目的:考察生脉注射液用5种输液调配后成品输液的稳定性。方法:室温(25℃)条件下,观察5种成品输液的性状、检测pH,不溶性微粒数及五味子醇甲的含量变化。结果:用乳酸钠林格注射液(SLR)调配的输液,不溶性微粒不符合规定。其余4种输液符合规定;含量测定在8h内无明显变化,显示稳定性良好。结论:生脉注射液不宜用SLR调配,建议临床使用时用5%GS、10%GS、0.9%NS或GNS调配,且在4h内使用。
Objective: To investigate the stability of infusion solution of Shengmai injection with 5 kinds of infusions. Methods: Under the condition of room temperature (25 ℃), the properties of five kinds of finished infusion products were observed. The changes of pH, insoluble particles and schisandrin content were observed. RESULTS: Infusion solutions formulated with sodium lactate Ringer’s injection (SLR) did not meet the specifications. The remaining 4 kinds of infusion meet the provisions; content determination within 8h no significant change, showing good stability. Conclusion: Shengmai injection should not be used SLR deployment, it is recommended when clinical use of 5% GS, 10% GS, 0.9% NS or GNS deployment, and within 4h.
