How many days can I leave the hospital after valve replacement surgery? Can I fly on an airplane after I leave the hospital? Will the wires, temporary pacemaker wires and valves in my body be affected when I go through the security check? Generally speaking, patients can be discharged about 7 days after the valve replacement surgery when the results of the review show no problem. However, we do not advocate that patients from overseas should travel home immediately after discharge from the hospital, especially if it is a long distance, and it is generally recommended that they stay in the vicinity of the hospital for a few days to get used to the situation before they leave. In addition, many patients are discharged from the hospital when the anticoagulation index has not yet reached the standard, you can stay in the hotel near the hospital for a period of time, so that you can check the anticoagulation laboratory index at any time, and it is convenient to communicate with the doctor in charge of how to take warfarin, and the most important is that you can be familiar with and master the method of taking warfarin as soon as possible. Transportation can be by car or train. Depending on the patient’s condition, if the journey is long, it is recommended to choose a station wagon or train sleeper that can lie flat. There is no standard answer to the question of whether many patients are concerned about whether they can take an airplane, and there is certainly no problem with taking an airplane after complete recovery. However, for patients who have just been discharged from the hospital, whether it is suitable to fly home immediately depends on the specific situation of the patient, and we suggest that you consult your doctor in charge before discharge. Our advice to you is that if you had a strong reaction and discomfort to the take-off and landing process as well as the turbulence of the airplane before the surgery, we recommend that you do not choose to fly when you are just discharged from the hospital. The wires, temporary pacemaker wires, and valves in your body will not cause you any damage or trouble during the security check, so please do not worry. However, if you have a permanent pacemaker, you need to explain to the staff before going through the security check that you can’t go through the security gate and need a special security check; you can go through the security gate normally after the valve replacement surgery, and if there is an alarm, you can just explain the situation to the security staff. In addition, according to our experience, some airports will require you to produce a certificate from the hospital for patients who have just been discharged from the hospital after cardiac surgery, so we suggest you to prepare it beforehand.
