UNASSIGNED: This study retrospectively enrolled 80 adult patients who received central venous port (CVP) implantation via the IJV from April 1, 2022, to November 10, 2023, in our institution. Traditional needle-and-catheter was used for ultrasound (US)-guided IJV puncture (usual group) for the former 40 patients before July 18, 2023. Afterward, the 3D needle was used for the latter 40 patients (3D needle group). US images were stored and analyzed to calculate the deformation rate.
UNASSIGNED: The deformation rate was 58.6% (13.2-100) for the usual needle and 41.8% (10.6-100) for the 3D needle (p = 0.0034). Patients who required several punctures included 2 for the usual needle and 12 for the 3D needle, respectively (p = 0.0032). All patients and the usual needle group demonstrated a weak negative correlation between the deformation rate and pre-puncture vessel diameter (r = 0.24 and 0.41, respectively), with no correlation in the 3D needle group.
UNASSIGNED: The deformation rate of the IJV wall was smaller in the 3D needle group than in the usual needle group. The use of a 3D needle would be safer when puncturing the IJV.
■这项研究回顾性地纳入了我们机构的80名成年患者,这些患者于2022年4月1日至2023年11月10日通过IJV接受了中央静脉端口(CVP)植入。在2023年7月18日之前,前40名患者使用传统的针和导管进行超声(US)引导的IJV穿刺(常规组)。之后,后40例患者使用3D针(3D针组).存储并分析US图像以计算变形率。
■通常的针的变形率为58.6%(13.2-100),3D针的变形率为41.8%(10.6-100)(p=0.0034)。需要多次穿刺的患者包括2个普通针头和12个3D针头,分别(p=0.0032)。所有患者和常规针组的变形率与穿刺前血管直径之间呈弱负相关(r分别为0.24和0.41)。在3D针组中没有相关性。
■3D针组的IJV壁的变形率小于通常的针组。在穿刺IJV时,使用3D针会更安全。
