Postoperative Pain Control in AIS Using Liposomal Bupivacaine vs. 0.25% Bupivacaine With Epinephrine

Postoperative Pain Control in AIS Using Liposomal Bupivacaine vs. 0.25% Bupivacaine

A randomized controlled trial (RCT) investigating whether the local anesthetic injection of liposomal bupivacaine during posterior spinal fusion (PSF) for AIS is more effective in reducing acute postoperative opioid consumption compared to an equal volume injection of 0.25% bupivacaine with epinephrine for patients aged 10 to 17, with 128 patients randomly assigned to one of two arms: liposomal bupivacaine or 0.25% bupivacaine with epinephrine.
