Cat or dog bites and scratches require prompt wound treatment, the sooner the wound is treated the better. 1, rinse the wound: use 20% soapy water (or other weak alkaline detergent) and a certain pressure of flowing water clear water to thoroughly wash and rinse the wound for at least 15 minutes. Then wash the wound with saline (also can use water instead), and finally use a sterile cotton swab to suck up the residual fluid at the wound. If the wound is deep, you can use a syringe to flush deep into the wound. 2, disinfect the wound: thoroughly rinse the wound and then rub the wound with iodophor or 75% alcohol. If the wound is more fragmented tissue, should be removed. 3, wound treatment: the wound as far as possible without sutures, and no dressing, if there is bleeding can cover the wound with a breathable dressing. Deeper wounds, heavy contamination can consider the use of antibiotics and an injection of tetanus antitoxin injection. 4, special parts of the treatment of wounds: (1) eye: wound and intraocular wounds, to flush with sterile saline, generally without any disinfectant. (2) oral cavity: oral wound rinsing should pay attention to keep the head low, so as not to rinse fluid into the throat to cause asphyxiation. (3) External genitalia or anus: the wound treatment and rinsing method is the same as that of the skin, paying attention to the direction of rinsing should be outward to avoid contaminating the deep mucous membrane.
