The suprascapular nerve (SSN) is an important nerve that contributes to shoulder joint sensation and movement. The anterior suprascapular nerve block (aSSNB) has the potential for noninferior analgesic effect compared with the interscalene block while preserving respiratory function. This study investigated the median effective volume (MEV) of 0.375% ropivacaine in aSSNB for analgesic effect among patients undergoing arthroscopic shoulder surgery. ⋯ To produce effective analgesic effect, the MEV50 is 6 mL, and the MEV95 is 13.88 mL in patients undergoing arthroscopic shoulder surgery who receive an aSSNB using 0.375% ropivacaine for analgesia.

Complex regional pain syndrome (CRPS) is an extremely painful disorder driven primarily by inflammation. ⋯ IV delivery of ExoFlo appears safe in patients with CRPS. In addition, ExoFlo exhibited efficacy in addressing CRPS symptoms. Given the lack of effective and safe treatments available to CRPS patients, these results suggest that further studies are warranted to explore and validate this potential treatment for CRPS.

Percutaneous balloon compression (PBC) has become one of the most common and effective minimally invasive treatments for trigeminal neuralgia (TN). However, the initial and long-term pain outcomes, as well as the complication rates of PBC for patients with TN with concomitant continuous pain (CCP) have yet to be specifically documented. ⋯ This is the first specifically reported experience treating TN with CCP with PBC. PBC can result in significant relief of both episodic and constant pain from TN with CCP. Patients with a longer duration of pain and prior neurodestructive procedures have a higher risk of poor outcomes. The presence of CCP is not associated with pain outcomes and should not be considered a contraindication to PBC.

Radiofrequency ablation (RFA) is a common treatment in which radiofrequency (RF) is used to heat neural tissue and reduce pain. The impact of adipose content in tissue on the lesion size may impact efficacy, and to date, there is little, if any, data comparing its influence on RFA. ⋯ Adipose tissue content was inversely related to lesion size in all samples. This factor should be considered when assessing methods of enhancing lesion size in human models.
