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.

Randomized Controlled Trial Comparative Study
A comparison of effects of scalp nerve block and local anesthetic infiltration on inflammatory response, hemodynamic response, and postoperative pain in patients undergoing craniotomy for cerebral aneurysms: a randomized controlled trial.
The purpose of this study was to compare the effects of scalp nerve block (SNB) and local anesthetic infiltration (LA) with 0.75% ropivacaine on postoperative inflammatory response, intraoperative hemodynamic response, and postoperative pain control in patients undergoing craniotomy. ⋯ Preoperative SNB attenuated inflammatory response to craniotomy for cerebral aneurysms, blunted the hemodynamic response to scalp incision, and controlled postoperative pain better than LA or routine analgesia.

Comparative StudyUltrasound-guided selective nerve root block versus fluoroscopy-guided interlaminar epidural block for the treatment of radicular pain in the lower cervical spine: a retrospective comparative study.
Recent studies have compared the therapeutic efficacy and safety of the procedure using ultrasound and fluoroscopy. However, there are no published studies comparing the therapeutic efficacy and safety of fluoroscopy (FL)-guided cervical interlaminar epidural steroid injection (CIESI) with that of ultrasound (US)-guided selective nerve root block (SNRB). This study aimed to compare the mid-term effects and advantages of US-guided SNRB with FL-guided CIESI for radicular pain in the lower cervical spine through assessment of pain relief and functional improvement. ⋯ Our results suggest that, compared with FL-guided CIESI, US-guided SNRB requires a shorter administration duration while providing similar pain relief and functional improvements.

Regional anesthesia and pain management have experienced advances in recent years, especially with the advent of fascial plane blocks. The erector spinae plane block is one of the newest techniques to be described. In the past two years, publications referring to ESP block have increased significantly. ⋯ The single-shot was the most frequently used technique. As described in the articles published to date, the technique is easy to perform and has a low rate of complications. However, despite the effectiveness of the technique, further studies are necessary to obtain more evidence of its actions.

There is confusion regarding the spread of intraneurally injected local anesthetic agents during regional anesthesia. The aim of this research was to deliberately inject a marker that does not leave the neural compartment into which it is injected, and then to study the longitudinal and circumferential spread and possible pathways of intraneural spread. ⋯ After deliberate intraneural injection, longitudinal and circumferential extrafascicular spread occurred in all instances in the neural compartments that contained adipocytes, but not in the relatively solid endoneurium of the fascicles.
