The effect of scoliosis on surface landmarks for lumbar plexus block: a magnetic resonance imaging-based retrospective case-control series.
Degenerative scoliosis (DS) may affect surface landmarks for performance of lumbar plexus (LP) block. We hypothesized the extent of any difference in surface landmarks could be calculated by a formula based on measured degree of DS, body mass index, sex, and age. ⋯ There is a larger degree of lateral deviation of the LP on the concave side of scoliosis compared to medial deviation on the convex side. These deviations remained consistent irrespective of the direction of scoliosis. A review of the imaging studies and preprocedural ultrasound assessment of anatomy should be strongly considered prior to needle puncture. In patients with severe DS, an alternative approach may be considered to avoid the possibility of visceral organ injury.

Ultrasound-Guided Cervical Nerve Root Block for the Treatment of Acute Cervical Herpes Zoster: A Randomized Controlled Clinical Study.
To evaluate the efficacy and safety of ultrasound-guided cervical nerve root block (CRB) on acute pain and its preventive effects on post-herpetic neuralgia (PHN) in patients with cervical herpes zoster (HZ). ⋯ Ultrasound-guided CRB represented an early intervention and preventive strategy to reduce the BOI due to acute HZ in the cervical dermatome region, and might be feasible to reduce the incidence of PHN.

Randomized Controlled TrialRetrobulbar dexmedetomidine in pediatric vitreoretinal surgery eliminates the need for intraoperative fentanyl and postoperative analgesia: A randomized controlled study.
This study evaluated the efficacy of retrobulbar ropivacaine plus dexmedetomidine compared with systemic fentanyl in pediatric vitreoretinal (VR) surgery. ⋯ Retrobulbar dexmedetomidine as an adjuvant to ropivacaine is a safe and effective alternative to systemic fentanyl. This regimen provides better pain management, hemodynamic stability, and stress response suppression in pediatric VR surgery.

ReviewHow to Use Pectoral Nerve Blocks Effectively—An Evidence-Based Update
Since the original description in 2011, the array of pectoral nerve blocks has evolved. The pectoral nerve (PECS) block in conjunction with general anesthesia can decrease an additional analgesic in perioperative period for breast cancer surgeries. Current literature on the PECS block has reported 3 several types (PECS I, PECS II, and serratus plane blocks). ⋯ Therefore, some studies have reported its ability to block the anterior branches of the intercostal nerve. PECS block is an effective analgesic tool for the anterolateral chest. In particular, the PECS block can provide more effective analgesia for breast cancer surgery.

Case ReportsErector spinae plane block combined with a novel technique for selective brachial plexus block in breast cancer surgery -a case report.
The breast is innervated by the intercostal nerves and the brachial plexus. We propose a technique to perform breast surgery without general anesthesia using the erector spinae plane (ESP) block and selective block of four nerves that arise from the brachial plexus innervate the breast and the axilla (SBP block). ⋯ SBP is a novel block that selectively blocks branches of the brachial plexus that innervate the breast.
