Patients who have been scratched and bleeding by a cat may have wound infection and are at risk of tetanus or rabies, and should pay attention and take certain preventive care measures. If the treatment is not timely after being scratched by a cat, the wound is irregular and there is a risk of local infection, and the patient should promptly clean the wound and stop the bleeding. Second, if the cat scratch bleeds and the wound is narrow and deep, there is a risk of tetanus bacillus infection, at which point the patient needs to be injected with tetanus serum. If rabies develops after infection with rabies virus, there is no good treatment method. Although a simple scratch will not lead to rabies, it is still recommended that patients with more serious wounds receive rabies vaccination within 24 hours, and if there is bleeding, rabies immunoglobulin or serum should be injected at the same time. Therefore, patients with severe bleeding wounds from cat scratches should be treated promptly by rinsing the wound with soap and water and disinfecting it locally before consulting an emergency room or infection unit.
