In suspected aortic dissection, what is the immediate management priority?

Immediate stabilization for suspected aortic dissection centers on rapidly reducing the force driving the tear—the shear stress on the aortic wall. The best first move is IV beta-blockade to promptly lower heart rate and systolic blood pressure, minimizing ongoing damage. Once heart rate and BP are controlled, proceed with emergent imaging (CT angiography or equivalent) to confirm the diagnosis and determine the dissection type for definitive management planning. Analgesia may be used to blunt sympathetic drive, and prepare for surgical consultation if the dissection involves the ascending aorta. Avoid thrombolysis or anticoagulation, which can worsen bleeding, and don’t rely on a nonurgent scan when time is critical. Target a heart rate around 60 bpm and a systolic BP of roughly 100–120 mmHg as stabilization goals.
