Point-of-care ultrasound for the diagnosis of an atypical small bowel obstruction in a cannabis user: a case report.

This case report describes an atypical small bowel obstruction in a 71- years old cannabis user and how point-of-care of ultrasound (PoCUS) helped to its management by further orientating the physician toward the bowel obstruction etiology, namely intussusception. Intussusception is the invagination of an intestinal segment into the adjacent segment. The acute clinical presentation of intussusception often has non-specific symptoms, and the diagnosis can be challenging. While the most common etiology is neoplasm, intussusception also occurs in bowel motility disorder such as after cannabis use. Although this case report illustrates intussusception PoCUS findings, these should nevertheless be integrated into the clinical picture and CT-scan should remain the gold standard complementary examination in case of a suspected bowel obstruction.

Point-of-Care Ultrasound training in undergraduate education in the European Union: current situation and perspectives.

BACKGROUND: Given the widespread use of Point-of-Care UltraSound (PoCUS) in clinical practice, with ultrasound machines becoming more portable and affordable, recommendations and position statements from ultrasound societies now promote teaching PoCUS in the undergraduate curriculum. Nevertheless, surveys about PoCUS teaching in European medical schools are lacking. This survey aims to overview the current and future undergraduate PoCUS courses in the European Union (EU). RESULTS: A questionnaire was sent to medical schools in 26 of the 27 countries of the EU; Luxembourg is the only country without a medical school. The survey was completed by the dean or a member of the medical school with knowledge of the medical curriculum. Of the 58 medical schools from 19 countries that responded to the survey, 18 (31.0%) from 13 (68.4%) EU countries reported the existence of an undergraduate PoCUS curriculum and a further 16 (27.6%) from 12 (41.4%) EU countries intended to offer it in the future. No significant difference was observed between the current and future PoCUS curricula regarding its content and purpose. Less than 40 h of theoretical teaching is provided in all the medical schools and less than 40 h of practical training is provided in 12 (75%) of the 16 medical schools which answered this specific question. Of the 40 (69%) surveyed medical schools that do not currently teach PoCUS, 20 (50%) intend to offer PoCUS courses in the future. CONCLUSION: Although the lack of teaching hours in curricula suggests that most PoCUS courses are introductory in nature and that medical students are possibly not trained to become autonomous in clinical practice, evaluating the feasibility and impact of PoCUS teaching on clinical practice should be promoted. The medical schools that intend to develop this curriculum should be encouraged to implement validated tools to objectively assess their programs and students' performances.

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.

Evaluation of point-of-care ultrasound use in the diagnostic approach for right upper quadrant abdominal pain management in the emergency department: a prospective study.

Point-of-care ultrasound (PoCUS) is commonly used at the bedside in the emergency department (ED) as part of clinical examinations. Studies frequently investigate PoCUS diagnostic accuracy, although its contribution to the overall diagnostic approach is less often evaluated. The primary objective of this prospective, multicenter, cohort study was to assess the contribution of PoCUS to the overall diagnostic approach of patients with right upper quadrant abdominal pain. Two independent members of an adjudication committee, who were blind to the intervention, independently evaluated the diagnostic approaches before and after PoCUS for the same patient. The study included 62 patients admitted to the ED with non-traumatic right upper quadrant abdominal pain from September 1, 2022, to March 6, 2023. The contribution of PoCUS to the diagnostic approach was evaluated using a proportion test assuming that 75% of diagnostic approaches would be better or comparable with PoCUS. Wilcoxon signed-rank tests evaluated the impact of PoCUS on the mean number of differential diagnoses, planned treatments, and complementary diagnostic tests. Overall, 60 (97%) diagnostic approaches were comparable or better with PoCUS (χ2 = 15.9, p < 0.01). With PoCUS, the mean number of differential diagnoses significantly decreased by 2.3 (95% CI - 2.7 to - 1.5) (p < 0.01), proposed treatments by 1.3 (95% CI - 1.8 to - 0.9) (p < 0.01), and complementary diagnostic tests by 1.3 (95% CI - 1.7 to - 1.0) (p < 0.01). These findings show that PoCUS positively impacts the diagnostic approach and significantly decreases the mean number of differential diagnoses, treatments, and complementary tests.

Point-of-Care Ultrasound for the Diagnosis of Pediatric Foreign Body Ingestion: A Narrative Review and Illustrative Case Report.

PURPOSE: Foreign body ingestion (FBI) is a frequent concern in emergency departments. Clinical guidelines recommend performing plain x-rays as the primary modality of diagnosis. Although point-of-care ultrasound (PoCUS) has increasingly been integrated into the daily practice of emergency medicine, it has been poorly investigated in the diagnostic approach for FBI.This review aims to highlight the current state of PoCUS use for pediatric FBI.The following research question was considered in this narrative review: Is PoCUS useful for FBI management? METHODS: A literature search was conducted to identify articles reporting PoCUS use for the management of FBI. All articles were assessed for quality by 2 reviewers. MAIN RESULTS: The 14 selected articles reported 52 FBI cases in which PoCUS successfully identified and located the ingested FB. Point-of-care ultrasound was used either as the primary imaging technique or after positive or negative x-ray findings. In 5 cases (9.6%), PoCUS was the only modality used for the diagnosis. Of these cases, 3 (60%) underwent a successful procedure to remove the FB and 2 (40%) received conservative treatment without complications. CONCLUSIONS: This review suggests that PoCUS might be a reliable modality for the initial management of FBI. PoCUS can locate, identify, and evaluate the size of the FB in a wide range of materials and gastrointestinal locations. Point-of-care ultrasound could eventually become the go-to modality in the case of radiolucent FB, thus avoiding the use of radiation. Further studies are nevertheless required to validate PoCUS use for FBI management.

Is gallbladder PoCUS diagnostic accuracy accessible to medical students after PoCUS training exclusively on healthy volunteers? A pilot randomized control trial.

BACKGROUND: Point-of-care ultrasound (PoCUS) is increasingly used in clinical practice and is now included in many undergraduate curricula. Here, we aimed to determine whether medical students who participated in a PoCUS teaching program with several practical training sessions involving healthy volunteers could achieve a good level of diagnostic accuracy in identifying gallbladder pathologies. The intervention group (IG) was trained exclusively on volunteers with a healthy gallbladder, whereas the control group (CG) had access to volunteers with a pathological gallbladder as recommended in most PoCUS curricula. MATERIALS AND METHODS: Twenty medical students were randomly assigned to the IG and CG. After completing the training program over 2 months, students were evaluated by three independent examiners. Students and examiners were blind to group allocation and study outcome. Sensitivity and specificity of students' PoCUS gallstone diagnosis were assessed. Secondary outcomes were students' confidence, image quality, acquisition time, and PoCUS skills. RESULTS: Sensitivity and specificity for gallstone diagnosis were, respectively, 0.85 and 0.97 in the IG and 0.80 and 0.83 in the CG. Areas under the curve (AUC) based on the receiver operating characteristic curve analysis were 0.91 and 0.82 in the IG and CG, respectively, with no significant difference (p = 0.271) and an AUC difference of -0.092. No significant between-group difference was found for the secondary outcomes. CONCLUSIONS: Our pilot study showed that medical students can develop PoCUS diagnostic accuracy after training on healthy volunteers. If these findings are confirmed in a larger sample, this could favor the delivery of large practical teaching sessions without the need to include patients with pathology, thus facilitating PoCUS training for students.

Point-of-care ultrasonography for risk stratification of non-critical suspected COVID-19 patients on admission (POCUSCO): A prospective binational study.

BACKGROUND: Lung point-of-care ultrasonography (L-POCUS) is highly effective in detecting pulmonary peripheral patterns and may allow early identification of patients who are likely to develop an acute respiratory distress syndrome (ARDS). We hypothesized that L-POCUS performed within the first 48 hours of non-critical patients with suspected COVID-19 would identify those with a high-risk of worsening. METHODS: POCUSCO was a prospective, multicenter study. Non-critical adult patients who presented to the emergency department (ED) for suspected or confirmed COVID-19 were included and had L-POCUS performed within 48 hours following ED presentation. The lung damage severity was assessed using a previously developed score reflecting both the extension and the intensity of lung damage. The primary outcome was the rate of patients requiring intubation or who died within 14 days following inclusion. RESULTS: Among 296 patients, 8 (2.7%) met the primary outcome. The area under the curve (AUC) of L-POCUS was 0.80 [95%CI:0.60-0.94]. The score values which achieved a sensibility >95% in defining low-risk patients and a specificity >95% in defining high-risk patients were <1 and ≥16, respectively. The rate of patients with an unfavorable outcome was 0/95 (0%[95%CI:0-3.9]) for low-risk patients (score = 0), 4/184 (2.17%[95%CI:0.8-5.5]) for intermediate-risk patients (score 1-15) and 4/17 (23.5%[95%CI:11.4-42.4]) for high-risk patients (score ≥16). In confirmed COVID-19 patients (n = 58), the AUC of L-POCUS was 0.97 [95%CI:0.92-1.00]. CONCLUSION: L-POCUS performed within the first 48 hours following ED presentation allows risk-stratification of patients with non-severe COVID-19.

Use of procedural ultrasound for the insertion of peripheral intravenous catheters: A nationwide survey in acute care departments in Belgium.

PURPOSE: Assessment of ultrasound use for peripheral intravenous cannulation among acute care nurses and physicians. METHODS: Over a population of 17,437, the calculated sample size of respondents required was 376. RESULTS: A total of 388 health professionals; 249 (64.2%) physicians and 139 (35.8%) nurses completed the entire questionnaire. 166 (45.2%) used ultrasound for intravenous cannulation. A statistically significant difference favored physicians' ultrasound use (p<0.001). Respondents with less than 10 years of clinical practice used ultrasound significantly more (p<0.001). The main reported obstacle among users was the lack of time. CONCLUSION: This survey revealed the gap between the current recommendations for ultrasound use for peripheral intravenous cannulation and the actual practices. Efforts should be made to develop specific training using ultrasound.

EFSUMB Clinical Practice Guidelines for Point-of-Care Ultrasound: Part One (Common Heart and Pulmonary Applications) SHORT VERSION.

OBJECTIVE: To evaluate the evidence and produce a summary and recommendations for the most common heart and lung point-of-care ultrasound (PoCUS). METHODS: We reviewed 10 clinical domains/questions related to common heart and lung applications of PoCUS. Following review of the evidence, a summary and recommendations were produced, including assigning levels of evidence (LoE) and grading of recommendation, assessment, development, and evaluation (GRADE). 38 international experts, the expert review group (ERG), were invited to review the evidence presented for each question. A level of agreement of over 75 % was required to progress to the next section. The ERG then reviewed and indicated their level of agreement of the summary and recommendation for each question (using a 5-point Likert scale), which was approved in the case of a level of agreement of greater than 75 %. A level of agreement was defined as a summary of "strongly agree" and "agree" on the Likert scale responses. FINDINGS AND RECOMMENDATIONS: One question achieved a strong consensus for an assigned LoE of 3 and a weak GRADE recommendation (question 1), the remaining 9 questions achieved broad agreement with an assigned LoE of 4 and a weak GRADE recommendation (question 2), three achieved an LoE of 3 with a weak GRADE recommendation (questions 3-5), three achieved an LoE of 3 with a strong GRADE recommendation (questions 6-8) and the remaining two were assigned an LoE of 2 with a strong GRADE recommendation (questions 9 and 10). CONCLUSION: These consensus-derived recommendations should aid clinical practice and highlight areas of further research for PoCUS in acute settings.

CONCLUSION: These consensus-derived recommendations should aid clinical practice and highlight areas of further research for PoCUS in acute settings.

'Adequacy between medical prescription and intake of analgesics for acute low back and neck pain after presentation at the emergency department - do we prescribe too many tablets?'

OBJECTIVES: Acute low back and neck pain account for 3% to 6% of emergency room consultations. In Europe, analgesic prescriptions are issued in boxes. This study, therefore, aims to assess whether this type of packaging is adapted to the real needs of patients. METHODS: This is a prospective observational multicenter study. Out of a total of 101 eligible patients who consulted the emergency department with acute low back or neck pain of muscular origin, 60 patients were included for statistical analysis. Follow-up was conducted by phone 10 to 14 days after admission. Different parameters were evaluated: the recovery, the amount of remaining tablets, and the demographic characteristics of patients. RESULTS: Seventy-five percent of the evaluated patients were asymptomatic at follow-up and no longer taking the prescribed treatment. For all types of prescribed analgesics, a significant number of tablets remained in the drug boxes (P < 0.0001). After the resolution of symptoms, 90% of the studied patients reported a drug surplus. No significant difference was found in terms of patient demographic characteristics. The results were similar for both neck and low back pain subgroups. CONCLUSION: This study suggests that in case of acute low back and neck pain, a significant number of patients who return home after an emergency department consultation have a surplus of analgesics after recovery. These drugs could induce misuse. Moreover, this surplus gives rise to economic and environmental questions. One solution could be to prescribe a number of tablets depending on patients' pathology instead of entire boxes.

Correlation between hypoxaemia and lung ultrasound score in patients presenting to an emergency department with interstitial syndrome: a prospective physiological study.

Objective: To assess for the presence of a correlation between lung ultrasound score (LUSS) and ratio between arterial partial pressure of oxygen (PaO2) and the fraction of inspired oxygen (FiO2) in patients presenting to an emergency department (ED) with interstitial syndrome (IS). Design: Prospective, multicentre, physiological study. Setting: Four Belgian hospitals: one tertiary academic centre and three secondary centres. Participants: A convenience sample of adult patients who presented to an ED with acute dyspnoea and needed an arterial blood gas (ABG) analysis (those with a LUSS < 2 were secondarily excluded). Main outcome measure: Correlation between PaO2/FIO2 and LUSS determined using Pearson correlation. Results: In total, 162 adult patients were included. A statistically significant negative linear correlation between PaO2/FIO2 and LUSS was found (correlation coefficient, -0.4860 [95% CI, -0.5956 to -0.3587]; P < 0.0001). Conclusions: Our data provide evidence of a statistically significant negative linear correlation between PaO2/FIO2 and LUSS for ED patients with lung IS. Given the representativeness of PaO2/FIO2 for hypoxaemia and the fact that hypoxaemia indicates IS severity, our findings suggest that LUSS could contribute to the evaluation of IS severity. If confirmed by future studies that include patient follow-up, a noninvasive approach using LUSS could decrease the need for ABG analysis in patients who do not require repeated measurement of ABG values other than PaO2, and thereby improve patient comfort.

Performance of Different Low-Flow Oxygen Delivery Systems.

BACKGROUND: The delivery of a high and consistent [Formula: see text] is imperative to treat acute hypoxemia. The objective of this study was to analyze the effective inspired oxygen concentration delivered by different low-flow oxygen therapy systems challenged with different oxygen flows and respiratory patterns in an experimental lung model. METHODS: An adult lung model ventilated in volume control mode simulated different respiratory patterns to obtain mean inspiratory flow of 22.5, 30.0, 37.5, or 45.0 L/min. The oxygen concentration sampled inside the lung model by nasal cannula, simple face mask, non-rebreather mask, and double-trunk mask above nasal cannula tested at oxygen flows of 10, 12.5, and 15 L/min was quantified. The 3 masks were sealed tight onto the model's airway opening. They were also tested with standardized leaks to determine their clinical performance. RESULTS: All oxygen delivery systems delivered higher oxygen concentration with increasing oxygen flows, regardless of the respiratory pattern. Within each device, the increase in inspiratory flow decreased oxygen concentration when using nasal cannula (P = .03), the simple face mask (P = .03), but not the non-rebreather mask (P = .051) nor the double-trunk mask (P = .13). In sealed condition, the double-trunk mask outperformed the non-rebreather mask and simple face mask (P < .001); mean oxygen concentration was 84.2%, 68.5%, and 60.8%, respectively. Leaks amplified oxygen concentration differences between the double-trunk mask and the other masks as the oxygen delivery decreased by 4.6% with simple face mask (95% CI 3.1-6.1%, P < .001), 7.8% with non-rebreather mask (95% CI 6.3-9.3%, P < .001), and 2.5% with double-trunk mask (95% CI 1-4%, P = .002). With leaks, the oxygen concentration provided by the simple face mask and the non-rebreather mask was similar (P = .15). CONCLUSIONS: Lung oxygen concentration values delivered by the double-trunk mask were higher than those obtained with other oxygen delivery systems, especially when leaks were present.

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.

Agreement of emergency physician-performed ultrasound versus RADiology-performed UltraSound for cholelithiasis or cholecystitis: a systematic review.

Cholecystitis secondary to gallstone migration is the most common suspected diagnosis for right upper quadrant pain in emergency departments, with radiology-performed ultrasound (RADUS) being the main diagnostic tool. The primary aim of this review was to assess the ability of emergency physicians to perform emergency ultrasound (EUS) compared to RADUS to diagnose cholelithiasis and cholecystitis. A systematic search was performed using Embase, Central (Cochrane library), Web of Science, MEDLINE, Google Scholar, prospective trial registries, and OpenSIGLE databases as well as hand-search of articles. Two physicians independently selected the articles. Assessment of methodological quality was performed using the Quality Assessment of Diagnostic Accuracy Studies 2 tool. Clinical and methodological heterogeneity were qualitatively reported and discussed. Seven prospective studies were selected involving a total of 1061 subjects undergoing EUS. The included studies all used RADUS as the reference standard and emergency physician-performed EUS as the index test. Included studies mostly reported diagnostic accuracy for cholelithiasis diagnosis whereas only one study mentioned diagnostic accuracy for cholecystitis. Clinical and methodological heterogeneity between included studies prevented a meta-analysis. This review shows there is good agreement between EUS and RADUS to assess the gallbladder for cholelithiasis and therefore supports its use by emergency physicians for that matter. Nevertheless, this work identified clinical and methodological heterogeneity along with a poor description EUS operators' experience. In the future, larger studies should include a larger population of EUS operators, specify their background, and compare EUS to the final diagnosis to evaluate performances for gallbladder diagnostic accuracy.

Point-of-care ultrasonography for risk stratification of non-critical COVID-19 patients on admission (POCUSCO): a study protocol of an international study.

INTRODUCTION: In the context of the COVID-19 pandemic, early identification of patients who are likely to get worse is a major concern. Severity mainly depends on the development of acute respiratory distress syndrome (ARDS) with a predominance of subpleural lesions. Lung point-of-care ultrasonography (L-POCUS) is highly effective in detecting pulmonary peripheral patterns and may be appropriate for examining patients with COVID-19. We suggest that L-POCUS performed during the initial examination may identify patients with COVID-19 who are at a high risk of complicated treatment or unfavourable evolution. METHODS AND ANALYSIS: Point-of-care ultrasonography for risk stratification of non-critical COVID-19 patients on admission is a prospective, multicentre study. Adult patients visiting the emergency department (ED) of participating centres for suspected or confirmed COVID-19 are assessed for inclusion. Included patients have L-POCUS performed within 48 hours following ED admission. The severity of lung damage is assessed using the L-POCUS score based on 36 points for ARDS. Apart from the L-POCUS score assessment, patients are treated as recommended by the WHO. For hospitalised patients, a second L-POCUS is performed at day 5±3. A follow-up is carried out on day 14, and the patient's status according to the Ordinal Scale for Clinical Improvement for COVID-19 from the WHO is recorded.The primary outcome is the rate of patients requiring intubation or who are dead from any cause during the 14 days following inclusion. We will determine the area under the ROC curve of L-POCUS. ETHICS AND DISSEMINATION: The protocol has been approved by the French and Belgian Ethics Committees and is carried out in accordance with the Declaration of Helsinki and Good Clinical Practice guidelines. The study is funding by a grant from the French Health Ministry, and its findings will be disseminated in peer-reviewed journals and at scientific conferences. TRIAL REGISTRATION NUMBER: NCT04338100.

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.
