Randomized Controlled Trial
The Effect of Ultrasound-guided Bilateral Erector Spinae Plane Block With and Without Dexmedetomidine on Intraoperative and Postoperative Pain in Laparoscopic Cholecystectomies: A Randomized, Controlled, Double-blind, Prospective Trial.
Laparoscopic cholecystectomy is the most common surgical procedure performed in the Western world. While it is performed with minimally invasive procedures, patients often complain of moderate to severe postoperative pain, and the role of the anesthesiologist for its effective management remains crucial. Modern anesthesiology practices have embraced trunk blocks which can contribute to perioperative, multimodal analgesia. There is emerging literature about the favorable effect of erector spinae plane block in the reduction of pain after laparoscopic cholecystectomy. ⋯ Erector spinae plane block performed either with ropivacaine or with a combination of ropivacaine and dexmedetomidine is a novel and safe method, which was found to be more effective compared to standard analgesia protocols in patients undergoing laparoscopic cholecystectomy and thus, it can improve the quality of perioperative analgesia.

COMPARISON OF ULTRASOUND-GUIDED ERECTOR SPINAE PLANE BLOCK WITH INTERCOSTAL NERVE BLOCK FOR TRAUMA-ASSOCIATED CHEST WALL PAIN.
Pain associated with chest wall trauma is a major issue in the emergency department (ED). However, it may be challenging to select among the various analgesic procedures. ⋯ Ultrasound-guided ESPB was superior to ICNB regarding pain control during the ED stay period of patients with painful chest wall trauma. We recommend ESPB in the ED for pain control in blunt or penetrating thoracic trauma.

Animal and human studies have shown that exercise prior to nerve injury prevents later chronic pain, but the mechanisms of such preconditioning remain elusive. Given that exercise acutely increases the formation of free radicals, triggering antioxidant compensation, we hypothesized that voluntary running preconditioning would attenuate neuropathic pain by supporting redox homeostasis after sciatic nerve injury in male and female rats. We show that 6 weeks of voluntary wheel running suppresses neuropathic pain development induced by chronic constriction injury across both sexes. ⋯ The protective effects of prior voluntary wheel running were mediated by Nrf2, as suppression was abolished across both sexes when Nrf2 activation was blocked during the 6-week running phase. This study provides insight into the mechanisms by which physical activity may prevent neuropathic pain. Preconditioning by voluntary wheel running, terminated prior to nerve injury, suppresses later neuropathic pain in both sexes, and it is modulated through the activation of Nrf2-antioxidant signaling.
