What is the treatment approach for pre-renal acute kidney injury?

When managing pre-renal acute kidney injury (AKI), the primary treatment approach focuses on restoring adequate renal perfusion. Pre-renal AKI is typically caused by factors that reduce blood flow to the kidneys, such as dehydration, heart failure, or systemic blood loss. Therefore, providing normal saline (or other appropriate fluids) helps to expand intravascular volume, improve renal blood flow, and subsequently enhance kidney function.

In many cases, the administration of normal saline is crucial if the patient is dehydrated or hypovolemic, as it directly contributes to elevating blood pressure and delivering necessary fluid to the kidneys. This intervention targets the underlying cause of pre-renal AKI, which is a lack of sufficient blood flow, making it key in the treatment strategy.

While optimizing blood pressure with medications may also be important, fluid resuscitation is typically the first step in managing pre-renal AKI to effectively address hypotension. Administering a foley catheter may be necessary for monitoring urinary output but does not treat the cause of pre-renal AKI. Discontinuing nephrotoxic medications may be relevant in certain clinical scenarios, but it does not apply specifically to the treatment of pre-renal causes. Hence, the focus should
