Treatment
Treatment is first targeted at the specific metabolic disorder.
Acute renal failure prior to chemotherapy. Since the major cause of acute renal failure in this setting is uric acid build-up, therapy consists of rasburicase to wash out excessive uric acid crystals as well as a loop diuretic and fluids. Sodium bicarbonate should not be given at this time. If the patient does not respond, hemodialysis may be instituted, which is very efficient in removing uric acid, with plasma uric acid levels falling about 50% with each six hour treatment.
Acute renal failure after chemotherapy. The major cause of acute renal failure in this setting is hyperphosphatemia, and the main therapeutic means is hemodialysis. Forms of hemodialysis used include continuous arteriovenous hemodialysis (CAVHD), continuous venovenous hemofiltration (CVVH), or continuous venovenous hemodialysis (CVVHD).

Famous quotes containing the word treatment:
“Any important disease whose causality is murky, and for which treatment is ineffectual, tends to be awash in significance.”
—Susan Sontag (b. 1933)
“I feel that any form of so called psychotherapy is strongly contraindicated for addicts.... The question “Why did you start using narcotics in the first place?” should never be asked. It is quite as irrelevant to treatment as it would be to ask a malarial patient why he went to a malarial area.”
—William Burroughs (b. 1914)
“I will use treatment to help the sick according to my ability and judgment, but never with a view to injury and wrongdoing. Neither will I administer a poison to anybody when asked to do so, nor will I suggest such a course. Similarly, I will not give to a woman a pessary to cause abortion. I will keep pure and holy both my life and my art.”
—Hippocrates (c. 460–c. 370 B.C.)
