随着休克过程的进行性加重,血镁浓度进行性升高。为了探讨其进行性升高的意义。我们在家兔失血性休克模型上采用外源点滴镁来观察血镁的升高是否是促进休克不可逆发展的重要因素之一。失血性休克:股动脉放血,使血压降到40mmHg,维持该水平到贮血器内血量开始降低时,弃去贮血器里的血液,输入等量生理盐水加上右旋糖苷4mL/Kg。一组在输入的生理盐水中加 With the progressive increase of shock process, blood magnesium concentration increased. In order to explore the significance of its progressive increase. We use exogenous drip magnesium on rabbit hemorrhagic shock model to observe whether elevated serum magnesium is one of the important factors to promote the irreversible development of shock. Hemorrhagic shock: femoral artery bleeding, the blood pressure down to 40mmHg, to maintain this level to the blood reservoir began to reduce blood, discard the blood reservoir, enter the same amount of saline plus dextran 4mL / Kg . A group in the input of saline plus
