经脐静脉导管采血对导管相关并发症的影响

Influence of blood collection through umbilical vein catheter on catheter-related complications

目的探讨从脐静脉导管采集血液标本对导管使用情况和相关并发症的影响。方法选择80例留置脐静脉导管的早产儿，随机分为采血组和非采血组各40例，比较2组患儿住院天数、导管留置时间和导管相关并发症发生率。采血组40例分别经脐静脉导管采血作为实验组、经外周血管常规穿刺采血作为对照组，比较2组采血时间、采血成功率及对患儿的影响。结果采血组和非采血组患儿住院天数、导管留置时间、导管相关并发症发生率比较无差异；实验组和采血对照组采血时间、采血成功率、采血时患儿出现不良反应比较有差异。结论脐静脉导管采血只要方法正确、操作程序规范对导管正常使用无明显影响，并具有无痛苦、成功率高、保护外周血管等优点，可作为危重新生儿采集血标本的途径之一。

Objective To investigate the effect of blood specimen collection from umbilical vein catheter on catheter usage condition and relevant complications. Methods 80 premature infants with indwelling umbilical vein catheter were divided into the blood collection group and the non-blood collection group, then the hospitalization time, catheter indwelling time and rate of catheter-related complications were compared. The 40 premature infants in the blood collection group were subsequently divided into the experimental group in which blood was collected from umbilical vein catheter and the control group in which blood was collected from peripheral blood vessel, then the blood collection time, success rate and influence on newborns were compared. Results There was no significant difference in hospitalization time, catheter indwelling time and rate of catheter-related complications between the blood collection group and the non-blood collection group. There was statistical significance in blood collection time, success rate and adverse reaction on suffering newborns between the experimental group and the control group. Conclusions There was no obvious influence on the regular service of the catheter if only the method is correct and operating procedure is normative, also it possesses advantages such as no pain, high success rate, peripheral vascular protection, etc. So, it can be used as one of the ways to collect blood speci- men for critical newborns.
