Abstract
OBJECTIVE Focused assessment with sonography for trauma (FAST) is a valuable ultrasound procedure in emergency settings, and there is a need for evidence-based education in FAST to ensure competencies. Immersive virtual reality (IVR) is a progressive training modality gaining traction in the field of ultrasound training. IVR holds several economic and practical advantages to the common instructor-led FAST courses using screen-based simulation (SBS). METHODS This prospective, interventional cohort study investigated whether training FAST using IVR unsupervised and out-of-hospital was non-inferior to a historical control group training at a 90 min SBS course in terms of developing FAST competencies in novices. Competencies were assessed in both groups using the same post-training simulation-based FAST test with validity evidence, and a non-inferiority margin of 2 points was chosen. RESULTS A total of 27 medical students attended the IVR course, and 27 junior doctors attended the SBS course. The IVR group trained for a median time of 117 min and scored a mean 14.2 ± 2.0 points, compared with a mean 13.7 ± 2.5 points in the SBS group. As the lower bound of the 95% confidence interval at 13.6 was within the range of the non-inferiority margin (11.7-13.7 points), training FAST in IVR for a median of 117 min was found non-inferior to training at a 90 min SBS course. No significant correlation was found between time spent in IVR and test scores. CONCLUSION Within the limitations of the use of a historical control group, the results suggest that IVR could be an alternative to SBS FAST training and suitable for unsupervised, out-of-hospital courses in basic FAST competencies.

Abstract
PURPOSE In the prehospital care of potentially seriously injured patients resource allocation adapted to injury severity (triage) is a challenging. Insufficiently specified triage algorithms lead to the unnecessary activation of a trauma team (over-triage), resulting in ineffective consumption of economic and human resources. A prehospital trauma triage algorithm must reliably identify a patient bleeding or suffering from significant brain injuries. By supplementing the prehospital triage algorithm with in-hospital established point-of-care (POC) tools the sensitivity of the prehospital triage is potentially increased. Possible POC tools are lactate measurement and sonography of the thorax, the abdomen and the vena cava, the sonographic intracranial pressure measurement and the capnometry in the spontaneously breathing patient. The aim of this review was to assess the potential and to determine diagnostic cut-off values of selected instrument-based POC tools and the integration of these findings into a modified ABCDE based triage algorithm. METHODS A systemic search on MEDLINE via PubMed, LIVIVO and Embase was performed for patients in an acute setting on the topic of preclinical use of the selected POC tools to identify critical cranial and peripheral bleeding and the recognition of cerebral trauma sequelae. For the determination of the final cut-off values the selected papers were assessed with the Newcastle-Ottawa scale for determining the risk of bias and according to various quality criteria to subsequently be classified as suitable or unsuitable. PROSPERO Registration: CRD 42022339193. RESULTS 267 papers were identified as potentially relevant and processed in full text form. 61 papers were selected for the final evaluation, of which 13 papers were decisive for determining the cut-off values. Findings illustrate that a preclinical use of point-of-care diagnostic is possible. These adjuncts can provide additional information about the expected long-term clinical course of patients. Clinical outcomes like mortality, need of emergency surgery, intensive care unit stay etc. were taken into account and a hypothetic cut-off value for trauma team activation could be determined for each adjunct. The cut-off values are as follows: end-expiratory CO2: < 30 mm/hg; sonography thorax + abdomen: abnormality detected; lactate measurement: > 2 mmol/L; optic nerve diameter in sonography: > 4.7 mm. DISCUSSION A preliminary version of a modified triage algorithm with hypothetic cut-off values for a trauma team activation was created. However, further studies should be conducted to optimize the final cut-off values in the future. Furthermore, studies need to evaluate the practical application of the modified algorithm in terms of feasibility (e.g. duration of application, technique, etc.) and the effects of the new algorithm on over-triage. Limiting factors are the restriction with the search and the heterogeneity between the studies (e.g. varying measurement devices, techniques etc.).

Abstract
Vascular injuries and hemorrhaging are serious potential complications in the management of patients with blunt abdominal trauma. The treatment depends on the extent and localization and can range from surveillance to endovascular treatment up to open surgery. The keys to success include the focused assessment with sonography for trauma (FAST) management and timely decision making. Abdominal vascular trauma continues to be a difficult problem and open and endovascular techniques continue to evolve in order to address this complex disease process.

Abstract
BACKGROUND Focused assessment sonography for trauma (FAST) performed in the prehospital setting may improve trauma care by influencing treatment decisions and reducing time to definitive care, but its accuracy and benefits remain uncertain. This systematic review evaluated the diagnostic accuracy of prehospital FAST in detecting hemoperitoneum and its effects on prehospital time and time to definitive diagnosis or treatment. METHODS We systematically searched PubMed, Embase, and Cochrane library up to November 11th, 2022. Studies investigating prehospital FAST and reporting at least one outcome of interest for this review were considered eligible. The primary outcome was prehospital FAST diagnostic accuracy for hemoperitoneum. A random-effect meta-analysis, including individual patient data, was performed to calculate the pooled outcomes with 95% confidence intervals (CI). Quality of studies was assessed using the QUADAS-2 tool for diagnostic accuracy. RESULTS We included 21 studies enrolling 5790 patients. The pooled sensitivity and specificity of prehospital FAST for hemoperitoneum were 0.630 (0.454 - 0.777) and 0.970 (0.957-0.979), respectively. Prehospital FAST was performed in a median of 2.72 (2.12 - 3.31) minutes without increasing prehospital times (pooled median difference of 2.44 min [95% CI: -3.93 - 8.81]) compared to standard management. Prehospital FAST findings changed on-scene trauma care in 12-48% of cases, the choice of admitting hospital in 13-71%, the communication with the receiving hospital in 45-52%, and the transfer management in 52-86%. Patients with a positive prehospital FAST achieved definitive diagnosis or treatment more rapidly (severity-adjusted pooled time ratio = 0.63 [95% CI: 0.41 - 0.95]) compared with patients with a negative or not performed prehospital FAST. CONCLUSIONS Prehospital FAST had a low sensitivity but a very high specificity to identify hemoperitoneum and reduced time-to-diagnostics or interventions, without increasing prehospital times, in patients with a high probability of abdominal bleeding. Its effect on mortality is still under-investigated.

Abstract
PURPOSE The purpose of this study is to report the relative accuracy of prehospital extended focused assessment with sonography in trauma (eFAST) examinations performed by HEMS physicians. METHODS Trauma patients who received prehospital eFAST by HEMS clinicians between January 2013 and December 2017 were reviewed. The clinician's interpretations of these ultrasounds were compared to gold standard references of CT imaging or operating room findings. The outcomes measured include the calculated accuracy of eFAST for detecting intraperitoneal free fluid (IPFF), pneumothorax, hemothorax, and pericardial fluid compared to available gold standard results. RESULTS Of the 411 patients with adequate data for comparison, the median age was 39.5 years with 73% male and 98% sustaining blunt force trauma. For the detection of IPFF, eFAST had a sensitivity of 25% (95% CI 16-36%) and specificity of 96% (95% CI 93-98%). Sensitivities and specificities were calculated for pneumothorax (38% and 96% respectively), hemothorax (17% and 97% respectively), and pericardial effusion (17% and 100% respectively). These results did not change significantly when reassessed with several sensitivity analyses. CONCLUSION Prehospital eFAST is reliable for detecting the presence of intraperitoneal free fluid. This finding should inform receiving trauma teams to prepare for early definitive care in these patients. The low sensitivities across all components of the eFAST highlight the importance of cautiously interpreting negative studies while prompting the need for further studies.

Abstract
Ultrasound is an important tool in diagnosis and treatment of critically ill patients. For trauma patients the eFAST (extended focused assessment with sonography for trauma) algorithm is already implemented in the diagnostic pathway. However, critically ill patients without trauma also need a structured approach including an early focused ultrasonographic exam. National and international guidelines regarding critical illnesses such as acute coronary syndrome, cardiogenic shock complicating myocardial infarction, pulmonary embolism or acute aortic syndromes recommend the use of ultrasound. We present pathways how ultrasound can be used in the diagnostic approach of common symptoms such as dyspnea, shock and abdominal pain. Using the ABCDE approach this article shows how ultrasound can be incorporated into the diagnostic pathway.

Abstract
Imaging forms a crucial component in reducing mortality of polytraumatized patients by aiding appropriate diagnosis and guiding the emergency and definitive treatment. With the exponential expansion in the radiological armamentarium and introduction of protocols like Extended focused assessment with sonography for trauma (EFAST) and Whole body Computed tomography (WBCT), the role of imaging has considerably increased. Emergency imaging protocols should be done for rapid diagnosis of life-threatening injuries allowing simultaneous evaluation and resuscitation. Subsequent comprehensive imaging is essential to diagnose the often clinically missed injuries to reduce the overall morbidity. Imaging protocols must adapt to the patient's clinical scenario, which can be dynamically changing. Each trauma team should devise clear guidelines, protocols, and algorithms suitable for their center depending on the local availability of types of equipment and expertise. Radiologists must efficiently communicate and adopt patient-centered approach to ensure early appropriate care to these severely injured patients. Future research should involve multicentre studies to formulate the most appropriate imaging protocol in polytrauma to increase diagnostic accuracy and thereby reduce patient mortality.

Abstract
PURPOSE Specific training in the management of trauma patients is beneficial for surgeons. Training through specific courses in this area has a direct impact on the care of these patients. The aim of this work is to understand the participation and specific training in the care of trauma patients by Spanish surgeons. METHODS A national survey was conducted and administered to all members of the Spanish Association of Surgeons. The survey assessed their degree of participation in emergency surgery, and therefore the probability of attending trauma patients, their assessment of the initial care of trauma patients in their centre, and their specific training in this field. RESULTS The survey was completed by 510 surgeons from 47 Spanish provinces, with Catalonia and Andalusia being the most represented regions. In total, 456 (89.41%) of those surveyed work in the emergency department on a routine basis. Only 171 (33.53%) refer to having a registry of trauma patients in their hospital. While 79.02% of surgeons reported that general surgeons are not involved in care of severe trauma from the outset, only 66.47% have completed the ATLS course, 40.78% the DSTC course and 18.82% the MUSEC course. Despite this, 85.69% believe that the ATLS course should be compulsory during residency and 43.33% believe that severe trauma care in their hospital is poor or very poor. CONCLUSION Only 40% have received specific training in definitive surgical management of severe trauma. Despite this, a large percentage of surgeons work in the emergency department on a routine basis and potentially face the challenge of managing these patients.

Abstract
Ultrasound is an important diagnostic tool in patients with abdominal pain and after injury. However, it is highly dependent on the skills and training of the examiner. Thus, ultrasound competencies should be acquired early during medical education. The instructional approach affects the retention and performance of skills. A promising approach is "mastery learning." The aim of the study was to evaluate the effectiveness of "mastery learning" compared with the "see one, do one" approach by performing a focused assessment of sonography for trauma (FAST) in undergraduate medical students based using an academic assessment tool (Objective Structured Clinical Examination [OSCE]). In a prospective controlled trial, 146 participants were randomly allocated to two groups (see one, do one and mastery learning) and trained in a 90-min module. In the see one, do one group, the trainer demonstrated the complete FAST routine, and then the students trained each other on it under supervision and received direct oral feedback from the tutors. In the mastery learning group, each student received a routing slip. The routing slip contained five levels of competence for the FAST routine, each of which had to be achieved (e.g., choosing the correct probe) and verified by the trainer before working toward the next competency level. The acquired competencies were assessed after training using the OSCE, which is a standardized practical exam using checklists. The mastery learning group attained 40.69 ± 5.6 points on average (of a maximum of 46 points), and the see one, do one group, 33.85 ± 7.7 points (p < 0.001). Mastery learning is an effective teaching method for undergraduate medical students performing FAST and is superior to the see one, do one approach, as assessed with the OSCE.

Abstract
BACKGROUND As the focused assessment with sonography for trauma (FAST) examination becomes increasingly ubiquitous in the emergency department (ED), a parallel increase in incidental findings can also be expected. The purpose of this study was to determine the prevalence, documentation, and communication of incidental findings on emergency physician-performed FAST examinations. METHODS Retrospective review at two academic EDs. Adult trauma patients undergoing FAST examinations used for clinical decision-making at the bedside were identified from an ED ultrasound image archival system. Expert sonologists reviewed ultrasound images for incidental findings, as well as electronic medical records for demographic information, mechanism of injury, type of incidental findings, documentation of incidental findings, and communication of incidental findings to the patient. RESULTS A total of 1,452 FAST examinations were reviewed. One hundred and thirty-seven patients with incidental findings were identified (9.4%); 7 patients had an additional incidental finding. Renal cysts were most common (49/144, 34.0%), followed by pelvic cysts in women (32/144, 22.2%). While 31/144 (21.5%) incidental findings were identified and documented in the ultrasound reports or medical records by ED providers, only 6/137 (4.4%) patients were noted to be informed of their incidental findings. CONCLUSION Incidental findings were often encountered in FAST examinations, with cysts of the kidneys and pelvis being the most common findings. A vast majority of incidental findings were not documented or noted to be communicated to patients, which can be a barrier to follow-up care.

Abstract
BACKGROUND Focused assessment with sonography for trauma (FAST) performance metrics are unknown in patients with non-compressible torso hemorrhage (NCTH). METHODS Retrospective review of a dedicated NCTH database from four level 1 trauma centers (2008-2012). NCTH was defined as (1) named axial torso vessel disruption; (2) AIS chest or abdomen >2 with shock (base deficit < -4) or truncal operation in ≤ 90 min; or (3) pelvic fracture with ring disruption. Patients were grouped by cavity of hemorrhage source and by shock (SBP ≤ 90). RESULTS 274 patients had a FAST prior to diagnosis of NCTH. FAST was positive in 51% of patients with abdominal/pelvic hemorrhage for a false negative rate (FNR) of 49%. FNR was higher for pelvic (61%) versus abdominal (43%) sources (p = 0.02). There was no difference between FAST negative or positive patients for ISS, shock, length of stay, or mortality (all p = NS). FNR was not improved among the subgroup of NCTH patients with shock (p = NS). CONCLUSION FAST identified abdominal/pelvic hemorrhage in approximately half of NCTH patients, and this was not improved among patients presenting with shock.

Abstract
BACKGROUND Before total body computed tomography scan, an initial rapid imaging assessment should be conducted in the trauma bay. It generally includes a chest x-ray, pelvic x-ray, and an extended focused ultrasonography assessment for trauma. This initial imaging assessment has been poorly described since the increase in the use of ultrasound. Therefore, our study aimed to evaluate the diagnostic accuracy and therapeutic impact of this initial imaging work-up in severe trauma patients. A secondary aim was to assess the therapeutic impact of a chest x-ray according to the lung ultrasonography findings. METHODS Patients with severe trauma who were admitted directly to our level 1 trauma center were consecutively included in this retrospective single center study. The diagnostic accuracy, therapeutic impact, and appropriate decision rate were calculated according to the initial assessment results of the whole body computed tomography scan and surgery reports. RESULTS Among the 1315 trauma patients admitted, 756 were included in this research. Lung ultrasound showed a higher diagnostic accuracy for haemothorax and pneumothorax cases than the chest x-ray. Sensitivity and specificity of the abdominal ultrasound to detect intraperitoneal effusion were 70% and 96%, respectively. The initial assessment had a therapeutic impact in 76 (10%) of the patients, including 16 (2%) immediate laparotomies and 58 (7%) chest tube insertions. The pelvic x-ray had no therapeutic impact, and when the lung ultrasound was normal, the chest x-ray had a therapeutic impact of only 0.13%. Combining the chest x-ray and lung ultrasound allowed adequate management of all the pneumothorax and haemothorax cases. Only one of the 756 patients had initial management that was judged as inappropriate. This patient had a missed pelvic disjunction with active retroperitoneal bleeding, and underwent an inappropriate immediate laparotomy. CONCLUSIONS In our cohort, the initial imaging assessment allowed appropriate decisions in 755 of 756 patients, with a global therapeutic impact of 10%. The pelvic x-ray had a minimal therapeutic impact, and in the patients with normal lung ultrasounds, the chest x-ray marginally affected the management of our patients. The potential consequences of abandoning systematic chest and pelvic x-rays should be investigated in future randomized prospective studies.

Abstract
OBJECTIVE Hemorrhagic shock is a relatively common occurrence in the postpartum period. In our hospital, we performed abdominal ultrasonography using the focused assessment with sonography for obstetrics (FASO) technique (a modified version of FAST). The aim of the present study was to determine the reference values for the ultrasonographic findings to establish the criteria for the diagnosis of a postpartum hemorrhage and severe shock using the FASO. METHODS The present prospective cohort study included all postpartum women who vaginally delivered singleton infants. Abdominal ultrasonography was performed after delivery. The observation points of ultrasonography were as follows: (1) the diameter of the intrauterine cavity, (2) the pouch of Douglas, (3) Morison's pouch, (4) between the spleen and kidney, and (5) the diameter of the inferior vena cava. RESULTS One hundred and eighty-two postpartum women were included in this study. The mean uterine cavity was 9.8 ± 7.3 mm. An echo-free space in the pouch of Douglas was observed in three cases, in one case in Morison's pouch, and not observed between the spleen and kidney. A negative correlation was found between the volume of bleeding and IVCi (p = 0.0008, r(2)= -0.061) and IVCe (p < 0.0001, r(2)= -0.106). CONCLUSIONS The present study establishes criteria that can be used to diagnose a postpartum hemorrhage or severe shock using the FASO.

Abstract
A biloma is a rare disease characterized by an abnormal intra- or extrahepatic bile collection due to a traumatic or spontaneous rupture of the biliary system. Laboratory findings are nonspecific. The diagnosis is usually suspected on the basis of a typical history (right upper quadrant abdominal pain, chills, fever and recent abdominal trauma or surgery) and is confirmed by detection of typical radiologic features. We report the case of a patient with a history of previous cholecystectomy for lithiasis who presented with clinical symptoms and laboratory data suggestive of acute pancreatitis. Imaging studies also revealed the presence of a chronic and asymptomatic biloma, which could be mistaken for a pseudocyst. The atypical location and ultrasound findings suggested an alternative diagnosis. We therefore reviewed the known literature for bilomas, focusing on the role of ultrasonography, which can reveal some typical aspects, such as location and imaging features. We conclude that ultrasound plays a key role in the assessment of a suspected biloma in patients with appropriate history and clinical features and provides valuable diagnostic clues even in the absence of these.

Abstract
OBJECTIVE Blunt abdominal trauma is a diagnostic challenge for emergency physicians and ultrasonography is one of the diagnostic tools used in this type of injuries. The aim of this study was to evaluate the diagnostic value of ultrasonographies performed by emergency physicians and radiologists. METHODS This prospective diagnostic study was performed in the emergency departments of two trauma centers in Iran during a period of 12 months. The subjects were all patients with blunt abdominal trauma that were candidated for abdominopelvic computed tomography (CT) scanning in our emergency departments. The results of focused assessment with sonography for trauma (FAST) performed by emergency physicians and radiologists were compared blindly with the results of CT scans performed by radiologists. The sensitivity, specificity, and predictive values of diagnosis for different abdominal anatomic areas were calculated. RESULTS In total, 450 patients undergoing FAST and CT scanning were studied. The sensitivity of radiologists' diagnoses for Morison's, splenorenal, perivesical, and pleural effusion areas were, respectively, 88.0, 70.0, 38.0, and 30.0 %. The corresponding values for emergency physicians' diagnoses were, respectively, 82.0, 60.0, 28.0, and 30.0 %. The specificity of radiologists' diagnoses in the mentioned areas were, respectively, 98.9, 100, 93.1, and 100 %, and for emergency physicians, they were, respectively, 98.9, 100, 96.0, and 100 %. CONCLUSION Emergency physicians showed a promising performance in applying FAST in blunt abdominal trauma. The specificity of ultrasonographic diagnosis in the emergency physicians group and the radiologists group were comparable, while radiologists showed a higher performance regarding the sensitivity of the ultrasonographic diagnosis.
