Can Untrained Patients Perform Their Own Skin and Soft Tissue Ultrasound Examination by Teleguidance?

This pilot study aims to determine if patients untrained in performing ultrasound can self-scan to obtain images under remote clinician teleguidance during a simulated telehealth encounter. This study also seeks to describe the patients' comfort level and barriers to performing an ultrasound examination on themselves using a handheld ultrasound device. This was a single center prospective observational cohort study conducted over a 4-month period in 2021.

Ultrasound-Guided Peripheral Nerve Blocks for Shoulder Dislocation in the Emergency Department: A Systemic Review.

Background: Shoulder dislocations are among the most common orthopedic emergencies encountered in the emergency department (ED). Ultrasound-guided peripheral nerve blocks (USG-PNBs) are increasingly being used for acute pain management in the ED, but clinical evidence supporting their utility for shoulder dislocation is limited and often conflicting.

Objective: The aim of this review was to summarize and evaluate the utility of USG-PNB for analgesia during closed reduction of dislocated shoulders in the ED.

The effect of display size on ultrasound interpretation.

Objectives: Ultrasound (US) is an essential component of emergency department patient care. US machines have become smaller and more affordable. Handheld ultrasound (HUS) machines are even more portable and easy to use at the patient's bedside.

Konnyaku jelly: A quick preparation and cost effective ultrasound-guided IV phantom model.

Clinicians commonly place ultrasound-guided intravenous catheters in peripheral veins for the diagnostic and therapeutic treatments of patients. This procedural skill requires practice and static phantom models are a commonly used education tool. Several commercial models that simulate blood vessels within tissue are available; however, they can be expensive.

Medical students are accurate in interpreting the presence of pathologic interstitial edema on focused lung ultrasound compared to expert reviewers.

Background: Over the past two decades, studies have demonstrated that lung ultrasound is useful in diagnosing alveolar interstitial syndrome, which is seen in patients with decompensated congestive heart failure (CHF).

Methods: We studied medical students performing lung ultrasound on patients admitted to the hospital with a presumed diagnosis of decompensated CHF in a prospective convenience observation study. Two ultrasound fellowship-trained emergency medicine attendings independently reviewed the lung ultrasounds at a later date, blinded to the students' interpretation and other clinical information, to confirm ultrasound findings and assess for inter-rater reliability of the lung ultrasound using intraclass correlation coefficients (ICCs).

E-cigarette or vaping product use-associated lung injury (EVALI) characterized by pulmonary ultrasound.

Pulmonary ultrasound is a useful tool in the diagnosis and resuscitation of emergency department (ED) patients with dyspnea. We present the case of a patient who was diagnosed with E-cigarette or vaping product use-associated lung injury (EVALI) using pulmonary ultrasound. Many of these cases are diagnosed using x-ray, computerized tomography, or bronchoscopy and to our knowledge this is the first published case that demonstrates utility of ultrasound in diagnosing EVALI.

A comparison of homemade vascular access ultrasound phantom models for peripheral intravenous catheter insertion.

Background: Ultrasound (U/S) guided peripheral IV catheter (PIV) placement is often needed after unsuccessful traditional IV attempts. Commercial U/S PIV training phantoms are expensive and difficult to alter. Non-commercial phantoms have been described; however, there has been no comparison of these models.

Use of the color Doppler twinkle artifact for teaching ultrasound guided peripheral vascular access.

Background: The optimal method for teaching ultrasound guided peripheral IV (USGPIV) insertion is unknown. Poor needle tip visualization has been cited for USGPIV failure. Twinkle artifact (TA), visualized with color Doppler, is used in other clinical settings.

Cross-specialty Collaboration and Education for Neurosurgical Trainees: Teaching Arterial Line Placement Under Ultrasound Guidance.

Introduction Interprofessional collaboration (IPC) increases patient safety. IPC is learned through task-based exercises, such as ultrasound (U/S)-guided arterial lines. We set out to teach U/S-guided arterial lines as a framework to improve IPC between emergency medicine and neurosurgery residents.

Unorthodox Use of Point-of-care Ultrasound to Evaluate Seizures.

It can be difficult to distinguish between syncope and seizure. Some stigmata of seizure include post-ictal period, tongue-biting or incontinence. A less common finding after a seizure is a posterior shoulder dislocation.

A Three-dimensional Printed Low-cost Anterior Shoulder Dislocation Model for Ultrasound-guided Injection Training.

Anterior shoulder dislocations are the most common, large joint dislocations that present to the emergency department (ED). Numerous studies support the use of intraarticular local anesthetic injections for the safe, effective, and time-saving reduction of these dislocations. Simulation training is an alternative and effective method for training compared to bedside learning.

Ultrasonography in Undergraduate Medical Education: A Systematic Review.

Objectives: The purpose of this study was to conduct a systematic review of the evidence of educational outcomes associated with teaching ultrasonography (US) to medical students.

Methods: A review of databases through 2016 was conducted for research studies that reported data on teaching US to medical students. Each title and abstract were reviewed by teams of 2 independent abstractors to determine whether the article would be ordered for full-text review and subsequently by 2 independent authors for inclusion.

Transthoracic Echocardiography for Diagnosing Pulmonary Embolism: A Systematic Review and Meta-Analysis.

Objective: Pulmonary embolism (PE) is a common diagnosis with significant mortality if not appropriately treated. The use of transthoracic echocardiography in patients with PE is common; however, its diagnostic capabilities in this use are unclear. With the increased use of ultrasonography in medical settings, it is important to understand the strengths and limitations of echocardiography for the diagnosis of PE.

Accuracy of Point-of-care Ultrasonography for Diagnosing Acute Appendicitis: A Systematic Review and Meta-analysis.

Background: The use of ultrasonography (US) to diagnose appendicitis is well established. More recently, point-of-care ultrasonography (POCUS) has also been studied for the diagnosis of appendicitis, which may also prove a valuable diagnostic tool. The purpose of this study was through systematic review and meta-analysis to identify the test characteristics of POCUS, specifically US performed by a nonradiologist physician, in accurately diagnosing acute appendicitis in patients of any age.

A randomized study of training with large versus small vessel size on successful ultrasound-guided peripheral venous access.

Purpose: Our objective was to investigate whether training on phantoms with smaller or larger vessels would improve success rate in novice medical students learning this skill.

Methods: Medical students who participated in a voluntary, extracurricular ultrasound training day were asked to participate in the study as part of their procedural training. They were given a standardized education and demonstration of how to use ultrasound to place a peripheral intravenous (IV) catheter.

Ultrasound measurement of inferior vena cava collapse predicts propofol-induced hypotension.

Study Objectives: Hypotension is a common side effect of propofol, but there are no reliable methods to determine which patients are at risk for significant propofol-induced hypotension (PIH). Ultrasound has been used to estimate volume status by visualization of inferior vena cava (IVC) collapse. This study explores whether IVC assessment by ultrasound can assist in predicting which patients may experience significant hypotension.
