After each surgery, patients always ask, “Why are the bandages so tight? When can I take a shower? How many days will it take to remove the bandage?” We know that minimally invasive surgery has a small incision through which the rotary cutter used in surgery reaches the back of the lump and removes the lump cleanly through repeated cuts. This means that there is no way for the surgeon to see the wound under direct vision, and even if it bleeds, it cannot be ligated or electrocauterized as in traditional surgery. The only way to stop the bleeding is to apply pressure. The surgeon then places a large amount of gauze on the patient’s incision site, outside the skin on the surface of the lump, and then ties the elastic chest band in place in order to secure the gauze so that they do not move. When the time comes to remove the chest band, it is important not to engage in strenuous activities for 2 weeks after surgery. The surgeon will usually instruct the patient to keep the compression bandage on for 3-5 days after surgery. If you remove the chest strap too early, the gauze will fall off and it is basically impossible to wrap it back to its original shape. Although the chest strap can be wrapped tightly, the hole left after the lump is cut is still not pressed and will bleed if you move around a little more. If you bleed a little, a hematoma will form, if you bleed a lot, a scary petechiae will form, and if you bleed more, you may go into shock. We had two such patients in the clinic today. A patient less than 2 days after surgery, felt the wound pain, want to open to see, go to other hospitals to see the emergency room, the result of the elastic chest band open to watch the formation of a hematoma, see the emergency doctor actually have not seen such a situation, will not be bandaged. This time curiosity was satisfied, and the hematoma was not going to go away. The blood left the vessel and quickly formed a solid like tofu, and it was too difficult to pump it out. Another patient was a hard-working aunt who, once she arrived 3 days after surgery, took the chest strap off on time and then did a big job of brushing dishes, doing laundry, cooking and mopping the floor. 1 week after the follow-up appointment, the photos were taken and shown to her, and she surprised herself. So, sometimes you can’t work too hard, when it’s time to take a break, you have to take a break! Also, if you love cleanliness, you should start bathing 1 week after surgery, but don’t rub hard!
