POC US Procedural Benefits
May improve success and decrease complications in procedures performed by multiple specialties, including central and peripheral vascular access, thoracentesis, paracentesis, arthrocentesis, regional anesthesia, incision and drainage of abscesses, localization and removal of foreign bodies, lumbar puncture, biopsies, and other procedures. Procedural guidance may be static or dynamic. With static guidance, the structure of interest is identified, and the angle required by the needle is noted, with the point of entry marked on the skin. In dynamic procedures, ultrasonography visualizes the needle in real time. Static guidance may initially be easier to perform, but properly performed dynamic guidance provides more accurate guidance and is generally preferred by experienced users. Use of ultrasound to guide central venous access has been shown to reduce the failure rate, the risk of complications, and the number of attempts.
