dialyysiliuokseen

Dialyysiliuos, often referred to as dialysate, is a critical component in hemodialysis and peritoneal dialysis. It is a carefully formulated solution designed to facilitate the removal of waste products and excess fluid from the blood of patients with kidney failure. The primary function of dialysate is to create a concentration gradient that drives diffusion and ultrafiltration. It contains purified water, electrolytes such as sodium, potassium, calcium, and magnesium, and a buffering agent, typically bicarbonate or lactate. The concentration of these components is precisely controlled to mimic the electrolyte balance of healthy blood, preventing excessive removal or addition of essential substances during dialysis. The dialysate also contains a higher concentration of glucose than the blood in some formulations to help with fluid removal through osmosis. During hemodialysis, dialysate flows through the dialyzer, separated from the patient's blood by a semipermeable membrane. In peritoneal dialysis, the dialysate is instilled into the peritoneal cavity, where it interacts with the patient's own peritoneal membrane to draw out waste products and excess fluid. The composition of dialysate can be adjusted based on an individual patient's needs and laboratory values.
