...with the worsening renal function, for an example: Urea 201 mg%, Creatinine 8.2 mg% and Hb 8.2 gm% but Serum K still normal 4.1 mmol/L, mostly arteriovenous (AV) fistula is needed to be created in advance for haemodialysis. The fistula matures in about 6 weeks time, then only it can be used for haemodialysis. If urgently needed then double lumen catheter in one of the large veins like Subclavian can be used for Haemodialysis.
...in the dialysis machine there is a semipermeable membrane separating the blood of the patient from the dialysis fluid composed of various substances. Through the semipermeable membrane urea, creatinine and potassium, being small molecules pass into dialysis fluid turning it into urine along with urobilinogen, water and other substances like uric acid, toxins but not the larger molecules like amino acids.
...the filtered blood is returned to the patient. Haemodialysis usually takes 3-5 hours and needs repeating about 3 times a week.
...when the kidney function goes below 10-15% of its capacity, dialysis or transplant is needed. There are two ways of doing dialysis: Haemodialysis and Peritoneal dialysis. Haemodialysis can be done through either of the 3 types of accesses: Catheter (double lumen) in any large vein like subclavian vein, AV fistula or AV graft. Among these three AV fistula is the most recommended by the nephrologists.
...Dialysis solution contains dextrose, a sugar, and other chemicals similar to those in the body. Dextrose draws wastes and extra fluid from the body into the dialysis solution.
