The Effect of Local Anesthetic Injection Depth on Procedural Pain and Discomfort During Fluoroscopically Guided Lumbar Transforaminal Epidural Injections

An interventional study of 1ml of local anesthetics (1% Lidocaine) were injected into the subcutaneous layer. and 1ml of a local anesthetics (1% idocaine) are first injected into the subcutaneous layer, followed by 3~4ml of local anesthetics to the muscle layer along the expected needle pathway. in Lumbar Radiculopathy Due to Spinal Nerve Compression, sponsored by Yonsei University. Completed at 1 site in Korea, Republic of. Open to participants aged 20 Years to 80 Years. Per ClinicalTrials.gov, last updated 2019-01-11.

Study summary

Lumbar Transforaminal Epidural Injection is helpful for the treatment of lumbosacral radicular pain. But needle handling during the procedure may cause pain and discomfort to the patient. At the local skin anesthesia step, local anesthetics injection to the muscle layer along the needle pathway as well as the subcutaneous layer may reduce the procedural pain. In addition, it can reduce the injection site pain that may occur after the procedure.

Read the detailed description
  1. A planned Fluoroscopically Guided Lumbar Transforaminal Epidural Injection should be performed after receiving the informed consent of the patient.
  2. This study is single-blind because it is not possible to blind the practitioner performing the injection.
  3. Subjects were randomly assigned to the subcutaneous anesthesia group (group A) and the muscle anesthesia group (group B) by a random random number table, and the possibilities for belonging to any group were all the same and can not be artificially controlled by researchers.
  4. After the procedure, a resident who does not know of this study records the patient's pain and discomfort. and on follow-up visits, post injection site pain is checked.
  5. Because of the large difference between the skilled and unskilled patients, the procedure in this study is performed by only one skilled practitioner

What researchers measure

Primary outcomes

  1. Procedural Pain score (NRS)

    Numeric Rating Scale(NRS) score : from 0 (No pain) to 10 (worst pain imaginable)

    Time frame: Immediately after the procedure

Secondary outcomes

  1. At the next outpatient visit, whether the injection site pain(Yes) or not(No)

    At the next outpatient visit, subjects asked about injection site pain (Yes / No) after the last injection.

    Time frame: 2 weeks

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Oct 2017 to primary completion in Feb 2018, 4 months.

Of 141 non-industry interventional studies with no phase under Pain, Procedural, half reached primary completion within 7 months of starting (the median), counting those still running; a quarter within 3 and three quarters within 15. This study's 4 months is below that.

Counting every sponsor, half of 141 studies reached it within 7 months; a quarter within 3 and three quarters within 15.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 11, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
