Effects of dexmedetomidine combined with erector spinae plane block on intraoperative neuromonitoring during surgical correction for adult spinal deformity.

ABSTRACT: We aim to explore the effects of the erector spinae plane block (ESPB) technique combined with dexmedetomidine administered systemically on somatosensory- and/or motor- evoked potential (SSEP and/or MEP) during surgical correction for adult spinal deformity (ASD). 88 patients were randomly allocated to two groups: the propofol-remifentanil based total intravenous anesthesia (TIVA) group (Group T), and the dexmedetomidine group (Group DE), which received dexmedetomidine intravenously at a rate of 0.5 μg kg^-1 h^-1 as an adjuvant to TIVA, along with bilateral bi-level single-shot ESPB using 0.2% ropivacaine. Bilateral bi-level single-shot ESPB was performed in Group DE. The depth of anesthesia was adjusted by varying the propofol infusion rate based on the bispectral (BIS
