Postoperative medication is also a matter of great concern to patients. The most common question is whether it is necessary to have an infusion bag or take anti-inflammatory drugs after operation. Generally speaking, non-prosthetic outpatient surgery usually does not require antibiotics, for example, double eyelid surgery, eyebrow lift surgery, pouch surgery, facial scar repair. At work, we have an experience: the influence of abusing antibiotics is quite bad! Sometimes patients will show great incomprehension when they are told that they don't need medication after operation. I even suspect that your hospital gave me an operation and didn't give me an infusion bag or bottle? Although the first possible surgical complication in the surgical agreement is infection. But the chance of real postoperative infection is very small. In my memory, at least in the last three or four years, none of this has happened. Plastic surgery with prosthetic implants requires antibiotics. Such as prosthetic rhinoplasty, mandibular augmentation, temporal augmentation and breast augmentation. It usually takes 3-5 days to use ordinary antibiotics. It should be emphasized that infection does not depend on whether antibiotics are used after operation, but on whether the patient has surgical indications, whether the aseptic operation is strict, and whether the dressing is changed on time after operation. Sometimes, such as liposuction and eye bags removal, we will use hemostatic drugs appropriately according to the situation. Usually intramuscular injection.
