Ketorolac—like most NSAIDs—can affect kidney function, decreasing renal plasma flow and causing a dysfunction in salt and water balance. Postoperative patients may have activity limitations (eg, the young healthy patient on crutches). Factor in kidney damage from presurgical/outpatient NSAID use (which is usually reversible) and dehydration due to decreased fluid intake and nausea, and AKI is a real danger.
With the opioid crisis at the forefront of national health news, nonnarcotic alternatives for pain control are much in demand. This puts a whole new population at risk for AKI. Educate patients and their families about preventive measures, such as controlling nausea, maintaining hydration, and monitoring urine output. Fever, flank pain, or any untoward symptoms should be reported. Remember, AKI may be more common in the older patient with diabetes—but it can occur in anyone. —EA
