Intraoperative Retrolaminar Block as Opioid Free Anesthesia After Posterior Lumber Spine Discectomy

Opioid-free intraoperative protocols have been successfully used in specific surgical populations with equal or superior results to classic general anesthetic approaches. In instances where opioid-free anesthesia may not be entirely feasible, there exists a continually growing body of evidence that the modern anesthesiologist has a potent pharmacologic and regional anesthetic arsenal that can reduce the amount of opioids required to effectively treat pain.
