When right atrial catheters are used to diagnose and treat venous air emboli in sitting neurosurgical patients, it is possible to position the catheter tip near the junction of the superior vena cava and right atrium using electrocardiogram (ECG)-based methodologies. This report describes three patients in whom this technique could not be accomplished when using the Arrow Antecubital Central Venous Catheterization Kit (Product #AK04250). The problem resulted from an imperfection in the kit's catheter-to-ECG adapter which, in turn, produced an electrical resistance that was 2.5 times greater than normal. Replacement of the adapters with the Arrow-Johans ECG Adapter (Product #EG04900) reduced the electrical resistance and permitted positioning of the catheter using the ECG.
当使用右心房导管来诊断和治疗坐位神经外科手术患者的静脉空气栓塞时，采用基于心电图（ECG）的方法能够将导管尖端放置在上腔静脉与右心房的交界处附近。本报告描述了3例患者，在使用Arrow肘前中心静脉置管套件（产品编号AK04250）时无法完成该技术操作。问题源于该套件的导管与心电图适配器存在缺陷，进而产生了比正常情况大2.5倍的电阻。将适配器更换为Arrow-Johans心电图适配器（产品编号EG04900）后降低了电阻，并允许使用心电图来定位导管。
