腔内3CG定位技术在肿瘤患者手臂输液港尖端定位中的应用

Application Effect of Intracavitary 3CG Localization Technique in Tip Location of Arm Infusion Port in Tumor Patients

目的探讨腔内3CG定位技术在肿瘤患者手臂输液港尖端定位中的应用效果。方法选择2021年6月25日—10月31日在郑州大学第一附属医院肿瘤科植入手臂输液港的肿瘤患者97例。按随机数字法分为观察组49例、对照组48例,观察组采用腔内3CG定位技术进行导管尖端定位,对照组采用腔内ECG定位技术进行导管尖端定位。比较2组肿瘤患者稳定心电图导出率、特征性P波出现率、原发性导管异位率、导管尖端最佳位置留置率、导管尖端定位时间。结果2组患者稳定心电图导出率、特征性P波出现率、原发性导管异位率比较差异无统计学意义(P>0.05)。观察组导管尖端最佳位置留置率(98%)高于对照组(88%)(P<0.05);观察组导管尖端定位时间(34.78±4.16)s短于对照组(49.24±6.95)s(P<0.05)。结论腔内3CG定位技术在肿瘤患者手臂输液港尖端定位中应用效果良好,有效提高导管尖端最佳位置留置率,缩短导管尖端定位时间,适宜临床借鉴应用。

Objective To investigate the application effect of intracavitary 3CG localization technique in the tip location of arm infusion port in tumor patients.Methods From June 25,2021 to October 31,2021,97 tumor patients were selected from the oncology department of the First Affiliated Hospital of Zhengzhou University.According to the random number method,the patients were divided into observation group(n=49)and control group(n=48).Catheter tip was located by intracavitary ECG and intracavitary3CG were used respectively for catheter tip in the control group and in the observation group.The stable electrocardiogram extraction rate,characteristic P wave occurrence rate,primary catheter ectopic rate,optimal catheter tip indwelling rate and catheter tip positioning time were compared between the two groups.Results There was no difference in stable electrocardiogram extraction rate,characteristic P wave occurrence rate and primary catheter ectopic rate between the two groups(P>0.05).The indwelling rate of catheter tip in the observation group(98%)was higher than that in the control group(88%)(P<0.05).The positioning time of catheter tip in the observation group 34.78±4.16 s was shorter than that in the control group 49.24±6.95 s(P<0.05).Conclusion Intracavity 3CG positioning technique is effective for the positioning of the tip of arm infusion port in tumor patients,and it improves the indwelling rate of the best position of catheter tip,shortens the positioning time of catheter tip.It is worth to be popularized in clinical practice.
