不同静脉留置针部位采血在生长激素激发试验中的可行性研究

Feasibility of blood collection from different intravenous indwelling needle sites in growth hormone stimulation test

目的探讨不同静脉留置针部位采血在生长激素激发试验中的可行性,为矮小症患儿行生长激素激发试验时采血部位的选择提供参考。方法选取2022年10月-2023年3月在某三级甲等医院儿童生长发育门诊就诊,需行生长激素激发试验的144例矮小症患儿为研究对象,采用简单摸球法随机分为观察组和对照组,比较两组一次性穿刺成功率、堵管发生率及渗血、血肿并发症发生情况。结果观察组78例,一次性穿刺成功率92.4%、堵管率6.41%、并发症发生率3.8%;对照组66例,一次性穿刺成功率92.3%、堵管发生率3.03%、并发症发生率25.7%。两组的一次穿刺成功率和堵管率差异均无统计学意义(P>0.05),穿刺后观察组的渗血、血肿的发生率低于对照组(P<0.05)。结论生长激素激发试验采用贵要静脉留置针采血与肘正中静脉留置针采血穿刺成功率相当,且贵要静脉留置针采血并发症少,能为临床提供借鉴。

Objective To explore the feasibility of blood collection at different places of intravenous indwelling needle in growth hormone stimulation test,providing reference for blood collection site in children with dwarfism.Methods A total of 144 children with dwarfism who were treated in the children's growth and development clinic of our hospital from October 2022 to March 2023 and required growth hormone stimulation test were selected.Children meeting the inclusion criteria were randomly divided into two groups by touch ball method.The observation group included 78 cases,and the control group 66 cases.The success rate of one-time puncture,the incidence of tube blockage and the occurrence of hematoma complications were compared between the two groups.Results In observation group,the one-time puncture success rate was 92.4%,the tube blockage rate was 6.41%,and the complication rate was 3.8%.In the control group,the success rate of one-time puncture was 92.3%,the incidence of tube blockage was 3.03%,and the incidence of complications was 25.7%.There was no difference in the success rate of puncture and the rate of tube blockage between the two groups(P>0.05).The incidence of bleeding and hematoma in the observation group was lower than those in the control group(P<0.05).Conclusion The success rate of blood collection with basilic vein indwelling needle in growth hormone stimulation test is similar to that of median cubital vein indwelling needle,yet with less complications of blood collection,which can provide reference for clinic.
