Aortic coarctation type b should be treated with intravenous drugs to control blood pressure and heart rate as well as to improve clinical symptoms, with continuous monitoring during treatment. Aortic coarctation can be further categorized into type a and type b, of which type b is relative and can be treated with drugs. Firstly, blood pressure and heart rate need to be controlled. For those with severe elevation of blood pressure, intravenous nitroprusside should be administered and beta receptor receptor blockers such as bisoprolol and metoprolol should be applied in combination. If there is obvious chest pain, intravenous morphine can be given to treat the relief, so as not to aggravate hypertension with chest pain. At the same time, attention should also be paid to strict bed rest, in order to prevent constipation, the diet should be based on fresh fruits and vegetables. If necessary, the use of hemp pill, aloe vera capsule, etc. can be recommended by the doctor to promote defecation. During conservative treatment of aortic dissection type b, monitoring should be strengthened to detect heart rate, blood pressure and urine output, and emergency surgery should be considered if it is extremely unstable.
