Some patients are still healing after surgery, but they find that the wound is not recovering well and even have threads showing. What is this all about? Do I need to rush back to the hospital to take care of it? If the wound is not recovering well after surgery, there may be infection, edema, fat liquefaction (rupture of subcutaneous fat cells at the incision and leakage of fat droplets) or cerebrospinal fluid leakage (there is cerebrospinal fluid in the spinal canal to nourish the spinal cord, and if the canal is not fully closed and the fluid pressure is too high, it will leak out from the wound), and this should be cleaned up by a doctor as soon as possible. In addition, we must strengthen postoperative care, protect the cleanliness and dryness of the wound, change clothes and bedding in a timely manner, especially clean up urine and stool in a timely manner to prevent contamination of the wound, and strengthen our immune system. If there is still a little bit of thread exposed at the bottom of the incision after the stitches are removed, it may be that the human body reacts differently to absorbable sutures, so don’t squeeze it at this time to prevent the incision from being infected. You can disinfect the stitches with iodophor and carefully remove them, or leave them alone and they will fall off after a while. If it still doesn’t recover after a while, you should be alert and see the surgeon as soon as possible.
