Conditions

Comparison of the coventional 15 centimeter method with the carinal distance C-Length method for central venous catheter placement in patients candidate for elective coronary artery by-pass graft operation under by-pass pump.

Interventions

Intervention 1: In the 15 cm group the point of number 15 centimeter on the catheter will be the fixation site at the cutaneous insertion point. The central venous catheters will be placed by one defi

In the 15 cm group the point of number 15 centimeter on the catheter will be the fixation site at the cutaneous insertion point. The central venous catheters will be placed by one defined anesthesiolo

In the C-Length group the point at which the catheter will be fixed at the cutaneous insertion point will be according to a predefined distance between the carina bifurcation and the right tip of the
