Abstract
In December 2022, the American Academy of Pediatrics released a clinical guideline for point-of-care ultrasonography (POCUS) in the neonatal intensive care unit (NICU). The guideline outlined the development and current status of POCUS in the NICU, and summarized the key elements and implementation guidelines for successful implementation of POCUS in the NICU. This article provides an overview of the key points of the clinical guideline and analyzes the current status of POCUS in China, providing a reference for the implementation of POCUS in neonatal care in China.

Abstract
Importance The wide variation in the accuracy and reliability of the Focused Assessment With Sonography for Trauma (FAST) and the extended FAST (E-FAST) for children after blunt abdominal trauma reflects user expertise. FAST and E-FAST that are performed by experts tend to be more complete, better quality, and more often clinically valuable. Objective To develop definitions of a complete, high-quality, and accurate interpretation for the FAST and E-FAST in children with injury using an expert, consensus-based modified Delphi technique. Design, Setting, and Participants This consensus-based qualitative study was conducted between May 1 to June 30, 2021. It used a scoping review and iterative Delphi technique and involved 2 rounds of online surveys and a live webinar to achieve consensus among a 26-member panel. This panel consisted of international experts in pediatric emergency point-of-care ultrasonography. Main Outcomes and Measures Definitions of complete, high-quality, and accurate FAST and E-FAST studies for children after injury. Results Of the 29 invited pediatric FAST experts, 26 (15 men [58%]) agreed to participate in the panel. All 26 panelists completed the 2 rounds of surveys, and 24 (92%) participated in the live and asynchronous online discussions. Consensus was reached on FAST and E-FAST study definitions, and the panelists rated these 5 anatomic views as important and appropriate for a complete FAST: right upper-quadrant abdominal view, left upper-quadrant abdominal view, suprapubic views (transverse and sagittal), and subxiphoid cardiac view. For E-FAST, the same FAST anatomic views with the addition of the lung or pneumothorax view were deemed appropriate and important. In addition, the panelists rated a total of 32 landmarks as important for assessing completeness. Similarly, the panelists rated 14 statements on quality and 20 statements on accurate interpretation as appropriate. Conclusions and Relevance This qualitative study generated definitions for complete FAST and E-FAST studies with high image quality and accurate interpretation in children with injury. These definitions are similar to those in adults with injury and may be used for future education, quality assurance, and research. Future research may focus on interpretation of trace volumes of abdominal free fluid and the use of serial FAST.

Abstract
BACKGROUND Focused Assessment with Sonography for Trauma (FAST) has supplanted diagnostic peritoneal lavage (DPL) as the preferred bedside evaluation for traumatic hemoperitoneum. Diagnostic peritoneal aspiration (DPA) is a simpler, faster modification of DPL with an unclear role in contemporary practice. This study delineated modern roles for DPA and defined its diagnostic yield. METHODS All trauma patients presenting to our Level I center who underwent DPA were included (May 2015 to May 2020). Demographics, comorbidities, clinical/injury data, and outcomes were collected. The diagnostic yield and accuracy of DPA were calculated against the criterion standard of hemoperitoneum at exploratory laparotomy or computed tomography scan. RESULTS In total, 41 patients underwent DPA, typically after blunt trauma (n = 37, 90%). Patients were almost exclusively hypotensive (n = 20, 49%) or in arrest (n = 18, 44%). Most patients had an equivocal or negative FAST and hypotension or return of spontaneous circulation after resuscitative thoracotomy (n = 32, 78%); or had a positive FAST and known cirrhosis (n = 4, 10%). In two (5%) patients, one obese, the catheter failed to access the peritoneal cavity. Diagnostic peritoneal aspiration sensitivity, specificity, positive predictive value, and negative predictive value were 80%, 100%, 100%, and 90%, with an accuracy of 93%. One (2%) complication, a small bowel injury, occurred. CONCLUSION Despite near ubiquitous FAST availability, DPA remains important in diagnosing or excluding hemoperitoneum with exceedingly low rates of failure and complications. Diagnostic peritoneal aspiration is most conclusive when positive, without false positives in this study. Diagnostic peritoneal aspiration was most used among blunt hypotensive or postarrest patients who had an equivocal or negative FAST, in whom the preliminary diagnosis of hemoperitoneum is a critically important decision making branch point. LEVEL OF EVIDENCE Diagnostic, level III.

Abstract
BACKGROUND The use of Focused Assessment with Sonography for Trauma (FAST) in combination with computed tomography (CT) has become the mainstay of diagnostic workup in patients with suspected intraabdominal hemorrhage (IAH). However, diagnostic peritoneal aspiration (DPA) can be an important adjunct in hemodynamically unstable patients. The aim of this study was to evaluate the utility and diagnostic accuracy of DPA in detecting IAH. METHODS Retrospective analysis of all patients who presented to the LAC+USC Medical Center and underwent evaluation with DPA between January 2010 and December 2016. Intraoperative, CT, and autopsy findings were used as gold standards in determining the diagnostic accuracy of DPA for the detection of IAH. RESULTS A total of 73 consecutive patients were included in the study. The median age was 42 years (interquartile range [IQR]: 25-56), median injury severity score was 29 (IQR: 21-41), and 82.2% sustained blunt trauma. The most common indications for DPA were hemodynamically unstable patients with suspected IAH and patients with return of spontaneous circulation following resuscitative thoracotomy. Overall, the positive and negative predictive values of DPA were 89.4% and 88.9%, respectively. In 14 cases (19.2%), DPA correctly identified false positive/negative FAST results. CONCLUSION Our data suggest that DPA has high diagnostic yield for IAH. The use of DPA should be considered in unstable patients with inconclusive FAST results who cannot safely be evaluated with CT.

Abstract
Blunt cardiac injury (BCI), defined as an injury to the heart from blunt force trauma, ranges from minor to life-threatening. The majority of BCIs are due to motor vehicle accidents; however, injuries caused by falls, blasts, and sports-related injuries also can be sources of BCI. A significant proportion of patients with BCI do not survive long enough to receive medical care, succumbing to their injuries at the scene of the accident. Additionally, patients with blunt trauma often have coexisting injuries (brain, spine, orthopedic) that can obscure the clinical picture; therefore, a high degree of suspicion often is required to diagnose BCI. Traditionally, hemodynamically stable injuries suspicious for BCI have been evaluated with electrocardiograms and chest radiographs, whereas hemodynamically unstable BCIs have received operative intervention. More recently, computed tomography and echocardiography increasingly have been utilized to identify injuries more rapidly in hemodynamically unstable patients. Transesophageal echocardiography can play an important role in the diagnosis and management of several BCIs that require operative repair. Close communication with the surgical team and access to blood products for potentially massive transfusion also play key roles in maintaining hemodynamic stability. With proper surgical and anesthetic care, survival in cases involving urgent cardiac repair can reach 66%-to-75%. This narrative review focuses on the types of cardiac injuries that are caused by blunt chest trauma, the modalities and techniques currently used to diagnose BCI, and the perioperative management of injuries that require surgical correction.

Abstract
OBJECTIVE Free intra-abdominal fluid describes an accumulation of free fluid in the peritoneal cavity. It has different etiologies, but it frequently constitutes a meaningful clinical sign. In this study, the authors interrogate whether abdominal ultrasound augments the medical students' ability to identify free intra-abdominal fluid. METHODS Thirty-one medical students without any previous formal ultrasound training were subjected to cognitive assessment before and after four and a half-hour of theoretical lecture and hands-on course about the diagnosis of free intra-abdominal fluid by physical examination and abdominal ultrasound. The hands-on sessions were done in healthy volunteers with a simulated peritoneal catheter and in patients treated with peritoneal dialysis with different amounts of dialysate in their cavity. RESULTS The cognitive assessment before and after the course increased from 6.7±2.3 to 11.6±1.1 points (p<0.0001). The sensitivity, specificity, and accuracy in the diagnosis of free intra-abdominal fluid were higher when students used abdominal ultrasound. The students agree with the inclusion of abdominal ultrasound in the diagnose of free intra-abdominal fluid in the undergraduate curriculum. CONCLUSIONS This study demonstrates that incorporating abdominal ultrasound is feasible and improves medical students' short-time competency in performing and interpreting the findings diagnostic of free intra-abdominal fluid.

Predictors for Direct to Operating Room Admission in Severe Trauma. J Surg Res 2021; 261:274-281.

Abstract
BACKGROUND Protocols for expediting critical trauma patients directly from the helipad to the operating room tend to vary by center, rely heavily on physician gestalt, and lack supporting evidence. We evaluated a population of severely injured trauma patients with the aim of determining objective factors associated with the need for immediate surgical intervention. METHODS All highest-activation trauma patients transported by air ambulance between 1/1/16 and 12/31/17 were enrolled retrospectively. Transfer, pediatric, isolated burn, and isolated head trauma patients were excluded. Patients who underwent emergency general surgery within 30 min of arrival without the aid of cross-sectional imaging were compared to the remainder of the cohort. RESULTS Of the 863 patients who were enrolled, 85 (10%) spent less than 30 min in the emergency department (ED) before undergoing an emergency operation. The remaining 778 patients (90%) formed the comparison group. The ED ≤ 30 min group had a higher percentage of penetrating injuries, lower blood pressure, and was more likely to have a positive FAST exam. The "Direct to Operating Room" (DTOR) score is a predictive scoring system devised to identify patients most likely to benefit from bypassing the ED. The odds ratio of emergency operation within 30 min of hospital arrival increased by 2.71 (95% confidence interval 2.23-3.29; P < 0.001) for every 1-point increase in DTOR score. CONCLUSIONS Trauma patients with profound hypotension or acidosis and positive FAST were more likely to require surgery within 30 min of hospital presentation. Use of a scoring system may allow early identification of these patients in the prehospital setting by nonphysician providers.

Abstract
BACKGROUND Use of the focused assessment with sonography for trauma (FAST) examination in patients with pelvic fractures has been reported as unreliable. We hypothesized that FAST is a reliable method for detecting clinically significant intra-abdominal hemorrhage in patients with pelvic fractures. METHODS All patients with pelvic fractures over a 10-year period were reviewed at a Level I trauma center. The predictive ability of FAST was assessed by calculating the sensitivity, specificity, positive predictive value and negative predictive value against the criterion standard of either computed tomography (CT) or laparotomy findings. The FAST examination was considered "false negative" if findings at laparotomy indicated traumatic intra-abdominal hemorrhage. Likewise, the FAST examination was considered "false positive" if either CT or findings at laparotomy indicated no intra-abdominal hemorrhage. Hemodynamic instability scores were calculated for all patients. RESULTS There were 1,456 patients with pelvic fractures and an initial FAST reviewed; 1,219 (83.7%) underwent FAST and either CT or operative exploration. Median age was 43 years (interquartile range, 26-56 years) and mean Injury Severity Score was 18.5 ± 12.3. The sensitivity and specificity for FAST in this group of patients with pelvic fracture was 85.4% and 98.1%, respectively. The positive predictive value and negative predictive value were 78.4% and 98.8%, respectively. Of 21 patients with a false-positive FAST, 15 (71.4%) were confirmed with a negative CT scan, and 6 (28.6%) underwent laparotomy without findings of intra-abdominal hemorrhage. Of 13 patients with a false-negative FAST, all were identified with positive findings at the time of laparotomy. The specificity of the FAST examination remained high regardless of hemodynamic instability score grade. CONCLUSION The false positive rate of FAST examination for intra-abdominal hemorrhage is 1.1%. These data suggest that a positive FAST in this clinical scenario should be considered to represent intra-abdominal fluid. This series contradicts prior reports that FAST is unreliable in patients with pelvic fracture. LEVEL OF EVIDENCE Diagnostic, level III.

Abstract
BACKGROUND Systematic Sonography Looking for Occult Wounds (SSLOW) in trauma is a novel technique for the evaluation of intra-abdominal wounds in penetrating trauma. No data exist regarding the effectiveness. The objective of this study was to evaluate the accuracy of the SSLOW exam. METHODS This is a prospective collected case series conducted over a period of 10 months and took place at the Accident and Emergency Department (A&E) of the Georgetown Public Hospital Corporation (GPHC). The study enrolled patients presenting to the A&E who were 16 years old or greater with penetrating abdominal trauma. All patients with penetrating trauma received an E-FAST examination. If the E-FAST examination was negative, a SSLOW examination was completed. The sonographer evaluated for free fluid collection between the loops of bowel. The results of the SSLOW were compared to usual care (surgery consult, serial abdominal and E-FAST exams, laparotomy, and 7-day follow-up) and then categorized into four groups: true positive, false positive, true negative, and false negative. These results lead to four categorical values. From these results, sensitivity, specificity, positive predictive value, negative predictive value, and likelihood ratios were calculated. RESULTS There were 5 (12%) true positives, 1 (2%) false positive, 37 (86%) true negatives, and zero (0%) false negative. The SSLOW was 100% sensitive (95% CI 5-100%) and 97% specificity (95% CI 74-96%). There was an 80% positive predictive value (95% CI 1.0-64% 95% CI) and 100% negative predictive value (95% CI 88-100%). The positive likelihood ratio was 8.4 (95% CI 3.69-19.1) and negative likelihood ratio was 0. CONCLUSION The SSLOW examination may be a useful tool in the evaluation of penetrating abdominal injuries.

Abstract
Flat inferior vena cava (IVC) on ultrasound examination has been shown to correlate with hypovolemic status. We hypothesize that a flat IVC on limited echocardiogram (LTTE) performed in the emergency room (ER) correlates with poor prognosis in acutely ill surgical patients. We conducted a retrospective review of all patients undergoing LTTE in the ER from September 2010 until June 2011. IVC diameter was estimated by subxiphoid window. Flat IVC was defined as diameter less than 2 cm. Fat IVC was defined as diameter greater than 2 cm. Need for intensive care unit admission, blood transfusion requirement, mortality, and need for emergent operation between patients with flat versus Fat IVC were compared. One hundred one hypotensive patients had LTTE performed in the ER. Average age was 38 years. Admission diagnosis was blunt trauma (n = 80), penetrating trauma (n = 13), acute care surgery pathology (n = 7), and burn (n = 1). Seventy-four patients had flat IVC on initial LTTE. Compared with those with fat IVC, flat patients were found have higher rates of intensive care unit admission (51.3 vs 14.8%; P = 0.001), blood transfusion requirement (12.2 vs 3.7%), and mortality (13.5 vs 3.7%). This population also underwent emergent surgery on hospital Day 1 more often (16.2 vs 0%; P = 0.033). Initial flat IVC on LTTE is an indicator of hypovolemia and a predictor of poor outcome.

Abstract
The extended focused assessment with sonography for trauma (eFAST) ultrasound examination is an essential step in the initial assessment of trauma patients. Its accuracy depends on the ability to acquire high-quality ultrasound images, and we hypothesized that increasing BMI was associated with increased odds for incorrect eFAST. All adult blunt trauma activations at a high-volume urban trauma center in 2016 that underwent eFAST and CT chest, abdomen, and pelvis were included (n = 446). Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the eFAST were calculated with CT results as reference. The association of BMI and eFAST accuracy was determined using univariate analyses. Sensitivity and specificity of the eFASTexamination were 27.1 per cent and 91.7 per cent, respectively, with an overall 76.2 per cent accuracy. At BMI 36 kg/m2, the odds of having incorrect eFAST results increased to odds ratio (OR) = 1.85 (95% confidence interval, 1.03–3.32; P = 0.05). For those with BMI > 40 kg/m2, the OR increased to OR = 3.12 (95% confidence interval, 1.45–6.69; P = 0.01). One-third of patients in this study were obese or morbidly obese. The latter was associated with increased odds for incorrect eFAST results, particularly the abdominal examination component.

Abstract
Use of bedside ultrasonography to identify life-threatening injuries for patients with blunt and penetrating trauma is the standard of care in the emergency department. The "FAST" examination-focused assessment with sonography for trauma-ultrasound scan of the chest and abdomen allows clinicians to assess critical regions for free fluid without use of invasive procedures as quickly and as often as needed. In addition, ultrasonography has a high degree of sensitivity and specificity and is safe during pregnancy. For patients requiring evaluation of the pleura, the "eFAST" (or extended FAST) may be conducted, which may serve to locate pleural effusions, hemothorax, and pneumothorax. However, ultrasound quality is operator dependent and is recommended with other diagnostic measures to provide a complete clinical picture of trauma patients. Ongoing development of ultrasound competency among established clinicians and nurse practitioner students is vital to maintain diagnostic accuracy and ensure quality care for trauma patients in the emergency department.

Abstract
The use of point-of-care sonography in clinical settings such as emergency medicine and intensive care units has increased, but adoption in neonatology has been slow. Unlike the focused assessment with sonography for trauma scan used in adults, a quick bedside scan to rapidly evaluate an acutely deteriorating neonate does not exist. The objective of our article is to introduce a focused bedside ultrasound scan that is easy to learn, rapidly performed, and relatively inexpensive.© 2018 by the American Institute of Ultrasound in Medicine.

Abstract
This article in our point-of-care ultrasound (PoCUS) series is dedicated to the role the focused assessment with sonography in trauma (FAST) exam plays for the regional anesthesiologist and pain specialists in the perioperative setting. The FAST exam is a well-established and extensively studied PoCUS exam in both surgical and emergency medicine literature with over 20 years demonstrating its benefit in identifying the presence of free fluid in the abdomen following trauma. However, only recently has the FAST exam been shown to be beneficial to the anesthesiologist in the perioperative setting as a means to identify the extravasation of free fluid into the abdomen from the hip joint following hip arthroscopy. In this article, we will describe how to obtain the basic FAST views (subcostal four-chamber view, perihepatic right upper quadrant view, perisplenic left upper quadrant view, and pelvic view in the longitudinal and short axis) as well as cover the relevant sonoanatomy. We will describe pathological findings seen with the FAST exam, primarily free fluid in the peritoneal space as well as in the pericardial sac. As is the case with any PoCUS skill, the application evolves with understanding and utilization by new clinical specialties. Although this article will provide clinical examples of where the FAST exam is beneficial to the regional anesthesiologist and pain specialist, it also serves as an introduction to this powerful PoCUS skill in order to encourage clinical practitioners to expand the application of the FAST exam within the scope of regional anesthesia and pain management practice.

Abstract
OBJECTIVES The purpose of this study was to conduct a systematic review of the evidence of educational outcomes associated with teaching ultrasonography (US) to medical students. METHODS A review of databases through 2016 was conducted for research studies that reported data on teaching US to medical students. Each title and abstract were reviewed by teams of 2 independent abstractors to determine whether the article would be ordered for full-text review and subsequently by 2 independent authors for inclusion. Data were abstracted with a form developed a priori by the authors. RESULTS Ninety-five relevant unique articles were included (of 6936 identified in the databases). Survey data showed that students enjoyed the US courses and desired more US training. Of the studies that assessed US-related knowledge and skill, most of the results were either positive (16 of 25 for knowledge and 24 of 58 for skill) or lacked a control (8 of 25 for knowledge and 27 of 58 for skill). The limited evidence (14 of 95 studies) of the effect of US training on non-US knowledge and skill (eg, anatomy knowledge or physical examination skill) was mixed. CONCLUSIONS There is ample evidence that students can learn US knowledge and skills and that they enjoy and want US training in medical school. The evidence for the effect of US on external outcomes is limited, and there is insufficient evidence to recommend it for this purpose at this time.

Abstract
PURPOSE Wrist has a complex anatomy and undergoes complex injuries. Scaphoid fracture is one of such injuries. It is the most common fracture in carpal bone. Most of the scaphoid fractures are missed on initial X-rays. Magnetic resonance imaging (MRI) is considered as a gold standard for diagnosing scaphoid fractures. Ultrasonography (USG) is emerging as a good alternative to make an early diagnosis of scaphoid fractures. Our aim is to throw light upon the role of USG in detection of scaphoid fractures. METHODS The study was centered upon 114 patients in the age range 10-65 years, with traumatic wrist injury and were clinically suspected to have scaphoid fractures. Patient with non-traumatic history, bilateral wrist injury and late presentation were excluded. X-rays, USG using high frequency probe and MRI were done for all patients. MRI was considered to be the gold standard test. Patients were followed up at 6 weeks. RESULTS Of the 114 patients, X-ray could diagnose scaphoid fractures in 48 patients, 30 of which were confirmed by MRI. USG results were positive in 74 patients, of which MRI was positive in 67 patients. The accuracy of scaphoid fracture detection with USG was 98.04% in comparison to X-ray (20.58%), which was statistically significant. CONCLUSION USG provides a more accurate and reliable method of making an early diagnosis of scaphoid fracture than X-rays. It is non-invasive, non-expensive and allows better visualisation of cortical disruption.

Abstract
To stabilize critically ill patients, emergency and critical care medicine providers often require rapid diagnosis and intervention. The demand for a safe, timely diagnostic device, alongside technological innovation, led to the advent of point-of-care ultrasonography (POCUS). POCUS allows the provider to gain invaluable clinical information with a high level of accuracy, leading to better clinical decision-making and improvements in patient safety. We have outlined the history of POCUS adaptation in emergency and critical care medicine and various clinical applications of POCUS described in literature.

Abstract
BACKGROUND Conventional echocardiographic technique for assessment of volume status and cardiac contractility utilizes left ventricular end-diastolic area (LVEDA) and fractional area of change (FAC), respectively. Our goal was to find a technically reliable yet faster technique to evaluate volume status and contractility by measuring left ventricular end-diastolic diameter (LVEDD) and fractional shortening (FS) in a cohort of mechanically ventilated trauma and burn patients using hemodynamic transesophageal echocardiographic (hTEE) monitoring. METHODS Retrospective chart review performed at trauma/burn intensive care unit (TBICU). Data on 88 mechanically ventilated surgical intensive care patients cared for between July 2013 and July 2015 were reviewed. Initial measurements of LVEDA, left ventricular end-systolic area (LVESA) and FAC were collected. Post-processing left ventricular end-systolic (LVESD) and end-diastolic diameters (LVEDD) were measured and fractional shortening (FS) was calculated. Two orthogonal measurements of LV diameter were obtained in transverse (Tr) and posteroanterior (PA) orientation. RESULTS There was a significant correlation between transverse and posteroanterior left ventricular diameter measurements in both systole and diastole. In systole, r = 0.92, p < 0.01 for LVESD-Tr (mean 23.47 mm, SD ± 6.77) and LVESD-PA (mean 24.84 mm, SD = 8.23). In diastole, r = 0.80, p < 0.01 for LVEDD-Tr (mean 37.60 mm, SD ± 6.45), and LVEDD-PA diameters (mean 42.24 mm, SD ± 7.97). Left ventricular area (LVEDA) also significantly correlated with left ventricular diameter LVEDD-Tr (r = 0.84, p < 0.01) and LVEDD-PA (r = 0.90, p < 0.01). Both transverse and PA measurements of fractional shortening were significantly (p < 0.0001) and similarly correlated with systolic function as measured by FAC. Bland-Altman analyses also indicated that the assessment of fractional shortening using left ventricular posteroanterior diameter measurement shows agreement with FAC. CONCLUSIONS Left ventricular diameter measurements are a reliable and technically feasible alternative to left ventricular area measurements in the assessment of cardiac filling and systolic function.

Abstract
OBJECTIVE To report the outcomes over 14 years of sustained systematic institutional focus on the care of women with major obstetric hemorrhage, defined as estimated blood loss greater than 1,500 mL. METHODS A retrospective cohort study of women with major obstetric hemorrhage at our hospital from 2000 to 2014 compares baseline conditions (age, multiparity, prior cesarean delivery, morbidly adherent placenta), morbidity (lowest mean temperature, lowest mean pH, coagulopathy, hysterectomy), and mortality among three time periods (period 1=January 2000 to December 2001, period 2=January 2002 to August 2005, period 3=September 2005 to December 2014). We also describe the systematic changes that helped to sustain our improved outcomes. RESULTS During the three time periods, there were 5,811, 12,912, and 38,971 births; the rate of major obstetric hemorrhage increased over these periods: 2.1, 3.8 and 5.3 cases per 1,000 births, respectively. Two deaths from hemorrhage occurred in period 1 and none thereafter. Among women who experienced massive hemorrhage, morbidity significantly improved in each successive period: median lowest pH increased from 7.23 to 7.34 to 7.35 (periods 2 and 3 significantly higher than period 1), median lowest maternal temperature (°C) improved, 35.2 to 36.1 to 36.4 (all difference significant), and the rate of coagulopathy decreased, 58.3% to 28.6% to 13.2% (period 3 significantly lower than periods 1 and 2) (all P values <.001). Peripartum hysterectomies were more frequent and more frequently planned over time rather than urgent in each successive period: 0 of 6 to 6 of 18 (33%) to 31 of 64 (48.4%) (P=.044). During period 3, we reorganized the obstetric rapid response team, instituted a massive transfusion protocol and use of uterine balloon tamponade, and promoted a culture of safety in two ways-through more intensive education regarding hemorrhage and escalation (encouraging all staff to contact senior leaders). CONCLUSION A sustained level of patient safety is achievable when treating major obstetric hemorrhage, as shown by a progressive decrease in morbidity despite increasing rates of hemorrhage.

Abstract
OBJECTIVE Focused ultrasound (US) is being incorporated across all levels of medical education. Although many comprehensive US courses exist, their scope is broad, requiring expert instructors, access to simulation, and extensive time commitment by the learner. We aim to compare learning across levels of training and specialties using a goal-directed, web-based course without live skills training. DESIGN A prospective observational study of students and residents from medicine, surgery, and anesthesiology. Analysis compared pretests and posttests assessing 3 competencies. Individual mean score improvement (MSI) was compared by paired-sample t-tests and MSI among cohorts by analysis of variance, with significance set at p ≤ 0.05. McNemar test compared those who agreed or strongly agreed with survey items with those who did not before and after intervention. SETTING Jackson Memorial Hospital, Miami, FL residency training programs in Medicine, Surgery, and Anesthesiology. RESULTS A total of 180 trainees participated. A significant MSI was noted in each of 3 competencies in all 3 cohorts. Students' (S) MSI was significantly higher than residents' (R) and interns' (I) in US "knobology" and window recognition [S = 2.28 ± 1.29/5 vs R = 1.63 ± 1.21/5 (p = 0.014); vs I = 1.59 ± 1.12/5 (p = 0.032)]; students' total score MSI was significantly higher than residents [7.60 ± 3.43/20 vs 5.78 ± 3.08/20 (p < 0.008)]. All cohorts reported improved comfort in using transthoracic US and improved ability to recognize indications for use. More than 81% of all participants reported improved confidence in performing transthoracic US; more than 91% reported interest in additional training; and more than 88% believed course length was appropriate. CONCLUSIONS Learners across levels of medical training and specialties can benefit from a brief, goal-directed, web-based training with early incorporation producing maximal yield.

Abstract
IMPORTANCE The utility of the focused assessment with sonography for trauma (FAST) examination in children is unknown. OBJECTIVE To determine if the FAST examination during initial evaluation of injured children improves clinical care. DESIGN, SETTING, AND PARTICIPANTS A randomized clinical trial (April 2012-May 2015) that involved 975 hemodynamically stable children and adolescents younger than 18 years treated for blunt torso trauma at the University of California, Davis Medical Center, a level I trauma center. INTERVENTIONS Patients were randomly assigned to a standard trauma evaluation with the FAST examination by the treating ED physician or a standard trauma evaluation alone. MAIN OUTCOMES AND MEASURES Coprimary outcomes were rate of abdominal computed tomographic (CT) scans in the ED, missed intra-abdominal injuries, ED length of stay, and hospital charges. RESULTS Among the 925 patients who were randomized (mean [SD] age, 9.7 [5.3] years; 575 males [62%]), all completed the study. A total of 50 patients (5.4%, 95% CI, 4.0% to 7.1%) were diagnosed with intra-abdominal injuries, including 40 (80%; 95% CI, 66% to 90%) who had intraperitoneal fluid found on an abdominal CT scan, and 9 patients (0.97%; 95% CI, 0.44% to 1.8%) underwent laparotomy. The proportion of patients with abdominal CT scans was 241 of 460 (52.4%) in the FAST group and 254 of 465 (54.6%) in the standard care-only group (difference, -2.2%; 95% CI, -8.7% to 4.2%). One case of missed intra-abdominal injury occurred in a patient in the FAST group and none in the control group (difference, 0.2%; 95% CI, -0.6% to 1.2%). The mean ED length of stay was 6.03 hours in the FAST group and 6.07 hours in the standard care-only group (difference, -0.04 hours; 95% CI, -0.47 to 0.40 hours). Median hospital charges were $46 415 in the FAST group and $47 759 in the standard care-only group (difference, -$1180; 95% CI, -$6651 to $4291). CONCLUSIONS AND RELEVANCE Among hemodynamically stable children treated in an ED following blunt torso trauma, the use of FAST compared with standard care only did not improve clinical care, including use of resources; ED length of stay; missed intra-abdominal injuries; or hospital charges. These findings do not support the routine use of FAST in this setting. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT01540318.

Whole body CT versus selective radiological imaging strategy in trauma: an evidence-based clinical review. Am J Emerg Med 2017; 35:1356-1362. [PMID: 28366287 DOI: 10.1016/j.ajem.2017.03.048] [Citation(s) in RCA: 41] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2017] [Revised: 03/19/2017] [Accepted: 03/21/2017] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND Trauma patients often present with injuries requiring resuscitation and further evaluation. Many providers advocate for whole body computed tomography (WBCT) for rapid and comprehensive diagnosis of life-threatening injuries. OBJECTIVE Evaluate the literature concerning mortality effect, emergency department (ED) length of stay, radiation, and incidental findings associated with WBCT. DISCUSSION Physicians have historically relied upon history and physical examination to diagnose life-threatening injuries in trauma. Diagnostic imaging modalities including radiographs, ultrasound, and computed tomography have demonstrated utility in injury detection. Many centers routinely utilize WBCT based on the premise this test will improve mortality. However, WBCT may increase radiation and incidental findings when used without considering pre-test probability of actionable traumatic injuries. Studies supporting WBCT are predominantly retrospective and incorporate trauma scoring systems, which have significant design weaknesses. The recent REACT-2 trial randomized trauma patients with high index of suspicion for actionable injuries to WBCT versus selective imaging and found no mortality difference. Additional prospective trials evaluating WBCT in specific trauma subgroups (e.g. polytrauma) are needed to evaluate benefit. In the interim, the available data suggests clinicians should adopt a selective imaging strategy driven by history and physical examination. CONCLUSIONS While observational data suggests an association between WBCT and a benefit in mortality and ED length of stay, randomized controlled data suggests no mortality benefit to this diagnostic tool. The literature would benefit from confirmatory studies of the use of WBCT in trauma sub-groups to clarify its impact on mortality for patients with specific injury patterns.

Abstract
The utility of point-of-care ultrasound is well supported by the medical literature. Consequently, pediatric emergency medicine providers have embraced this technology in everyday practice. Recently, the American Academy of Pediatrics published a policy statement endorsing the use of point-of-care ultrasound by pediatric emergency medicine providers. To date, there is no standard guideline for the practice of point-of-care ultrasound for this specialty. This document serves as an initial step in the detailed "how to" and description of individual point-of-care ultrasound examinations. Pediatric emergency medicine providers should refer to this paper as reference for published research, objectives for learners, and standardized reporting guidelines.

Abstract
BACKGROUND Traditionally, ultrasound has been used to evaluate musculoskeletal injuries in athletes; however, ultrasound applications extend well beyond musculoskeletal conditions, many of which are pertinent to athletes. EVIDENCE ACQUISITION Articles were identified in PubMed using the search terms ultrasound, echocardiogram, preparticipation physical examination, glycogen, focused assessment with sonography of trauma, optic nerve, and vocal cord dysfunction. No date restrictions were placed on the literature search. STUDY DESIGN Clinical review. LEVEL OF EVIDENCE Level 4. RESULTS Several potential applications of nonmusculoskeletal ultrasound in sports medicine are presented, including extended Focused Assessment with Sonography for Trauma (eFAST), limited echocardiographic screening during preparticipation physical examinations, assessment of muscle glycogen stores, optic nerve sheath diameter measurements in athletes with increased intracranial pressure, and assessment of vocal cord dysfunction in athletes. CONCLUSION Ultrasound can potentially be used to assist athletes with monitoring their muscle glycogen stores and the diagnosis of multiple nonmusculoskeletal conditions within sports medicine.

Abstract
Hypotension is a common endpoint to many disease processes and can be evaluated with ultrasonography at the bedside. This ultrasound protocol can be used to examine the key organs involved in maintaining a blood pressure and the areas within the torso where fluid can collect. Systematically investigating these areas can provide the health care team with key information concerning the hypotensive state. This protocol examines the torso from the geometric perspective of a cross (Trinity).

Abstract
Metabolic sugar labeling followed by the use of reagent-free click chemistry is an established technique for in vitro cell targeting. However, selective metabolic labeling of the target tissues in vivo remains a challenge to overcome, which has prohibited the use of this technique for targeted in vivo applications. Herein, we report the use of targeted ultrasound pulses to induce the release of tetraacetyl N-azidoacetylmannosamine (Ac4 ManAz) from microbubbles (MBs) and its metabolic expression in the cancer area. Ac4 ManAz-loaded MBs showed great stability under physiological conditions, but rapidly collapsed in the presence of tumor-localized ultrasound pulses. The released Ac4 ManAz from MBs was able to label 4T1 tumor cells with azido groups and significantly improved the tumor accumulation of dibenzocyclooctyne (DBCO)-Cy5 by subsequent click chemistry. We demonstrated for the first time that Ac4 ManAz-loaded MBs coupled with the use of targeted ultrasound could be a simple but powerful tool for in vivo cancer-selective labeling and targeted cancer therapies.

Abstract
Ultrasound in the emergency department has long been recognized as a powerful screening and diagnostic tool for both physicians and radiologists. In the emergency department, since time is of the essence, it becomes a critical tool in triaging patients. Over the years, ultrasound has gained several advantages over other modalities because of its non-ionizing radiation, portability, accessibility, non-invasive method and simpler learning curve. As a result, ultrasound has become one of the most frequently used diagnostic tools in the emergency department by non-radiologists. The value of ultrasound is implemented in every acute ailment in the emergency department such as trauma, acute abdomen, acute pelvic pain, acute scrotal pain, appendicitis in children and acute deep venous thrombosis. Our objective is to discuss the benefit of using ultrasound as the primary modality for each of these diseases.

Abstract
Ultrasound is a standard adjunct to the initial evaluation of injured patients in the emergency department. We sought to evaluate the ability of prehospital, in-flight thoracic ultrasound to identify pneumothorax. Non-physician aeromedical providers were trained to perform and interpret thoracic ultrasound. All adult trauma patients and adult medical patients requiring endotracheal intubation underwent both in-flight and emergency department ultrasound evaluations. Findings were documented independently and reviewed to ensure quality and accuracy. Results were compared to chest X-ray and computed tomography (CT). One hundred forty-nine patients (136 trauma/13 medical) met inclusion criteria. Mean age was 44.4 (18-94) years; 69 % were male. Mean injury severity score was 17.68 (1-75), and mean chest injury score was 2.93 (0-6) in the injured group. Twenty pneumothoraces and one mainstem intubation were identified. Sixteen pneumothoraces were correctly identified in the field. A mainstem intubation was misinterpreted. When compared to chest CT (n = 116), prehospital ultrasound had a sensitivity of 68 % (95 % confidence interval (CI) 46-85 %), a specificity of 96 % (95 % CI 90-98 %), and an overall accuracy of 91 % (95 % CI 85-95 %). In comparison, emergency department (ED) ultrasound had a sensitivity of 84 % (95 % CI 62-94 %), specificity of 98 % (95 % CI 93-99 %), and an accuracy of 96 % (95 % CI 90-98 %). The unique characteristics of the aeromedical environment render the auditory element of a reliable physical exam impractical. Thoracic ultrasonography should be utilized to augment the diagnostic capabilities of prehospital aeromedical providers.

Abstract
OBJECTIVE Point-of-care ultrasound (POCUS) is a vital tool for diagnosis and management of critically ill patients, particularly in resource-limited settings where access to diagnostic imaging may be constrained. We aimed to develop a novel POCUS training curriculum for surgical practice in the United States and in resource-limited settings in low- and middle-income countries and to determine its effect on surgical resident self-assessments of efficacy and confidence. DESIGN We conducted an observational cohort study evaluating a POCUS training course that comprised 7 sessions of 2 hours each with didactics and proctored skills stations covering ultrasound applications for trauma (Focused Assessement with Sonography for Trauma (FAST) examination), obstetrics, vascular, soft tissue, regional anesthesia, focused echocardiography, and ultrasound guidance for procedures. Surveys on attitudes, prior experience, and confidence in point-of-care ultrasound applications were conducted before and after the course. SETTING General Surgery Training Program in Seattle, Washington. PARTICIPANTS A total of 16 residents participated in the course; 15 and 10 residents completed the precourse and postcourse surveys, respectively. RESULTS The mean composite confidence score from pretest compared with posttest improved from 23.3 (±10.2) to 37.8 (±6.7). Median confidence scores (1-6 scale) improved from 1.5 to 5.0 in performance of FAST (p < 0.001). Residents reported greater confidence in their ability to identify pericardial (2 to 4, p = 0.009) and peritoneal fluid (2 to 4.5, p < 0.001), to use ultrasound to guide procedures (3.5 to 4.0, p = 0.008), and to estimate ejection fraction (1 to 4, p = 0.004). Both before and after training, surgical residents overwhelmingly agreed with statements that ultrasound would improve their US-based practice, make them a better surgical resident, and improve their practice in resource-limited settings. CONCLUSIONS After a POCUS course designed specifically for surgeons, surgical residents had improved self-efficacy and confidence levels across a broad range of skills.

Abstract
Emergency physician (EP)-performed focused cardiac ultrasound (EP FOCUS) has been increasingly recognized as a crucial tool to help clinicians diagnose and treat potentially life-threatening conditions. The existing literature demonstrates a variety of EP FOCUS applications and protocols; however, EP FOCUS is not taught, practiced, or interpreted consistently between institutions. Drawing on over 12 years of experience in a large-volume, high-acuity academic emergency department, we have developed a protocol for teaching and performing EP FOCUS known as "The 5Es," where each E represents a specific assessment for immediately relevant clinical information. These include pericardial effusion, qualitative left ventricular ejection, ventricular equality, exit (aortic root diameter), and entrance (inferior vena cava diameter and respirophasic variation). Each of these assessments has been well described in the emergency medicine literature and is within the scope of EP-performed echocardiography. This approach provides a reliable and easily recalled framework for assessing, teaching, and communicating EP FOCUS findings that are essential in caring for the patient in the emergency setting.

Abstract
OBJECTIVE Despite great prevention efforts, blunt abdominal trauma still remains a leading cause of injury, especially in the paediatric population. Abdominal trauma is the main culprit of serious children's injury and the most common area of initially missed diagnosis with a fatal outcome. AIM The purpose of this study was to determine the incidence, aetiology, grades of abdominal organ injuries, diagnosis, management and outcome of blunt abdominal trauma in a paediatric population. METHOD This is a retrospective study of 31 patients with isolated parenchymatous abdominal organs, treated in a single centre. Stable patients with no signs of peritonitis and insignificant changes in laboratory findings were managed conservatively. Unstable patients received surgery. RESULTS The leading cause of injuries were traffic accidents (64.5%), followed by fall from a height (22.5%), bicycle handlebar injuries (6.45%), contact sport and child abuse (3.22% each). The majority of injured children (90.32%) were managed conservatively. Only three patients (9.68%) were operated on due to complete avulsion and organ smash, or devascularization of the injured organs. Diagnostic computed tomography (CT) scan examination was performed on 93.5% of patients. Few patients had grade I and grade V injuries, while the largest proportion of patients had grade III and IV injuries. The most frequently injured organs were the spleen and kidney. There was no mortality. CONCLUSION The results emphasize that conservative treatment was appropriate for all stable patients with blunt abdominal trauma regardless of organ injury grade. The success of non-operative management depends upon proper patient selection. The choice of non-operative treatment should be based predominantly on physiological response, rather than grade injury on CT scan.

Abstract
BACKGROUND Trauma is the leading cause of death in people under the age of 45 years. Over the past 20 years, intraoperative autologous transfusions (obtained by cell salvage, also known as intraoperative blood salvage (IBS)) have been used as an alternative to blood products from other individuals during surgery because of the risk of transfusion-related infections such as hepatitis and human immunodeficiency virus (HIV). In this review, we sought to assess the effects and cost of cell salvage in individuals undergoing abdominal or thoracic surgery. OBJECTIVES To compare the effect and cost of cell salvage with those of standard care in individuals undergoing abdominal or thoracic trauma surgery. SEARCH METHODS We ran the search on 25 November 2014. We searched the Cochrane Injuries Group's Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), Ovid MEDLINE, Ovid MEDLINE In-Process & Other Non-Indexed Citations, Ovid MEDLINE Daily and Ovid OLDMEDLINE, EMBASE Classic + EMBASE (OvidSP), PubMed, and ISI Web of Science (SCI-Expanded & CPSI-SSH). We also screened reference lists and contacted principal investigators. SELECTION CRITERIA Randomised controlled trials comparing cell salvage with no cell salvage (standard care) in individuals undergoing abdominal or thoracic trauma surgery. DATA COLLECTION AND ANALYSIS Two authors independently extracted data from the trial reports. We used the standard methodological procedures expected by The Cochrane Collaboration. MAIN RESULTS Only one small study (n = 44) fulfilled the inclusion criteria. Results suggested that cell salvage did not affect mortality overall (death rates were 67% (14/21 participants) in the cell salvage group and 65% (15/23) in the control group) (odds ratio (OR) 1.07, 95% confidence interval (CI) 0.31 to 3.72). For individuals with abdominal injury, mortality was also similar in both groups (OR 0.48, 95% CI 0.11 to 2.10).Less donor blood was needed for transfusion within the first 24 hours postinjury in the cell salvage group compared with the control group (mean difference (MD) -4.70 units, 95% CI -8.09 to -1.31). Adverse events, notably postoperative sepsis, did not differ between groups (OR 0.54, 95% CI 0.11 to 2.55). Cost did not notably differ between groups (MD -177.81, 95% CI -452.85 to 97.23, measured in GBP in 2002). AUTHORS' CONCLUSIONS Evidence for the use of cell salvage in individuals undergoing abdominal or thoracic trauma surgery remains equivocal. Large, multicentre, methodologically rigorous trials are needed to assess the relative efficacy, safety and cost-effectiveness of cell salvage in different surgical procedures in the emergency context.

Abstract
BACKGROUND AND AIMS The objective was to determine the sensitivity and specificity of Focused Assessment with Sonography for Trauma (FAST) in patients with confirmed liver lesions and also to compare results from surgeons trained in FAST with results from radiologists trained in general abdominal ultrasound as part of the specialist training. Explorative laparotomy or CT served as gold standard. MATERIALS AND METHODS This retrospective study included all patients admitted to our institution from 2003 to 2010 registered with the diagnosis "Injury of the liver or gallbladder". Of 405 patients, 135 patients were eligible for analysis. Seventy-two patients were examined by radiologists and 63 by surgeons. RESULTS We found FAST to have a sensitivity, specificity, PPV, and NPV of 79.6%, 100%, 100%, and 68.9%. There was no statistically significant difference between FAST performed by radiologists and surgeons trained in FAST. CONCLUSION FAST remains an important screening tool in abdominal trauma including liver lesions, and can be performed at a satisfactory level by surgeons trained in the FAST procedure only.

Abstract
BACKGROUND The aim of this study was to systematically review the different methods for training Focused Assessment Sonography for Trauma (FAST), course design, and requirements for hospital credentialing. METHODS We searched MEDLINE/PubMed, EMBASE, and the Cochrane database and performed a manual search of selected papers. All papers and abstracts written in English that studied training and education of FAST were included. Papers were critically evaluated, looking into training methods and models of FAST, their advantages and disadvantages, number and type of training hours, practice exams in the course, and number of cases advised to achieve hospital credentialing. RESULTS A total of 52 studies were critically analyzed. The theoretical part of the courses lasted over a median (range) of 4 (1-16) h (n = 35 studies), while the practical part lasted over a median (range) of 4 (1-32) h (n = 34 studies). The participants performed a median (range) of 10 (3-20) FAST exams during the courses (n = 13 studies). The most commonly used model was the normal human model (65 %), followed by peritoneal dialysis patients (27 %). The least used models were animal (4 %) and cadaveric models (2 %). Each of these models had their advantages and disadvantages. The median number (range) of FAST exams needed for credentialing was 50 (10-200) (n = 19 studies). CONCLUSION Standardization of FAST training is important to improving the clinical impact of FAST. Different models used in FAST training are complementary; each has its own advantages and disadvantages. It is recommended that FAST courses be at least 2 days (16 h) long. The first day should include 4 h of theory and 4 h of training on normal human models. The second day should enforce learning using animal models, case scenarios including video clips, or simulators.

Abstract
BACKGROUND Ultrasonography is increasingly used by clinicians to identify abdominal aortic aneurysms (AAA). We performed a systematic review and meta-analysis comparing the accuracy of non-radiologist performed ultrasound (NRPUS) for AAA disease to the 'gold standard' of radiologist performed aortic imaging (RPI), intra-operative findings or postmortem findings. METHODS Cochrane Library, MEDLINE, EMBASE, SCOPUS-V.4, trial registries, conference proceedings, and article reference lists were searched to identify studies comparing NRPUS with RPI as the reference standard. Data abstracted from eligible studies was used to generate 2 × 2 contingency tables allowing calculation of pooled sensitivity and specificity values. RESULTS 11 studies (944 patients) evaluated NRPUS for AAA detection. NRPUS had a pooled sensitivity of 0.975 [95% confidence interval (CI), 0.942-0.992] for AAA detection and a pooled specificity of 0.989 (95% CI, 0.979-0.995). CONCLUSIONS Non-radiologist performed ultrasound achieves acceptable sensitivity and specificity for both detection and measurement of AAA. There was no evidence of significant heterogeneity with respect to pooled sensitivity or specificity.

Abstract
Background: In stable patients with blunt abdominal trauma, accurate diagnosis of visceral injuries is crucial. Objectives: To determine whether repeating ultrasound exam will increase the sensitivity of focused abdominal sonography for trauma (FAST) through revealing additional free intraperitoneal fluid in patients with blunt abdominal trauma. Patients and Methods: We performed a prospective observational study by performing primary and secondary ultrasound exams in blunt abdominal trauma patients. All ultrasound exams were performed by four radiology residents who had the experience of more than 400 FAST exams. Five routine intraperitoneal spaces as well as the interloop space were examined by ultrasound in order to find free fluid. All patients who expired or were transferred to the operating room before the second exam were excluded from the study. All positive ultrasound results were compared with intra-operative and computed tomography (CT) findings and/or the clinical status of the patients. Results: Primary ultrasound was performed in 372 patients; 61 of them did not undergo secondary ultrasound exam; thus, were excluded from the study.Three hundred eleven patients underwent both primary and secondary ultrasound exams. One hundred and two of all patients were evaluated by contrast enhanced CT scan and 31 underwent laparotomy. The sensitivity of ultrasound exam in detecting intraperitoneal fluid significantly increased from 70.7% for the primary exam to 92.7% for the secondary exam. Examining the interloop space significantly improved the sensitivity of ultrasonography in both primary (from 36.6% to 70.7%) and secondary (from 65.9% to 92.7%) exams. Conclusions: Performing a secondary ultrasound exam in stable blunt abdominal trauma patients and adding interloop space scan to the routine FAST exam significantly increases the sensitivity of ultrasound in detecting intraperitoneal free fluid.

Abstract
AbstractObjective:To assess the feasibility and accuracy of otolaryngologist-performed ultrasound in evaluating head and neck pathology.Method:An ENT trainee, who had undergone basic training in neck ultrasonography, performed this on patients referred with suspected neck pathology. The trainee recorded the presence and nature of any abnormality. Findings were compared with those from a repeated scan performed by an experienced head and neck radiologist.Results:The study included 250 patients. The absence or presence of lesion as reported by the trainee correlated with the radiologist's findings in 207 cases (83 per cent). There were 144 true positives, 63 true negatives, 32 false negatives and 11 false positives, yielding a sensitivity of 82 per cent, specificity of 85 per cent and accuracy of 83 per cent. Of the 144 true positive lesions, 81 per cent were interpreted concordantly with the radiologist.Conclusion:Neck ultrasonography performed by an otolaryngologist is less accurate than that performed by an experienced radiologist, but is still a useful adjunct to clinical assessment, facilitating assessment in a ‘one-stop’ clinical setting.
