Nerve-Zapping device could speed up Post-Surgery waking, but study never started

This study planned to test a noninvasive device that stimulates the vagus nerve through the skin to see if it could help people recover consciousness more quickly after anesthesia. The researchers wanted to enroll adults undergoing lumbar spine surgery and measure how fast they woke up, as well as whether the device reduced delirium and depression. However, the study was withdrawn before any participants were enrolled, so no results are available.
