摘　　要：目的:探讨腔内心电定位技术辅助患者中心血管通路导管尖端定位中的应用效果。方法:选取2023年6月至2024年6月在我院行中心血管通路置管的患者100例,通过便利抽样方法,选取肿瘤血液科住院患者为观察组,其他病区住院患者为对照组,两组患者各50例。两组患者均在B超引导下置管,置管术后均行X线胸片定位以验证导管尖端位置。对照组患者中心血管通路(Central Vascular Access Devices, CVAD)置管采取传统的体表预测量长度和超声定位,观察组患者CVAD置管在传统的体表预测量长度结合超声定位的基础上增加了腔内心电定位技术定位。比较两组患者置入后导管尖端位置的准确率。结果:观察组导管尖端准确率100%明显高于对照组82% (P 2 = 11.657, P The aim was to explore the effectiveness of intracavitary electropositioning technology in assisting catheter tip positioning for cardiovascular access in patients. One hundred patients who underwent central vascular access catheterisation in our hospital from June 2023 to June 2024 were selected. By facilitating the sampling method, Patients hospitalised in the oncology and hematology department were selected as the observation group and patients hospitalised in other wards as the control group, 50 patients in each of the two groups. Patients in both groups were placed under ultrasound guidance, post-catheterisation X-ray chest radiographs were performed to locate and verify the catheter tip position. In the control patients (Central Vascular Access Devices, CVAD) tube placement was done by the traditional body surface premeasurement length method and ultrasound positioning, CVAD placement in patients in the observation group was localised with the addition of the intracavitary electro-positioning technique to the traditional body surface premeasurement length method and ultrasound localisation. To compare the accuracy of catheter tip placement between the two groups of patients. The results show
