采用无纺布和医用纱布折断安瓿对药液微粒污染的对比研究

摘要

目的 比较采用无纺布和医用纱布折断安瓿对药液的微粒污染情况.方法 将200支灭菌注射用水(2 ml/支)随机分为实验组和对照组,每组各100支,实验组用消毒无纺布包裹折断安瓿,对照组用医用纱布包裹折断安瓿,两组均用10 ml注射器抽吸安瓿内溶液,注入测量杯内进行检测.结果 实验组药液中的微粒量较对照组少,差异具有统计学意义(P＜0.05).结论 使用消毒无纺布包裹折断安瓿可减少对药液的微粒污染.%Objective To compare the particle pollution to the solution in the ampoule wrapped and broken by non-woven fabrics and medical gauze.Methods Totally 200 pcs of sterile water for injection(2 ml/pc) were randomly divided into the experimental group and the control group,with 100 pcs for each.For the experimental group,the ampoules were wrapped and broken by disinfected non-woven fabrics.For the control group,the ampoules were wrapped and broken by medical gauze.The solution was sucked from the ampoule with a 10 ml syringe and injected into a measuring cup for testing.Results The quantity of particles in the solution in the experimental group was less than that in the control group,and the difference was statistically significant (P＜0.05).Conclusion Wrapping and breaking the ampoule by disinfected non-woven fabrics can reduce particle pollution to the solution,and this method is easy to practice.
