Effect of Ultrasound Guided Bilateral Thoracolumbar Interfascial Plane (TLIP) Block on Post-operative Opioid Consumption After Lumbar Spine Surgeries. A Randomized Double Blinded Study.
In Brief
A clinical study evaluating Thoracolumbar Interfascial Plane (TLIP) block and I.V drug based multimodal approach for Regional Anesthesia. Completed, enrolled 34 participants across 1 site.
Detailed Summary
The study aims to evaluate the effect of US guided bilateral Thoracolumbar Interfascial plane (TLIP) block performed at the level of the lumbar spine surgery (involving 1 up to 3 adjacent lumbar vertebrae) after induction of general anesthesia and before starting the surgery on postoperative opioid consumption by the patients during the first 24 hours postoperative.

Timeline
Interventions
A 10 cm 21G Stimuplex needle (Braun Medical Inc, Bethlehem, PA, USA) will be inserted in a lateral-to-medial orientation with an approximate angle of 30 degrees to the skin. The needle will then be advanced under real-time in-plane ultrasound guidance through the belly of the LG towards the MF. The needle tip will be directed towards the LG/MF interface deep to the midpoint then a total volume of 20 ml of Bupivacaine 0.25% will be incrementally injected with intermittently repeated negative aspiration. Anterior spread of local anesthetic will be viewed as favourable. The same procedure will be repeated on the left side. The patient will then be disinfected and draped and surgery will be allowed to proceed normally.
A base low dose opioid of 5mg morphine I.V every 8 hours. Rescue analgesia will be given to the patient if reported a VAS equal or more than 4 in the form of I.V morphine in 2.5mg increments till VAS returns to 4 or less in addition to 1 gm of oral acetaminophen every 6 hours
