A Study to Test Performance of Needle Placements for Neuraxial Procedures Using Tactile Imaging vs Control

Detailed Description
Neuraxial procedures, in which a needle is inserted into the spinal canal through a gap in the vertebrae, are performed at a rate of nearly 13 million per year in the US, across a myriad of diagnostic and therapeutic clinical scenarios.
The standard of care involves manual palpation of the patient's back to detect the spinous processes (SPs) and estimate the location of the interspinous needle insertion site. While providers are trained to perform these procedures with meticulous precision and attention to detail, this technique remains highly inaccurate, often requiring multiple insertion attempts to properly place the needle. These attempts lead to patient pain and complications, such as traumatic taps and post-dural puncture (PDPH) headaches; unpredictable procedure times; and poor facility throughput.
The VerTouch device uses tactile imaging to offer a non-invasive, untethered, non radiation-producing solution for visualizing spinal anatomy in order to identify an ideal location for needle placement in a neuraxial procedure. The device can be used to mark the identified site with a surgical marker, or to begin placement of a needle or introducer at that site.
Study participants will be recruited in two parallel cohorts: the control (palpation) group or the tactile imaging (VerTouch) group, further stratified by procedure setting, including emergency medicine, neurology, and anesthesiology. Once an insertion site is marked with a marker or shallow placement of a needle or introducer, the procedure will continue in the usual manner for subjects in both groups.

End of procedure
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Incidence of first-insertion success
Time Frame: End of procedure

Number of redirections
Time Frame: End of procedure
|
Any forward movement of the needle in a new direction not preceded by withdrawal from the skin, counted until confirmation of spinal canal access can be assessed.
|
End of procedure
|

|
End of procedure
|
Subject discomfort during landmarking
Time Frame: End of procedure

Evaluated using a 10-point Numeric Pain Rating Scale, where 1 is equivalent to no pain and 10 is equivalent to the worst possible pain.
|
End of procedure
|
Provider confidence with the identified insertion site
Time Frame: End of procedure
|
Evaluated using a 1-5 point Numeric Rating Scale where 1 is equivalent to not at all confident and 5 equivalent to completely confident.
