Central venous access is necessary in a multitude of clinical situations, including vascular access, vasopressor and caustic medication delivery, central venous pressure monitoring, intravascular device delivery (pacing wires, Swann-Ganz catheters), volume resuscitation, total parental nutrition, hemodialysis, and frequent phlebotomy.

Central venous access is necessary in a multitude of clinical situations for hemodynamic monitoring, medication delivery, and blood sampling. There are three veins in the body that are accessed for central venous cannulation: the internal jugular, the subclavian, and the femoral vein.
Central venous access via the subclavian vein has several advantages over other possible locations. The subclavian...

The overall goal is to enable clinicians to insert a central venous catheter under real-time ultrasound guidance via the right supraclavicular fossa view of the lower part of the superior vena cava. This view is useful for different catheter insertion sites, thrombosis detection before insertion and ultrasound guided correction of misplaced...

We present a protocol to show the installation of a needle-free connector with positive displacement on a central venous...

This protocol provides a detailed description of inducing cerebral air emboli in rats. It compares direct injection into the common carotid artery and introduction through the external carotid artery. It provides a technical description of the air bubble generator, the effect of different air volumes, and procedural...
