Etomidate versus Propofol as Induction Agents in Patients Undergoing Decompressive Procedures for Cervical Compressive Myelopathy with and without Impaired Heart Rate Variability

Abstract

Background Patients with cervical compressive myelopathy (CCM) are known to have autonomic dysfunction, which can impact surgical outcomes. In such patients, screening patients for heart rate variability (HRV) may enable the anesthesiologist to predict hypotension, thereby attempting to modify the anesthetic technique. This study aimed to compare the hemodynamic changes in CCM patients between propofol and etomidate induction.
