(When aortic coarctation is clinically suspected, the patient should be admitted to ICU or CCU immediately, with absolute bed rest, close detection of vital signs and signs of vascular involvement, effective analgesia, sedation and oxygenation, etc. Anticoagulation or thrombolytic therapy should not be used. 1.Analgesia Once the diagnosis is clear, patients with severe pain should immediately apply a larger dose of morphine (≥5mg/time) or pethidine (≥100mg/time) intravenously, or sublingual dihydroetorphine hydrochloride (20-40ug/time). Pain relief is an important indicator that the aortic coarctation has stopped expanding, but the side effects of the above drugs should be noted. 2. Antihypertensive drugs should be applied intravenously rapidly for elevated blood pressure to control the systolic blood pressure at about 100-120mmHg under the condition of ensuring the effective circulating blood volume, which can effectively stop the continued expansion of aortic coarctation and maintain the blood supply to the heart, brain, kidney and other important organs. Commonly used drugs include uradil (100-400ug/min), esmolol (50-300ug/kg/min), labetalol (0.5-2.0mg/kg/min), etc. After the condition and blood pressure stabilize, gradually change to oral antihypertensive drugs. But generally do not apply angiotensin-converting enzyme inhibitors (captopril, etc.), because its coughing side effects may aggravate the condition, and also prohibit diazoxide and minoxidil, minoxetine and other strong antihypertensive drugs, because it can simultaneously increase myocardial contractility and heart rate, aggravating the expansion of aortic coarctation. 3, reduce myocardial contractility and heart rate can be used beta-blockers (metoprolol, etc.) or calcium antagonists (verapamil, diltiazem, etc.), the use of their hypotensive effect should be noted, etc. Control the heart rate at 60-70 beats/min while ensuring effective circulation. 4.Suppress cough and prevent lung infection. 5.Keep the bowel movement smooth Avoid elevated abdominal and thoracic pressure due to constipation, etc. Mild laxative medications such as marijuana capsules can be given. (B) Strive for surgical treatment For Debakey type I and II patients, surgery is the only way to save the patient. For Debakey type III patients, the 5-year survival rate is 50% with conservative treatment, but endovascular stent isolation has been successfully performed to increase the 5-year survival rate of type III entrapment to more than 90%. The best outcome can be achieved by the above treatment to try to get the patient through the acute phase and to operate after 2 weeks, but for those who develop further life-threatening tears in the entrapment, early surgery should be performed after adequate communication with the family to save lives.
