title: Novel ultrasound guidance system for real-time central venous cannulation: safety and efficacy.
abstract: BACKGROUND
  Real-time ultrasound guidance is considered to be the standard of care for central venous access for non-emergent central lines. However, adoption has been slow, in part because of the technical challenges and time required to become proficient. The AxoTrack(®) system (Soma Access Systems, Greenville, SC) is a novel ultrasound guidance system recently cleared for human use by the United States Food and Drug Administration (FDA).
  
  
  METHODS
  After FDA clearance, the AxoTrack(®) system was released to three hospitals in the United States. Physicians and nurse practitioners who work in the intensive care unit or emergency department and who place central venous catheters were trained to use the AxoTrack(®) system. De-identified data about central lines placed in living patients with the AxoTrack(®) system was prospectively gathered at each of the three hospitals for quality assurance purposes. After institutional review board approval, we consolidated the data for the first five months of use for retrospective review.
  
  
  RESULTS
  The AxoTrack(®) system was used by 22 different health care providers in 50 consecutive patients undergoing central venous cannulation (CVC) from September 2012 to February 2013. All patients had successful CVC with the guidance of the AxoTrack(®) system. All but one patient (98%) had successful cannulation on the first site attempted. There were no reported complications, including pneumothorax, hemothorax, arterial puncture or arterial cannulation.
  
  
  CONCLUSIONS
  The AxoTrack(®) system was a safe and effective means of CVC that was used by a variety of health care practitioners.
