A Systematic Scoping Review of Peridelivery Pain Management for Pregnant People With Opioid Use Disorder: From the Society for Obstetric Anesthesia and Perinatology and Society for Maternal Fetal Medicine.
The prevalence of pregnant people with opioid use disorder (OUD), including those receiving medications for opioid use disorder (MOUD), is increasing. Challenges associated with pain management in people with OUD include tolerance, opioid-induced hyperalgesia, and risk for return to use. Yet, there are few evidence-based recommendations for pain management in the setting of pregnancy and the postpartum period, and many peripartum pain management studies exclude people with OUD. ⋯ Opinions are conflicting on the utility and disutility of various analgesic interventions. Studies generating high-quality evidence on this topic are needed to inform care for pregnant people with OUD. Specific research areas are identified, including utility and disutility of short-term opioid use for postpartum pain management, role of continuous wound infiltration and truncal nerve blocks, nonpharmacologic analgesia options, and the best methods to support psychosocial aspects of pain management.

ReviewParasternal Intercostal Nerve Blocks in Patients Undergoing Cardiac Surgery: Evidence Update and Technical Considerations.
In the Enhanced Recovery After Surgery era, parasternal intercostal nerve block has been proposed to improve pain control and reduce opioid use in patients undergoing cardiac surgery. However current literature has reported conflicting evidence about the effect of this multimodal pain management, as procedural variations might pose a significant bias on outcomes evaluation. In this setting, the infiltration of the parasternal plane into 2 intercostal spaces, second and fifth, with a local anesthetic spread under or above the costal plane with ultrasound guidance, seem to be standardized in theory, but significant differences might be observed in clinical practice. ⋯ A trend toward reduced intensive care unit stay or duration of mechanical ventilation should be confirmed by adequately powered randomized trials or registry studies. Differences in operative technique might impact outcomes and, therefore, standardization of the procedure plays a pivotal role before reporting specific outcomes. Parasternal plane blocks might significantly improve outcomes of cardiac surgery with full median sternotomy, and should be introduced comprehensively in Enhanced Recovery After Surgery protocols.

Randomized Controlled Trial
Motor-sparing peripatellar plexus block provides noninferior block duration and complete block area of the peripatellar region compared with femoral nerve block: a randomized, controlled, noninferiority study.
Developing adequate regional anaesthesia for knee surgeries without affecting lower limb mobilization is crucial to perioperative analgesia. However, reports in this regard are limited. We proposed a technique for ultrasound-guided peripatellar plexus (PP) block. Compared with the femoral nerve (FN) block, we hypothesized that this technique would provide a noninferior block duration and a complete cutaneous sensory block in the peripatellar region without affecting lower limb mobilization. An investigation was conducted to verify our hypothesis in cadavers and volunteers. ⋯ Ultrasound-guided PP block is a feasible technique. Compared with FN block, PP block provides noninferior block duration and complete blocking of the peripatellar region without affecting lower limb mobilization.
