ABSTRACT
OBJECTIVE:To investigate the stability of blood preservation solutionⅠin polyvinyl chloride(PVC)plastic bag in the valid period.METHODS:3batches of samples were divided into2groups,in group one,each sample was covered with outer packaging bag of polypropylene laminated film,and samples in group two were covered with no outer packaging bag,both groups were stored at room temperature,and stability test was conducted by observing samples.RESULTS:(2.95?0.05)%was the samples,content without outer packaging bag after they had been stored for2years,while less than0.5%water was lost in the samples covered during the same period.CONCLUSION:It is proper to add outer packaging bag of polypropylene laminated film to blood preservation solutionⅠin PVC plastic bag.
