The process of dialysis mimics the functions of human kidneys if they have failed. The process makes use of a machine that filters and purifies the blood, keeping the fluids and electrolytes in balance. Dialysis is crucial in the filtration of waste, impurities and excess water from the body, and to control blood pressure and regulate the chemical content of sodium and potassium in the blood. It prevents waste from poisoning other nearby organs. While dialysis is a crucial treatment process, it is not a cure for kidney failure or any other ailments.
There are three different types of dialysis offered at Apollo Dialysis:
This is the most common type of dialysis, in which a hemodialyser or artificial kidney removes extra waste and fluid from the body, and filtered blood is returned to the body through a dialysis machine. The blood flow is shifted to the artificial kidney using entrance points (vascular access) to the blood vessels. The process lasts three to five hours and is performed thrice a week.
It involves surgery that implants a PD catheter into the abdomen. It filters the blood through the peritoneum, which is an abdominal membrane. A fluid called dialyse is secreted in the peritoneum which absorbs excess waste. Once the waste has been drawn, the dialyse is withdrawn from the abdomen. The process takes a few hours and is repeated several times in a day. The types of peritoneal dialysis are continuous ambulatory peritoneal dialysis (CAPD), which must be performed while the patient is awake, continuous cycling peritoneal dialysis (CCPD) which is conducted while the patient is asleep, and intermittent peritoneal dialysis (IPD), which is usually performed in a hospital, and uses the same machine as a CCPD.
Continuous Renal Replacement Therapy (CRRT)
This is used mainly for patients that suffer from acute kidney failure, and are in an intensive care unit. The process is alternatively called hemofiltration. A machine uses the process of tubing to pass the blood, and a filter then absorbs excess waste and fluids. The blood is returned to the body, along with some replacement fluid. The procedure must be performed daily, and is nearly continuous, lasting 12 to 24 hours a day.
