Renal Failure in ICU




What is meant by converting oliguric to non-oliguric acute renal failure?

This concept is much misunderstood. A diuresis does not mean a better outcome, just an easier to manage patient. If the patient responds to diuretics given in this way, they probably have less severe real injury. It is easier to look after a patient who is putting out a lot of urine in ICU, than one putting out none: i.e. edematous, bloated, hard to oxygenate and hyperkalemic. Moreover, this process may save money by reducing the need for dialysis, with itís attendant risks. One must be cautious, however in using this strategy, as volume depletion may result, and hypotension may result from reduced preload and the venodilatory effects of these drugs. High doses of furosemide can cause ototoxicity.
