Spinal and Epidural Anesthesia (Full Version)
This 3D medical animation shows the administration of spinal and epidural anesthesia to a female. For spinal anesthesia, a needle pierces the dura mater covering the spinal cord, injecting anesthetic into the sac of fluid around the spinal cord. For epidural anesthesia, the needle does not pierce the dura mater. Instead, the needle injects anesthetic outside the fluid sac surrounding the spinal cord.
