Ultrasound US guidance is also able to decrease the time required to cannulate the vessel. A meta analysis of ultrasound guided central venous access in adults concluded that for internal jugular procedures ultrasound guidance was significantly more successful than the landmark technique alone. With the recent focus on patient safety and clinical outcomes the American College of Emergency Physicians published a policy statement included in the guidelines use of US guidance for central venous access in a list of primary applications for ultrasound in the emergency department.
