Lidocaine local anesthesia requires skin cleansing before surgery. Because no preoperative skin cleaning, disinfection, although the operation itself and postoperative recovery has no effect, but easy to cause infection in the operation area.
Common local anesthesia procedures include cyst excision, lipoma excision, abscess incision, cosmetic orthodontic surgery, and so on.
If the skin of the surgical area is intact and not infected, the skin can be cleaned and sterilized before local infiltration anesthesia is given.
If the skin in the operated area is broken, infected, etc., the skin should not be cleaned by oneself to prevent negative consequences. Preoperative disinfection is required, and local infiltration anesthesia should not be performed through the broken skin or infected area.
In conclusion, the skin needs to be cleaned before surgery. If you can communicate with the surgeon, you should strictly follow the surgeon’s instructions and recommendations, and medications should be applied under the guidance of the doctor.
