There were no differences between the two groups (P = 0.248); SBP = systolic blood pressure; 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. The point of intrathecal injection was taken as time 0 min for both groupsBack to article page
