1, be sure to take the medicine (warfarin) on time, and don't stop taking the medicine, otherwise there is a risk of thrombosis.
2. The coagulation function must be checked regularly (INR is generally recommended to be around 2.0), and the dosage of anticoagulants should be adjusted in time according to the results, especially in the early postoperative period, when the dosage of warfarin has not been completely determined, the coagulation function will fluctuate greatly, so it must be checked every day, and a more appropriate dosage will be adjusted when leaving the hospital, but at least once a week. If INR is too low, it is easy to form thrombosis, and if it is too high, it is easy to bleed.
3. After taking warfarin for a period of time (usually about one month), INR will reach a relatively stable value, but when the physical condition changes, such as getting sick, taking medicine, getting old, etc., INR will still fluctuate. , and should review the coagulation function in time.
4. Many foods will affect warfarin. I suggest looking for more professional and detailed information to have a good look. Generally, when you leave the hospital, the hospital will give you a description of anticoagulant therapy and other materials. If not, you can ask the doctor for it. This information must be carefully studied and understood, because doctors can't always instruct patients to use drugs, and doctors in many hospitals or secondary hospitals don't really contact valve replacement, and sometimes their understanding of anticoagulation therapy is not as good as that of patients themselves. Therefore, to become a good doctor after a long illness, you must learn to take care of yourself.
