Intravenous Dexamethasone and Dexmedetomidine on the Analgesic Efficacy of Erector Spinae Plane Block

Dexmedetomidine Clinical Trial

Official title: Intravenous Dexamethasone and Dexmedetomidine on the Analgesic Efficacy of Erector Spinae Plane Block for Posterior Lumbar Interbody Fusion Surgery

Status Completed

Clinical Trial Summary

Patients having lumbar spinal fusion often complain about severe postoperative pain and postoperative rehabilitation process can be affected negatively. Postoperative pain that cannot be well controlled may lead to delayed mobilization, pulmonary and thromboembolic complications, prolonged hospital stays, and chronic pain syndromes. Pain after spinal surgery can arise from several different tissues, such as the vertebrae, disks, ligaments, dura, facet joint, muscle, fascia, and subcutaneous and cutaneous tissues. Ultrasound-guided lumbar erector spinae plane block (ESPB) has been shown to reduce postoperative pain in patients undergoing posterior lumbar interbody fusion (PLIF). However, the duration of analgesia after single-shot ESPB with commonly used local anesthetics is reported to be no more than 12 h, which often not long enough to provide satisfactory postoperative pain relief, as the pain typically lasts for several days. Compared with perineural route, intravenous additives to local anesthetics are commonly accepted as its safety and efficiency have been reported. Moreover, co-administration of intravenous dexamethasone and dexmedetomidine significantly prolonged the time to first rescue analgesic request after single-shot interscalene brachial plexus block. However, more data are needed especially for lumbar ESPB.
