3. Accurate ultrasound
The goal of most modern ultrasound machines is enhanced imaging
with an easy-to-use interface. The latest options are more user-friend-
ly and feature designs such as tablet-based models for increased
portability and intuitive touchscreens.
One item to look at while shopping for devices is the ultrasound
probe itself. The updated options now include hot buttons on the
handpiece that let the user save, print or freeze an image instantly
with the push of a button. It's a small thing, but it prevents the
provider from having to stop what he's doing and manipulate the
screen during placement. That can be a big timesaver, especially if
you have limited staff and the clinician placing the block is also con-
trolling the ultrasound.
Enhanced visualization is also a key feature. New models may offer
needle visualization technology that let the user more easily see the
needle, even when working at a steep angle. There are also "high-defi-
nition" ultrasound machines available, which provide a better quality
image, so even beginner practitioners can place blocks.
While these advancements are certainly helpful, there is a huge
growth expected in this area in the future. Soon-to-market products
include machines that use magnetics or GPS to determine precisely
where the needle is located during a block placement. Magnetic ultra-
sound probes will be able to sense the needle tip and use algorithms to
show the provider an exact location on screen, even if the needle isn't
perfectly in plane. GPS models may take it a step further and use small
GPS sensors to track a particular needle during insertion. These sorts
of advances would help less-skilled practitioners enhance the efficacy
and safety of their blocks.
