摘要目的 分析经深静脉导管采集血标本在危重患者中的应用效果.方法 收集分析2014年4月至2016年6月我院收治的危重患者40例,进行不同部位采血,分别为浅静脉采血和对侧肢体深静脉采血,比较两种采血方式的血常规、血生化、并发症发生率情况.结果 对侧肢体深静脉采血组血常规RBC、WBC、Hb、PLT与浅静脉采血组比较,差异无统计学意义(P>0.05).对侧肢体深静脉采血组血生化血钾、血钠、血氯、血钙、尿素氮、二氧化碳结合力与浅静脉采血组比较,差异无统计学意义(P>0.05).对侧肢体深静脉采血组并发症发生率10%明显低于浅静脉采血组的32.5%,差异有统计学意义(P<0.05).结论 经深静脉导管采集血标本能够解决经外周反复穿刺,损伤血管及周围组织的问题,减少并发症发生,操作简单、职业暴露小,提高了静脉采血的安全性,具有良好的临床应用价值.

abstractsObjective To analyze the application of blood samples collected through deep cervical venous catheter to the care of critically ill patients. Methods A total of 40 cases of critically ill patients in our hospital from April 2014 to June 2016 were collected and analyzed. Blood was drawn from different parts, namely shallow venous blood and the contralateral limb deep vein blood. The blood routine, blood biochemistry and the incidence of disease complications of the two ways were compared. Results The differences in terms of the RBC, WBC, Hb and PLT of the contralateral limb deep vein blood group and the superficialx venous blood group were not statistically significant ( P>0. 05). The differences in terms of the blood biochemical, sodium, serum chloride, calcium, blood urea nitrogen and carbon dioxide binding force of the contralateral limb deep vein blood group and the superficial vein group were not sta-tistically significant ( P>0. 05 ) . The rate of complications of the contralateral limb deep vein blood group was 10%, which was significantly lower than that of superficial venous blood group 32. 5%, and the difference was statistically sig-nificant ( P<0. 05 ) . Conclusions Blood samples collected through deep cervical venous catheter can solve such prob-lems, for example, peripherally repeated puncture, damaged blood vessels and surrounding tissue, meanwhile it can reduce complications with simple operation and less occupational exposure, and can improve the venous blood safety as well, which has good clinical value.
