Randomized Controlled TrialGenicular nerve block in rheumatoid arthritis: a randomized clinical trial.
This study highlights the effect of a genicular nerve block (GNB) on pain, function, and inflammation outcome measures in rheumatoid arthritis (RA) knees. ⋯ GNB is a new promising local therapy for RA to control pain, improve function, and alleviate inflammation of the knee joint. Although it has a relatively short-term effect, yet it has outperformed the steroid effect. Key Points • Knee monoarthritis treatment in rheumatoid arthritis is always challenging • GNB has been approved for the treatment of pain in knee osteoarthritis • GNB in this study was able to control active knee arthritis and this effect persisted longer thane intra-articular steroid injection.

Paravertebral pain catheters have been shown to be equally effective as epidural pain catheters for postoperative analgesia after thoracic surgery with the possible additional benefit of less hemodynamic effect. However, a methodology for verifying correct paravertebral catheter placement has not been tested or objectively confirmed in previous studies. The aim of the current study was to describe a technique to confirm the correct position of a paravertebral pain catheter using a contrast-enhanced paravertebrogram. ⋯ This proof of concept study demonstrated that a contrast-enhanced paravertebrogram could be used in conjunction with standard postoperative chest radiography to add valuable information for the assessment of paravertebral catheter placement. This technique has the potential to increase the accuracy and efficiency of postoperative analgesia, and to set a quality standard for future studies of paravertebral pain catheters.

Acute pain is one of the most common complaints encountered in the emergency department (ED). Single-injection peripheral nerve blocks are a safe and effective pain management tool when performed in the ED. Dexamethasone has been explored as an adjuvant to prolong duration of analgesia from peripheral nerve blocks in peri- and postoperative settings; however, data surrounding the use of dexamethasone for ED-performed nerve blocks are lacking. ⋯ In this case series we discuss our experience with adjunctive perineural dexamethasone in ED-performed regional anesthesia. Why Should an Emergency Physician be Aware of This?: Nerve blocks performed with adjuvant perineural dexamethasone may be a safe additive to provide analgesia beyond the expected half-life of local anesthetic alone. Prospective studies exploring the role of adjuvant perineural dexamethasone in ED-performed nerve blocks are needed. © 2021 Elsevier Inc.

Pain management in shoulder arthroplasty: a systematic review and network meta-analysis of randomized controlled trials.
Postoperative pain management after total shoulder arthroplasty (TSA) can be challenging. Given the variety of pain management options available, the purpose of this investigation was to systematically review the literature for randomized controlled trials reporting on pain control after shoulder arthroplasty. We sought to determine which modalities are most effective in managing postoperative pain and reducing postoperative opioid use. ⋯ Interscalene blocks are superior to local injections alone at managing pain after TSA. Single-shot interscalene blocks are optimal for reducing early postoperative pain (< 24 hours), whereas pain at 24-48 hours after surgery may be best managed with cISBs or a combination of an ssISB with a local LB injection.

Ultrasound-guided nerve blocks have revolutionized the way we provide regional anesthesia. By providing effective perioperative pain control, regional anesthesia reduces opioid consumption, decreases length of stay, and increases patient/parental satisfaction. ⋯ They include failure to confirm intended block site, failure to optimize ultrasound images and identify artifacts, failure to recognize when regional anesthesia is an acceptable option, failure to implement alternative imaging techniques when anatomy is challenging, and failure to recognize disease states with abnormal anatomy that may require alternative blocks. These issues are easily addressed if the pediatric regionalist is cognizant of the appropriate ways to mitigate them, and, as such, we review strategies to avoid them.
