Critical skills and procedures in emergency medicine: vascular access skills and procedures.

The venous and/or arterial vasculature may be accessed for fluid resuscitation, testing and monitoring, administration of blood product or medication, or procedural reasons, such as the implantation of cardiac pacemaker wires. Accessing the vascular system is a common and often critically important step in emergency patient care. This article reviews methods for peripheral, central venous, and arterial access and discusses adjunct skills for vascular access such as the use of ultrasound guidance, and other forms of vascular access such as intraosseus and umbilical cannulation, and peripheral venous cut-down.
