Abstract
We compared the cephalad spread of analgesia using two methods of combined spinal epidural anesthesia (CSE) for cesarean section (c-section). All patients receiving CSE had good analgesia. Although patients receiving epidural injection just after spinal anesthesia had significantly higher cephalad spread of analgesia than patients receiving epidural injection 10min after spinal anesthesia, cephalad spread of analgesia after epidural injection was almost the same in both groups. There were no significant differences in the incidences of hypotension, nausea and dyspnea between groups. In conclusion, epidural injection just after spinal anesthesia is safe and preferable in c-section.
