资源描述

1血管损伤急救的知识管在四肢到处都是,普通体表静脉损伤局部加压止血往往就可以了,知名动脉损伤出血量大,速度快,流出的血呈鲜红色,不同于静脉损伤流出的暗红色血,且往往呈喷射性。关节处人字形包扎户外止血包扎如何现场急救止血?1.局部按压,加压包扎,指压止血后马上利用身边能利用的干净衣服毛巾等局部加压包扎,捆扎。22.环扎止血,在手指及脚趾,可以利用局部加压,也可以用橡皮筋于指(趾)根部勒紧止血,或用手指从左右侧(注意不是上下侧或手指掌背侧)指根部压住指骨,滑向手指掌侧,捏紧掌侧软组织,此法阻断手指指掌侧指动脉,可有效止血。但捆扎后需尽快至医院急诊,橡皮筋捆扎时间不能超过一小时。3.若是较大创面,局部压迫止血效果不佳时,可于上臂上 1/3 平面或大腿捆扎止血带,压力必需较高,高过人体血压收缩压 50-100mmhg 方可有效止血。注意事项:不可捆扎上臂中下段,容易压迫挠神经导致神经损伤,必需记录上止血带时间,1 小时后必需放松 10-15分钟。勿用绳索电线等捆扎,用宽布条较好。前臂及小腿不适用止血带,因有两根长骨使血流阻断不全。4.边止血,边打 120 或自行赶往医院,保持镇静。向周边的人呼救寻求帮助。
