院前急救止血带安全有效压力的探讨

目的:探讨院前急救上下肢止血带安全有效压力.方法:检测300例正常人上肢和下肢使用5 cm宽的气囊止血带,使用不同压力阻断肱动脉和股动脉血流,记录阻断血流的压力;并记录性别、年龄、上臂周长、大腿周长、收缩压等影响止血带压力的诸多因素,测得结果代入多元线性回归方程,计算与止血带压力的关系.结果:上肢止血带安全有效止血压力为收缩压±80 mm Hg,下肢止血带安全有效止血压力为收缩压±200 mm Hg.结论:收缩压±80 mm Hg和收缩压±200 mm Hg的压力为院前急救上下肢止血带的安全有效压力.

Study on the safe and effective pressure of tourniquet for pre-hospital emergency treatment

Objective: To discuss the safe and effective pressure of upper and lower extremities tourniquet for pre-hospital emergency treatment.Methods: 300 health people who used 5cm airbag tourniquet were examined,using different pressure to break blood flow of brachial artery and femoral artery and the pressure to break blood flow was recorded,and the other factors to affect the tourniquet pressure such as gender,age,upper arm circumference,thigh circumference and systolic pressure were also recorded.The measuremen...
