Mainly about hemostatic methods for surgical hemostasis: 1, compression hemostasis, with a certain pressure to make the vascular rupture narrow, or rupture of the blood vessels closed, at this time platelets, fibrin, red blood cells can quickly form thrombus, rupture bleeding to get hemostasis, more extensive blood seepage can be relatively warm saline gauze, is 50 ℃ -60 ℃ warm gauze compression hemostasis, compression hemostasis can also be used gauze filling method. Only in the case of various other hemostatic methods are ineffective, gauze compression hemostasis, 3-5 days before gradually removed; 2, ligature hemostasis, there are simple ligature hemostasis, and suture hemostasis two methods; 3, electrocoagulation hemostasis, through the current electrocautery to make tissue contact hot spot heat generation, causing blood coagulation; 4, local drug hemostasis, mainly traumatic bleeding, commonly used drugs such as gelatin sponge, fibrin Gum, hemostatic gauze or hemostatic drugs to stop bleeding; 5, vascular blocking and repair, using the principle of tourniquet to stop hemorrhage in surgery, prevention of bleeding is also available hand block or vascular blocking band, which is to block the main blood supply vessels in the process of extremity surgery, important vascular damage when necessary, parallel vascular repair; 6, to promote blood coagulation, vascular wall plunge and achieve the effect of hemostasis; 7, orthopedics Bone marrow bleeding during surgery, use bone wax to achieve hemostasis, brain surgery can be used to stop bleeding with silver clips.
