lasix and kidney injury

[lmarti10]

why is it bad to give lasix when a patient has AKI? why do some physicians order it anyway?

Benefits outweigh risk

Maybe someone can explain it physiologically?

Not to be a pill, but a quick google search will get you exactly what you're looking for that isn't anonymous and possibly erroneous.

My anonymous and possibly erroneous answer is that it depends on what is the underlying cause of the acute injury. Since acute kidney injury is defined by either a rise in serum creatinine or oliguria diuretics are an attempt to improve urine output. The problem arises in those forms of kidney injury that don't involve fluid overload. If the injury is due to toxins, ischemia, dehydration or some form of obstruction diuretics aren't going to be of much use. If, however, you are septic and in a positive fluid balance diuretics may help to correct the imbalance if there is some residual kidney function left. Especially if the amount of fluid overload is causing pulmonary distress.

If you don't want to wade through the 3 million hits when you google lasix and renal failure I recommend this article.
