The Neurostimulation Appropriateness Consensus Committee (NACC)®: Recommendations for Spinal Cord Stimulation Long-Term Outcome Optimization and Salvage Therapy.

Introduction: The International Neuromodulation Society (INS) has recognized a need to establish best practices for optimizing implantable devices and salvage when ideal outcomes are not realized. This group has established the Neurostimulation Appropriateness Consensus Committee (NACC)® to offer guidance on matters needed for both our members and the broader community of those affected by neuromodulation devices.

Materials And Methods: The executive committee of the INS nominated faculty for this NACC® publication on the basis of expertise, publications, and career work on the issue.

Randomized Placebo-Controlled Trial of 60-Day Percutaneous Peripheral Nerve Stimulation Treatment Indicates Relief of Persistent Postoperative Pain, and Improved Function After Knee Replacement.

Objectives: Total knee arthroplasty (TKA) is an effective surgery for end-stage knee osteoarthritis, but chronic postoperative pain and reduced function affect up to 20% of patients who undergo such surgery. There are limited treatment options, but percutaneous peripheral nerve stimulation (PNS) is a promising nonopioid treatment option for chronic, persistent postoperative pain. The objective of the present study was to evaluate the effect of a 60-day percutaneous PNS treatment in a multicenter, randomized, double-blind, placebo-controlled trial for treating persistent postoperative pain after TKA.

Pain and Opioid use Following Total Knee Arthroplasty: Psycho-Social Factors are More Predictive Than Pharmacogenomics.

Background: This prospective, observational study was designed to assess the phenotype variation of the genes associated with pain and opioid use following total knee arthroplasty (TKA) in comparison to psycho-social elements.

Methods: Preoperative demographic data and Patient-Reported Outcomes Measurement Information System-43 scores were obtained on 305 elective TKA patients. Patient visual analog scale pain scores and opioid use were extracted from the hospital record.

Multiorganizational consensus to define guiding principles for perioperative pain management in patients with chronic pain, preoperative opioid tolerance, or substance use disorder.

Significant knowledge gaps exist in the perioperative pain management of patients with a history of chronic pain, substance use disorder, and/or opioid tolerance as highlighted in the US Health and Human Services Pain Management Best Practices Inter-Agency Task Force 2019 report. The report emphasized the challenges of caring for these populations and the need for multidisciplinary care and a comprehensive approach. Such care requires stakeholder alignment across multiple specialties and care settings.

An Anatomy-Informed, Novel Technique for S1 Dorsal Root Ganglion Stimulation Lead Placement.

Objective: A heightened and organized understanding of sacral anatomy could potentially lead to a more effective and safe method of dorsal root ganglion stimulation (DRG-S) lead placement. The aim of this technical note is to describe a standardized access method for S1 DRG-S lead placement.

Design: Technical note.

A multisociety organizational consensus process to define guiding principles for acute perioperative pain management.

The US Health and Human Services Pain Management Best Practices Inter-Agency Task Force initiated a public-private partnership which led to the publication of its report in 2019. The report emphasized the need for individualized, multimodal, and multidisciplinary approaches to pain management that decrease the over-reliance on opioids, increase access to care, and promote widespread education on pain and substance use disorders. The Task Force specifically called on specialty organizations to work together to develop evidence-based guidelines.

A paramedian approach for dorsal root ganglion stimulation placement developed to limit lead migration and fracture.

Introduction: Dorsal root ganglion stimulation (DRG-S), has demonstrated superiority in the treatment of complex regional pain syndrome and causalgia. Lead migration and fracture impact DRG-S therapeutic stability. Lead anchoring reduces DRG-S lead migration without increasing lead fracture.

Pharmacogenomic considerations for medications in the perioperative setting.

Several high-profile examples of adverse outcomes from medications used in the perioperative setting are well known (e.g., malignant hyperthermia, prolonged apnea, respiratory depression, inadequate analgesia), leading to an increased understanding of genetic susceptibilities underlying these risks.

The impact of psychiatric comorbidities on patient-reported surgical outcomes in adults treated for the median arcuate ligament syndrome.

Objective: Median arcuate ligament syndrome (MALS) is an often overlooked, surgically correctable condition that mimics functional chronic abdominal pain. Patient-reported surgical outcomes are unpredictable in MALS. The objective of this study was to define the psychiatric comorbidities in a cohort of adults undergoing surgery for MALS and to determine whether these comorbidities are predictive of patient-reported quality of life (QOL) outcomes.

Postoperative continuous adductor canal block for total knee arthroplasty improves pain and functional recovery: A randomized controlled clinical trial.

Study Objective: Investigate the use of a postoperative continuous adductor canal block (cACB) after epidural analgesia to decreases opioid consumption and improve visual analog scale (VAS) scores compared to a sham catheter.

Design: Double-blinded randomized placebo-controlled trial.

Setting: Inpatient setting in tertiary care teaching hospital with outpatient follow-up.

Labor Epidural Intolerance Due to a Congenitally Narrowed Spinal Canal.

Reports exist of severe upper back pain of unknown etiology after administration of large volumes into the epidural space. We present a case of an otherwise healthy parturient who developed severe upper back and neck pain after receiving only a small volume of epidural medication. Magnetic resonance imaging revealed a congenitally narrowed spinal canal because of short pedicle syndrome.

Local anesthetic systemic toxicity.

Local anesthetic systemic toxicity (LAST) is a rare yet devastating complication from the administration of local anesthesia. The ability to recognize and treat LAST is critical for clinicians who administer these drugs. The authors reviewed the literature on the mechanism, treatment, and prevention of LAST, with the goal of proposing a practical method for its management.

Acute pain management.

This article updates acute pain management in ambulatory surgery and proposes a practical three-step approach for reducing the impact and incidence of uncontrolled surgical pain. By identifying at-risk patients, implementing multimodal analgesia, and intervening promptly with rescue therapies, the anesthesiologist may improve outcomes, reduce cost, and optimize the patient's experience and quality of recovery.

Preparing for the physician payment sunshine act.

In March of 2010, President Barack Obama signed into law the Patient Protection and Affordable Care Act, ushering in an era of health care reform. Section 6002 of the bill, the Physician Payment Sunshine Act, requires manufacturers of drugs, devices, biological therapeutics, and medical supplies to disclose to the Centers for Medicare and Medicaid Services any payments or transfers of value to physicians. These reports are not meant to prohibit relationships between physicians and industry, but rather to generate a searchable public database illustrating the purpose of the payment, the entities involved, and the timing of each occurrence.
