Peripherally inserted central catheter placement using the Sonic Flashlight.

Area of Science:

• Medical Devices
• Ultrasound Imaging
• Interventional Radiology

Background:

• Ultrasound (US) is crucial for guiding medical procedures.
• Real-time US imaging enhances procedural accuracy and safety.
• Existing methods for integrating US devices into sterile fields can be cumbersome.

Purpose of the Study:

• To evaluate the feasibility of the Sonic Flashlight for clinical peripherally inserted central catheter (PICC) placements.
• To assess a novel sterile design for the Sonic Flashlight's mirror component.
• To determine if the new design maintains or improves image visibility while ensuring sterility.

Main Methods:

• The Sonic Flashlight, an ultrasound device projecting real-time images via a mirror, was used for PICC line insertions.
• Two configurations were tested: mirror inside a sterile cover (n=15) and mirror outside (n=11).
• Feasibility was assessed by successful vascular access and subjective/photographic evaluation of image visibility and sterility.

Main Results:

• All procedures achieved successful vascular access.
• The revised sterile design (mirror outside) subjectively and photographically demonstrated improved image visibility.
• The new design effectively maintained sterility without compromising visualization.

Conclusions:

• The Sonic Flashlight is a feasible tool for ultrasound-guided PICC line insertions.
• The updated sterile design enhances visibility and maintains sterility.
• Further clinical trials with healthcare professionals are warranted to validate these findings.
