Ultrasound Guided Regional Anesthesia
The Lumbar Spine Ultrasound module is aimed at teaching ultrasound-guided regional anesthesia for the lumbar spine. It includes an animation illustrating the flexion of the lumbar spine during patient positioning to open the intervertebral spaces, facilitating the insertion of needles into the spinal canal. The module also contains a section teaching the sonoanatomy of the lumbar spine and a final section currently under development which will allow users to perform a simulated ultrasound of the lumbar spine in preparation for spinal anesthesia.
- An animation of the spine in sitting and forward flexion
- Lateral and dorsal views of the spine
- Comparison of lumbar spine cross-sections from the sacrum to L1 with ultrasound in transverse and longitudinal paramedian scan
- Angling views through each interspace of the lumbar spine
Ultrasound (in development)
- Users scan a virtual patient to find an appropriate interspace to perform regional anesthesia
