  1. Data are presented as the mean ± SD or median values [range]. There were no differences between the two groups: double group = patients who received combined spinal-epidural anesthesia with the double-space technique; single group = patients who received combined spinal-epidural anesthesia with the single-space technique; total procedure time: time interval between local infiltration to skin and the intrathecal injection; time to readiness: time from intrathecal injection to T4 sensory block; the point of intrathecal injection was taken as time 0 min in both groups
