During the wound repair period, there are a large number of capillaries on the wound surface. Since they are newly formed, they are easy to break and bleeding is normal. At this time, if there are no symptoms of infection in the body (fever, elevated white blood cell count, etc.), oral antibiotics should not be taken and can be stopped immediately. Failure to heal within 14 days indicates that the wound is infected (this again shows that oral antibiotics cannot prevent wound infection). (Wound infection and body infection are two concepts). If the area is not large and the depth is not deep, it is recommended to use silver sulfadiazine ointment for bandaging.
