近年来,大输液中微粒造成的严重危害已引起人们的注意,因此,目前许多国家药典已对大输液的微粒数做出规定。例如英国药典(1973年版)规定每 ml 含2μ的微粒不得多于1000粒;5μ者不得多于100粒。美国药典第一补充本规定10μ者不得超过50粒/ml;25μ者不得超过5粒/ml。澳大利亚规定为5μ者不超过100粒;20μ者不超过4粒。测定液体微粒数有多种方法:例如英国药典采用库尔特计数器(Coulter counter)法,美国药典采用微孔薄膜过滤与电子显微镜观察计数法。库尔特计
In recent years, the serious damage caused by the particles in the infusion has drawn people’s attention. Therefore, many national pharmacopoeia now make provision for the number of particles in the infusion. For example, the British Pharmacopoeia (1973 edition) provides that no more than 1000 particles containing 2μ per ml; 5μ no more than 100 tablets. The United States Pharmacopoeia first supplement of 10μ shall not exceed 50 / ml; 25μ no more than 5 / ml. Australian regulations for 5μ no more than 100; 20μ no more than 4. There are many ways to determine the number of liquid particles: for example, the British Pharmacopoeia uses the Coulter counter method, the U.S. Pharmacopeia uses microporous membrane filtration and electron microscopy.
