一次性PVC输液管对舒血宁注射液的吸附作用研究

目的：考察一次性PVC输液管与舒血宁注射液是否存在相互吸附作用。方法：将5%葡萄糖溶液与舒血宁注射液按说明书混合,模拟临床滴注,4h内完成滴注,放出混合液,用5%葡萄糖溶液冲洗一次性PVC输液管,在6h内不同时间段收集冲洗液,用紫外分光光度法测定葡萄糖的吸光度。采用相同方法对比玻璃管的吸附作用。结果：6h内葡萄糖的吸光度间RSD均〈3%,一次性PVC输液管与舒血宁注射液间无吸附作用;玻璃管的吸附作用与一次性PVC输液管比较无显著性差异。结论：一次性PVC输液管对舒血宁注射剂无明显吸附作用。

Adsorption Effect of Disposable Tansfusion Tube on Shuxuening Injection

OBJECTIVE： To investigate whether there was adsorption reaction between disposable PVC transfusion tube and Shuxuening injection or note. METHODS： According to package inserts, 5% Glucose solution mixed with Shuxuening injection to complete clinical dripping within 4 h and then was pour away. Disposable PVC transfusion was flushed with 5% Glucose solution, and flushing fluid was collected at different periods within 6 h. The absorbance of glucose was determined by UV spectrophotometer. Same method was adopted for the determination of adsorption effect of glass tube. RESULTS： The RSD of glucose was less than 3% within 6 h, and there was no adsorption reaction between disposable transfusion tube and Shuxuening injection; there was no significant difference in adsorption effect between glass tube and disposable transfusion tube. CONCLUSION：Disposable transfusion tube has no apparent adsorption effect on Shuxuening injection.
