A Clinical Comparison between Single-Space Technique and Double-Space Technique for Combined Spinal and Epidural Anesthesia.

Background: Combined spinal and epidural anesthesia (CSEA) is commonly performed by double space technique (DST) and single space segment technique (SST) or needle-through-needle technique (NNT).

Aims And Objectives: We designed a double-blind randomized controlled study to compare the effect of the double-space technique with that of the single-space technique on time required by the procedure, the number of attempts, and a level of sensory, side effects and cost-effectiveness.

Materials And Methods: Patients undergoing elective lower abdominal and lower limb surgeries under regional anesthesia were randomized to receive CSEA with either the double-space technique (double group, = 30) or the single-space technique (single group, = 30).
