A Descriptive Comparison of Ultrasound Guided Central Venous Cannulation of the Internal Jugular to Landmark Based Subclavian Vein Cannulation

摘要

The safest site for central venous cannulation (CVC) remains debated. Many emergency medicine physicians advocate the ultrasound guided internal jugular approach (USIJ) because of data supporting its efficiency. However, a number of physicians prefer, and are most comfortable with, the subclavian vein approach. The purpose of this study was to describe adverse event rates among operators using the USIJ approach and the landmark subclavian vein approach without ultrasound (SC).MethodsThis was a prospective observational trial of patients undergoing CVC of the subclavian or internal jugular veins in the Emergency Department (ED). Physicians performing the procedures did not undergo standardized training in either technique. The primary outcome was a composite of adverse events defined as hematoma, arterial cannulation, pneumothorax, and failure to cannulate. Physicians recorded the anatomical site of cannulation, ultrasound assistance, indications and acute complications. Variables of interest were collected from the pharmacy and ED record. Physician experience was based on a self-reported survey. We followed outcomes of central line insertion until device removal or patient discharge.
