Mild bleeding usually stops by itself. For serious bleeding, if the bleeding cannot be controlled, it may lead to shock or even death. Appropriate hemostasis methods should be taken as soon as possible.
The commonly used hemostasis methods are as follows:
Pressure bandage to stop bleeding, cover the wound with gauze or clean cloth, and directly apply pressure to prevent blood flow. If necessary, add more layers of gauze, gauze will help to form a clot to prevent blood flow, and then use bandage for pressure bandage.
It is a simple and effective method to press the bleeding part with fingers to prevent bleeding, but the duration cannot be too long. Other more effective methods should be taken as soon as possible.
Tourniquet is mainly used for hemostasis in emergency. In emergency, cloth strip or belt can be used as tourniquet. After selecting the position of tourniquet, the cloth strip shall be padded at the place first, the tourniquet shall be tightened, the limbs shall be tied for two weeks, and the tightness shall be appropriate, so as to observe whether the wound is bleeding.
Tourniquet hemostasis parts: upper limb hemostasis is generally tied at the upper 1 / 3 of the upper arm, and lower limb hemostasis is tied at the upper 1 / 3 of the thigh; when binding, pay attention to protect the skin at the binding position.
The upper tourniquet needs to record time, relax the tourniquet once every hour, do not exceed three minutes each time, and use finger pressure instead of stop bleeding. If not let go, because the tourniquet will block the flow of blood, bundled Excessive time can seriously damage the tissue - even leading to limb necrosis. When you tie again, the part should move slightly up and down. For patients with major bleeding, the upper tourniquet should be sent to the nearest hospital as soon as possible.
Operation hemostasis: suture and ligation can be performed during the operation.
Postoperative: hemostasis can be achieved by using hemostatic drugs.
