Finger cut by razor blade keeps bleeding, need to stop the bleeding, clean the wound, disinfect it, get a tetanus shot, check the function of the finger.
A finger cut by a razor blade that keeps bleeding needs to be stopped first to prevent excessive blood loss. Pressure can be applied to stop the bleeding first. If the wound is too big and pressure is not effective, pressure bandage or tourniquet is needed to stop the bleeding. The tourniquet should be loosened every hour for one to two minutes to prevent ischemic necrosis of the limb. Then go to the hospital to clean and close the wound, change the medicine regularly and remove the stitches.
If the blade has rust or mud, debris and other foreign objects, you need to clean the wound of foreign objects before disinfecting the bandage. Disinfection can be done by rinsing the wound with povidone-iodine or hydrogen peroxide, and then disinfecting the skin around the wound.
If there is rust on the blade or the wound is too deep, tetanus antitoxin should be injected to prevent tetanus infection. And take amoxicillin, cefaclor and other antibiotics to prevent infection.
When treating the wound, it is necessary to move the finger or test the finger sensibility to check whether the tendons and nerves of the finger are injured. Medications should be applied under the supervision of a doctor.
