Q: What is the maximum length of guide-wire is recommended to insert (advance) during subclavian or internal jugular venous catheterization?


A: About 18 cm (may be little less in right IJ)

Beside not to loose control of guide-wire, it is appropriate to know the markings on guidewire in CVC kit. Patient height is less reliable in predicting a safe wire length. 18 cm should be considered the upper limit of guidewire introduced during central catheter placement in adults 1.
