输液是临床治疗中的重要方法之一,输液中的不溶性微粒(insolubleparticles,IP)对人体造成的危害很大,文献报导中药注射剂输液配伍后引起微粒增加,影响输液质量,为此我们考查了三种中药注射剂输液配伍前后的微粒变化情况,以及通过一次性输液器后的微粒情况,从而客观地反映临床应用中微粒的变化. Infusion is one of the important methods in clinical treatment. The insoluble particles (IP) in the infusion are harmful to the human body. The literature reports that the infusion of traditional Chinese medicine injections will increase the particulates and affect the quality of infusion. For this reason, we have examined three. The variations of the microparticles before and after compatibility of the TCM injection infusion and the condition of the microparticles after passing through the disposable infusion set objectively reflect the changes of the microparticles in the clinical application.
