Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The percentage of cases in which MEPs in trapezius muscle in cervical spine cases, deltoid muscle in thoracolumbar spine, and abductor digiti minimi muscle in thoracolumbar spine did not decrease by 70% or more in the control MEP amplitude and the operation was started under desflurane anesthesia and the operation was completed | — |
