Pneumatic tube systems (PTSs) are widely used in many hospitals because they lead to reduced turnaround times and cost efficiency. However, PTSs may affect the quality of the blood samples transported to the laboratory. The aim of this study was to investigate the effect of the PTS used in our hospital on the hemolysis of the biochemical blood samples transported to the laboratory.
A total of 148 samples were manually transported to the laboratory by hospital staff, 148 samples were transported with the PTS, and 113 were transported with the PTS without use of sponge-rubber inserts (PTSws). Hemolysis rates and the levels of biochemical analytes for the different transportation methods were compared.
No significant difference was found between the samples transported manually and with the PTS with regard to hemolysis rate and the levels of biochemical analytes. However, the samples transported with the PTSws showed a significant difference compared with the samples transported manually and with the PTS with regard to hemolysis rate and potassium and lactate dehydrogenase levels. The percentages of the samples that exceeded the permissible threshold for the hemolysis among the samples transported manually, with the PTS, and with the PTSws were 10%, 8%, and 47%, respectively.
A PTS can be used safely for transporting biochemistry blood samples to the laboratory. However, a sponge-rubber insert that holds sample tubes must be used with the PTS to prevent the hemolysis of blood samples.
气动管道系统（PTSs）在许多医院广泛使用，因为它们能缩短周转时间并提高成本效益。然而，PTSs可能会影响运送至实验室的血样质量。本研究的目的是调查我院使用的PTS对运送至实验室的生化血样溶血的影响。
医院工作人员将148份样本手动运送至实验室，148份样本通过PTS运送，113份样本通过未使用海绵橡胶插入物的PTS（PTSws）运送。比较不同运送方式的溶血率和生化分析物水平。
手动运送和通过PTS运送的样本在溶血率和生化分析物水平方面未发现显著差异。然而，与手动运送和通过PTS运送的样本相比，通过PTSws运送的样本在溶血率、钾和乳酸脱氢酶水平方面存在显著差异。手动运送、通过PTS运送和通过PTSws运送的样本中超过溶血允许阈值的样本百分比分别为10%、8%和47%。
PTS可安全用于将生化血样运送至实验室。然而，PTS必须搭配用于固定样本管的海绵橡胶插入物使用，以防止血样溶血。
