Local Vancomycin Effectively Reduces Surgical Site Infection at Implant Site in Rodents
Conclusions This study suggests that local vancomycin should be added to systemic vancomycin to reduce SSI with cardiac pacemaker, defibrillator, implantable pulse generator of neurostimulator, or intrathecal pump implants. (Source: Regional Anesthesia and Pain Medicine)

Long-Term Safety and Efficacy of Minimally Invasive Lumbar Decompression Procedure for the Treatment of Lumbar Spinal Stenosis With Neurogenic Claudication: 2-Year Results of MiDAS ENCORE
Conclusions MILD showed excellent long-term durability, and there was no evidence of spinal instability through 2-year follow-up. Reoperation and spinal fracture rates are lower, and safety is higher for MILD versus other lumbar spine interventions, including interspinous spacers, surgical decompression, and spinal fusion. Given the minimally invasive nature of this procedure, its robust success rate, and durability of outcomes, MILD is an excellent choice for first-line therapy for select patients with central spinal stenosis suffering from neurogenic claudication symptoms with hypertrophic ligamentum flavum. Clinical ...

Hypertonic Sodium Chloride Preinjectate Increases In Vivo Radiofrequency Ablation Size: Histological and Magnetic Resonance Imaging Findings
Conclusions This study validates the ability of hypertonic saline to increase in vivo RF lesion size. With further refinement, MRI may be a viable method to assess RF lesion size. (Source: Regional Anesthesia and Pain Medicine)

The Impact of Tobacco Cigarette Smoking on Spinal Cord Stimulation Effectiveness in Chronic Spine–Related Pain Patients
Background and Objectives Despite the observation that select nicotine receptor agonists have analgesic effects, smokers report higher pain scores and more functional impairments than lifelong nonsmokers, attributable to exaggerated stress responses, receptor desensitization, and altered pharmacokinetics compounded by accelerated structural damage resulting from impaired bone healing, osteoporosis, and advancement of disk disease. We hypothesized that smoking diminishes the analgesic response to spinal cord stimulation (SCS) in patients with chronic spine–related pain conditions. Methods A retrospective cohort study...

A Novel Technique of Ultrasound-Guided Selective Mandibular Nerve Block With a Lateral Pterygoid Plate Approach: A Cadaveric Study
Conclusions This cadaveric study suggests that this novel technique, using an LPP approach under ultrasound guidance, is helpful for selective mandibular nerve block, with high accuracy and feasibility. Further studies are required to establish its safety and efficacy for clinical application. Clinical Trial Registration This study was registered at the Thai Clinical Trials Registry (ClinicalTrials.in.th), identifier TCTR20160601004. (Source: Regional Anesthesia and Pain Medicine)

Erector Spinae Plane Block Versus Retrolaminar Block: A Magnetic Resonance Imaging and Anatomical Study
Conclusions The clinical effect of ESP and retrolaminar blocks can be explained by epidural and neural foraminal spread of local anesthetic. The ESP block produces additional intercostal spread, which may contribute to more extensive analgesia. The implications of these cadaveric observations require confirmation in clinical studies.

A Cadaver Study Investigating Structures Encountered by the Needle During a Retroclavicular Approach to Infraclavicular Brachial Plexus Block
Conclusions The suprascapular nerve is consistently in the path of the block needle posterior to the clavicle. This raises the possibility of risk of injury to the suprascapular nerve when using this approach to the brachial plexus. Vascular injury is also possible deep to the clavicle, and because of the noncompressible location, caution is advised in patients with disordered coagulation.

Rhomboid Intercostal and Subserratus Plane Block: A Cadaveric and Clinical Evaluation
Conclusions Our preliminary cadaveric and clinical data suggest that RISS block anesthetizes the lateral cutaneous branches of the thoracic intercostal nerves and can be used in multiple clinical settings for chest wall and upper abdominal analgesia. (Source: Regional Anesthesia and Pain Medicine)

Selective Suprascapular and Axillary Nerve Block Versus Interscalene Plexus Block for Pain Control After Arthroscopic Shoulder Surgery: A Noninferiority Randomized Parallel-Controlled Clinical Trial
Conclusions Suprascapular-axillary nerve block is inferior to ISB in terms of analgesia and opioid requirement in the immediate period after arthroscopic shoulder surgery but is associated with a lower incidence of dyspnea and discomfort. The difference in pain and opioid consumption gradually decreases as the blocks wear off in order to reach similar pain scores during the first postoperative night and at 24 hours. Clinical Trial Registration This study was registered at ClinicalTrials.gov, identifier NCT02415088. (Source: Regional Anesthesia and Pain Medicine)

Perineural Versus Systemic Dexamethasone in Front-Foot Surgery Under Ankle Block: A Randomized Double-Blind Study
Conclusions In front-foot surgery, perineural and systemic administrations of dexamethasone are equivalent for postoperative pain relief when used as an adjuvant to ropivacaine ankle block.

Lack of Association Between Levels and Length of Intraoperative Controlled Hypotension and Acute Kidney Injury in Total Hip Arthroplasty Patients Receiving Neuraxial Anesthesia
Conclusions In this study, AKI was rare. We found a lack of association between IOH and postoperative AKI in a setting where neuraxial anesthesia–facilitated IOCH is routinely practiced. Therefore, it seems prudent for future research and clinical guidelines to consider the distinction between inadvertent and controlled hypotension. (Source: Regional Anesthesia and Pain Medicine)

Reduced Hemidiaphragmatic Paresis With a “Corner Pocket” Technique for Supraclavicular Brachial Plexus Block: Single-Center, Observer-Blinded, Randomized Controlled Trial
Conclusions The incidence of hemidiaphragmatic paresis was effectively reduced when local anesthetic was injected primarily in the corner pocket during right-sided SCBPB. However, the 28% incidence of hemidiaphragmatic paresis associated with the corner pocket technique may still represent a prohibitive risk for patients with preexisting pulmonary compromise.
