Ultrasound-guided axillary vein catheterization can be performed via the oblique-axis and long-axis approaches of the axillary vein. The aim of our study is to compare the first puncture success rate and safety between the two approaches of ultrasound-guided axillary vein catheterization in cardiac surgical patients with high bleeding risk
For patients after cardiac surgery, antiplatelet drugs or anticoagulants are usually used for preventing thrombosis. Use of those drugs is associated with increased risk of bleeding. Any invasive procedures may put those patients at additional risk of bleeding. Ultrasound (US) has become widely accepted to guide safe and accurate central venous catheterization. Ultrasound-guided axillary vein catheterization can be performed via the oblique-axis and long-axis approaches of the axillary vein. The aim of our study is to compare the first puncture success rate and safety between the two approaches of ultrasound-guided axillary vein catheterization in cardiac surgical patients with high bleeding risk
