Hemorrhagic trauma refers to open injuries, such as cutting a finger while chopping vegetables or being cut by broken glass. The golden time for treatment is within 6-8 hours after injury. If not treated within this time, the risk of wound infection significantly increases.
Response: Find a sterile gauze, clean towel, or dry cloth to cover the wound; apply direct pressure to the wound without compressing the artery, as most injuries involve small veins or capillaries; elevate the injured limb above heart level, or if possible, above the head for better hemostatic effect; after the initial treatment, go to the hospital as soon as possible.
A tooth that is broken or knocked out due to trauma can damage the blood supply and nerves of the tooth, requiring prompt treatment. Ideally, it should be treated within 30 minutes, and after 1 hour, the tooth's survival rate significantly decreases.
Response: If the tooth is loose and displaced, try to reposition it and then go to the hospital; find the knocked-out tooth and gently rinse it under running water; place the tooth in cold milk or saline solution and take it to the hospital immediately. If the above conditions are not available, place the knocked-out tooth between the lip and gum and go to the hospital as quickly as possible.
