Episode notes
Modern Definition of AKI
- Acute kidney injury (AKI) is now defined as a 0.3 mg/dL creatinine rise in 48 hours or a doubling over seven days.
- Even small rises in creatinine have significant clinical importance and link to worse outcomes.
Use Urine Microscopy for Diagnosis
- Always examine the urine under a microscope to identify muddy brown granular casts indicating acute tubular necrosis (ATN).
- Use urine microscopy as a quick, effective diagnostic tool instead of relying heavily on biochemical indices alone.
Lasix Challenge Prognostic Value
- Oliguric patients who respond to a Lasix challenge with significant urine output tend to have a better prognosis.
- This response helps predict kidney recovery and guides clinical management.
