dialyysinestettä

Dialyysinestettä, also known as dialysis fluid or dialysate, is a crucial component in hemodialysis and peritoneal dialysis treatments for individuals with kidney failure. It is a carefully formulated solution that facilitates the removal of waste products and excess fluid from the blood when the kidneys are no longer able to perform these functions adequately.

The primary purpose of dialyysinestettä is to create a concentration gradient across a semipermeable membrane, allowing for diffusion and ultrafiltration. It typically contains purified water, electrolytes such as sodium, potassium, calcium, and magnesium, and a buffer like bicarbonate or lactate. The specific composition is tailored to the patient's needs and is adjusted to correct electrolyte imbalances and acid-base disturbances.

During hemodialysis, dialyysinestettä flows on one side of the dialyzer membrane, while the patient's blood flows on the other. Waste products from the blood, such as urea and creatinine, diffuse across the membrane into the dialysate due to their higher concentration in the blood. Excess fluid is removed through ultrafiltration, driven by a pressure gradient.

In peritoneal dialysis, dialyysinestettä is introduced into the peritoneal cavity. The peritoneal membrane acts as the semipermeable barrier, and the dialysate remains in the cavity for a set period, allowing waste products and excess fluid to move from the blood into the dialysate. The used dialysate is then drained and replaced with fresh solution. The careful balance of ingredients in dialyysinestettä is essential for safe and effective kidney replacement therapy.
