Given that there are many online consultations about postoperative wound management, but the differences in treatment modalities can lead to different postoperative wound management, I am very cautious in answering these questions for fear of giving wrong advice and delaying the patient’s healing due to my negligent knowledge of other treatment modalities. Therefore, this time only patients who had modified small incision axillary sweat gland excision surgery as an example, published a series of short articles to provide patients with postoperative medication change recommendations, for patients who had other treatments for reference only. 1. The so-called medication change is the disinfection of the postoperative wound. The scope includes bilateral axillae slightly larger than the axillary hair distribution of the surgical range. The general postoperative color of this range is dark. 2, normal post-operative wound dressing generally without alcohol or iodine volt cotton ball, using topical spray can be, each side can be sprayed three times, and then covered with two pieces of gauze, fixed with 3M medical tape can be. Wound normal healing process without medication, hanging water, or the so-called “red light”, “nano” and other external illumination treatment measures. 3, fixed without too tight, to avoid upper limb activities when the force of the tape collapse, too loose can not make the gauze cover the wound. 4.If the wound is found to have molting, exudation, pus, redness and other conditions that cannot be judged and determined by yourself, you can contact the surgeon and take photos to the surgeon by WeChat, and the surgeon will inform the relevant precautions. 5.If the wound becomes infected with pus, it needs to be treated, such as alcohol gauze wet compress, etc. After surgery, the epidermis of the incision is shed and the yellowing of the tissue in the shed area is a normal phenomenon and does not belong to the category of septic infection. 6.The first change of medication after surgery is handled by the doctor. Local patients who are inconvenienced by their own change of medication or are unsure about the wound treatment can contact the doctor to increase the number of changes appropriately, and the time and number of changes will be decided by the surgeon without charging any fees during the period. 7, foreign patients with postoperative wound problems first contact the surgeon, under the guidance of the doctor to deal with the wound, if the treatment is not good to the local regular hospital for further treatment. Do not go to the local hospital to deal with the wound without contacting the surgeon. 8. Wounds are generally removed 14 days after surgery, local patients find the surgeon to remove the stitches, foreign patients go to the local regular hospital to remove the stitches. If the wound recovery is not good, the stitch removal time should be delayed appropriately. 9. Avoid stimulating diet, alcohol and tobacco, hot springs and strenuous sports activities until the wound is completely healed. 10.Wound healing is a gradual process and the time varies from person to person. Patients need to be patient and listen to the doctor’s guidance and advice. Wound problems arising from surgery can be asked to the surgeon, as much as possible in the form of text + pictures, without interfering too much with the doctor’s private time, the doctor will reply as soon as possible.
