目的:考察5种胸外科术后常用静滴液的稳定性。滴液(1)内含氯化钾、硫酸镁、辅酶A、胰岛素、三磷酸腺苷、维生素B6、维生素C等7种药物,以10%葡萄糖注射液为溶媒;滴液(2)以滴液(1)为基础加入多巴胺、多巴酚丁胺;滴液(3)、(4)、(5)以滴液(2)为基础分别加入呋塞米;肝太乐、强力宁;呋塞米、肝太乐、强力宁。方法:采用褶合光谱法结合外观和pH值检查法并以差谱值予以定量表达。结果:5种滴液8h内外观均无变化;pH值均较稳定;4h差谱值分别为0.49%,1.40%,1.79%,1.31%,1.20%。结论:滴液(3)与滴液(5)的内在药物经过8h后有较明显的变化。
Objective: To investigate the stability of five commonly used intravenous fluids after thoracic surgery. Dropping solution (1) contains 7 kinds of drugs such as potassium chloride, magnesium sulfate, coenzyme A, insulin, adenosine triphosphate, vitamin B6 and vitamin C, (3), (4), (5) to drip (2) were added to the basis of furosemide; liver too Le, tonic Ning; furosemide, Liver too happy, strong Ning. Methods: Convolutional spectroscopy combined with appearance and pH value method was used to quantify the difference. Results: The results showed that there was no change in the appearances of the five kinds of drops within 8 h, the pH values were stable, and the 4 h difference values were 0.49%, 1.40%, 1.79%, 1.31% and 1.20% respectively. CONCLUSIONS: Instillation of drops (3) and drops (5) showed significant changes after 8 hours.
