BACKGROUND: Ultrasound-guided regional anesthesia (UGRA) is increasingly used by emergency physicians to provide safe and effective pain relief for patients. However, one of the factors limiting its widespread use is the lack of realistic models available for learners to train on. There are currently no inexpensive nerve block models available that are injectable and that closely mimic nerves, fascial planes, muscles, and other landmarks. Our aim is to create inexpensive, injectable nerve block models that can be used as effective medical training tools for UGRA...

OBJECTIVE: To determine if an ultrasound-guided femoral nerve block (FNB) is superior to an ultrasound-guided fascia iliaca compartment block (FICB) in providing pain relief to patients with a neck of femur or proximal femoral fracture. METHODS: A double-blind randomised controlled trial was conducted. All participants received two blocks, one active and one placebo. An active FICB was administered to 52 participants and 48 participants received an active FNB. RESULTS: Analysis was completed on data collected from 100 participants...

Real-time ultrasound guidance for any intervention relies on visualization of needle advancement towards a target. Unfortunately, correct identification of the needle tip is not straightforward, as artifacts always distort the image. The ultrasonic appearance of the needle is often degraded by reverberation, comet tail, side-lobe, beam-width, or bayonet artifacts, which can easily confuse an unprepared operator. Furthermore, the typical needle image, that is, a dot or a straight line (out-of-plane and in-plane approaches, respectively), is also a result of artifacts that hide the real dimensions of the needle...

INTRODUCTION: The anterolateral abdominal wall is innervated by the T7 to L1 anterior rami, whose nerves travel in the fascial plane between the internal oblique and transversus abdominus muscles, known as the transversus abdominus plane (TAP). Ultrasound-guided techniques of regional anesthesia that target the TAP are increasingly relied upon by anesthesiologists for pain management related to major abdominal and gynecologic surgeries. Our objective was to explore the potential utility of these techniques to provide anesthesia for abdominal wall procedures in the emergency department (ED)...

OBJECTIVES: To determine whether the line-of-sight approach improved the performance time and accuracy of ultrasound (US)-guided needle placement targeting the subdeltoid bursa in a cadaver among novice operators compared to the side approach. A secondary objective was to determine whether participants thought the APPLES (angle, position, perpendicular, line up, entry, sweep) mnemonic was a helpful guide for performing the procedure. METHODS: Medical students and residents were randomized into either a line-of-sight or side approach group and then crossed over to the other group...

The ultrasound-guided superficial cervical plexus (SCP) block may be useful for providers in emergency care settings who care for patients with injuries to the ear, neck, and clavicular region, including clavicle fractures and acromioclavicular dislocations. The SCP originates from the anterior rami of the C1-C4 spinal nerves and gives rise to 4 terminal branches--greater auricular, lesser occipital, transverse cervical, and suprascapular nerves--that provide sensory innervation to the skin and superficial structures of the anterolateral neck and sections of the ear and shoulder...

Injury to the penis resulting from zipper entrapment is a painful condition that presents a unique anesthetic challenge to the emergency physician and may even require procedural sedation for removal. In this case report, we describe successful removal of zipper entrapment from the penis of a 34-year-old patient after the application of an ultrasound-guided dorsal penile nerve block. We discuss the anatomy, sonographic features, and steps required for the nerve block procedure. © 2017 Wiley Periodicals, Inc...

In patients presenting with atraumatic joint pain and swelling, diagnosis is typically made by synovial fluid analysis. Management of an acute suspected hip joint arthritis can present a challenge to the emergency physician (EP). Hip joint effusions are somewhat more difficult to identify and aspirate than effusions in other joints that are commonly managed by EPs. Identification and aspiration of a hip joint effusion under ultrasound guidance is a well-established procedure in the fields of orthopedic surgery and interventional radiology...

BACKGROUND: Ultrasound is a useful adjunct to many Emergency Department (ED) procedures. Arthrocentesis is typically performed using a landmark technique but ultrasound may provide an opportunity to improve arthrocentesis performance. OBJECTIVE: To assess the success of emergency physicians performing landmark (LM) vs. ultrasound (US)-guided knee arthrocentesis techniques. METHODS: This was a prospective, randomized, controlled study of patients requiring knee arthrocentesis who presented to one urban university ED and two community EDs between June 2005 and February 2007...

BACKGROUND: Few studies were performed to compare ultrasound guided brachial plexus block with procedural sedation for reduction of shoulder dislocations in the Emergency Department (ED). This study was done to provide further evidence regarding this comparison. METHODS: This was a randomized clinical trial performed on patients presenting with anterior shoulder dislocations to the emergency department of an academic level 2 trauma center. Exclusion criteria were any contraindications to the drugs used, any patient which may not be potentially assigned into both groups because of an underlying medical condition, presence of neurovascular compromise related to the dislocation, presence of concomitant fractures, and patient refusal to participate in the study...

OBJECTIVE: To assess the role of a portable ultrasound device in the insertion of radial artery catheters. DESIGN: Prospective, randomized, comparative study. SETTING: Tertiary university hospital. PATIENTS: Elective surgery patients requiring arterial catheter insertion for intraoperative monitoring. INTERVENTIONS: A portable ultrasound device was used to visualize the radial artery at the wrist and to direct arterial catheter insertion...

BACKGROUND: Arterial cannulation for continuous blood-pressure measurement and frequent arterial-blood sampling commonly are required in critically ill patients. OBJECTIVES: To compare ultrasound (US)-guided versus traditional palpation placement of arterial lines for time to placement, number of attempts, sites used, and complications. METHODS: This was a prospective, randomized interventional study at a Level 1 academic urban emergency department with an annual census of 78,000 patients...

BACKGROUND: Ultrasound guidance commonly is used for the placement of central venous catheters (CVCs). The Agency for Healthcare Research and Quality recommends the use of ultrasound for CVC placement as one of its 11 practices to improve patient care. Despite increased access to portable ultrasound machines and comfort with ultrasound-guided CVC access, fewer clinicians are familiar with ultrasound-guided techniques of arterial catheterization. The goal of this systematic review and meta-analysis was to determine the utility of real-time two-dimensional ultrasound guidance for radial artery catheterization...

PURPOSE.: We performed an analysis of hospitalizations involving thoracentesis procedures to determine whether the use of ultrasonographic (US) guidance is associated with differences in complications or hospital costs as compared with not using US guidance. METHODS.: We used the Premier hospital database to identify patients with ICD-9 coded thoracentesis in 2008. Use of US guidance was identified using CPT-4 codes. We performed univariate and multivariable analyses of cost data and adjusted for patient demographics, hospital characteristics, patient morbidity severity, and mortality...

STUDY OBJECTIVES: The objectives of this study are as follows: (1) to determine the incidence of complications from thoracentesis performed under ultrasound guidance by interventional radiologists in a tertiary referral teaching hospital; (2) to evaluate the incidence of vasovagal events without the use of atropine prior to thoracentesis; and (3) to evaluate patient or radiographic factors that may contribute to, or be predictive of, the development of re-expansion pulmonary edema after ultrasound-guided thoracentesis...
