In an attempt to improve the accuracy of central venous pressure (CVP) catheter tip location, 84 consecutive cardiac surgery patients in sinus rhythm were studied prospectively with respect to subclavian insertion of a CVP catheter using a guidewire technique. The presence of cardiac arrhythmia was used as an index of right atrial (RA) location of the guidewire tip, before threading the catheter over the guidewire. Correct catheter tip location (superior vena cava [SVC] or RA) was achieved in 100% of patients (N = 78) with premature atrial contractions (PACs) related to guidewire insertion. This fell to 50% (N = 4) if no arrhythmias were noted from the guidewire. Ventricular arrhythmias were noted in two of 84 patients (2.4%). Other problems related to the use of this technique are discussed.
为提高中心静脉压(CVP)导管尖端定位的准确性,我们采用导丝技术经锁骨下静脉插入CVP导管,对84例连续的窦性心律心脏手术患者进行了前瞻性研究。在将导管沿导丝推送之前,以出现心律失常作为导丝尖端位于右心房(RA)的指标。与导丝插入相关的房性早搏(PACs)患者中,100%(n = 78)实现了导管尖端的正确定位(上腔静脉[SVC]或RA)。如果未观察到导丝引起的心律失常,这一比例降至50%(n = 4)。84例患者中有2例(2.4%)出现室性心律失常。文中还讨论了与该技术使用相关的其他问题。
