Utrasound guided internal jugular venous canulation by three different transducer orientation( short axis, long axis, oblique axis): A Randomized comparative study.

Internal jugular vein (IJV) is the commonest vein for central venous cannulation.It is commonly performed in operating room and critical care settings.Maximum number of times it is performed by less experienced operator.The curent evidence based recommend the use of ultrasound whenever possible.Different imaging approaches have been described. The short axis view approach,the long axis view approach, the oblique axis view approach.At majority of centres short axis view is most commonly approached view.This study was designed to assess and compare the performance of these three approaches in terms of cannulation successs and incidence of complication.
