目的了解经不同方式处理后的肠外营养液的细菌学差异。方法将静脉药物配制中心配制完毕的三升袋随机分为A、B、C 3组,碘伏消毒螺旋帽部分两次。A组用无菌纱布包裹螺旋帽部分,B组用无菌治疗巾包裹整个三升袋,C组不做特殊处理。遵循无菌操作原则,在配制完毕和输注完毕后分别取2~3 ml标本进行细菌学培养,48小时后观察3组菌落数是否有差异。结果 3组均未培养出细菌。结论配制完毕的三升袋在运送途中及输注过程中无需特殊处理,注意清洁即可。
Objective To understand the bacteriological differences of parenteral nutrition solution after different treatments. Methods The prepared three-liter bags of intravenous drug preparation center were randomly divided into A, B and C 3 groups, and the iodophor disinfection screw cap was partially twice. A group with sterile gauze wrapped spiral cap part, B group with sterile towel wrapped three-liter bags, C group without special treatment. Follow the principle of aseptic operation, after preparation and infusion were completed 2 ~ 3 ml specimens for bacteriological culture, 48 hours after the observation of three groups of colonies whether there are differences.
