Summary
This was a single-blind, randomized controlled trial. Sixty-six patients who underwent caudal
epidural injection were randomized into the vapocoolant spray group or local infiltration
group. Before the insertion of a 20-gauge spinal needle, the subcutaneous tissue was
infiltrated with 3 ml of 2% lidocaine in the local infiltration group and vapocoolant spray
was applied just before the spinal needle insertion in the spray group. 100-mm visual analog
scale to evaluate the pain intensity of spinal needle insertion and a five-point Likert scale
for patient satisfaction and preference for repeated use were compared between the two
groups.
