ULTRASOUND GUIDED LONG AXIS VERSUS SHORT AXIS APPROACH FOR COMPARISON OF FIRST PASS SUCCESS RATE OF INTERNAL JUGULAR VEIN CANNULATION: A PROSPECTIVE RANDOMISED CLINICAL TRIAL

Cannulation of the internal jugular vein(IJV) is a procedure commonly performed by anaesthetists . Ultrasound, facilitates direct visualisation of the IJV, its dimensions, orientation, and surrounding structures resulting in improved first pass success rates, reduced number of needle passes and less inadvertent injury to surrounding structures . The National Institute for Clinical Excellence (NICE) published guidelines supporting the routine use of Ultrasound guidance for IJV cannulation .In addition, USG(Ultrasonography) can facilitate CVC placement in special clinical situations in which landmark techniques based on palpation of the arterial pulse are challenging or impossible. USG imaging of the IJV may be oriented along either short axis(SA) (cross sectional view) or long axis(LA) (longitudinal view)5. In this study we are comparing the first pass success rate between the two axis (short vs. long) of the Ultrasound view for cannulation of the IJV.
