When a pheochromocytoma crisis occurs, the patient often first shows significant elevations in blood pressure, usually characterized by a rise in systolic pressure, which can exceed 200mmHg or even 300mmHg. Immediate administration of antihypertensive drugs for symptomatic treatment is necessary. Additionally, the patient may exhibit a clear hypermetabolic state, with profuse sweating, limb convulsions, and even consciousness disorders. At this point, the patient should be immediately transferred to the intensive care unit for close observation of any changes in their condition, and effective monitoring of vital signs should be conducted. Furthermore, patients should receive cardiac monitoring, blood oxygen saturation monitoring, and can be given intravenous infusions of sodium nitroprusside to rapidly reduce blood pressure. Meanwhile, ongoing observation of the patient’s condition and appropriate replenishment of blood volume are needed. (Please administer medication under the guidance of a professional physician and do not medicate blindly.)
