This study analyzed the effectiveness of suprascapular nerve block under ultrasonographic guidance in patients with perishoulder pain. Patients with perishoulder pain were enrolled in the study and were randomly divided into 2 groups. In the first group of 25 patients (12 men and 13 women), nerve block was applied under ultrasonographic guidance. Mean patient age in this group was 55.1 years. In the control group, 25 patients (11 men and 14 women) underwent nerve block without ultrasonographic guidance; mean patient age was 51.6 years. Degree of pain was assessed using a visual analog scale (VAS) and shoulder function was evaluated using the Constant shoulder score (CSS) before the nerve block, immediately following the procedure, and 1 month after the procedure. There was no statistically significant difference between the 2 groups in VAS score and CSS before the procedure (P>.05). Immediately after the procedure, both the study and control groups revealed significantly improved VAS and CSS patterns (P<.05). However, the study group showed better VAS and CSS patterns than the control group at 1-month follow-up (P<.05). No complications occurred in the study group. In the control group, there were 2 cases of arterial punctures and 3 cases of direct nerve injury with neurological deficit for 2 months. Ultrasonography-guided suprascapular nerve injection is a safe, accurate, and useful procedure compared to the blind technique.

Predictors of the Short-Term Outcomes of Guillain-Barré Syndrome: Exploring Electrodiagnostic and Clinical Features.
Brain Behav
January 2025
Department of Neurology, Chang Gung Memorial Hospital, Keelung, Taiwan.
Background And Objectives: Guillain-Barré syndrome (GBS), an acute inflammatory disorder of the peripheral nervous system, is characterized by muscle weakness and paralysis. Prompt identification of patients at a high risk of poor outcomes is crucial for timely intervention. In this study, we combined clinical data with nerve conduction study and electromyography data to identify the predictors of GBS outcomes.

Management of refractory ventricular fibrillation (VF) in patients with implantable implantable cardioverter defibrillator (ICD) presents a therapeutic challenge. We present a case of pediatric refractory ventricular tachycardia (VT)/Torsade de Pointe managed effectively with bilateral stellate ganglion block (SGB) with a long-acting local anesthetic for 18 days as a bridge to more definitive surgical management.

Department of Anesthesiology, Pain and Palliative Medicine, Radboudumc, Nijmegen, The Netherlands.
Objectives: In this study, the spread of methylene blue was compared between an ultrasound-guided Pericapsular Nerve Group (PENG) block and a double injection technique, where the approach towards the inferomedial acetabulum was added to the latter.
Methods: The two techniques were performed in 11 fresh frozen cadavers. The spread was measured after anatomical dissection in which the supplying femoral and obturator nerves were identified.
