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.

Avoiding the Internal Mammary Artery During Parasternal Blocks: Ultrasound Identification and Technique Considerations.
Fascial plane chest wall blocks are an integral component to optimal multimodal postoperative analgesia in breast and cardiothoracic surgery, facilitating faster functional recovery and earlier discharge. Pectoral nerves block and serratus plane block have been used to treat postsurgical pain after breast and cardiothoracic surgeries; however, they cannot be used to anesthetize the anterior chest wall. Ultrasound parasternal block, or pectointercostal fascial block and transversus thoracis muscle plane block are two novel ultrasound-guided anesthetic and analgesic techniques that block the anterior cutaneous branches T2 to T6 intercostal nerves, providing anesthesia and analgesia to the anterior chest wall. ⋯ For this reason, ultrasound parasternal block also could be performed by inexperienced anesthesiologists. Although ultrasound parasternal block is more superficial, its superiority in terms of safety is yet to be proven. Additional studies are warranted to validate the authors' hypothesis.

Postoperative pain in spine surgery is an issue. Erector spinae plane block (ESPB) may reduce such postoperative pain, but its usefulness has never been evaluated in the specific context of trauma surgery. We thus studied the effect of bilateral ultrasound-guided ESPB on postoperative pain and opioid requirement after percutaneous lumbar arthrodesis for trauma. ⋯ In this pilot study, compared with standard analgesia, ESPB reduced opioid requirement and postoperative pain after percutaneous lumbar arthrodesis for trauma. A randomized controlled trial is required to prove this effectiveness.
