Aortic dissection is a critical disease, so we should be hospitalized immediately to control blood pressure, and perform emergency surgery or artificial stent intracavitary isolation treatment. Now your mother's operation is going well, and she will be transferred to the general ward for treatment soon. This is a very good thing.

Postoperative patients are in the recovery period of gastrointestinal function due to fasting for many days. When they can eat early after operation, they can slowly promote the recovery of gastrointestinal function with warm water, porridge, noodles and other liquid foods. When you are hungry, you can eat easily digestible food such as steamed bread, and you can also eat some fruits, such as bananas, which can promote defecation. Don't ban big oil, many families send a lot of juice, milk and so on. It's best to control it from the beginning, because these are easy to cause diarrhea. If the dissection involves mesenteric artery, intestinal peristalsis will be weak, and many patients with dissection will have constipation symptoms after operation. At this time, you should drink plenty of water and use drugs such as kaisailu to promote defecation.

After defecation is smooth and regular, you can gradually strengthen diet therapy, such as milk, lean meat, fish and other foods rich in high-quality protein, because the recovery of the body after operation mainly depends on protein. After the gastrointestinal function is fully restored, you can eat whatever you want as before.

Your mother has high blood pressure. Pay attention to control the intake of salt, give priority to light diet, and insist on taking antihypertensive drugs.

I hope my answer can help you, and I wish your mother a speedy recovery!
