Purpose: The subclavian vein is thought to be the most appropriate route for central venous access in major maxillofacial surgery. Evidence suggests that left-sided central venous catheters should lie below the carina and be angulated at less than 40 degrees to superior vena cava wall. This reduces perforation risk. With ...

BACKGROUND: The internal jugular vein (IJV) is one of the recommended sites for safe insertion of a central venous catheter (CVC). Although CVC insertion via the IJV has a lower risk of severe complications such as pneumothorax and arterial bleeding than insertion via the subclavian vein, few reports have provided ...

Central venous catheterisation and arterial catheterisation are common procedures performed by anaesthetists. Traditionally, the technique of locating surface landmarks and palpation was used to assist in vascular access. The introduction of perioperative ultrasonography in the past decade has dramatically changed this procedure. In the United States and United Kingdom, guidelines ...

OBJECTIVE: Accidental arterial cannulation during ultrasound-guided central venous cannulation is rarely reported and should be much less likely with dynamic guidance. Although accidental arterial penetration with the needle may occur periodically without notice and with little harm, actual arterial dilation and line placement may result in serious complications. METHODS: This ...
