Summary

This study looks at two ultrasound-guided nerve blocks used to manage pain after lumbar spine surgery: the classic TLIP block and the QIP block. Adults aged 18-65 having elective lumbar discectomy will receive one of these blocks as part of their routine care. Researchers will track how much opioid pain medication is needed in the first 24 hours, when pain medication is first requested, pain scores at several time points, and any side effects. The goal is to see which block provides better pain relief and reduces opioid use.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Two ultrasound-guided nerve blocks (TLIP and QIP) using bupivacaine, a local anesthetic
What this could lead to
If one block proves better, it could become the preferred method to reduce pain and opioid use after lumbar spine surgery.
What could go wrong
This is a small observational study, not randomized, so results may be influenced by patient differences. Blocks may not work equally for everyone and carry rare risks like infection or nerve damage.
