止血带使用方法
Use of tourniquet
原理概述
Principle overview
止血带止血是用于四肢大出血急救时简单、有效的止血方法,它通过压迫血管阻断血行来达到止血目的。但如使用不当或使用时间过长,止血带可造成远端肢体缺血、坏死,造成残废,为此,只有在出血猛烈,用其它方法不能止血时才能应用止血带。
Tourniquet hemostasis is a simple and effective hemostasis method for emergency treatment of massive hemorrhage of extremities. It achieves the purpose of hemostasis by oppressing blood vessels and blocking blood flow. But if used improperly or for too long, tourniquet can cause distal limb ischemia, necrosis and disability. Therefore, tourniquet can only be used when bleeding is severe and other methods can not stop bleeding.
止血带以橡皮条或橡皮管为好,不宜用布带、电线等无弹性的带子。绑扎位置应在伤口的上方(近心端),并尽量靠近伤口,以上臂的上1/3和大腿上中部为好,小腿和前臂不能上止血带,因该处有两根骨头,血管正好走在两骨之间,上止血带起不到压迫血管的作用。上臂的中1/3部位亦不能上止血带,因它可能引起神经损伤而致手臂瘫痪。
The best tourniquet is rubber band or rubber tube. It is not suitable to use inelastic tape such as cloth band and wire. The position of ligation 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 middle of the thigh are better. The tourniquet can not be placed on the lower leg and forearm, because there are two bones in this place. The blood vessels just walk between the two bones, and the upper tourniquet can not compress the blood vessels. No tourniquet can be placed on the middle third of the upper arm, which may cause nerve injury and paralysis of the arm.
急救方法
first aid
选定止血带的部位后,应先在该处垫好布条,把止血带拉紧,缠肢体两周打结,松紧要适宜,以观察伤口不出血为度。上止血带要记好时间,冬天每隔半小时、夏天每隔1小时要放松半分钟,然后再绑起来。再绑时部位要上、下略加移动。对大出血病人,应在上止血带的同时,尽快送医院治疗。
After choosing the location of tourniquet, we should first lay cloth strip in this place, tighten the tourniquet, tie the limbs for two weeks, tighten it appropriately to observe the wound does not bleed. The tourniquet should be kept in mind. It should be relaxed for half a minute every half hour in winter and every hour in summer, and then tied up. When re-binding, the position should be slightly moved up and down. Patients with massive hemorrhage should be hospitalized as soon as possible while wearing tourniquet.
