This regional anesthesia training tool is the only training aid that demonstrates the distribution and behaviors of medications with various densities within the intrathecal space post medication injection. Current spinal injection task trainers provide only for simulated confirmation of correct needle insertion and placement through loss of resistance. Additionally, this product allows the visualization of how changes in patient positioning may affect medication distribution. Its purpose and continued development is to advance patient safety during the pratice of intrathecal regional anesthesia.
