1.Is it normal for the skin around the wound to become woody? A: “Tightness, sinking, numbness, pain” around the wound is basically the normal reaction after surgery, with the extension of time, the scope and degree of discomfort will slowly reduce, 2-3 months generally return to normal. If the discomfort worsens, you should promptly go to the hospital for a review. 2.Do I have to go back to the hospital for wound dressing change? A: Not necessarily, you can change the medication in the nearby hospital and school hospital, if the doctor thinks there are problems with the wound, healing is not good, promptly back to the hospital for follow-up. If conditions allow, the stitches can also be removed in the nearby hospital. 3.My bed is on the top bunk, can I climb to the top bunk to sleep after surgery? A: Due to the influence of the intraoperative position and the pain of the postoperative drainage tube. There will be stiffness and pain in the shoulder joint on the operated side, so it will be difficult to climb to the top bunk. You should actively rehabilitate and move the shoulder joint 1 day after surgery, and slowly exercise after discharge. In most of them, after discharge from the hospital with extraction, the activity is not greatly affected, and if you do have discomfort, you have to contact to transfer to the lower bunk. Active rehabilitation, the activity of the shoulder can return in a short time. 4.Do I need to go back to the university hospital for a few more days after discharge? A: Minimally invasive pneumothorax surgery is not very traumatic, and the main postoperative discomfort comes from the chest tube, which is usually relieved soon after the chest tube is removed. After being discharged from the hospital, if you are nervous about the course, you can go to the classroom to listen to the lecture or study, just pay attention to rest and don’t be too tired. 5.Can I prevent the recurrence of pneumothorax by eating fatter? A: It is true that pneumothorax is more common in people with thin and tall body type. However, the specific reason for the formation of pneumothorax alveoli is not very clear, and the more agreed view is that the lungs are stretched by the rapid growth of height during adolescence, and the force is greatest at the tip of the lungs, so the lungs are easily pulled out of the alveoli, and then the alveoli rupture to form a pneumothorax. Therefore, theoretically, eating fat can neither make the alveoli disappear nor prevent new alveoli from being created. Therefore, it is unlikely to prevent the recurrence of pneumothorax. In fact, there is no clear data to support this claim.
