The leg needs to be debrided promptly after being cut by glass. The order of debridement starts with flushing the local wound with sterile saline to rinse out the contaminants. At the same time, the wound should be cleaned to avoid residual foreign bodies and even cause bacterial infection, and then disinfected with iodophor after cleaning. Then it should be sutured, and the suture must be sutured to the bottom to avoid residual cavity and secondary bacterial infection. Because of the neatness of the glass cut open wound, and the poor blood supply to the leg. Therefore, prophylactic oral antibiotics are usually required, usually using a generation of cephalosporins or penicillins. Patients with deeper wounds usually also require prophylactic injections of tetanus antitoxin to avoid tetanus infection.
