正交试验法优选注射用硝普钠与输液配伍方案

Optimization of Compatibility Plan for Sodium Nitroprusside and Infusions by Orthogonal Design

目的:研究注射用硝普钠输液的最佳配伍方案。方法:选择温度、溶媒、溶媒用量、时间4个影响因素,采用L16(43×26)因素水平表,用高效液相色谱法对各样品溶液中的硝普钠含量进行了测定,用GWF-5J型微粒分析仪对各样品溶液中的微粒含量进行了测定,用pHS-2C型精密酸度计对各样品溶液中的pH进行了测定,并结合综合评分对注射用硝普钠输液的最佳配伍方案进行了优选研究。结果:最佳配伍方案为硝普钠50 mg,溶于250 ml 0.9%氯化钠注射液中,避光下,在26 h内输液质量稳定。结论:该输液配伍方案为临床用药提供了科学依据。

Objective：To investigate the best compatibility plan for nitroprusside sodium for injection. Methods： An L16 （43 × 26 ） orthogonal design was used with four factors：temperature, solvent, solvent volume and time. The content of sodium nitroprusside was detected by HPLC, the insoluble particles were observed by a GWF-5J type particle analyzer, pH was detected by a PHS-2C preci-sion acidity meter, and a comprehensive scoring method was used to optimize the compatibility plan. Results：The optimized compati-bility plan was as follows：50mg sodium nitroprusside was dissolved in 250ml sodium chloride injections, avoiding light and used up in 26h. Conclusion：The plan provides scientific basis for the clinical medication.
