Summary

This study compares two techniques used during lumbar fusion surgery to see which one better reduces bleeding and pain after the operation. About 62 adults having back fusion surgery will be randomly assigned to receive either a large-volume injection of numbing medicine with a vessel-shrinking drug around the spine (PVI) or a smaller injection near the back muscles (ESP). The goal is to find which method leads to less blood loss and better pain control after surgery.
