临床常用输液的渗透压测定

Measurement of the osmotic pressure of clinical common injection

测定输液的渗透压，在向临床提供选择性数据的同时，也是对输液及其生产的质量考查。作者用冰点下降法测定了几种常用输液的渗进压（ｋＰａ），其算术平均值分别是：０．９％氯化钠输液为６４６．８５±１４．５１；５％葡萄糖输液为５８４．９９±１４．５１；１０％葡萄糖输液为１２７０．０３±１０．６９；０．２％甲硝唑输液为５９４．１６±１２．９９。

Measuring the osmotic pressure is not only to provide selective data but also tocheck the quality of injection.We measured the osmotic pressure of some common injection withcryoscopic method.Their arithmetic averages(kPa)are respectively:0.9%Injectio Natrri Chlori-di,646.85±14.51;5%Injectio Glucosi,584.99±14.51;10%Injectio Glucosi,1270.03±10.69;0.2%Injectio Metronidazoli,594.16±12.99.
