本文对我院急诊病人常用的供静脉给药的22种药物、42组配伍情况,制成静脉加药输液,在超净工作台条件下,用KF—4型微粒计数器,测定了168次微粒数,结果显示输液加药后微粒虽有增加,但均在药典规定范围内。输液中加1种、2种、3种药物后所产生的微粒数分别为x_1=5.52(n_1=16);x_2=8.17(n_2=18)、x_3=10.25(n_3=8),经统计处理,三组间无显著差异(P<0.05)。本文对产生微粒的药物、注射器、操作环境等因素进行了分析。 In this paper, emergency drugs for our hospital for intravenous administration of 22 kinds of drugs commonly used, 42 groups of compatibility, made of intravenous infusion, in the clean bench conditions, with KF-4-type particle counter, measured 168 particles The results showed that after the infusion of the drug although the increase in particles, but are within the provisions of the Pharmacopoeia. The number of microparticles produced by 1, 2 and 3 drugs in the infusion solution were x_1 = 5.52 (n_1 = 16), x_2 = 8.17 (n_2 = 18) and x_3 = 10.25 (n_3 = 8) , No significant difference between the three groups (P <0.05). This article analyzes the factors that produce particles of drugs, syringes, operating environment and so on.
