不同处方全肠外营养液的稳定性考察
发布时间:2018-10-11 09:19
【摘要】:目的:考察临床常用全肠外营养液(TPN)中的不溶性微粒数及其配伍稳定性,为临床应用提供参考。方法:选择临床常用的6种TPN处方,按无菌操作规程配制后,在室温(25℃)下,分别考察其在0、1、4、8、24 h各时间点的外观、pH值、渗透压和不溶性微粒数。结果:配制后24 h内,各TPN的外观及pH值未见明显变化,渗透压均900 m Osm/L。对其不溶性微粒数的考察结果显示,加入注射用脂溶性维生素后,TPN中的不溶性微粒数急剧增加,≥10μm和≥25μm的微粒数均超出药典规定范围;中/长链脂肪乳注射液、水溶性维生素、混合糖电解质和微量元素的加入,也使其不溶性微粒数增加。结论:中/长链脂肪乳注射液、脂溶性/水溶性维生素、维生素C、混合糖电解质和微量元素对TPN的不溶性微粒数均有一定的影响。
