Randomized Controlled TrialErector spinae block for postoperative pain management in lumbar disc hernia repair.
Lumbar disc herniation is the most common spinal disorder and various less invasive techniques such as microdiscectomy have been described. However, postoperative pain management in patients undergoing discectomy is still commonly inadequate. Erector spinae plane (ESP) block is a relatively easier technique with lower risks of complications, and can be performed to provide postoperative analgesia for various procedures. The current study aimed to determine the effect of ESP block on postoperative analgesia in patients who underwent elective lumbar disc herniation repair surgeries. ⋯ NCT03744689.

Post-thoracotomy pain syndrome (PTPS) is defined as persistent pain following a thoracotomy and has an incidence of 21-61%. Dorsal root ganglion stimulation (DRG-S) is a form of neuromodulation that modulates pain signal transmission to the spinal cord. The aims of this study were to investigate the efficacy of DRG-S for the management of PTPS and to assess the role of thoracic paravertebral blocks (t-PVB) as a tool for prediction of success of DRG-S. ⋯ Our preliminary results show that DRG-S is an effective therapy for PTPS after thoracic surgery. In addition, thoracic paravertebral blocks performed prior to DRG-S correlated with a positive outcome with treatment.
