Generally speaking, there is no clinical hemostasis method which cannot be applied as the first choice, but there are different hemostatic methods for different situations. The commonly used clinical hemostatic methods are finger pressure hemostasis, pressure bandage hemostasis, tamponade hemostasis and tourniquet hemostasis. 1. finger pressure hemostasis: it refers to the use of fingers to compress the arterial vessels near the heart of the bleeding site on the bones to occlude the blood vessels and cause temporary interruption of blood flow, so as to achieve the purpose of hemostasis, which is applicable to the temporary hemostasis of bleeding in the head, neck and large arteries of the extremities. 2. pressure bandage hemostasis. It refers to covering the wound with sterile auxiliary material and then wrapping with triangular towel and bandage, which is applicable to small arteries, small veins and capillary bleeding. If there are broken bone fragments in the wound, it is recommended that after the debridement treatment, and then pressure bandage hemostasis, so as to avoid the presence of foreign bodies in the wound and aggravate the injury; 3, stuffing hemostasis method: stuffing hemostasis refers to the use of sterile cotton pads, gauze and other tightly filled in the wound, and then bandages or triangular towel pressure bandage hemostasis, often applied to the wound more limited bleeding, such as the shoulder, armpit, neck and buttocks, etc., the wound is larger and deep If the wound is large and deep, this method can also be used when acupressure to stop bleeding is not effective.
