影响大输液澄明度变化的因素很多,根据我们所作的一些调查,其主要原因是:(1)输液在贮存期间澄明度发生了变化;(2)包装材料洗涤不干净;(3)输液加药时操作不正规等。临床输液澄明度在很多环节上都可以出现问题,我们设想利用二、三号两种垂熔滤球作为补液装置中的过滤器(见附图),使输液中微粒在进入血管时减少到最低限度,以避免输液 There are many factors that affect the clarity of large transfusion. According to some of our surveys, the main reasons are: (1) the clarity of transfusion during storage changes; (2) the packaging material is not cleanly washed; (3) When the operation is not formal and so on. Clinical transfusion clarity can be problematic in many areas, and we envisaged using two or more of the three drop-in filters as filters in the fluid replacement device (see the accompanying figure) to minimize the amount of particulates in the transfusion when entering the blood vessel Limit to avoid transfusion
