Summary

This study compares two types of nerve blocks for pain after repeat lumbar spine surgery. 64 adults aged 40-70 will receive either a caudal epidural block alone or a combined lumbar sympathetic block with caudal epidural. Pain levels will be measured before and after surgery to see which method provides better relief.

What this could mean

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

Active substance
nerve block (caudal epidural or combined lumbar sympathetic block with caudal epidural)
What this could lead to
If it works, this could point toward a better way to manage pain after repeat back surgery, reducing the need for strong painkillers.
What could go wrong
This is a small, early-stage trial with only 64 participants. The results may not apply to everyone, and nerve blocks carry risks like infection or temporary numbness.
