Caudal Epidural With Non Opioid Adjuvants in Lumbosacral Spine Surgery

Lumbosacral spine surgeries are accompanied with severe postoperative pain which has a negative effect on patients' recovery. Preemptive analgesia before lumbosacral spine surgeries should be implemented to prevent CNS plasticity and to provide effective pain relief. The most common way to provide pain management after spine surgery is the intravenous analgesia. Caudal epidural analgesia can be a highly effective method for postoperative pain relief. The most common way to provide pain management after spine surgery is the intravenous analgesia. Caudal epidural analgesia can be a highly effective method for postoperative pain relief. acting drugs last from 4-8 hours,But this can be prolonged by adding non opioid adjuvants like steroid( dexamethazone,betamethasone), alpha2 agonists (clonidine, dexmedetomidine), or their combination. This study will compare adding different non opioid adjuvants to bupivacaine in caudal epidural for preventive analgesia in lumbosacral spine surgery which can be a part of multimodal analgesia protocol. .
