In the present review, the analgesic effects of lidocaine in acute or chronic painful conditions in the emergency department are discussed. Lidocaine, as a medium-acting local anesthetic with short onset time, is well-recognized, not only as a valuable medication for numerous neuropathic pain conditions, but also for the management of both acute and chronic pain. ⋯ The antinociceptive properties of lidocaine are derived from multifaceted mechanisms, turning it into a medication that is safe to administer via different routes which makes it available for use in a variety of medical conditions.

Comparative StudyRespiratory Diseases in Pediatric Triage: A Comparison Between a General Emergency Department and a Pediatric Emergency Department.
In this study, the authors have compared data concerning the pediatric triage that is carried out in 2 large emergency departments (EDs) in Rome, one located in a university pediatric clinic with qualified staff and the other one in a general hospital with a high flow of users and pediatric admissions. ⋯ In the light of what we pointed out, it is necessary to implement the educational and informative quality of the triage operators and educators, planning periodical triage training courses to reduce errors. Particular emphasis must be placed on providing pediatric continuing education for nurses practicing in general ED.

Scaphoid fractures are the most common carpal fracture, representing 70% of carpal bone fractures. The diagnostic accuracy of physical examination findings and emergency medicine (EM) imaging studies for scaphoid fracture has not been previously described in the EM literature. Plain x-rays are insufficient to rule out scaphoid fractures in a patient with a suggestive mechanism and radial-sided tenderness on physical examination. This study was a meta-analysis of historical features, physical examination findings, and imaging studies for scaphoid fractures not visualized on plain x-ray in adult emergency department (ED) patients, specifically to address which types of imaging tests should be recommended in patients with persistent concern for acute fracture after ED discharge. ⋯ Except for the absence of snuffbox tenderness, which can significantly reduce the probability of scaphoid fracture, history and physical examination alone are inadequate to rule in or rule out scaphoid fracture. MRI is the most accurate imaging test to diagnose scaphoid fractures in ED patients with no evidence of fracture on initial x-rays. If MRI is unavailable, CT is adequate to rule in scaphoid fractures, but inadequate for ruling out scaphoid fractures.

The Microcirculation Is Preserved in Emergency Department Low-acuity Sepsis Patients Without Hypotension.
Microcirculatory dysfunction plays an important role in sepsis pathophysiology. Previous studies using sidestream dark-field (SDF) imaging have demonstrated microcirculatory flow abnormalities in patients with septic shock; however, the microcirculation is relatively unstudied in lower-acuity sepsis patients. The hypothesis was that patients with sepsis, but without hypotension, will demonstrate signs of flow abnormalities compared to noninfected control patients. ⋯ Measureable microcirculatory flow abnormalities were not observed in patients with early sepsis in the absence of hypotension. However, microcirculatory abnormalities were correlated with elevated serum lactate in normotensive sepsis patients, supporting the notion that impaired microcirculatory flow is coupled with cellular distress.

ABSTRACTObjectives:Unenhanced computed tomography (CT) has become a standard imaging technique for uncomplicated renal colic in many countries. The appropriate timing of CT imaging has not been established, and guidelines recommend that this imaging be performed between 1 and 7 days of presentation. The primary objective of this study was to determine the prevalence of alternative diagnosis identified with low-dose unenhanced CT in the emergency department (ED) in patients with suspected uncomplicated renal colic. ⋯ Low-dose unenhanced CT in the ED detects alternative diagnoses in 6% (95% CI 3-10) of patients with suspected uncomplicated renal colic, half of whom are subsequently hospitalized. Our prospective findings, which were similar to those reported in retrospective studies, are a potential argument for a systematic approach to ED imaging in suspected renal colic. Future research involving intervention and control groups would be helpful.
