Which statement best describes the recommended sequence of actions for hypotension management?

• A. Turn down anesthetic; Crystalloids; Colloids; Inotrope
• B. Inotrope; Crystalloids; Turn down anesthetic; Colloids
• C. Crystalloids; Colloids; Turn down anesthetic; Inotrope
• D. Turn down anesthetic; Inotrope; Crystalloids; Colloids

Answer: (A)

Managing hypotension in the operating room follows a stepwise approach that starts with the most reversible, least invasive factors and moves toward bedside pharmacologic support only as needed. The first action is to turn down the depth of anesthesia if the patient appears overly anesthetized, because excessive anesthetic depth commonly causes vasodilation and myocardial depression that respond quickly to lighter anesthesia. If hypotension persists after optimizing depth, next give crystalloids to address potential relative hypovolemia and to increase preload. Crystalloids are the first-line fluid due to safety, simplicity, and rapid distribution. If a patient remains hypotensive despite adequate crystalloid resuscitation and preload is still low or the patient isn’t responding to fluids, colloids can be used to achieve more effective intravascular volume expansion with smaller total volumes. Only after confirming that depth is appropriate and preload has been optimized should inotropes be considered, to improve cardiac contractility and output if there is evidence of reduced myocardial function or persistent low cardiac output despite fluids and adequate anesthesia depth. This progression minimizes unnecessary fluid administration and avoids early reliance on vasopressors or inotropes.
