A Study of the Clinical Effects of Sequential Combined Spinal Epidural Anesthesia and Spinal Anesthesia in Patients Undergoing Orthopedic Surgeries.

Background: In orthopedic surgeries, there has been an increase in the usage of the neuraxial blockade to provide excellent surgical conditions and prolonged postoperative analgesia. The introduction of the sequential combined spinal epidural anesthesia (SCSEA) technique provides benefits for both spinal anesthesia (SA) and epidural anesthesia. The focus of this study was to analyze the time needed to attain a desired level of sensory block, to compare the period of sensory block, and to study the intraoperative hemodynamics in the SCSEA and SA groups.
