Despite its popularity, ultrasound (US)-guided regional anesthesiology is associated with significant limitations. The latter can be attributed to either the US machine (ie, decreased ability to insonate deep neural structures, as well as the thoracic spine) or the operator. Shortcomings associated with the operator can be explained by errors in perception (ie, ambiguous criteria for needle/catheter tip-to-nerve proximity and subparaneural local anesthetic injection) or interpretation. Perhaps the greatest confusion afflicting US-guided regional anesthesiology originates from an intellectual misconception pertaining to its application...

OBJECTIVES: Objective measures are needed to guide the novice's pathway to expertise. Within and outside medicine, eye tracking has been used for both training and assessment. We designed this study to test the hypothesis that eye tracking may differentiate novices from experts in static image interpretation for ultrasound (US)-guided regional anesthesia. METHODS: We recruited novice anesthesiology residents and regional anesthesiology experts. Participants wore eye-tracking glasses, were shown 5 sonograms of US-guided regional anesthesia, and were asked a series of anatomy-based questions related to each image while their eye movements were recorded...

BACKGROUND: Current evidence supports the utility of simulation training for bedside procedures such as ultrasound-guided jugular central venous catheter (CVC) insertion. However, a standardized methodology to teach procedural skills has not been determined yet. The aim of this study was to evaluate the effectiveness of a simulation-based training program for improving novice technical performance during ultrasound-guided internal jugular CVC placement. METHODS: Postgraduate year 1 (PGY-1) residents from anesthesiology, emergency medicine, cardiology, ICU, and nephrology specialties were trained in four deliberate practice sessions...

PURPOSE: Histological confirmation of endometrial cancer by dilatation/curettage (D/C) in women with postmenopausal bleeding (PMB) can be challenging due to anesthesiological and/or surgical risks. Thus, less invasive methods for diagnostics are required to identify patients with minimal risk for endometrial cancer (EC) to avoid unnecessary surgical intervention. The objective of this single-center cohort study was to assess the diagnostic validity of transvaginal ultrasound (TVUS) measurements of endometrial thickness (ET) in patients with PMB for the detection of EC...

Visualization of the catheter during ultrasound-guided continuous nerve block performance may be difficult but is an essential skill for regional anesthesiologists. The objective of this in vitro study was to evaluate 2 newer catheters designed for enhanced echogenicity and compare them to a widely used catheter not purposely designed for ultrasound guidance. Outcomes were the numbers of first-place rankings among all 3 catheters and scores on individual echogenicity criteria as assessed by 2 blinded reviewers...

BACKGROUND: The advent of portable ultrasound machines in recent years has led to greater availability of focused cardiac ultrasound (FoCUS) in the perioperative and critical care setting. To our knowledge, its use in the perioperative setting among anesthesiologists remains undefined. We sought to assess the use of FoCUS by members of the Society of Cardiovascular Anesthesiologists (SCA) in clinical practice, to identify variations in its application, to outline limits to its use, and to understand the level of training of physicians using this technology...

BACKGROUND: Lung ultrasound (LUS) is a point-of-care technique which can quickly identify or rule out pathological findings. To date, it is unclear if knowledge about the use of LUS is readily available. OBJECTIVES: We aimed to identify how much knowledge about the use of LUS is present, if there is a need for teaching in LUS, as well as the preferred teaching method in LUS. MATERIALS AND METHODS: A total of 54 participants from two university departments of anesthesiology were randomized into the groups Online, Classroom, and Control...

BACKGROUND: Transesophageal echocardiography (TEE) is a valuable monitor for patients undergoing cardiac and noncardiac surgery as it allows for evaluation of cardiovascular compromise in the perioperative period. It is challenging for anesthesiology residents and medical students to learn to use and interpret TEE in the clinical environment. A critical component of learning to use and interpret TEE is a strong grasp of normal cardiovascular ultrasound anatomy. METHODS: Fifteen fourth-year medical students and 15 post-graduate year (PGY) 1 and 2 anesthesiology residents without prior training in cardiac anesthesia or TEE viewed normal cardiovascular anatomy TEE video clips; participants were randomized to learning cardiac anatomy in generative retrieval (GR) and standard practice (SP) groups...

BACKGROUND: Ethiopia has a significant paucity of available health-care workers. Despite the increasing number of medical schools, there are not enough physician instructors. Furthermore, availability and standardization of postgraduate training are lacking. Modalities of e-learning have been shown to be successful when used to impart medical education in other resource-limited countries. The Emory University and Addis Ababa University (AAU) Departments of Anesthesiology have formed a collaboration with the intent of improving the AAU Anesthesiology residency program, one of two postgraduate training programs for anesthesiology in Ethiopia...

We deal with an important problem in the field of anesthesiology known as automatic segmentation of nerve structures depicted in ultrasound images. This is important to aid the experts in anesthesiology, in order to carry out Peripheral Nerve Blocking (PNB). Ultrasound imaging has gained recent interest for performing PNB procedures since it offers a non-invasive visualization of the nerve and the anatomical structures around it. However, the location of these nerves in ultrasound images is a difficult task for the specialist due to the artifacts (i...

REVIEW
Josh M Zimmerman, Bradley J Coker
The benefit of focused cardiovascular ultrasound as an adjunct to physical examination has been shown in numerous specialties and in diverse clinical settings. Although the value of these techniques to the practice of anesthesiology is substantial, they have only begun to be incorporated. This article reviews the basic techniques required to perform a bedside focused cardiovascular ultrasound (ie, FoCUS examination). This includes a discussion of patient positioning, breath control, probe position, and manipulation and was supplemented by normal and abnormal examples for review...
