  1. THE FEASIBILITY OF A NOVEL ULTRASOUND GUIDED VASCULAR ACCESS DEVICE: A PILOT STUDY Robinson M Ferre, MD, FACEP Vanderbilt University Medical Center Robinson.Ferre@vanderbilt.edu Shannon B Snyder, MD, FACEP Vanderbilt University Medical Center Shannon.Snyder@Vanderbilt.edu Matthew Lipton, MD University of Utah Medical Center Matthew.Lipton@Utah.edu

  2. Background • US Guided Central Venous Line (CVL) insertion is endorsed by many professional organizations • Many obstacles exist for widespread implementation • Learning US guided CVL insertion can be challenging for physicians • Complications reduced with US guided CVL insertion, but still occur

  3. Methods • Observational Study of adult patients in ED or ICU receiving CVL with AxoTrack™ System • IRB Approved • Convenience sample • Data collected by independent observer with video recordings of CVL insertion • Primary Outcome: First Pass Success • Secondary Outcomes: • Complications (Arterial puncture, arterial cannulation, pneumothorax, hemothorax, hematoma, catheter malposition) • Successful Procedure • Number of attempts • Physician satisfaction

  4. AxoTrack System Needle hub: Magnetic ceramic hub needed for Hall Effect sensor Holographic image of the needle Hole in probe: Needle passes through a hole in the probe to maintain needle along trajectory line Magnetic Post: Uses Hall Effect technology to display location of the needle on the screen at all times Transducer: Phased array Needle Trajectory Line

  5. Results • 30 Patients • Mean Age: 54 yo • Sex (Female): 47% • Hospital Location: • 70% Emergency Department • 30% ICU

  6. Results Internal Jugular = 9 (30%) Subclavian: Infraclavicular = 4 (13%) Supraclavicular =17 (57%)

  7. Results • Primary Outcome: • First Pass Success = 26/30 (87%) • Secondary Outcomes: • Complications = 0 • Successful Procedure = 29/30 (97%) • 1 failure was with infraclavicular subclavian approach • Mean number of attempts = 1.1

  8. Results • Physician Satisfaction: • 25 (80%) rated the AxoTrack system very or relatively easy to use during the procedure • 25 (86%) preferred AxoTrack System overall compared with the traditional US guidance • 30 (100%) preferred AxoTrack Systems ability to guide the needle into the vein compared with the traditional technique

  9. Conclusion The AxoTrack system is a safe and effective means of performing central venous access in critically ill patients.
