Comparing curved and straight needles for S1 epidural injections
A Comparison of Intravascular Penetration With Curved Needle and Straight Needle During Sacral 1 Transforaminal Epidural Block
This study is testing whether using a curved needle or a straight needle for S1 epidural injections makes a difference in how often the needle accidentally enters a blood vessel.

What this trial studies
This observational study aims to compare the rate of intravasation during S1 transforaminal epidural injections using either a curved needle or a straight needle. Participants will be randomly assigned to receive the injection with one of the two needle types, and the researchers will monitor and compare the intravasation rates between the groups. The study seeks to determine if the choice of needle affects the likelihood of intravascular penetration during the procedure.
Who should consider this trial
Good fit: Ideal candidates are patients scheduled for a lumbar 1 epidural nerve block at Kyungpook National University Hospital.
Not a fit: Patients with allergies to local anesthetics or steroids, or those with a bleeding tendency or infection symptoms in the sacroiliac region may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved safety and efficacy in administering S1 transforaminal epidural injections.
How similar studies have performed: While similar studies have explored needle types in various contexts, this specific comparison of curved versus straight needles in S1 injections is relatively novel.
