The method of removing subcutaneous bleeding should be based on the different parts of the bleeding and the amount of bleeding, and different treatment methods should be adopted. 1.For superficial subcutaneous capillary bleeding, local gauze pressure and elastic bandage can be used for 5-10 minutes, and most of the capillary bleeding can be absorbed by itself. 2.For small subcutaneous venous bleeding, local pressure cannot completely stop the bleeding, and local skin incision is needed to remove the subcutaneous blood and local ligation of the bleeding vein. In case of small subcutaneous arterial bleeding, due to the high pressure of arterial vessels, it is necessary to cut the skin and subcutaneous tissues, fully suture the bleeding vessels, remove the subcutaneous blood accumulation, and perform a phase of wound suture.
