The treatment for thoracic aortic coarctation is as follows: 1. bed rest and cardiac monitoring to monitor heart rate; 2. control heart rate, blood pressure, monitor urine output, and use beta-blockers, nitroglycerin, and sodium nitroprusside to lower blood pressure in combination. Heart rate was controlled at 60-75 beats/min and systolic blood pressure was controlled at 100-120 mmHg. 3. Morphine and dulcolax were given for analgesia to keep the patient quiet, and changes in urine output were observed to exclude renal artery blockage. Observe the patient’s vital signs and urine volume in the first non-surgical stage, and perform analgesic treatment, so that the patient can safely transition to the surgical stage and proceed to the next surgery early. The specific medication should be combined with the clinical situation and guided by the doctor’s face-to-face consultation.
