Which preoperative assessment is prioritized when preparing a patient for pheochromocytoma surgery?

• A. Urine Ketones
• B. Blood Type
• C. Hemoglobin
• D. Blood Pressure

Answer: (D)

Managing pheochromocytoma surgery hinges on avoiding dangerous blood pressure surges caused by catecholamine release during tumor manipulation. The most important preoperative assessment is blood pressure because it directly reflects the risk of intraoperative hypertensive crises and guides optimization with alpha-adrenergic blockade and careful volume status. By evaluating and achieving stable blood pressure before surgery, you reduce the chance of massive blood pressure spikes when the tumor is handled and set up safer anesthesia and hemodynamic management, including appropriate use of alpha-blockers (and beta-blockers only after adequate alpha-blockade) and ensuring euvolemia. While other data like blood type or hemoglobin can be useful for transfusion planning or overall health, they don’t address the primary perioperative hazard in this scenario. Urine ketones are not a central factor in preparing for pheochromocytoma surgery.
