詳細な説明
This randomized controlled trial aims to compare the effectiveness of short-axis and long-axis ultrasound-guided approaches for cannulation of the internal jugular vein (IJV) in terms of first-pass success. Central venous catheterization is a commonly performed procedure for invasive monitoring and administration of medications and fluids. Ultrasound guidance has improved the safety and success of IJV cannulation compared with traditional landmark-based techniques; however, uncertainty remains regarding the optimal ultrasound imaging approach.
A total of 60 eligible patients undergoing IJV cannulation will be enrolled and randomly allocated into two equal groups. Participants in Group A will undergo ultrasound-guided IJV cannulation using the short-axis approach, while participants in Group B will undergo cannulation using the long-axis approach. All procedures will be performed by the researcher under direct supervision using standardized ultrasound-guided techniques.
The primary objective is to compare the frequency of first-pass success between the two approaches. First-pass success is defined as successful IJV cannulation with a single skin puncture and without needle redirection. Baseline demographic and clinical characteristics will be recorded before the procedure. The findings of this study may help identify the preferred ultrasound-guided technique for maximizing first-pass success during IJV cannulation and potentially reducing procedure-related complications associated with multiple cannulation attempts.

アクティブコンパレータ：Group A (Short-Axis Approach)
In this approach, IJV will be visualized by placing the transducer in a transverse orientation on the patient neck at the level of the cricoid cartilage.
The needle will be inserted at 60° to the vertical and will be advanced toward the vein employing gentle aspiration on the attached syringe.
Entry to the vein will be confirmed by visualizing indentation of the anterior wall of the vein followed by blood in the syringe and by visualizing the tip of the needle inside the vein.
Guide wire will be passed followed by dilator insertion and finally central vein line.

Internal jugular vein cannulation performed under ultrasound guidance using the short-axis approach.
The transducer is placed in a transverse orientation at the level of the cricoid cartilage, allowing visualization of the internal jugular vein and carotid artery during needle insertion.
|
|
アクティブコンパレータ：Group B (Long-Axis Approach)
In this approach, the probe will be centered on the IJV and rotated through 90° in a clockwise direction resulting in long axis image of the vein.
The needle insertion point will be directly beneath the most proximal end of the ultrasound probe.
The needle will be inserted at 30° to the vertical and will be advanced toward the vein employing gentle aspiration.
Entry to the vein will be confirmed by visualizing needle entry into the vein followed by aspiration of blood in the syringe.
Guide wire will be inserted followed by dilator insertion and finally central vein line.
|
Internal jugular vein cannulation performed under ultrasound guidance using the long-axis approach.
The transducer is rotated to obtain a longitudinal view of the internal jugular vein, allowing continuous visualization of the needle during vessel cannulation.
