Dialysis cannulation generally refers to intravenous cannulation. Fistula and IV cannulation are both ways to perform hemodialysis. It is recommended to prioritize fistula because cannulation has more side effects than fistula, such as infection and thrombosis.
Fistula is a surgical procedure to reconstruct veins and arteries, usually for chronic renal failure requiring long-term hemodialysis treatment of kidney disease patients.
Cannula is artificial temporary to take venous puncture, usually temporary emergency use, such as the occurrence of acute kidney injury, drug poisoning, etc., resulting in renal function within a short period of time, and the use of patients with fewer times.
It is recommended to prioritize fistulae for dialysis compared to cannulae because cannulae are prone to infection, thrombosis and venous stenosis.
Patients who need hemodialysis should choose the appropriate method for hemodialysis as well as other renal replacement therapies under the guidance of professional doctors and according to their own conditions to prevent further development of their conditions.
