Which option lists tests used to monitor renal function in anesthetic patients?

• A. USG, BUN, Creatinine, and SDMA
• B. USG, Lipase, Amylase
• C. Hematocrit, Platelets, WBC
• D. ALT, AST, ALP

Answer: (A)

Assessing renal function during anesthesia relies on markers that reflect filtration and kidney structure. BUN and creatinine are traditional serum tests that indicate glomerular filtration capacity; when kidney function declines or perfusion is reduced, these values tend to rise. SDMA is a newer biomarker that can detect early renal impairment and is less influenced by muscle mass than creatinine, making it a more sensitive renal function indicator in some contexts. Ultrasound of the kidneys (USG) adds imaging information about anatomy, size, obstruction, and perfusion, helping to identify problems that could affect renal function during anesthesia. Together, these tests provide a practical set for monitoring kidneys perioperatively. The other options include markers for pancreatic, hematologic, or liver function, which do not directly assess renal status.
