(一) SD-Na在我院收治流脑中为常用药物,通常以葡萄糖注射液稀释后供静点用,对其配伍及使用方法曾做过多次实验。方法是与10%葡萄糖,5%葡萄糖、0.9%氯化钠注射液及注射用水四组液体,分别配制成0.2%、0.5%、1%、2%、3%、4%、5%SD-Na浓度,测pH值,并放置观察析出结晶时间。 1.析出结晶与药液pH值、浓度的关系四组不同浓度的配伍液,其pH值随着浓度增高而增高、在2～5%的SD-Na浓度范围内,结晶出现,则浓度高者反而时间短。例如与10%葡萄糖注射液配伍,SD-Na浓度为2%时,pH为9.0,历时90分钟出
(A) SD-Na in our hospital admitted to the brain is commonly used drugs, usually diluted with glucose injection for intravenous use, its compatibility and use of methods have done many experiments. The method comprises the following steps: mixing liquid with 10% dextrose, 5% dextrose, 0.9% sodium chloride injection and water for injection to prepare 0.2%, 0.5%, 1%, 2%, 3%, 4%, 5% Na concentration, measured pH, and placed to observe precipitation crystallization time. 1. Precipitation crystallization and liquid pH, the relationship between the concentration of four different concentrations of compatibility solution, the pH value increases with increasing concentration in the 2 to 5% of the SD-Na concentration range, the crystallization occurs, then the high concentration Instead, the time is short. For example, 10% glucose injection compatibility, SD-Na concentration of 2%, the pH of 9.0, which lasted 90 minutes out
