Sebaceous nevus excision is a common outpatient procedure, but it is still a relatively time-consuming and laborious process for patients with small children. For the convenience of parents of children with sebaceous nevus, some precautions are described. I. Surgery appointment Normally you should bring your child to the outpatient clinic in person, the main purpose of which is to clarify the diagnosis and evaluate the way, method and number of excisions for the surgery. However, since many children are not from Beijing nowadays, in order to reduce the burden on each family, you can make a clear diagnosis in the dermatology department of a local tertiary care hospital, do a good pre-operative examination (mainly infection screening and coagulation screening), and upload photos of your child’s skin lesions. Second, pre-operative preparation First of all, the child’s spirit. You can tell your child: we have to remove this thing, you are brave, mommy and daddy believe in you. Tell the child that the procedure is to take some syrup first and then a small injection. The second is physical. You should not operate when you are unwell, such as when you have a cold or fever and diarrhea, and you can postpone the operation by calling the operating room. The purpose of going to bed later the night before surgery and getting up earlier that day is to make your child sleepy and easy to sleep. We will give your child a sedative (or a sedative enema) before surgery and wait until your child is asleep before surgery. Sedation is administered according to the child’s weight, so the exact weight should be measured before the surgery. You can pre-shave your head before coming to surgery to facilitate sterilization and dressing application. Third, the day of surgery Do not feed milk, meat, eggs and other foods that are not easily digested and absorbed within 4 hours before surgery, and do not eat within 2 hours before surgery, you can drink drinks sugar water, etc. You can come to the operating room some time in advance to weigh, take medicine, drink medicine (or enema), and give injections. IV. Postoperative precautions 1. Observe for half an hour after surgery, and leave the hospital if there is no abnormality. The child may continue to sleep for 2-3 hours, pay attention to let him sleep on his side to prevent choking and coughing after the eruption. 2, generally 3 days after surgery to change the medicine, the main purpose is to observe the condition of the wound. If the child is out of town, it is best to change the medicine once for safety before going home. Do not fly within 24 hours after surgery to prevent postoperative bleeding from occurring. 3, keep the wound clean after surgery, do not do strenuous exercise, do not get wet. During the healing process there will be a certain itchy feeling, be sure to discipline your child not to scratch. 4.In order to reduce the degree of post-operative scarring, you can use Mepi-tip, 3M no-sew tape or skin de-tensioner after stitch removal. Insist on using them for more than 3-4 months. V. Follow up In order to ensure the smooth recovery of the child, review in time.
