality of life and survival rates. Therefore, the end result of diabetic kidney dialysis patients with renal failure start time than other kidney lead to kidney failure as early as the end. Is generally believed that when the serum creatinine> 530 mg / l, creatinine clearance <15 to 20 ml / minute should begin dialysis.
