What is the purpose of 0.9NS 1L @80ml/h for someone with MI and renal failure? Hydration? Aren't fluids restricted in ARF?

I think you are confusing ARF with CRF.

Hi, Izminska, and welcome to allnurses! :welcome:

Normal saline is an isotonic solution that is primarily given to maintain a patient's hydration and to replace sodium and chloride. Here is a chart of common IV solutions and their uses: [attach]5949[/attach]

Acute renal failure occurs in 3 stages:

oliguric phase
- lasts from days to weeks; urine output is less than 400 mL/day; there is fluid volume excess, azotemia and electrolyte imbalances, intrarenal vasoconstriction occurs, there is cellular swelling in the kidneys with neutrophils adhering to the capillaries and venules causing medullary hypoxia; hypoperfusion; all this leads to cellular injury and necrosis of nephrons

[*]diuretic phase

the kidney function begins to recover and urine output gradually increases with improved glomerular filtration rate although tubular transport systems continue to be abnormal

[*]recovery phase

there is a gradual return to normal or near normal renal function that occurs over a 3 to 12 month period

Fluids are not necessarily restricted in ACF. It depends on what phase of ACF the patient is in and what is going on with their electrolyte status as well. If dialysis is being done, overhydrating the patient is not a concern because excess fluid will be removed during dialysis treatments. Sodium and chloride are electrolytes that work together in the body so if the level of one drops, so will the other. They are also tied to many bodily functions and work in conjunction with other electrolytes so their levels must be maintained.
