How to Use Tourniquet?

Views:47     Author:SunnyWorld     Publish Time: 2018-10-10      Origin:Site

Tourniquet is a simple and effective method for hemostasis in the emergency treatment of limbs. It stops bleeding by compressing blood vessels to achieve hemostasis. However, if used improperly or for too long, the tourniquet can cause ischemia and necrosis of the distal limbs, resulting in disability. For this reason, the tourniquet can only be applied when the bleeding is severe and the blood cannot be stopped by other methods.The tourniquet is preferably a rubber band or a rubber tube. It is not advisable to use an inelastic tape such as a tape or a wire. The bandaging position should be above the wound (near the heart) and as close as possible to the wound. The upper 1/3 of the upper arm and the upper middle part of the thigh are good. The calf and forearm cannot use tourniquet because there are two bones and the blood vessels are just right there, the tourniquet does not act to compress the blood vessels. The middle 1/3 of the upper arm can also not use tourniquet because it may cause nerve damage and cause arm paralysis.

First Aid Method

■-  After selecting the bandaging position, the cloth should be placed at the place, the tourniquet should be tightened, and the limbs should be tied for two circles. The tightness should be appropriate to observe that the wound is not bleeding. Remember to take time on using tourniquet, relax for half an minute every half hour in the winter and every hour in the summer, and then tie it up. When you tie again, you need to move up and down slightly. For patients with major bleeding, they should be sent to the hospital as soon as possible while the tourniquet is used.

■-  Wash the wound with sterile water (boiled water) and gently locate the deep artery with a clean finger and carefully puncture the artery with a sterile line. This is the first time an open wound has been touched.

■-  If the artery breaks completely, the end may shrink and it will be difficult to find. When you are confident that the artery is in a small piece of tissue, you can use a large needle to sew the entire tissue.

■-  Check the success of the operation, loosen the tourniquet as soon as possible, and find out whether the artery that caused the bleeding is just the blood vessel that has been bandaged. If you find that you still bleed, you should immediately re-attach the tourniquet and continue to look for broken blood vessels. There are other small blood vessels in the tissue that provide the blood necessary for the limb to maintain physiological metabolism and maintain circulation.

■-  Do not leave the tourniquet in place.
