Normology: Is it Time to Rethink Point-of-Care Ultrasound Training?

Point-of-care ultrasound (PoCUS) is increasingly being adopted by clinicians to augment their clinical examination and aid procedures. Evidence-based clinical practice guidelines now support many aspects of PoCUS practice. As a result, more and more medical schools are integrating PoCUS into their curricula, creating a significant demand for training resources. All training must ensure that trainees have the appropriate knowledge, skills and behaviour to enable the clinical integration of PoCUS. The transition from supervised to unsupervised practice is an important step in PoCUS, but should not be confused with expertise. At the start of clinical practice, confirming that something is not normal is probably enough, and trainees can subsequently improve their PoCUS diagnostic accuracy at the bedside during clinical rotations. Our hypothesis is that competency can be achieved without the need to scan patients suspected or suffering from the target pathology. This would enable most of the training to be carried out outside the clinical environment, using volunteers in planned sessions. These planned sessions will be able to accommodate a larger number of trainees and may facilitate collaboration between specialties. When patients are scanned in the clinical environment, trainees should have acquired a good level of competence beforehand. In summary, normology principles could help PoCUS trainees, at the start of their training, to acquire the knowledge, skills and behaviour necessary to achieve a level of competency allowing them to proceed to unsupervised practice. Initially confirming whether something is normal or not is enough. Nevertheless, further research should be conducted to support this concept, and its impact on PoCUS teaching in clinical practice

Conservative Treatment of Carpometacarpal Dislocation of the Three Last Fingers

Posterior carpometacarpal (CMC) dislocation is a rare condition. Treatment is usually surgical though no strict consensus can be found upon literature review. If diagnosed early and no associated fractures are found, CMC dislocation could benefit from conservative treatment comprising closed reduction and splint immobilisation. We report the case of a 26-year-old man diagnosed with a posterior dislocation of the third, fourth, and fifth CMC joints after a fall of 1.5 meters, treated by external reduction under procedural sedation and immobilisation with a cast for 6 weeks. Evolution was excellent with no relapse observed during follow-up. Our aim is to increase physician awareness of CMC dislocation so that they seek this injury in the emergency department. Unrecognised CMC dislocation can lead to neurovascular injuries as well as chronic instability and early articular degeneration

Pre-hospital management protocols and perceived difficulty in diagnosing acute heart failure

Aim To illustrate the pre-hospital management arsenals and protocols in different EMS units, and to estimate the perceived difficulty of diagnosing suspected acute heart failure (AHF) compared with other common pre-hospital conditions. Methods and results A multinational survey included 104 emergency medical service (EMS) regions from 18 countries. Diagnostic and therapeutic arsenals related to AHF management were reported for each type of EMS unit. The prevalence and contents of management protocols for common medical conditions treated pre-hospitally was collected. The perceived difficulty of diagnosing AHF and other medical conditions by emergency medical dispatchers and EMS personnel was interrogated. Ultrasound devices and point-of-care testing were available in advanced life support and helicopter EMS units in fewer than 25% of EMS regions. AHF protocols were present in 80.8% of regions. Protocols for ST-elevation myocardial infarction, chest pain, and dyspnoea were present in 95.2, 80.8, and 76.0% of EMS regions, respectively. Protocolized diagnostic actions for AHF management included 12-lead electrocardiogram (92.1% of regions), ultrasound examination (16.0%), and point-of-care testings for troponin and BNP (6.0 and 3.5%). Therapeutic actions included supplementary oxygen (93.2%), non-invasive ventilation (80.7%), intravenous furosemide, opiates, nitroglycerine (69.0, 68.6, and 57.0%), and intubation 71.5%. Diagnosing suspected AHF was considered easy to moderate by EMS personnel and moderate to difficult by emergency medical dispatchers (without significant differences between de novo and decompensated heart failure). In both settings, diagnosis of suspected AHF was considered easier than pulmonary embolism and more difficult than ST-elevation myocardial infarction, asthma, and stroke. Conclusions The prevalence of AHF protocols is rather high but the contents seem to vary. Difficulty of diagnosing suspected AHF seems to be moderate compared with other pre-hospital conditions

Assessment of point-of-care ultrasound of the right upper quadrant of the abdomen

Point of Care UltraSound (PoCUS) is used bedside as part of the clinical examination. Although its clinical integration is currently being promoted in the medical world and facilitated by the improved portability and reduced cost of ultrasound machines, there is still a pressing need to evaluate its diagnostic accuracy, its impact on the diagnostic approach, as well as PoCUS education. PoCUS can be used in many ways during the clinical examination. This analysis mainly focuses on PoCUS use to assess the right upper quadrant of the abdomen. This work aims to collect data about PoCUS diagnostic accuracy for gallbladder assessment, to evaluate the impact of PoCUS of the right upper quadrant on the diagnostic approach, and to explore PoCUS teaching opportunities among undergraduate medical students along with the current state of PoCUS education in medical faculties throughout Europe.(MED - Sciences médicales) -- UCL, 202

A woman with painful lesions of the legs

A 78-year-old woman presented to the emergency department because of weakness and rapidly evolving painful skin lesions. Her medical history was unremarkable, and she was not taking any medications. Physical examination showed irregular violaceous lesions of the right lower limb (figure 1A), knees (figure 1B) and small bullae on the legs (figure 1C). Blood tests were normal; urinalysis showed gross haematuria. An ultrasound of the urinary tract showed an invasive tumour of the bladder

A woman with recurrent vomiting and body cramps.

A 68-year-old woman with pancreatic cancer undergoing chemotherapy presented to the emergency department with a week of vomiting and body cramps. Vital signs were: BP 130/70 mm Hg; HR 80 bpm; RR 14 bpm and oxygen saturation 100% while breathing ambient air. Laboratory investigations showed normal calcium, magnesium and albumin levels; hypokalaemia level at 2.3 mmol/L (normal range 3.5–5.0 mmol/L) and bicarbonate level at 42 mmol/L (normal range 22–29 mmol/L).

Are seminal vesicles a potential pitfall during pelvic exploration using point-of-care ultrasound (POCUS)?

BACKGROUND: Trauma is a major cause of death among the working population. Many countries have now adopted a structured approach to trauma management in which ultrasound is used as a primary evaluation tool. While its use has direct therapeutic benefits, many artifacts and pitfalls are inherent to the technique. Knowledge of the most frequently encountered pitfalls in practice could thus help reduce the risk of error and lead to more accurate trauma assessments. OBJECTIVE: This study evaluates a potential pitfall caused by seminal vesicles during focused assessment with sonography for trauma examinations of the male pelvis performed by an emergency physician with experience in point-of-care ultrasound. METHODS: We took five static and five dynamic (3-s loops) transverse ultrasound images of the pelvis in five healthy males. The images and videos were then incorporated into an online survey and emailed through the World Interactive Network Focused On Critical UltraSound (WINFOCUS) in France and the Ultrasound and Emergency Medicine (UEM) Organization in Belgium. A questionnaire asked anonymous participants to assess the presence of free fluid in the static and dynamic images and to share information about their training and experience in point-of-care ultrasound. To validate the static and dynamic images, the survey was sent to three external radiologists for independent verification. RESULTS: A total of 191 individuals responded fully or partially to the survey, 114 of whom completed it. Among the 114 participants who completed the survey, the misinterpretation rate was 0.55 (95CI 0.51-0.60) for all static and dynamic ultrasound transverse pelvic views. The misinterpretation rate was 0.61 (95CI 0.55-0.66) and 0.50 (95CI 0.45-0.55) for static and dynamic ultrasound transverse pelvic views, respectively. The three external radiologists answered the questionnaire correctly without misinterpreting the survey ultrasound views. CONCLUSIONS: Seminal vesicles are a potential pitfall when interpreting transverse ultrasound images of the male pelvis in the context of point-of-care ultrasound
