Does a ThoracoLumbar Interfacial Plane (TLIP) Block With Liposomal Bupivacaine Provide TLIP Block in Spinal Surgery

Does a ThoracoLumbar Interfacial Plane (TLIP) Block With Liposomal Bupivacaine Provide Extended Post-operative Analgesia Following Spinal Surgery

The investigators are looking to recruit patients into a study demonstrating the effectiveness of a superficial nerve block involving the thoracolumbar interfascial plane (TLIP) in reducing postoperative pain in those undergoing spinal surgery

Patients undergoing spine surgery with or without fusion experience a great deal of pain especially in the first 3 days after surgery. Spine surgeons are looking for ways to reduce the pain that you experience. Anesthesiologists have introduced a procedure, called a "TLIP block" to provide pain relief. The block involves injecting local anesthetic (numbing pain medication) in the lower back around the site of the surgery. This block has been used by other surgeons for other types of surgeries in the past and has been shown to work.

To determine how effective the block is, the investigators are conducting this investigational study where pain severity in patients who receive one of 2 kinds of local anesthetic or placebo are compared
