In other situations, fluids are given to promote increased blood flow to the kidneys. In situations where blood loss or shock has occurred, blood transfusions may be given. Electrolyte imbalances are monitored closely. Medications can be given to lower elevated electrolytes or potassium levels. Dialysis may be used to replace the normal kidney function until the acute renal failure resolves.
Dialysis involves redirecting blood flow from the person to a dialysis machine.
The machine filters the blood and then returns it to the person. Generally, there are few side effects to treatment of acute renal failure. The complexity of the disease itself can lead to further difficulties. When dialysis is necessary, a large intravenous catheter is placed into a vein in the upper arm or chest. This can pose risks of bleeding or infection.
