BACKGROUND Lightweight portable ultrasound is widely available, especially in inaccessible geographical areas. It demonstrates effectiveness and diagnosis improvement even in field conditions but no precise information about protocols, acquisition time, image interpretation, and the relevance in changing medical conduct exists. The COVID-19 pandemic implied many severe cases and the rapid construction of field hospitals with massive general practitioner (GP) recruitment. OBJECTIVE This prospective and descriptive study aimed to evaluate the feasibility of telemedicine guidance using a standardized multi-organ sonographic assessment protocol in untrained GPs during a COVID-19 emergency in a field hospital. METHODS Eleven COVID-19 in-patients presenting life-threatening complications, attended by local staff who spontaneously requested on-time teleconsultation, were enrolled. All untrained doctors successfully positioned the transducer and obtained key images guided by a remote doctor via telemedicine, with remote interpretation of the findings. RESULTS Only four (36%) general practitioners obtained the appropriate key heart image on the left parasternal long axis window, and three (27%) had an image interpreted remotely on-time. The evaluation time ranged from seven to 42 minutes, with a mean of 22.7 + 12. CONCLUSIONS Telemedicine is effective in guiding GPs to perform portable ultrasound in life-threatening situations, showing effectiveness in conducting decisions.

Among patients presenting to the emergency department (ED) with undifferentiated hypotension, how can point-of-care ultrasound (PoCUS) help identify abdominal aortic aneurysm (AAA) as the cause of the hypotension? Many hypotensive patients in the ED are critically ill, with only minutes available to find the cause of the hypotension and treat it before the patient decompensates. While the classic description of the presentation of a ruptured AAA is of collapse with sudden onset abdominal pain and a palpable, pulsatile abdominal mass, detection of AAA by palpation is notoriously unreliable, and many patients are unaware of their underlying condition. This life-threatening situation is made even more difficult by virtue of the fact that the patient is often too unstable to travel for traditional diagnostics such as computed tomography. This article will address the use of PoCUS for the detection of AAA in the evaluation of the hypotensive patient.

A 78-year-old male with chronic kidney disease on peritoneal dialysis developed unprovoked bilateral pulmonary embolisms. He was started on IV unfractionated heparin, but shortly thereafter developed severe pain and a small firm abdominal nodule near his dialysis catheter site. The diagnosis was unknown, and the initial plan was watchful waiting, until point-of-care ultrasound (POCUS) was used. POCUS revealed an ovoid mass with hyperdensity in the gravity dependent regions with spontaneous movement. This appearance was classic for the hematocrit sign. When combined with the clinical presentation, this was concerning for a rectus sheath hematoma. An urgent CT of the abdomen confirmed this several hours later. POCUS allowed for rapid bedside diagnosis, which expedited appropriate care in a potentially life-threatening situation.

Dear sir/madam, Point of care ultrasound (POCUS) in the hands of the non-radiologist has seen a steady growth in popularity amongst emergency, intensive care and acute medical physicians. Increased accessibility to portable, purpose-built ultrasound machines has meant that clinicians often have access to a safe and non-invasive tool to enhance their management of the unwell. Focused Acute Medicine Ultrasound (FAMUS) is the point of care ultrasound curriculum created to aid the management of the acutely unwell adult patient. Following a survey of trainees and consultants, it was apparent that there was a strong desire for Acute Medics to be able to use point of care ultrasound to aid their clinical diagnostic skills. The FAMUS committee was set up to develop competencies using the evidence base available. FAMUS stands in contrast to traditional radiology training modules, which focus on carrying out comprehensive assessments of anatomy and pathology. Instead, FAMUS delivers a syndrome-based sonographic assessment with the aim of ruling out gross pathology and interrogating underlying physiology. It serves as a useful adjunct to history and clinical examination by way of providing key information quickly and non-invasively. Furthermore, it provides a feasible way to monitor response to treatment or progression of disease and thereby providing useful dynamic information quickly and safely. The accreditation in FAMUS involves the sonographic assessment of three systems: lung, abdomen and the deep veins of the lower-limb. Accrediting in each one involves theoretical learning, a formal course attendance and achieving a set number of supervised and mentored scans. As well as technical skills, the candidate must demonstrate competence in recognising key pathology and drawing appropriate conclusions about each scan, including when to refer for departmental imaging. FAMUS was met with enthusiasm by trainees and consultants in acute medicine, and its popularity rises as more courses are becoming available for accreditation paired with increasing access to portable ultrasound units. It is envisioned that this will continue to grow and formal ‘train the trainer’ courses have been held in order to increase the pool of available supervisors. Currently, FAMUS is endorsed by the Society for Acute Medicine and recognised by the AIM training committee as a specialist skill that can be undertaken during specialist training. It has been proposed that FAMUS should be considered for integration into the acute internal medicine (AIM) curriculum, which will be re-written for 2022 in line with the GMC’s revised standards for curriculum and assessment. Thus we present in this letter, a curriculum mapping exercise that utilises a ‘knowledge, skills, behaviours’ framework in order to be considered for the AIM curriculum rewrite. We believe this will provide a standard and framework to integrate focused ultrasound in AIM training programmes with the aim of ultimately incorporating FAMUS as a core skill for all AIM trainees.

Objectives: The aquarium sign is the name given to a large quantity of bubble-like echoes that suggests the presence of hepatic portal venous gas (HPVG). Few studies in the literature have addressed the relationship between the aquarium sign and HPVG. In some cases, HPVG can only be detected using ultrasonography. HPVG can be observed in a variety of conditions, including those that require emergency surgery, such as acute mesenteric ischaemia (AMI). Therefore, it is important to identify the presence of HPVG as soon as possible.  Materials and methods: We report a case of the aquarium sign, where bubble-like echoes flowed from the right atrium towards the right ventricle, which was identified using bedside cardiac ultrasonography as part of a point-of-care ultrasound test. Results: This aquarium sign finding led to the diagnosis of AMI, which was confirmed using contrast-enhanced computed tomography (CT).  Conclusion: The aquarium sign is a useful finding suggestive of HPVG and mesenteric ischaemia, which can be rapidly and easily observed using bedside cardiac ultrasonography. However, there are very few reports on the aquarium sign. The inability of other more cumbersome diagnostic imaging modalities, such as CT and magnetic resonance imaging, to detect HPVG emphasizes the utility and convenience of detecting the aquarium sign using bedside ultrasonography. This technique can lead to early detection of life-threatening diseases as well as improve the prognosis for patients. The diagnostic implications of the aquarium sign for HPVG are still unclear and require further research.

Ultrasound technology has rapidly progressed over the past decades to emerge as a portable, versatile imaging modality to complement the physical exam. It has been shown to be superior to clinical exam and equivalent to computed-tomography in detecting many life-threatening conditions, and thus is used in a variety of resuscitative settings, including the front lines of the military. A variety of imaging protocols exist for ultrasound, but in resource-deplete settings such as a disaster scenario, the focused assessment with sonography for trauma (FAST) exam is a rapid and accurate method of determining acute intraperitoneal bleeding. With improving portability, as well as the ability to transmit images to a centralized command hub, it can become a key component of the first responder’s toolkit.

Introduction: Infective endocarditis (IE) is a life-threatening condition with significant morbidity and mortality, and can require surgical repair. Case Report: A 36-year-old man presented to the emergency department for worsening dyspnea and chest pain. Point-of-care echocardiography demonstrated a mobile oscillating mass on the aortic valve with poor approximation of the valve leaflets, suggesting aortic valve insufficiency secondary to IE as the cause of acute heart failure. The patient underwent emergent aortic valve replacement within 24 hours. Discussion: While point-of-care echocardiography has been well documented in identifying tricuspid vegetations, aortic valve involvement and subsequent heart failure is less well described. Earlier recognition of aortic valve vegetations and insufficiency can expedite surgical intervention, with decreased complication rates linked to earlier antimicrobial therapy. Conclusion: This case report highlights the ability of point-of-care ultrasound to identify aortic vegetations, allowing for the earlier diagnosis and therapy.
