Sánchez Roldán, M.Á., Mora Granizo, F., Oflidis, V. et al. Optimizing the methodology for saphenous nerve somatosensory evoked potentials for monitoring upper lumbar roots and femoral nerve during lumbar spine surgery: technical note. J Clin Monit Comput 36, 1079–1085 (2022).
  • This study technically advances the desired methodology for the Sap-SEP that includes distal stimulation of the saphenous nerve and the use of two scalp derivations, CPz–cCP and CPz–Fz, for an optimal recording.
  • The distal approach, non-invasive and based on less variable anatomical landmarks, elicits a higher amplitude Sap-SEP without producing leg movement that may interfere with surgery.
  • A more reliable recording of Sap-SEP promotes its application in the operating room, particularly when surgery poses a risk of injury to the femoral nerve, upper lumbar roots, and lumbar plexus.
