Right Internal Jugular Vein (RIJV) catheterization may be collapsed by the advancement of the needle and the pressure from ultrasonic probe, and the sutures are needed to fix the catheters after RIJV catheterization. This study aimed to develop a Suture-Traction Method (STM) to facilitate RIJV catheterization. 70 anesthetized patients underwent RIJV catheterization in Left-Lateral Position (LLP). In group T, the sutures were fixed by a skin-suturing needle and adopted to fix RIJV catheters after the puncture. In group N, only after puncture a position would be selected to fix RIJV catheters by the suture. The Cross-Sectional Area (CSA) and Anteroposterior Diameter (AD) of RIJV in Supine Position (SP) and in LLP were measured. Compared to CSA and AD in SP, CSA and AD at cricoid cartilage level were smaller in LLP during cannulation in Group N. Compared to CSA and AD before cannulation, CSA and AD at cricoid cartilage level were smaller in LLP during cannulation in Group N. Compared to CSA and AD in SP, CSA and AD at cricoid cartilage level was smaller in LLP during cannulation in Group T. We found no difference in LLP before and during cannulation in Group T. Compared to patients in group N, loss of resistance, easy aspiration of blood into syringe during needle insertion, first pass punctures and cannulations completed within 60 s increased significantly while catheterization time was shortened significantly in group T. In conclusion, STM facilitates the success of RIJV catheterization in LLP in anesthetized patients.
