Before anesthesia in renal disease, dehydration should be corrected.

• A. Correct dehydration before anesthesia
• B. Do not correct dehydration
• C. Dehydrate further
• D. Dehydration ignored

Answer: (A)

Correcting dehydration before anesthesia is essential because dehydration lowers effective circulating volume and renal perfusion. In patients with renal disease, this reduced blood flow to the kidneys increases the risk of prerenal injury and perioperative acute kidney injury, especially once anesthesia is induced and can cause vasodilation and further drops in blood pressure. Restoring euvolemia with carefully guided fluid therapy helps maintain stable hemodynamics, preserves urine output, and protects renal function during the perioperative period. Of course, monitor closely to avoid fluid overload, but the priority is to correct dehydration to optimize renal perfusion before anesthesia.
