Introduction: Cephalohematomas generally do not pose a significant risk to the patient and resolve spontaneously. Conversely, a subgaleal hematoma is a rare but more serious condition. While it may be challenging to make this diagnostic distinction based on a physical examination alone, the findings that differentiate these two conditions can be appreciated on point-of-care ultrasound (POCUS). We describe two pediatric patient cases where POCUS was used to distinguish between a subgaleal hematoma and a cephalohematoma.Case Reports: We describe one case of a 14-month-old male brought to the pediatric emergency department (PED) with concern for head injury. A POCUS examination revealed a large fluid collection that did not cross the sagittal suture. Thus, the hematoma was more consistent with a cephalohematoma and less compatible with a subgaleal hematoma. Given these findings, further emergent imaging was deferred in the PED and the patient was kept for observation. In the second case an 8-week-old male presented with suspected swelling over the right parietal region. A POCUS examination was performed, which demonstrated an extensive, simple fluid collection that extended across the suture line, making it more concerning for a subgaleal hematoma. Given the heightened suspicion for a subgaleal hematoma, the patient was admitted for further imaging and evaluation.Conclusion: Point-of-care ultrasound can be used to help differentiate between a subgaleal hematoma and a cephalohematoma to risk-stratify patients and determine the need for further imaging.

Introduction: Pott’s puffy tumor (PPT) is a rare clinical disease characterized by forehead swelling from a subperiosteal abscess coupled with frontal bone osteomyelitis. It is often associated with severe complications and poor outcomes if left undiagnosed; thus, rapid recognition is crucial. Point-of-care ultrasound (POCUS) may provide an alternative pathway to diagnosis. It can be performed rapidly at the bedside and assist in early screening of patients, identifying those with high suspicion for PPT and prioritizing imaging and consultation.Case Report: A 59-yghb ar-old-male presented to the emergency department for evaluation of a “lump” on his forehead. He recently had a bifrontal craniotomy to de-bulk a polyp burden in an effort to manage his recurrent sinusitis. To further characterize the mass, a POCUS examination was performed by the treating emergency physician. The examination found a subcutaneous, hypoechoic fluid collection extending superficially along the frontal bone. A discontinuity in the surface of the frontal bone was visualized through which the collection appeared to extend. Given the heightened concern for PPT based on the POCUS examination findings, otolaryngology service was consulted and the patient was admitted for further imaging and treatment.Conclusion: Pott’s puffy tumor is a rare diagnosis that has the potential for life-threatening complications. Timely diagnosis is imperative. Point-of-care ultrasound can easily be used to help identify patients with suspicion for PPT in the acute care setting and influence patient management with regard to obtaining further imaging and plans for early consultation.

Introduction: As physician-performed point-of-care ultrasound (POCUS) becomes more prevalent in the evaluation of patients presenting with various complaints in the emergency department (ED), one application that is significantly less used is breast ultrasound. This study evaluates the utility of POCUS for the assessment of patients with breast complaints who present to the ED and the impact of POCUS on medical decision-making and patient management in the ED.Methods: This was a retrospective review of ED patients presenting with breast symptoms who received a POCUS examination. An ED POCUS database was reviewed for breast POCUS examinations. We then reviewed electronic health records for demographic characteristics, history, physical examination findings, ED course, additional imaging studies, and impact of the POCUS study on patient care and disposition.Results: We included a total of 40 subjects (36 females, 4 males) in the final analysis. Most common presenting symptoms were breast pain (57.5%) and a palpable mass (37.5%). “Cobblestoning,” ie, dense bumpy appearance, was the most common finding on breast POCUS, seen in 50% of the patients. Simple fluid collections were found in 37.5% of patients.Conclusion: Our study findings illustrate the utility of POCUS in the evaluation of a varietyof breast complaints in the ED.

As emergency physicians are looking at handheld devices as alternatives to the traditional, cart-based systems, concerns center around whether they are forsaking image quality for a lower price point and whether the handheld can be trusted for medical decision making. We aimed to determine the feasibility of using a handheld ultrasound device in place of a cart-based system during the evaluation of trauma patients using the Focused Assessment with Sonography for Trauma (FAST) examination. This was a prospective study of adult trauma patients who received a FAST examination as part of their evaluation. A FAST examination was performed using a cart-based machine and a handheld device. The results of the examinations were compared with computed tomography imaging. Images obtained from both ultrasound devices were reviewed by an expert for image quality. A total of 62 patients were enrolled in the study. The mean (SD) time to perform a FAST examination using the handheld device was 307.3 (65.3) s, which was significantly less (p = 0.002) than the 336.1 (86.8) s with the cart-based machine. There was strong agreement between the examination results of the handheld and cart-based devices and between the handheld and computed tomography. Image quality scores obtained with the handheld device were lower than those from the cart-based system. Most operators and reviewers agreed that the images obtained from the handheld were adequate for medical decision making. Data support that it is feasible to use the handheld ultrasound device for evaluation of the trauma patient in place of the cart-based system. [ABSTRACT FROM AUTHOR]

Objectives: The purpose of this study was to evaluate the performance of a handheld ultrasound device for difficult peripheral intravenous (PIV) access performed by nurses and paramedics in the emergency department (ED). Methods: This was a retrospective review at an academic medical center. Participants were ED nurses and paramedics with competence in ultrasound‐guided PIV placement. Participants were asked to log their use of the handheld device when used on patients deemed to have "difficult" access and complete a questionnaire, which consisted of items related to the effectiveness and ease of use of the device. Data were collected over the course of 1 year. An electronic medical record review was performed to track the success rates and the occurrence of any associated complications throughout the hospital stay. Results: Nurses and paramedics logged a total of 483 cases in which PIV access was attempted with the handheld ultrasound device. Ninety‐two percent (95% confidence interval [CI], 89%–94%) of the ultrasound‐guided PIV lines attempted were placed successfully. Eighty‐four percent (95% CI, 80%–87%) of the lines were placed successfully on the first attempt. In most cases (396 of 483 [82%]), no complications associated with the PIV occurred. A total of 429 questionnaires were completed over the study period. Most of the operators (84%; 95% CI, 80%–87%) stated that the handheld device was adequate to perform ultrasound‐guided PIV access. Conclusions: The handheld ultrasound device performed well in terms of usability and reliability for PIV access. [ABSTRACT FROM AUTHOR]

Objectives: Prior literature has demonstrated incongruities among faculty evaluation of male and female residents' procedural competency during residency training. There are no known studies investigating gender differences in the assessment of procedural skills among emergency medicine (EM) residents, such as those required by ultrasound. The objective of this study was to determine if there are significant gender differences in ultrasound milestone evaluations during EM residency training. Methods: We used a stratified, random cluster sample of Accreditation Council for Graduate Medical Education (ACGME) EM residency programs to conduct a longitudinal, retrospective cohort analysis of resident ultrasound milestone evaluation data. Milestone evaluation data were collected from a total of 16 ACGME‐accredited EM residency programs representing a 4‐year period. We stratified milestone data by resident gender, date of evaluation, resident postgraduate year, and cohort (residents with the same starting date). Results: A total of 2,554 ultrasound milestone evaluations were collected from 1,187 EM residents (750 men [62.8%] and 444 women [37.1%]) by 104 faculty members during the study period. There was no significant overall difference in mean milestone score between female and male residents [mean difference = 0.01 (95% confidence interval {CI} = −0.04 to 0.05)]. There were no significant differences between female and male residents' mean milestone scores at the first (baseline) PGY1 evaluation (mean difference = −0.04 [95% CI = −0.09 to 0.003)] or at the final evaluation during PGY3 (mean difference = 0.02 [95% CI = −0.03 to 0.06)]. Conclusions: Despite prior studies suggesting gender bias in the evaluation of procedural competency during residency training, our study indicates that there were no significant gender‐related differences in the ultrasound milestone evaluations among EM residents within training programs throughout the United States.

Objectives: To determine the feasibility of integrating pre-intubation ultrasound into airway course and assess emergency medicine (EM) residents' confidence and comfort level in using ultrasound for pre-intubation hemodynamic stabilization and identifying cricothyroid membrane after the training session. Materials and methods: This is a retrospective study. Pre-intubation ultrasound training was delivered with the following ultrasound components (didactics and hands-on sessions using human models) to EM residents: (1) sonoanatomy and scanning technique to identify cricothyroid membrane and (2) pre-intubation echocardiography for recognition of acute right ventricular failure and pre-intubation hemodynamic stabilization. Results: A total of 56 EM residents participated in this study. Only 21% [95% confidence interval (CI), 10-31%] reported using ultrasound for pre-intubation hemodynamic stabilization. After the training session, 89% (95% CI, 81-97%) reported that ultrasound-based teaching increased their knowledge of pre-intubation hemodynamic stabilization compared with traditional teaching methods. On a scale of 1 (low) through 10 (high), the average comfort level for integrating ultrasound findings into medical decision making for pre-intubation hemodynamic stabilization was 6.8 (95% CI, 6.3-7.3). Seventy-nine percent (95% CI, 68-89%) reported that focused training in airway ultrasound is adequate to identify cricothyroid membrane. On a scale of 1 (low) through 10 (high), the average confidence level for identifying cricothyroid membrane using ultrasound was 6.6 (95% CI, 6.1-7.1). Conclusion: At our institution, we successfully integrated pre-intubation ultrasound into an airway course. Emergency medicine residents had a moderate level of comfort and confidence level using ultrasound for pre-intubation hemodynamic stabilization and identifying cricothyroid membrane after the training session.

Aim: Regional anesthesia with ultrasound-guidance is an excellent option for pain control if nerves are adequately visualized. Gender, body mass index (BMI), history of diabetes, neck and forearm circumference may affect echotexture and visualization. This study evaluates patient characteristics for their ability to predict the echogenicity or visibility of upper extremity peripheral nerves.Material and Methods: This is a prospective observational study. A convenience sample of adult emergency department patients were enrolled. Gender, BMI, history of diabetes, neck circumference and arm circumference were recorded. Sonographic images of the brachial plexus at interscalene and supraclavicular levels, the median, the radial and ulnar nerves were recorded. Three reviewers independently graded the echogenicity and visibility using subjective scales.Results: 395 peripheral nerves were included. Nerves of the forearm (median, ulnar, radial nerves) were found to be more echogenic (OR=9.3; 95% CI: 5.7, 15.3) and visible (OR=10.0; 6.3, 16.0) than more proximal nerves (brachial plexus at interscalene and supraclavicular levels). Gender, BMI, and history of diabetes mellitus were not significantly related to nerve visibility (p=0.9, 0.2, 0.2, respectively) or echogenicity (p=0.3, 0.8, 0.3). Neck circumference was not related to visibility or echogenicity of proximal nerves. Increased forearm circumference improved echogenicity (OR=1.25; 1.09, 1.43) but not visibility of forearm nerves.Conclusions: Gender, BMI and presence of diabetes were not related to echogenicity or visibility of upper extremity nerves. Increasing forearm circumference was associated with increased echogenicity of the adjacent nerves, but not visibility. Neck circumference was not associated with either nerve visibility or echogenicity of brachial plexus nerve bundles. [ABSTRACT FROM AUTHOR]
