Intra-Articular Lidocaine versus Procedural Sedation for Shoulder Dislocation Reduction: A Randomized Trial.

Introduction: Two common ways of providing anesthesia for shoulder dislocation reductions in the emergency department (ED) are intra-articular lidocaine (IAL) injections and procedural sedation (PS). We sought to compare PS with propofol or etomidate to IAL for shoulder dislocation reductions in the ED.

Methods: This was an open-label, randomized controlled trial of patients aged 18-70 years with anterior shoulder dislocations who presented to a single ED.

A Case of Bilateral Hearing Loss.

Case Presentation: A 53-year-old male presented to the emergency department with acute onset of bilateral hearing loss as well as vertigo and severe vomiting. The Head Impulse- Nystagmus-Test of Skew exam was indicative of a central neurologic process. Computed tomography angiogram of the head and neck revealed near-total bilateral vertebral artery occlusions in the second and third segments.

Acute adrenal insufficiency after a single dose of etomidate.

Acute adrenocortical insufficiency is a critical care emergency characterized by hemodynamic instability, lethargy, and cardiovascular collapse. Acute adrenal insufficiency has many etiologies, from rapid withdrawal of exogenous glucocorticoids to adrenocortical destruction to poor adrenal reserve after administration of steroid synthesis inhibitors. Etomidate, a parenteral hypnotic agent, is a steroid synthesis inhibitor.
