Karakitsos and coworkers, in this journal, reported further compelling evidence on the value of ultrasound in guiding internal jugular vein catheterization. In a large, prospective, randomized study of 900 patients, comparisons were made between patients in whom the procedure was performed using landmark-based techniques and those assigned to ultrasound guidance. The key benefits from use of ultrasound included reduction in needle puncture time, increased overall success rate (100% versus 94%), reduction in carotid puncture (1% versus 11%), reduction in carotid haematoma (0.4% versus 8.4%), reduction in haemothorax (0% versus 1.7%), decreased pneumothorax (0% versus 2.4%) and reduction in catheter-related infection (10% versus 16%). The implications of these findings are discussed, and a compelling case for routine use of ultrasound to guide central venous access is made.
卡拉基索斯及其同事在本期刊上报告了关于超声引导颈内静脉置管价值的更多有力证据。在一项针对900例患者的大型前瞻性随机研究中,对采用基于体表标志技术进行该操作的患者与分配至超声引导组的患者进行了比较。使用超声的主要益处包括缩短穿刺时间、提高总体成功率(100%对94%)、减少颈动脉穿刺(1%对11%)、减少颈动脉血肿(0.4%对8.4%)、减少血胸(0%对1.7%)、降低气胸发生率(0%对2.4%)以及减少导管相关感染(10%对16%)。文中讨论了这些研究结果的意义,并提出了常规使用超声引导中心静脉通路的有力理由。
