STUDY DESIGN: Clinical case series. OBJECTIVE: To study the combined use of modifications of stimulation methods and adjustments of anesthetic regimens on the reliability of motor-evoked potential (MEP) monitoring in a large group of children undergoing spinal surgery. SUMMARY OF BACKGROUND DATA: Monitoring of MEPs is advocated during spinal surgery, but systematic data from children are sparse. METHODS: A total of 134 consecutive procedures in 108 children 6 years and in 86% (18 of 21) in children <6 years of age. CONCLUSIONS: Combining spatial facilitation with a TES protocol improved monitoring of corticospinal motor pathways during spinal surgery in children. A ketamine-based anesthetic technique was preferred in children <6 years of age.
