von Foerster N, Radomski MA, Martin-Gill C. Prehospital Ultrasound: A Narrative Review. PREHOSP EMERG CARE 2022; 28:1-13. [PMID: 36194192 DOI: 10.1080/10903127.2022.2132332] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Revised: 09/30/2022] [Accepted: 09/30/2022] [Indexed: 10/31/2022]
Abstract
Background: Point-of-care ultrasound is rapidly becoming more prevalent in the prehospital environment. Though considered a relatively new intervention in this setting, there is growing literature that aims to explore the use of prehospital ultrasound by EMS personnel.Methods: To better understand and report the state of the science on prehospital ultrasound, we conducted a narrative review of the literature.Results: Following a keyword search of MEDLINE in Ovid from inception to August 2, 2022, 2,564 records were identified and screened. Based on review of abstracts and full texts, with addition of seven articles via bibliography review, 193 records were included. Many included studies detail usage in air medical and other critical care transport environments. Clinicians performing prehospital ultrasound are often physicians or other advanced practice personnel who have previous ultrasound experience, which facilitates implementation in the prehospital setting. Emerging literature details training programs for prehospital personnel who are novices to ultrasound, and implementation for some study types appears feasible without prior experience. Unique use scenarios that show promise include during critical care transport, for triage in austere settings, and for thoracic evaluation of patients at risk of life-threatening pathology.Conclusion: There is a growing mostly observational body of literature describing the use of ultrasound by prehospital personnel. Prehospital ultrasound has demonstrated feasibility for specific conditions, yet interventional studies evaluating benefit to patient outcomes are absent.

Abstract
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. However, miniaturization may come with consequences. The ability to accurately interpret ultrasound on a smaller screen is unknown. This pilot study aims to assess how screen size affects the ability of emergency medicine clinicians to accurately interpret US videos. METHODS This pilot study enrolled a prospective convenience sample of emergency medicine physicians. Participants completed a survey and were randomized to interpret US videos starting with either a phone-sized screen or a laptop-sized screen, switching to the other device at the halfway point. 50 unique US videos depicting right upper quadrant (RUQ) views of the Focused Assessment with Sonography in Trauma (FAST) examination were chosen for inclusion in the study. There were 25 US videos per device. All of the images were previously obtained on a cart-based machine (Mindray M9) and preselected by the study authors. Participants answered "Yes" or "No" in response to whether they identified free fluid. The time that each participant took to interpret each video was also recorded. Following the assessment, participants completed a post-interpretation survey. The goal of the pilot was to determine the accuracy of image interpretation on a small screen as compared to a laptop-sized screen. Statistical analyses were performed using MATLAB (The MathWorks, Inc., Natick, MA). Nonparametric statistical tests were utilized to compare subgroups, with a Wilcoxon signed rank test used for paired data and a Wilcoxon rank sum test for unpaired data. RESULTS 52 emergency medicine physicians were enrolled in the study. The median accuracy of US interpretation for phone versus laptop image screen was 88.0% and 87.6% (p = 0.67). The mean time to interpret with phone versus laptop screen was 293 and 290 s (p = 0.66). CONCLUSIONS The study found no statistically significant difference in the accuracy of US interpretation nor time spent interpreting when the pre-selected RUQ videos generated on a cart-based ultrasound machine were reviewed on a phone-sized versus a laptop-sized screen. This pilot study suggests that the accuracy of US interpretation may not be dependent upon the size of the screen utilized.

Abstract
Point-of-care ultrasound (POCUS) is currently implemented in various medical fields by clinicians for the bedside examination of patients. Evidence supports the fact that adding an ultrasound technology in daily practice (hand-held ultrasound device), called by some 'stethoscope of the future', improves patient care and allows an earlier diagnosis in a hospital setting. In this article, we reviewed the historical evolution of the use of ultrasound in medicine and the possibilities of using POCUS for hospitalists and general internists based on the existing scientific literature.

Abstract
Ultrasound is increasingly used in daily clinical practice to improve the efficiency of the clinical examination. In this article, we reviewed its various possible uses in the field of diabetology. The ultrasonic evaluation of the carotid arteries (plaques and intima media thickness) allows improving the assessment of the cardiovascular risk. Steatosis can be detected relatively easily on liver ultrasound. Ultrasound also allows a more sensitive detection of lipohypertrophy resulting in glycemic fluctuations and thus increasing the risk of hypoglycemia than the clinical examination. Finally, muscle ultrasound appears to be a promising tool to assess the nutritional status and its consequences (e.g., falls).

Abstract
Abstract
Introduction
Ultrasound is now recognized as a key tool in the practice of medicine in isolated situations. This study aims to evaluate the impact of transthoracic echocardiography (TTE) in a military mission when performed by a trained military practitioner (MP).
Materials and Methods
We conducted a 2-month retrospective observational study on the use of TTE in a French medical complex in Mali with a mission that included providing a medical aid to the population. All patients were included. Every ultrasound performed by the MP was listed, and the epidemiologic data, indication for the exam and results were collected for each TTE.
Results
A total of 349 patients were included, 16 were war-wounded patients and 333 came for a general medical consultation. In all, 153 ultrasounds were performed, including 48 TTEs. Sixteen TTEs were performed to evaluate injuries in war-wounded patients. During the 333 medical consultations, 32 TTEs were realized. The indications were dyspnoea (10), heart murmur (7), acute chest pain (5) and assessment of heart disease (10). TTE permitted a direct positive diagnosis for 18 patients: 7 with acute heart failure and 11 with morphologic problems. The normality of the exam was a supplementary argument to exclude a cardiac implication for eight patients.
Conclusions
TTE can provide important information with a direct impact on the management of patients. Faced with cardiac emergencies, an adapted training can be proposed for the MP. Thereby, the transfer of conventional cardiac views could facilitate the advice of a cardiologist.

Not Just Hocus POCUS: Implementation of a Point of Care Ultrasound Curriculum for Internal Medicine Trainees at a Large Residency Program. Mil Med 2020; 184:901-906. [PMID: 31125075 DOI: 10.1093/milmed/usz124] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2019] [Revised: 04/09/2019] [Accepted: 05/04/2019] [Indexed: 01/30/2023] Open
Abstract
INTRODUCTION In 2018, the American College of Physicians formally acknowledged the importance of Point of Care Ultrasound (POCUS) to the practice of internal medicine (IM). For the military internist, POCUS training is critical for care of the trauma patient in austere environments, mass casualty events and natural disasters. While emergency medicine and critical care training programs have adopted POCUS education, few IM programs have integrated POCUS into their core curricula. We designed and implemented an iterative POCUS curriculum for trainees at a large military IM residency program over a two-year period. METHODS In collaboration with our critical care and simulation departments, we developed a pilot curriculum consisting of five, 60-minute courses offered on a voluntary basis at monthly intervals throughout 2017. Based on the pilot's success we incorporated a POCUS curriculum into the core academics received by all IM trainees during the 2017-2018 academic year. Trainees attended seven, 3-hour sessions during their scheduled academic time taught by subspecialists with POCUS expertise in an on-site simulation center. Baseline surveys and knowledge assessment examinations were administered during orientation and repeated at the end of the academic year. Comparison of results before and after the POCUS curriculum was the primary outcome evaluated. RESULTS Intervention #1: Pilot, 2016-2017 Academic Year45 trainees attended at least one course with an average of 1.8 sessions per trainee. Baseline survey data showed 91% of trainees believe POCUS is quite or extremely beneficial for their patients, but 73% feel slightly or not at all confident in POCUS knowledge. The pre-test mean and median scores were 71% and 77% respectively, which both increased to a post-test mean and median of 81%. Post-test mean percentage correct for trainees attending 1, 2, or 3 courses was 74%, 82%, and 91% respectively. Intervention #2: Incorporation of POCUS into Core Academics, 2017-2018 Academic YearAll 75 trainees participated in training with an average of 3.77 sessions attended per trainee. Survey analysis revealed significant improvement in confidence of performing ultrasound-guided procedures (p = 0.0139), and a 37% absolute increase in respondents who anticipate using ultrasound in their clinical practice (p = 0.0003). The mean pre-test score was 67.8% with median of 63.6% while mean and median post-test scores were 82.1% and 81.8%, with an absolute improvement of 14.3% and 18.2% respectively (p = 0.0004). CONCLUSION A structured POCUS curriculum was successfully incorporated at a large multiservice military IM residency program, with demonstrated retention of knowledge, improved confidence in performance of ultrasound guided invasive procedures, and increased interest in the use of POCUS in future clinical practice. Similar programs should be implemented across all IM programs in military graduate medical education to enhance operational readiness and battlefield care.

Abstract
INTRODUCTION The usefulness of departmental diagnostic ultrasound in the role 2 setting has not been previously evaluated. This is because role 2 hospital manning does not traditionally include a diagnostic radiologist. This study aims to evaluate the usefulness of this added capability in the deployed role 2 hospital setting. METHODS Prospective data were collected using a questionnaire alongside each scan request during the Op TRENTON 3 operational period. This included details of clinical indication and presumptive diagnosis. Scans were acquired and reported as part of routine care. The postscan clinical diagnosis and effect on management plan were determined by the treating clinician and recorded on the questionnaire. Point-of-care and focused assessment with sonography in trauma scans were excluded, as were ultrasound-guided interventional procedures. RESULTS 41 diagnostic departmental scans were included over the six-month period. 68% (28/41) of the scans increased clinical confidence in the management plan, while 29% (12/41) led to an alteration in the management plan. Only one examination (3%) was deemed to have had no clinical impact. Overall, the musculoskeletal scans had the greatest impact on patient management. CONCLUSIONS Constraints of manoeuvrability at role 2 currently preclude the availability of body CT and shift the demand for diagnostic soft tissue imaging to ultrasound. This capability is only possible with the deployment of suitably trained individuals. This study highlights the utility of this capability at role 2. Musculoskeletal ultrasound skills were of particular value, and training should be encouraged among physiotherapists and radiographers in lieu of, where necessary, a suitably trained deployable radiologist.

Abstract
AbstractIntroductionPoint-of-Care Ultrasound (POCUS) has become an important diagnostic tool for hospital-based clinicians. This study assesses the role of POCUS at Pemberton Music Festival 2016 (Pemberton, British Columbia [BC], Canada), a remote mass gathering where physicians face limited resources, complex disposition decisions, and a dynamic clinical environment.ObjectivesThis study prospectively evaluated the impact of POCUS on patient diagnosis, management, and disposition based on the self-report of the study physicians. The authors hypothesized that having ultrasound available for use would aid in diagnostic and management decisions and would reduce the need to transfer patients off-site to other health care facilities, reducing impact on the acute health services in the host community.MethodsA handheld ultrasound was available for use by physicians in the main medical tent. All participating physicians self-reported their training and comfort using POCUS. After each POCUS scan, physicians completed a survey and recorded the indication for use, scans performed, and impact on patient diagnosis, management, and disposition.ResultsIn total, POCUS was used on 28 of the 686 patients treated in the main medical tent; POCUS was reported to narrow the differential diagnosis in 64% of cases and altered the working diagnosis in 21% of cases. Its use changed the management plan in 39% of patients. Its use was reported to reduce the burden on broader health care resource utilization in 46% of cases and prevented ambulance transport off-site in 32% of cases (nine cases in total). This corresponded to an absolute risk reduction of 1.3% for the percentage of patients transferred to hospital (PPTH; relative risk reduction of 53%).Conclusion:Physicians reported that POCUS improved the diagnosis, management, and disposition of select patients at a remote, multi-day music festival. Also, POCUS reduced ambulance transfers off-site and reduced the perceived burden on broader health care utilization.PragerR, SedgwickC, LundA, KimD, HoB, StachuraM, GutmanS.

Abstract
Chest ultrasonography (CU) is a noninvasive imaging technique able to provide an immediate diagnosis of the underlying aetiology of acute respiratory failure and traumatic chest injuries. Given the great technologies, it is now possible to perform accurate CU in remote and adverse environments including the combat field, extreme sport settings, and environmental disasters, as well as during space missions. Today, the usage of CU in the extreme emergency setting is more likely to occur, as this technique proved to be a fast diagnostic tool to assist resuscitation manoeuvres and interventional procedures in many cases. A scientific literature review is presented here. This was based on a systematic search of published literature, on the following online databases: PubMed and Scopus. The following words were used: "chest sonography," " thoracic ultrasound," and "lung sonography," in different combinations with "extreme sport," "extreme environment," "wilderness," "catastrophe," and "extreme conditions." This manuscript reports the most relevant usages of CU in the extreme setting as well as technological improvements and current limitations. CU application in the extreme setting is further encouraged here.

Abstract
During the past decade, ultrasound has expanded medical imaging well beyond the "traditional" radiology setting: a combination of portability, low cost, and ease of use makes ultrasound imaging an indispensable tool for radiologists as well as for other medical professionals who need to obtain imaging diagnosis or guide a therapeutic intervention quickly and efficiently. Ultrasound combines excellent ability for deep penetration into soft tissues with very good spatial resolution, with only a few exceptions (ie, those involving overlying bone or gas). Real-time imaging (up to hundreds and thousands of frames per second) enables guidance of therapeutic procedures and biopsies; characterization of the mechanical properties of the tissues greatly aids with the accuracy of the procedures. The ability of ultrasound to deposit energy locally brings about the potential for localized intervention encompassing the following: tissue ablation, enhancing penetration through the natural barriers to drug delivery in the body and triggering drug release from carrier microparticles and nanoparticles. The use of microbubble contrast agents brings the ability to monitor and quantify tissue perfusion, and microbubble targeting with ligand-decorated microbubbles brings the ability to obtain molecular biomarker information, that is, ultrasound molecular imaging. Overall, ultrasound has become the most widely used imaging modality in modern medicine; it will continue to grow and expand.

Abstract
Introduction: Australian medical ultrasound started in 1959 with the establishment of the Ultrasonics Institute. Since then the technology has advanced tremendously. We are now not only able to obtain clearer images on high specification ultrasound machines but also on pocket-sized ultrasound machines that are compact, lightweight and affordable. Method: The following descriptive review will examine the indication for use of pocket ultrasound machines in different clinical settings as well as provide evidence of its image clarity and accuracy. Potentially eligible studies were sought primarily through searches of the electronic databases PubMed, Medline (1996-Present), Embase (1996-Present) and Cochrane Library. Conclusion: Pocket ultrasound machines, with appropriate ultrasound knowledge and training, can be incorporated successfully in patient management. The addition of point-of-care ultrasound has been shown to improve management recommendations and outcomes.

Abstract
PURPOSE OF REVIEW Pain management in the trauma patient can be challenging, especially outside the operating room setting. Traditional analgesics such as opioids and NSAIDs are also problematic in trauma care. In this review, the use of regional anesthetic techniques outside the operating theatre is discussed. RECENT FINDINGS Regional anesthesia is an increasing but still underutilized clinical tool for the trauma patient outside the operating room. Regional anesthesia provides well tolerated and effective analgesia and anesthesia for many indications in the trauma setting including hip fracture, reduction of joint dislocation, wound debridement, laceration repair, and multiple rib fractures. Its use can increase safety and resource allocation in emergency departments. Performance of peripheral nerve blocks, especially with ultrasound, is amenable in various medical environments with minimal training. SUMMARY Pain is often poorly managed in the trauma patient. In addition to quality analgesia, regional anesthesia provides a variety of benefits in the trauma setting outside the traditional operating room setting. While further utilization requires increased training and structural changes, existing tools such as ultrasound are removing barriers to the widespread use of peripheral nerve block techniques across multiple disciplines.

Abstract
BACKGROUND Human activity in wilderness areas has increased globally in recent decades, leading to increased risk of injury and illness. Wilderness medicine has developed in response to both need and interest. METHODS The field of wilderness medicine encompasses many areas of interest. Some focus on special circumstances (such as avalanches) while others have a broader scope (such as trauma care). Several core areas of key interest within wilderness medicine are discussed in this study. RESULTS Wilderness medicine is characterized by remote and improvised care of patients with routine or exotic illnesses or trauma, limited resources and manpower, and delayed evacuation to definitive care. Wilderness medicine is developing rapidly and draws from the breadth of medical and surgical subspecialties as well as the technical fields of mountaineering, climbing, and diving. Research, epidemiology, and evidence-based guidelines are evolving. A hallmark of this field is injury prevention and risk mitigation. The range of topics encompasses high-altitude cerebral edema, decompression sickness, snake envenomation, lightning injury, extremity trauma, and gastroenteritis. Several professional societies, academic fellowships, and training organizations offer education and resources for laypeople and health care professionals. CONCLUSIONS THE FUTURE OF WILDERNESS MEDICINE IS UNFOLDING ON MULTIPLE FRONTS: education, research, training, technology, communications, and environment. Although wilderness medicine research is technically difficult to perform, it is essential to deepening our understanding of the contribution of specific techniques in achieving improvements in clinical outcomes.

Abstract
SUMMARY Battlefield analgesia and post-injury pain management is a high priority within the military medical community. The combined military services of the USA have developed a Pain Task Force and clinical practice guidelines to ensure that adequate analgesia is provided to our wounded soldiers as far forward as the point of injury on the battlefield. As a result of this emphasis, novel analgesic techniques and equipment have led to improved pain management. Continuous peripheral nerve blocks, intranasal ketamine, battlefield acupuncture and other adjuncts have all been utilized safely and successfully. The ability to provide rapid analgesia as early in the course of injury as possible not only helps with the immediate pain of the soldier, but potentially minimizes the risk of developing chronic postinjury pain. During the long medical evacuation system the risks of both undertreatment and overtreatment of pain are very real. Future studies and observation will help to delineate best treatment regimens and pave the way for the next generation of medical providers to positively impact a soldier’s recovery. This article is written from the perspective of the USA with a focus on the conflicts in Afghanistan (Operation Enduring Freedom) and Iraq (Operation Iraqi Freedom).
