胸片定位法在肺癌患者经外周静脉行中心静脉置管中的应用研究

目的探讨胸片定位法在肺癌患者经外周静脉行中心静脉置管(PICC)中的应用效果,为提升置管成功率提供依据。方法选取2016年7月-2018年6月在西安交通大学第一附属医院肿瘤病房住院需要PICC置管进行化疗的肺癌患者300例,采取非同期对照法分为观察组和对照组各150例,观察组采取胸片定位法得出PICC置管长度,对照组采取体表测量公式计算PICC置管长度,比较两组置管成功率、置管长度调整率、患者满意度及置管并发症的发生率。结果观察组置管长度调整率为零,对照组为4.67%,差异有统计学意义(P<0.05);观察组置管成功率为99.33%,对照组为94.00%,差异有统计学意义(P<0.05);观察组并发症发生率为0.67%,对照组为5.33%,差异有统计学意义(P<0.05);观察组患者满意率为96.67%,对照组为90.67%,差异有统计学意义(P<0.05)。结论胸片定位法能提升肺癌患者PICC置管成功率,降低置管长度调整率,减少置管并发症的发生率,提升患者满意率,值得临床推广应用。

Study of the effectiveness on applying sternography in locating the tip of peripherally insterted center catheter for lung cancer patients

Objective To study the effectiveness on applying sternography in locating the tip of peripherally insterted center catheter(PICC)for Lung cancer patients,to provide evidence for improving the success rate of PICC.Method 300 patients with lung cancer who needed PICC catheterization for chemotherapy in the oncology ward of the First Affiliated Hospital of Xi’an Jiaotong University from July 2016 to June 2018 were selected and divided into the observation group and the control group by non-synchronous control method,150 patients respectively in each group.In the observation group,the length of PICC catheter was obtained by sternography,while in the control group,the length of PICC catheter was calculated by body surface measurement formula.The success rate,the length adjustment rate,the patient satisfaction and the complications of PICC catheterization were measured and compared between the two groups.Results The adjustment rate of catheter length was zero in the observation group,It was 4.67%in the control group,the difference was statistically significant(P<0.05);The success rate of catheterization was 99.33%in the observation group,It’s was 94.00%in the control group.The difference was statistically significant(P<0.05);The incidence of complications was 0.67%in the observation group,It was 5.33%in the control group.The difference was statistically significant(P<0.05);The satisfaction rate of patients in the observation group was 96.67%,It’s was 90.67%in the control group.The difference was statistically significant(P<0.05).Conclusion Sternography can improve the success rate of PICC catheterization in lung cancer patients,and reduce the adjustment rate of catheter length,decrease the incidence of catheterization complications,and reflect patients’ satisfication.It is worthy of clinical application.
