库血复温后有形成份、生化及血气改变的研究

目的 通过对库血复温前后成份改变的对比观察与研究，为临床大量输入复温库血，更安全有效地抢救病人提供理论依据和有效方法。方法 将每个库血样本分为对照组和复温组。对两组血液在有形成份、生化及血气方面进行比较。结果 复温后血液红细胞、白细胞、红细胞压积、Na^ 、Cl^-、Ca^2 、氧分压、血氧饱和度无明显变化。血小板计数、K^ 、乳酸脱氢酶明显升高。血液pH、二氧化碳分压、剩余碱、缓冲碱、HCO3^-明显降低。结论 库血复温后，对血液有形成份、生化及血气的影响利多弊少，对大失血病人的急救是一种安全有效的方法。

Study on blood components,biochemical and blood gas changes of banked blood after rewarming

Objective To observe the changes of banked blood after rewarming,to offer theoretical basis and effective method for clinical massive transfusion.Methods The sample banked blood was divided into two groups:experimental group and control group.The visible components,biochemical and blood gas changes between the two groups were compared.Results The result showed that RBC, WBC, HCT, Na +, Cl -, Ca 2+ , PO 2 and SO 2 were not obviously changed. PLT count, K + and LDH were obviously increased. pH, PCO 2, BE, BB and HCO - 3 were obviously decreased. There was little harmful effect on the visible components, biochemistry and blood gas. Conclusion The method is effective to rescue the massive hemorrhagic patients.
