Which statement about diuretic management prior to surgery is supported?

• A. Continue diuretics to maintain hydration
• B. Hold diuretics prior to surgery to avoid hypotension
• C. Increase dose before surgery
• D. Switch to potassium-sparing diuretic

Answer: (B)

Managing diuretics before surgery focuses on preserving stable blood flow and blood pressure by avoiding excessive diuresis during the perioperative period. Diuretics reduce circulating volume and can cause electrolyte disturbances, while anesthesia itself can cause vasodilation and drops in blood pressure. Withholding diuretics on the day of surgery helps keep intravascular volume adequate, supporting preload and hemodynamic stability during induction and the procedure. Increasing the dose would worsen volume loss and risk hypotension, continuing them could lead to perioperative hypotension, and switching to a potassium-sparing diuretic doesn't address the immediate need to prevent volume depletion.
