Hemostasis is an important measure to prevent shock and save patients' lives. Effective hemostasis can win precious time to transport the wounded to hospital.
1.Pressure hemostasis
If bleeding occurs, stop the bleeding first. Generally speaking, a clean dressing should be used first. If there is no dressing, a clean handkerchief, towel and clean clothes are all viable. Take the cut of forearm for example.
Press the dressing on the forearm wound and apply pressure with the bandage. The dressing covering the wound should be slightly thicker, usually in 8 to 12 layers. If you use a towel or handkerchief, it should be a little thicker and a little larger so as to cover the edge of the wound. When using a bandage to bind up, press some strength and bind up with compression.
Key points of pressure hemostasis:
1)The gauze should be thick enough.
2)Covered area should exceed the wound area.
3)Binding up with compression.
2.Digital pressure hemostasis
1)Finger trauma
Finger trauma is a common injury, especially in children. As there are more terminal blood vessels in finger, so the bleeding is more. Do not panic when finger trauma occurs. First, perform digital pressure hemostasis to stop bleeding. Since the blood vessels are on both sides of the finger, so pressing hard against the central part of both sides of the root can stop the bleeding quickly. After hemostasis, the injured part and degree of the injury, the bone and the finger nails should be checked again.
2)Palm traumatic bleeding
There are two arteries in the wrist, that is, the ulnar and the radial arteries. They are the main arteries that supply blood to the hand. Simply press the two arteries together and the bleeding in the palm can be stopped. The radial artery is located on the outside of the wrist, about 1.5 cm from the root of the wrist, where it is distinct pulsating. The inner side of the wrist is the ulnar artery. It is located in a position that is relative to the radial artery. You can stop bleeding by pressing down on the two arteries vertically.
3)Forearm traumatic bleeding
When the forearm is injured and bleeding, it can be stopped by compression of brachial artery. In the middle of the chelidon, you can feel a beating vessel, which is called the brachial artery. The brachial artery is the larger vessel that supplies the blood to the forearm. Press the peptide artery directly on the chelidon with your index finger or thumb and at the same time, press the back of the elbow. At this point, the forearm trauma of the blood will be significantly reduced.
4)The upper arm traumtic injuries
When there is upper arm haemorrhage, you can use axillary artery compression haemostasis. Unclothe the patient, in the middle of the armpit and near the medial side of the forearm, you can touch a vessle like a cord. It's the axillary vein, which contains the axillary artery and the axillary vein and you can feel the axillary artery and the pulse. At this time, two adjacent fingers of the rescuers keep perpendicular and press on the inner forearm to help stop the bleeding.
If the lesion area is large, and the bleeding in the forearm cannot be stopped even the axillary artery is compressed, then press the subclavian artery, where is 1/3 of the central superior margin of the clavicle. Press it with the thumb straight down and this will stop the bleeding.
