A continuous peripheral nerve block (CPNB) consists of a percutaneously inserted catheter with its tip adjacent to a target nerve/plexus through which local anesthetic may be administered, providing a prolonged block that may be titrated to the desired effect. In the decades after its first report in 1946, a plethora of data relating to CPNB was published, much of which was examined in a 2011 Anesthesia & Analgesia article. The current update is an evidence-based review of the CPNB literature published in the interim...

BACKGROUND: Prostate Imaging Reporting and Data System (PI-RADS) is a globally acceptable standardization for multiparametric magnetic resonance imaging (mp-MRI) in prostate cancer (PCa) diagnosis. The American College of Radiology revised the PI-RADS to address the limitations of version 1 in December 2014. This study aimed to determine whether the PI-RADS version 2 (PI-RADS v2) scoring system improves the diagnostic accuracy of mp-MRI of the prostate compared with PI-RADS v1. METHODS: This retrospective study was approved by the institutional review board...

BACKGROUND AND OBJECTIVES: Accumulation of fluid in the lung is the most concerning sequela of volume expansion in patients with ESRD. Lung auscultation is recommended to detect and monitor pulmonary congestion, but its reliability in ESRD is unknown. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: In a subproject of the ongoing Lung Water by Ultra-Sound Guided Treatment to Prevent Death and Cardiovascular Complications in High Risk ESRD Patients with Cardiomyopathy Trial, we compared a lung ultrasound-guided ultrafiltration prescription policy versus standard care in high-risk patients on hemodialysis...

BACKGROUND: The majority of reports regarding general vascular access choices for apheresis procedures argue that peripheral venous access should be considered first. However, the clinical reality appears to be different. While some procedures mandate central vascular access (e.g., therapeutic apheresis procedures in critically ill patients) and in some cases it is the patient's preference, we propose that the majority of elective procedures can be successfully performed peripherally...

Recent progress in quantitative ultrasound has exploited the multimode waveguide response of long bones. Measurements of the guided modes, along with suitable waveguide modeling, have the potential to infer strength-related factors such as stiffness (mainly determined by cortical porosity) and cortical thickness. However, the development of such model-based approaches is challenging, in particular because of the multiparametric nature of the inverse problem. Current estimation methods in the bone field rely on a number of assumptions for pairing the incomplete experimental data with the theoretical guided modes (e...

BACKGROUND: Neonates commonly require central access, and in those with very low or extremely low birthweight this can be challenging. Described here is a technique that uses ultrasound guidance in the placement of peripherally inserted central catheters (PICC) in neonates and an analysis of outcomes. METHODS: A retrospective chart review was conducted of all patients below 1500 g that underwent placement of a peripherally inserted central catheter under ultrasound guidance between January 1, 2012, and December 31, 2014 at a single center...

PURPOSE: To assess the feasibility and safety of the 7 French (Fr) Glidesheath Slender for complex transradial (TR) percutaneous coronary interventions (PCI). BACKGROUND: The TR approach is increasingly used worldwide for coronary and peripheral vascular interventions. However, the small size of the radial artery remains an important limitation for the use of large-bore guiding catheters (>6 Fr), restricting thereby the treatment of highly complex lesions through the TR approach...

BACKGROUND: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is frequently applied to the diagnosis of central airway lesions, and endobronchial ultrasound with a guide sheath (EBUS-GS) is mainly used for the diagnosis of peripheral pulmonary lesions. However, there remains an unmet need to improve the diagnostic yields for peribronchial pulmonary lesions located along the secondary/tertiary and fourth/fifth bronchi (the "middle third zone" of the lungs), which neither EBUS-TBNA nor EBUS-GS can easily approach...

Phalanx fractures and interphalangeal joint dislocations commonly present to the emergency department. Although these orthopedic injuries are not complex, the four-point digital block used for anesthesia during the reduction can be painful. Additionally, cases requiring prolonged manipulation or consultation for adequate reduction may require repeat blockade. This case series reports four patients presenting after mechanical injuries resulting in phalanx fracture or interphalangeal joint dislocations. These patients received an ultrasound-guided peripheral nerve block of the forearm with successful subsequent reduction...

Micro- and macrovascular pathology is a frequent finding in a number of common rheumatic diseases. Secondary Raynaud's phenomenon (RP) is among the most common symptoms in systemic sclerosis and several other systemic autoimmune diseases including a broad differential diagnosis. It should be also differential from other peripheral vascular syndromes such as embolism, thrombosis, etc., some of which lead to clinical manifestation of the blue toe syndrome. The current review discusses the instrumental methods for vascular assessments...

PURPOSE: Limited data exist regarding the role of perineural blockade of the distal median, ulnar, and radial nerves as a primary anesthetic in patients undergoing hand surgery. We conducted a prospective and randomized pilot study to compare these techniques to brachial plexus blocks as a primary anesthetic in this patient population. METHODS: Sixty patients scheduled for hand surgery were randomized to receive either an ultrasound-guided supraclavicular, infraclavicular, or axillary nerve block (brachial plexus blocks) or ultrasound-guided median, ulnar, and radial nerve blocks performed at the level of the mid to proximal forearm (forearm blocks)...

INTRODUCTION: Peripheral vascular access is vital for treatment and diagnostics of hospitalized patients. Ultrasound-guided vascular access (UGVA) is superior to the landmark technique. To ensure competence-based education, an assessment tool of UGVA competence is needed. We aimed to develop a global rating scale (RS) for assessment of UGVA competence based on opinions on the content from ultrasound experts in a modified Delphi consensus study. METHODS: We included experts from anesthesiology, emergency medicine and radiology across university hospitals in Denmark...
