Recent advances in ultrasound technology have made ultrasound equipment more
versatile, portable, and accessible than ever. Modern handheld, ultra-portable
ultrasound devices have been developed by multiple companies and are contributing
to make bedside ultrasound evaluation a practice available to all physicians. The
significance of making point-of-care ultrasound (POCUS) a common practice that
all physicians eventually can use in the evaluation of their patients is changing
the way medicine is practiced, allowing physicians to quickly obtain valuable
information to complement the traditional physical examination. Despite the
proven benefits of using bedside ultrasound imaging as a part of the patient
evaluation and for procedure guidance, adoption of this technology still is not
widespread among anesthesiology clinicians nor is there uniform teaching of
ultrasound skills to anesthesia residents and faculty. Among obstacles that have
been identified as precluding achievement of the goal of widespread utilization
of POCUS among anesthesia professionals and trainees, are the availability of
equipment for all physicians when it is needed and lack of instructor supervision
for trainees who desire to use ultrasound but do not always have an instructor
knowledgeable in POCUS with them when an ultrasound examination is warranted.
Herein, the characteristics, advantages, and limitations of available
ultra-portable, handheld ultrasound devices are analyzed, with a focus on the
Butterfly iQ (Butterfly Network, Inc, Guilford, CT) pocket probe, which is
available at the authors' institution, and how some of its features, such as the
capacity to emulate multiple transducers and its cloud-sharing and teleguidance
technology, may contribute to increase the availability and use of POCUS by
anesthesia clinicians.
