为了进一步提高大输液质量,保证用药安全,下面就其澄明度的提高、检查及临床意义,结合部分国内外文献作一综述。大输液澄明度的提高注射液的澄明度从字面上讲就是注射液澄清透明的程度,它与溶液所含异物的数量有直接关系:异物多则澄明度差;异物少则澄明度好。由于大输液多由静脉直接注入血流,而在制备、贮存和使用过程中又常会带来异物,因此如何提高大输液的澄明度应引起我们的注意。大输液中的异物多种多样,主要包括有;白点(来自滤器或容器),色点(来自橡皮屑或灰尘),闪光点(来自玻璃屑或衬垫薄膜),纤维(来自衣帽、头发和空气)和其它物质(来自霉菌甚至小昆虫)。通过对异物的识别,也可发现在制备、贮存和使用过程 In order to further improve the quality of large infusion, to ensure drug safety, the following to improve its clarity, examination and clinical significance, combined with some domestic and foreign literature to make a review. The clarity of large infusion clarity Injection literally is the clarity and clarity of the injection, which is directly related to the amount of foreign material contained in the solution: foreign matter is often poorly defined; foreign matter is less clear. As large transfusion directly into the bloodstream by the veins, and in the process of preparation, storage and use often bring foreign body, so how to improve the clarity of large infusion should be our attention. Foreign bodies in large transfusions are diverse and include predominantly white spots (from filters or containers), color spots (from chaff or dust), flash points (from glass crumbs or liner films), fibers (from garments, Hair and air) and other substances (from mold or even small insects). Through the identification of foreign objects can also be found in the preparation, storage and use of the process
