Chun EH, et al. - Given that either a single-space technique or a double-space technique can be used to perform combined spinal-epidural anesthesia (CSEA) for cesarean section, researchers compared the double-space technique vs the single-space technique with respect to the effect on sensory block level and side effects by performing this double-blind randomized controlled study. Participants were parturients receiving regional anesthesia for elective cesarean section, who were randomly allocated to receive CSEA with either the double-space technique (double group, n = 20) or the single-space technique (single group, n = 20). Findings revealed that the double-space technique and the single-space technique for CSEA did not differ in terms of intraoperative variables but likely benefits of double-space CSEA for cesarean section were suggested in terms of controlling postoperative pain and improving parturient satisfaction.
