Flexion limb elevation blood circulation method refers to the case where there is a lot of bleeding in the arm or lower leg, and simple pressure dressing cannot achieve the goal of blood circulation. If there is no fracture or shoulder joint dislocation around the wrist or knee, thick cotton cloth pads or cotton towels, clothes, etc. can be placed in the elbow or knee joint, then flex the joints, and use gauze patient’s bandage to fix the joints, so that the compressed soft pad compresses the bleeding near the heart end of the main artery, thereby achieving the goal of blood circulation. Note that if there is a fracture or shoulder joint dislocation around the joint, it cannot be used.

Flexion limb elevation blood circulation method is one of the compressed hemostasis methods, mainly used for blood circulation at joint positions or around joints, commonly seen in wrist joint dislocation, shoulder joint dislocation, or patella. If there is bleeding in the axillary region below the shoulder joint dislocation, a pad can be placed in the axillary region to block it, and then the patient himself can exert pressure on the axilla, which can have the effect of compressed blood circulation. In the case of bleeding in the left axilla or patella of the wrist or knee, or surrounding areas, if there is no bandage wrapping on the scene, a relatively soft cloth can be placed around the joint, flex the joint, and then it can have the effect of compressed blood circulation.

Flexion elevation blood circulation method is one of the common hemostatic methods in clinical medical rescue, mainly used for bleeding below the patella and wrist joint. If there is no fracture and joint injury, thick padding, plastic foam, or gauze rolls can be placed in the popliteal fossa or elbow, then flex the joints, and then use triangular bandages, wide cloth bands, gauze, etc. to firmly fix them, which has the effect of compressing the main arteries of the limbs, so that blood cannot pass or pass through to reduce it, thereby controlling the bleeding at the distal part of the body, reducing bleeding, and saving lives.

Tourniquet hemostasis is generally applicable to bleeding from the main arteries of the limbs or during the entire process of limb surgery. The types of tourniquets are mainly the following: rubber tube tourniquets, extensible rubber wiping belts, and pneumatic tourniquets. The position of the tourniquet: for the upper limb, it is at the upper 1/3 of the arm; for the lower limb, it is at the middle and upper 1/3 of the root of the thigh. During the entire process of applying the tourniquet, attention should be paid to: excessive working pressure of the tourniquet or too long a duration may cause ischemic necrosis of the body. In addition, when releasing the pressure of the tourniquet, a large amount of blood flows into the affected side, causing a significant decrease in the reasonable blood flow of the whole body, which may lead to shock. Therefore, when releasing the pressure of the tourniquet, it should follow the standard of slow release-observe-slow release-observe, and not release all at once.
