Technique of ultrasound-guided peripheral venous access in the emergency room

Abstract

In emergency situations, patients may need a fast and reliable peripheral venous access, which sometimes may be difficult to obtain, because of poor visualization of the superficial veins due to edema, obesity, hypovolemia or local abnormalities. In such cases, insertion of a central line is potentially time consuming and possibly associated with complications. Furthermore, central lines inserted in emergency are known to be at high risk of infection, so guidelines recommend that they should removed within 24 to 48 hours. In this setting, ultrasound-guided placement of a peripheral venous access might be more rapid, safer and more cost-effective than a central line.
