Introduction
Dialysate production can be hazardous. High-concentration dialysate may cause patients to experience hypotension, headache, muscle cramps, and other symptoms. In severe cases, patients may even develop shock. Prolonged exposure to dialysate can lead to chronic inflammation and long-term dialysis complications such as carpal tunnel syndrome. Dialysate is used in both intracorporeal (e.g., peritoneal) and extracorporeal (e.g., hemodialysis) dialysis to help prevent excessive loss of body water and electrolytes.
Dialysate production poses toxicity risks. Specifically:
High-concentration dialysate may induce acute pyrogenic reactions in patients, manifesting as hypotension, headache, and muscle cramps. In severe cases, patients may even experience shock. Chronic exposure to dialysate can lead to long-term complications of dialysis, such as chronic inflammation and carpal tunnel syndrome. Moreover, malnutrition, cardiovascular disease, and erythropoietin resistance observed in patients with renal failure are directly associated with chronic inflammation, which may ultimately threaten patient survival.
Dialysate is the fluid used during hemodialysis to facilitate diffusion-based solute exchange across the dialysis membrane—on the side opposite the patient’s blood. It is an aqueous solution containing multiple ions and non-ionic substances, possessing a defined osmotic pressure suitable for either intracorporeal or extracorporeal dialysis. The primary function of dialysis—removing excess water and waste products from the patient’s blood while preventing unnecessary loss of body water and electrolytes—is achieved through the use of dialysate. Because its chemical composition closely resembles that of human plasma, dialysate is capable of performing effective dialysis.
