Effects of four different positive airway pressures on right internal jugular vein catheterisation.
The right internal jugular vein (RIJV) is often used for central venous catheterisation in patients undergoing major surgery. The efficacy of this route correlates with the diameter of the vein which can be influenced by airway pressure. ⋯ A PAP of 20 cmH2O seems most suitable for successful RIJV catheterisation in mechanically ventilated patients. It is associated with an increase in cross-sectional RIJV area and CVP, which facilitate cannulation, and results in fewer puncture-related complications. However, meticulous haemodynamic monitoring is needed to avoid hypotension and bradycardia.
