Evaluating the Long‐, Short‐, and Oblique‐Axis Approaches for Ultrasound‐Guided Vascular Access Cannulation

Abstract

There was insufficient evidence to definitively recommend the LAX, SAX, or OAX approach for patients undergoing ultrasound-guided vascular access cannulation.

Is ultrasound guided syringe-free method more efficient for saphenous vein catheterization? A prospective randomized controlled study

“…Ultrasound-guided vein intervention methods have been compared and studied multiple times in the past [9,10]. There are studies that determined that long axis, short axis, and oblique axis approaches while applying an ultrasound-guided internal jugular venous catheterization don't provide different results within the context of success [11]. Even though it is reported that the primary intervention process takes a shorter period in short axis out of plane approach when compared to the long axis, this difference is not determined as significant [12].…”

How to Measure Outcome—The Art of Evaluating Success

“…There are numerous studies and reviews published describing and comparing the various US and traditional landmark techniques. [6][7][8][9][10][11] Shortcomings of the various techniques are discussed, and alternatives and alterations presented. [12][13][14][15] With few exceptions, USguided IJV access has been associated with a higher success rate on first attempt, fewer failed attempts, and higher success rate overall, and frequently was associated with fewer complications.…”

Does longitudinal or transverse orientation of the ultrasound probe improve cannulation success in minimally invasive venous surgery: A multicentre randomised controlled trial

“…While the benefit of ultrasound-guided cannulation is well established 7,8 studies assessing the effect of its orientation on cannulation of the larger calibre internal jugular vein (IJV) are inconsistent. [9][10][11] This heterogeneity limits generalisability to the smaller, less accessible lower limb venous trunks. At present, despite its widespread application, there is a paucity of evidence to guide ultrasound orientation during access for lower limb endovenous ablation.…”
