Thoracolumbar Interfascial Plane Block in Spinal Surgery: A Systematic Review with Meta-Analysis

As the thoracolumbar interfascial plane (TLIP) block may be a promising alternative in spinal surgery, there is a need for timely meta-analysis of this method’s effectiveness in different medical outcomes. The meta-analysis of 6 randomized controlled studies on the application of TLIP block in spinal surgery was performed under the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. The primary outcome used for comparison was the mean difference (MD) of pain intensity scores at rest/in motion between patients receiving TLIP block and those receiving no block care. Our analysis favors TLIP block over no block (control group) for pain intensity at rest (MD with 95% confidence interval [CI] is −1.14 [−1.29, −0.99], P value
