What is the time limit for loosening the tourniquet?

When using a tourniquet to stop bleeding, there are still many things to pay attention to, so that it can truly stop bleeding and will not endanger people's health and safety. So what is the time limit for loosening the tourniquet? The reason for loosening the tourniquet is to ensure smooth blood circulation. If it is too tight, it will hinder blood circulation, and the consequences are unimaginable.

After selecting the location of the tourniquet, you should first place a cloth strip there, tighten the tourniquet, wrap it around the limb twice and tie a knot. The tightness should be appropriate, and the wound should stop bleeding. Remember the time when putting on the tourniquet. Loosen it for 1/2 minute every half hour in winter and every hour in summer, and then tie it up again. When tying again, move the part slightly up and down. Patients with severe bleeding should be sent to the hospital for treatment as soon as possible while applying a tourniquet.

Check blood circulation. After the bandage is applied, you should check your toes or fingers frequently to see if there are any dark purple spots at the ends of your fingers, and whether the body temperature in that area has dropped. If this happens, the cloth tape should be loosened, otherwise it will cause tissue necrosis over time.

Clean the wound with sterile water (boiled water), use clean fingers to gently find the deep artery, and carefully tie the artery with sterile thread. This was the first time the open wound had been touched. If the artery is completely severed, the ends may atrophy and be difficult to find. Once you are sure the artery is in a small area of ​​tissue, you can use a large needle to sew the entire area shut.

While checking whether the operation was successful, loosen the hemostatic bandage as soon as possible to find out whether the artery causing the bleeding is the only one that has been bandaged. If bleeding is still found, the tourniquet should be re-applied immediately and the search for ruptured blood vessels should continue. There are other small blood vessels in the tissues that provide the limbs with the blood necessary to maintain physiological metabolism and maintain circulation. Do not leave the tourniquet in place.

Through the above introduction, everyone should have a clear idea of ​​the time limit for loosening the tourniquet. If you can grasp the above-mentioned points and make adequate preparations, you will not encounter too many troubles and dangerous situations. In addition, attention should be paid to the correct cleaning of the wound to avoid infection by bacteria.
