不同浓度乙醇湿化液的简易配制法

临床上急性左心衰竭引起急性肺水肿发病急骤、病情凶险,如不及时处理,病人会有生命危险。用20%~50%乙醇湿化高流量吸氧是常用的急救措施之一,以消除肺泡泡沫表面张力,达到提高肺泡内氧分压的目的。

应用双水平正压通气联合乙醇湿化吸入治疗急性左心功能不全早期疗效观察

目的通过观察急性左心功能不全早期在常规使用强心、利尿、扩管、氧疗、茶碱等相关治疗措施的基础上加用双水平正压通气(BiPAP)联合10%乙醇湿化吸入20min治疗的临床疗效。方法 68例急性左心功能不全患者按随机号码表法分成治疗组与对照组,治疗组与对照组治疗前各项指标比较无统计学意义(P>0.05),具有可比性。2h后以两组患者治疗后呼吸、心率、氧分压、血氧饱和度恢复程度等指标进行比较。结果两组临床指标比较两组治疗前各项指标比较无显著性差异,经过治疗2h后,治疗组患者呼吸、心率、氧分压、血氧饱和度恢复程度各项指标较治疗前明显改善,治疗组疗效明显优于对照组,差异有统计学意义(P<0.05)。结论 BiPAP联合10%乙醇湿化吸入治疗急性左心功能不全疗效显著,值得临床推广应用。

Ternary System of Fe-based Ionic Liquid,Ethanol and Water for Wet Flue Gas Desulfurization

Fe-based ionic liquid （Fe-IL） was synthesized by mixing FeCl3·6H2O and 1-butyl-3-methylimidazolium chloride [Bmim]C1 in this paper. The phase diagram of a ternary Fe-IL, ethanol and water system was investigated to construct a ternary desulfurization solution for wet flue gas desulfurization. The effects of flow rate and concentration of SO2, reaction temperature, pH and Fe-IL fraction in aqueous desulfurization solution on the desulfiariza- tion efficiency were investigated. The results shows that the best composition of ternary desulfurization solution of Fe-IL, ethanol and water is 1 ： 1.5 ： 3 by volume ratio, and pH should be controlled at 2.0. Under such conditions, a desulfurization rate greater than 90% could be obtained. The product of sulfuric acid had inhibition effect on the wet desulfurization process. With applying this new ternary desulfurization solution, not only the catalyst Fe-IL can be recycled and reused, but also the product sulfuric acid can be separated directly from the ternary desulfurization system.
