What general form of blood pressure disorder can be caused by anesthesia medications?

• A. Hypertension
• B. Hypotension
• C. Orthostatic Hypotension
• D. Hypertensive Crisis

Answer: (B)

The main idea is that anesthesia drugs commonly depress cardiovascular function and cause vasodilation, which lowers blood pressure. This leads to a general form of blood pressure disorder: hypotension. In the operating room, agents like propofol and many inhaled anesthetics reduce systemic vascular resistance and can directly depress the heart, resulting in a drop in mean arterial pressure. Orthostatic hypotension is a specific, position-related type of low blood pressure, not the typical perioperative effect of anesthesia overall. Hypertension or a hypertensive crisis aren’t the usual effects produced directly by standard anesthesia medications, though BP can rise transiently for other reasons.
