Randomized Controlled Trial Comparative Study
Erector spinae plane block versus quadratus lumborum block for postoperative analgesia after laparoscopic nephrectomy: A randomized controlled trial.
We compared the analgesic effects of erector spinae plane block versus quadratus lumborum block following laparoscopic nephrectomy. ⋯ Compared with quadratus lumborum block, erector spinae plane block provided better analgesia as manifested by lower opioid consumption and pain intensity for up to 24 h after laparoscopic nephrectomy.

Both endocannabinoid (EC) and endogenous opioid systems are involved in nociceptive processing and may work together synergistically based on preclinical models. This study evaluated the interactive effects of preoperative beta-endorphin (BE) concentrations (a key analgesic endogenous opioid) in cerebrospinal fluid (CSF) and ECs (CSF and plasma 2-arachidonoylglycerol and plasma anandamide) on postoperative opioid use and pain intensity in a prospective cohort of n = 112 pregnant patients undergoing scheduled cesarean delivery. Maternal blood and CSF samples were collected preoperatively for BE and EC assays. ⋯ Further exploration of interactions between EC and endogenous opioid inhibitory systems as they influence responses to opioid analgesics in other clinical pain populations may help guide the development of precision pain management approaches. PERSPECTIVE: In the postoperative setting of patients undergoing cesarean delivery, elevated ECs were linked to reduced outpatient opioid analgesic use in individuals who had low endogenous opioid concentrations in CSF. Further exploration of interactions between these 2 inhibitory systems as they impact responses to pain management interventions appears warranted.

The management of cancer-related pain in patients with opioid use disorder (OUD) remains complex and often challenging for clinicians and patients. There is currently a paucity of data to guide best practices, and the evidence that exists is variably applied. In this hospital-based questionnaire, we sought to understand the variation in practice patterns among clinicians in palliative medicine, addiction medicine, and hospital medicine, in caring for this complex patient population. ⋯ There was also a significant difference in postdischarge subspecialty follow-up. Furthermore, the findings suggest that buprenorphine and methadone may be underutilized in this population. Patients and clinicians may benefit from additional support and standardization of practices to best manage coexisting cancer-related pain and OUD.
