Predictive parameters for early detection of clinically relevant abdominal trauma in multiple-injury or polytraumatised patients: a retrospective analysis. Eur J Med Res 2024; 29:394. [PMID: 39080791 PMCID: PMC11288090 DOI: 10.1186/s40001-024-01969-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Accepted: 07/10/2024] [Indexed: 08/03/2024] Open
Abstract
Diagnosis of relevant organ injury after blunt abdominal injury (AI) in multiple-injury/polytraumatised patients is challenging. AI can be distinguished between injuries of parenchymatous organs (POI) of the upper abdomen (liver, spleen) and bowel and mesenteric injuries (BMI). Still, such injuries may be associated with delays in diagnosis and treatment. The present study aimed to verify laboratory parameters, imaging diagnostics, physical examination and related injuries to predict intraabdominal injuries. This retrospective, single-centre study includes data from multiple-injury/polytraumatised patients between 2005 and 2017. Two main groups were defined with relevant abdominal injury (AI+) and without abdominal injury (AI-). The AI+ group was divided into three subgroups: BMI+, BMI+/POI+, and POI+. Groups were compared in a univariate analysis for significant differences. Logistic regression analysis was used to determine predictors for AI+, BMI+ and POI+. 26.3% (271 of 1032) of the included patients had an abdominal injury. Subgroups were composed of 4.7% (49 of 1032) BMI+, 4.7% (48 of 1032) BMI+/POI+ and 16.8% (174 of 1032) POI+. Pathological abdominal signs had a sensitivity of 48.7% and a specificity of 92.4% for AI+. Transaminases were significantly higher in cases of AI+. Pathological computed tomography (CT) (free fluid, parenchymal damage, Bowel Injury Prediction Score (BIPS), CT Grade > 4) was summarised and had a sensitivity of 94.8%, a specificity of 98%, positive predictive value (PPV) of 94.5% and, negative predictive value (NPV) of 98.2% for AI+. The detected predictors for AI+ were pathological abdominal findings (odds ratio (OR) 3.93), pathological multi-slice computed tomography (MSCT) (OR 668.9), alanine (ALAT) ≥ 1.23 µmol/ls (OR 2.35) and associated long bone fractures (OR 3.82). Pathological abdominal signs, pathological MSCT and lactate (LAC) levels ≥ 1.94 mmol/l could be calculated as significant risk factors for BMI+. For POI+ pathological abdominal MSCT, ASAT ≥ 1.73 µmol/ls and concomitant thoracic injuries had significant relevance. The study presents reliable risk factors for abdominal injury and its sub-entities. The predictors can be explained by the anatomy of the trunk and existing studies. Elevated transaminases predicted abdominal injury (AI+) and, specifically, the POI+. The pathological MSCT was the most reliable predictive parameter. However, it was essential to include further relevant parameters.

Abstract
The use of ultrasound while caring for critically ill patients has been increasing exponentially in the last two decades and now is an essential component of intensive care practice. Abdominal ultrasound is an established technique in other specialties, but its use in intensive care has lagged behind other ultrasound modalities. However, its potential role in the diagnosis and management of patients will make it an invaluable tool for intensivists. The main use of abdominal ultrasound at the bedside is for free fluid detection in trauma patients. But abdominal ultrasound can also help us diagnose patients with abdominal pain, hypovolemia or anuria, and it can guide us during procedures such as paracentesis or bladder catheter and gastric tube placement.

Abstract
Trauma is the number one cause of death among Americans between the ages of 1 and 46 years, costing more than $670 billion a year. Following death related to central nervous system injury, hemorrhage accounts for the majority of remaining traumatic fatalities. Among those with severe trauma that reach the hospital alive, many may survive if the hemorrhage and traumatic injuries are diagnosed and adequately treated in a timely fashion. This article aims to review the recent advances in pathophysiology management following a traumatic hemorrhage as well as the role of diagnostic imaging in identifying the source of hemorrhage. The principles of damage control resuscitation and damage control surgery are also discussed. The chain of survival for severe hemorrhage begins with primary prevention; however, once trauma has occurred, prehospital interventions and hospital care with early injury recognition, resuscitation, definitive hemostasis, and achieving endpoints of resuscitation become paramount. An algorithm is proposed for achieving these goals in a timely fashion as the median time from onset of hemorrhagic shock and death is 2 h.

Abstract
The peritoneum is a large serosal membrane enveloping the abdomen and pelvic organs and forming the peritoneal cavity. This complex relationship forms many named abdominopelvic spaces, which are frequently involved in infectious, inflammatory, neoplastic, and traumatic pathologies. The knowledge of this anatomy is essential to the radiologist to localize and describe the extent of the disease accurately. This manuscript provides a comprehensive pictorial review of the peritoneal anatomy to describe pathologic fluid and gas.

Abstract
Introduction: Concomitant gallstones and common bile duct (CBD) stones is a common problem, and there is still no consensus on the best approach in the management. Options include preoperative endoscopic retrograde cholangiopancreatography (ERCP), Laparoscopic cholecystectomy (LC) with CBD exploration, and LC with postoperative ERCP. Each option has its own limitations and complications. In this article, we assessed the feasibility of laparoscopic surgical clearance of the CBD after a failed ERCP, reasons for failure of endoscopic clearance in our cohort. We will discuss the management options after ERCP failure, the challenges, and the outcomes. Materials and Methods: We retrospectively reviewed all the cases of laparoscopic common bile duct exploration (LCBDE) performed in our hospital between April 2006 and January 2019. Two hundred cases were performed, 178 cases as a primary procedure while 22 were performed as a secondary procedure after failed ERCP. We have previously published data on the case series (PMID 33140155) and here explored the cases performed after failed ERCP as a secondary procedure. We analyzed demographics of patients, preoperative investigations, ERCP trials, and reasons for ERCP failure, operative approach, duration of operation, conversion rate, complications, and outcomes. Results: Twenty-two patients underwent a laparoscopic CBD clearance after failed ERCP. Sixteen of these were in the first 5 years of the study. Multiple attempts of ERCP were made in 7 patients (31.8%) and a single attempt in 15 patients. In 8 patients (32%), the duct was not accessible (failed cannulation) due to a variety of reasons. Nine patients had impacted stones larger than 1 cm, 4 patients had Mirrizi syndrome with concomitant large CBD stones, and 1 patient failed endoscopic clearance because of the large number of stones in the CBD. CBD clearance was successful in 19 patients (88%), 8 were completed by a transcystic approach and 14 by a transcholedochal approach. Postoperative length of stay was 12 (+10) days. One patient had an unplanned readmission within 30 days. One patient required reoperation for bleeding. Three patients developed recurrent stones and 1 developed a subsequent stricture. No mortalities were recorded. Conclusion: LCBDE is feasible and appears safe as a secondary procedure after failed ERCP. The new technologies and the advancement of surgical techniques will continue to improve success and reduce morbidity.

Abstract
The widespread use of portable ultrasound scanners has promoted the concept of point of care ultrasound (POCUS), namely "ultrasound performed bedside and interpreted directly by the clinician." The purpose of this short review is to outline how POCUS can be used in patients with diseases of the gastrointestinal (GI) tract. POCUS is not a replacement for comprehensive ultrasound, but rather allows physicians immediate access to clinical imaging for rapid diagnosis and efficient work-up and treatment of the patients. There are many indications for doing POCUS of the GI tract, including abdominal pain, diarrhea, palpable masses, and to detect fluid or free air in the abdominal cavity. To improve the visibility of deeper parts of the abdomen, the graded compression technique with the scan head is useful. During POCUS, the operator should look for signs of severe pathology including target lesions, the pseudo-kidney sign, the onion sign, dilated bowel loops, gastric retention, free fluid, and free air, depending on the actual clinical problem. We conclude that POCUS of the GI tract is very useful to provide a rapid diagnosis in many clinical scenarios.

Abstract
Background The use of ultrasonography in the intensive care unit (ICU) is steadily increasing but is usually restricted to examinations of single organs or organ systems. In this study, we combine the ultrasound approaches the most relevant to ICU to design a whole-body ultrasound (WBU) protocol. Recommendations and training schemes for WBU are sparse and lack conclusive evidence. Our aim was therefore to define the range and prevalence of abnormalities detectable by WBU to develop a simple and fast bedside examination protocol, and to evaluate the value of routine surveillance WBU in ICU patients. Methods A protocol for focused assessments of sonographic abnormalities of the ocular, vascular, pulmonary, cardiac and abdominal systems was developed to evaluate 99 predefined sonographic entities on the day of admission and on days 3, 6, 10 and 15 of the ICU admission. The study was a clinical prospective single-center trial in 111 consecutive patients admitted to the surgical ICUs of a tertiary university hospital. Results A total of 3003 abnormalities demonstrable by sonography were detected in 1275 individual scans of organ systems and 4395 individual single-organ examinations. The rate of previously undetected abnormalities ranged from 6.4 ± 4.2 on the day of admission to 2.9 ± 1.8 on day 15. Based on the sonographic findings, intensive care therapy was altered following 45.1% of examinations. Mean examination time was 18.7 ± 3.2 min, or 1.6 invested minutes per detected abnormality. Conclusions Performing the WBU protocol led to therapy changes in 45.1% of the time. Detected sonographic abnormalities showed a high rate of change in the course of the serial assessments, underlining the value of routine ultrasound examinations in the ICU. Trial registration The study was registered in the German Clinical Trials Register (DRKS, 7 April 2017; retrospectively registered) under the identifier DRKS00010428. Supplementary Information The online version contains supplementary material available at 10.1186/s13054-021-03811-2.

Abstract
It is generally recognized that lives are saved by administering high-quality cardiopulmonary resuscitation (CPR) to patients in cardiac arrest. A focused assessment with sonography for trauma (FAST) examination is an effective and non-invasive method for detecting rare complications of CPR, such as hemorrhage from abdominal visceral injury. We report the case of a 56-year-old female suffering from intra-abdominal hemorrhage caused by a liver laceration following CPR. The hemoperitoneum was diagnosed by a FAST examination. Although severe complications of CPR are rare, they can be easily detected with the use of a FAST examination. A FAST examination should be considered as a post-resuscitation approach to assess for life-threatening complications in all patients following cardiopulmonary resuscitation.

Abstract
PURPOSE In children with blunt abdominal trauma (BAT), focused assessment of sonography in trauma (FAST) has been reported with low sensitivity, on the whole, in the detection of intra-abdominal injuries (IAI). The aim of the present study was to assess test characteristics of FAST using different strategies including repeated FAST (reFAST), and physical exam findings. METHODS This retrospective study evaluated BAT pediatric patients with stable hemodynamics who underwent computed tomography (CT). Demographic data, initial physical examination, and results of FAST, reFAST (if done), and CT imaging were recorded. Different strategies of FAST were cross-tabulated with CT as the gold standard and test characteristics including sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were interpreted. RESULTS 129 patients with a mean age of 8.6 ± 4.7 were studied and 74% were male. Comparing CT-positive and -negative groups, from the demographic and clinical findings, only positive physical exam (tenderness or ecchymosis) was significantly higher in the CT-positive group (59% vs. 17%; p < 0.01). In a multivariate analysis, positive FAST modality and clinical exam remained independent predictors for a positive CT result (likelihood ratios of 34.6 and 6.4, respectively). Out of the different diagnostic strategies for the prediction of IAI, the best overall performance resulted from the FAST-reFAST-tenderness protocol with sensitivity, specificity, PPV, NPV, and accuracy of 87%, 77%, 70%, 91%, and 81%. CONCLUSION For children with blunt abdominal trauma, physical examination plus FAST and reFAST as needed, seems to have reasonable sensitivity, specificity, and accuracy in detecting intra-abdominal injuries and may reduce the need for CT scans.

Abstract
BACKGROUND Focused Abdominal Sonography for Trauma (FAST) examination has long been proven useful in the management of adult trauma patients, however, its utility in pediatric trauma patients is not as proven. Our goal was to evaluate the utility of a FAST examination in predicting the success or failure of nonoperative management (NOM) of blunt liver and/or spleen (BLSI) in the pediatric trauma population. METHODS A retrospective analysis of a prospective observational study of patients younger than 18 years presenting with BLSI to one of ten Level I pediatric trauma centers between April 2013 and January 2016. 1,008 patients were enrolled and 292 had a FAST examination recorded. We analyzed failure of NOM of BLSI in the pediatric trauma population. We then compared FAST examination alone or in combination with the pediatric age adjusted shock index (SIPA) as it relates to success of NOM of BLSI. RESULTS Focused Abdominal Sonography for Trauma examination had a negative predictive value (NPV) of 97% and positive predictive value (PPV) of 13%. The odds ratio of failing with a positive FAST examination was 4.9 and with a negative FAST was 0.20. When combined with SIPA, a positive FAST examination and SIPA had a PPV of 17%, and an odds ratio for failure of 4.9. The combination of negative FAST and SIPA had an NPV of 96%, and the odds ratio for failure was 0.20. CONCLUSION Negative FAST is predictive of successful NOM of BLSI. The addition of a positive or negative SIPA score did not affect the PPV or NPV significantly. Focused Abdominal Sonography for Trauma examination may be useful clinically in determining which patients are not at risk for failure of NOM of BLSI and do not require monitoring in an intensive care setting. LEVEL OF EVIDENCE Prognostic study, level IV; therapeutic/care management, level IV.

Abstract
Background Point-of-care ultrasound (POCUS) has many applications in emergency medicine, which have been proven to improve patient outcomes. Training programs and well-established guidelines for its use are available, but Canadian adoption rates and attitudes toward this technology have not been recently assessed. Objectives This study aimed to provide a national assessment of the current use of POCUS in Canadian emergency departments (ED) including patterns of use, attitudes towards its role, descriptors of training experience, as well as barriers to increased utilization. Methods An electronic survey was sent to physician members of the Canadian Association of Emergency Physicians. The survey included questions related to demographics, attitudes towards POCUS, POCUS utilization, and barriers to POCUS use. Responses were statistically analyzed to identify significant associations. Results Responses demonstrated a strong association between POCUS training and amount of POCUS usage. Neither hospital type nor community type was associated with the degree of POCUS usage. POCUS was most widely adopted for Canadian Point of Care Ultrasound Society (CPOCUS) core applications and has increased since the last national survey. The most commonly reported barrier to increased POCUS adoption was the lack of training. Most physicians have formal POCUS training in core applications, and approximately one third have advanced training. Conclusions POCUS training and utilization appear to have increased since the last national assessment. This provides a foundation for future POCUS research.

The focused assessment with sonography in trauma (FAST) in hypotensive injured patients frequently fails to identify the need for laparotomy: a multi-institutional pragmatic study. Trauma Surg Acute Care Open 2019; 4:e000207.

Abstract
Background The ability of focused assessment with sonography for trauma (FAST) to detect clinically significant hemorrhage in hypotensive injured patients remains unclear. We sought to describe the sensitivity and specificity of FAST using findings at laparotomy as the confirmatory test. Methods Patients from the Prospective Observational Multicenter Major Trauma Transfusion (PROMMTT) study that had a systolic blood pressure < 90mm Hg and underwent FAST were analysed. Results were compared with findings at laparotomy. A therapeutic laparotomy (T-LAP) was defined as an abdominal operation within 6 hours in which a definitive procedure was performed. The sensitivity and specificity of FAST were calculated. Results The cohort included 317 patients that underwent FAST (108 positive, 209 negative). T-LAP was performed in 69% (n=75) of FAST(+) patients and 22% (n=48) of FAST(−) patients. FAST had a sensitivity of 62% and specificity of 83%. Conclusions In our multicenter cohort, 22% of FAST(−) patients underwent T-LAP within 6 hours of admission. In hypotensive patients with a negative FAST, clinicians should still maintain a high index of suspicion for significant abdominal hemorrhage. Level of evidence Level IV.

Abstract
BACKGROUND Point-of-care sonography (POCS) has emerged as the screening modality of choice for suspected body trauma in many emergency departments worldwide. Its best known application is FAST (focused abdominal sonography for trauma). The technology is almost ubiquitously available, can be performed during resuscitation, and does not expose patients or staff to radiation. While many authors have stressed the high specificity of POCS, its sensitivity varied markedly across studies. This review aimed to compile the current best evidence about the diagnostic accuracy of POCS imaging protocols in the setting of blunt thoracoabdominal trauma. OBJECTIVES To determine the diagnostic accuracy of POCS for detecting and excluding free fluid, organ injuries, vascular lesions, and other injuries (e.g. pneumothorax) compared to a diagnostic reference standard (i.e. computed tomography (CT), magnetic resonance imaging (MRI), thoracoscopy or thoracotomy, laparoscopy or laparotomy, autopsy, or any combination of these) in patients with blunt trauma. SEARCH METHODS We searched Ovid MEDLINE (1946 to July 2017) and Ovid Embase (1974 to July 2017), as well as PubMed (1947 to July 2017), employing a prospectively defined literature and data retrieval strategy. We also screened the Cochrane Library, Google Scholar, and BIOSIS for potentially relevant citations, and scanned the reference lists of full-text papers for articles missed by the electronic search. We performed a top-up search on 6 December 2018, and identified eight new studies which may be incorporated into the first update of this review. SELECTION CRITERIA We assessed studies for eligibility using predefined inclusion and exclusion criteria. We included either prospective or retrospective diagnostic cohort studies that enrolled patients of any age and gender who sustained any type of blunt injury in a civilian scenario. Eligible studies had to provide sufficient information to construct a 2 x 2 table of diagnostic accuracy to allow for calculating sensitivity, specificity, and other indices of diagnostic test accuracy. DATA COLLECTION AND ANALYSIS Two review authors independently screened titles, abstracts, and full texts of reports using a prespecified data extraction form. Methodological quality of individual studies was rated by the QUADAS-2 instrument (the revised and updated version of the original Quality Assessment of Diagnostic Accuracy Studies list of items). We calculated sensitivity and specificity with 95% confidence intervals (CI), tabulated the pairs of sensitivity and specificity with CI, and depicted these estimates by coupled forest plots using Review Manager 5 (RevMan 5). For pooling summary estimates of sensitivity and specificity, and investigating heterogeneity across studies, we fitted a bivariate model using Stata 14.0. MAIN RESULTS We included 34 studies with 8635 participants in this review. Summary estimates of sensitivity and specificity were 0.74 (95% CI 0.65 to 0.81) and 0.96 (95% CI 0.94 to 0.98). Pooled positive and negative likelihood ratios were estimated at 18.5 (95% CI 10.8 to 40.5) and 0.27 (95% CI 0.19 to 0.37), respectively. There was substantial heterogeneity across studies, and the reported accuracy of POCS strongly depended on the population and affected body area. In children, pooled sensitivity of POCS was 0.63 (95% CI 0.46 to 0.77), as compared to 0.78 (95% CI 0.69 to 0.84) in an adult or mixed population. Associated specificity in children was 0.91 (95% CI 0.81 to 0.96) and in an adult or mixed population 0.97 (95% CI 0.96 to 0.99). For abdominal trauma, POCS had a sensitivity of 0.68 (95% CI 0.59 to 0.75) and a specificity of 0.95 (95% CI 0.92 to 0.97). For chest injuries, sensitivity and specificity were calculated at 0.96 (95% CI 0.88 to 0.99) and 0.99 (95% CI 0.97 to 1.00). If we consider the results of all 34 included studies in a virtual population of 1000 patients, based on the observed median prevalence (pretest probability) of thoracoabdominal trauma of 28%, POCS would miss 73 patients with injuries and falsely suggest the presence of injuries in another 29 patients. Furthermore, in a virtual population of 1000 children, based on the observed median prevalence (pretest probability) of thoracoabdominal trauma of 31%, POCS would miss 118 children with injuries and falsely suggest the presence of injuries in another 62 children. AUTHORS' CONCLUSIONS In patients with suspected blunt thoracoabdominal trauma, positive POCS findings are helpful for guiding treatment decisions. However, with regard to abdominal trauma, a negative POCS exam does not rule out injuries and must be verified by a reference test such as CT. This is of particular importance in paediatric trauma, where the sensitivity of POCS is poor. Based on a small number of studies in a mixed population, POCS may have a higher sensitivity in chest injuries. This warrants larger, confirmatory trials to affirm the accuracy of POCS for diagnosing thoracic trauma.

Abstract
BACKGROUND AND AIMS Laparoscopy in blunt abdominal trauma is challenging because of multiple associated injuries, higher trauma score values and higher morbidity and mortality, as compared with patients with penetrating abdominal trauma. The aim of this study was to investigate the role of laparoscopy in the management of blunt abdominal trauma patients and to highlight related challenges. MATERIAL AND METHODS Over a 4-year period, patients managed laparoscopically for blunt abdominal trauma were retrospectively analyzed. Perioperative details, indications for laparoscopy and conversion, complications, and length of hospital stay were discussed. RESULTS A total of 35 stable patients underwent laparoscopy. The mean Injury Severity Score was 12 (4-38). Therapeutic laparoscopy was performed in 15 (56%) and diagnostic in 12 (44%) patients. Eight (23%) patients were converted to therapeutic laparotomy. Intraoperative bleeding, complex injuries, visualization problem, and equipment failure necessitated conversion. Three (30%) patients with negative computed tomography scan had therapeutic laparoscopy for mesenteric injuries. There were no missed injuries. The mean length of hospital stay was 11 days in both groups. CONCLUSION Laparoscopy for stable patients is feasible and safe. Multiple injuries make laparoscopy more difficult, and advanced laparoscopic skills are required. The conversion rate is high; however, the non-therapeutic laparotomies were completely eliminated in this study.

Abstract
The original and most widely accepted applications for point-of-care ultrasound (POCUS) are in the settings of trauma, shock, and bedside procedures. Trauma was the original setting for the introduction of POCUS and has been standardized under the four-plus view examination called the Focused Assessment with Sonography in Trauma (FAST). This examination was found to be especially practice changing for achieving rapid diagnoses in critically ill patients who are too unstable for the delays and transportation inherent in more advanced imaging with computed tomography. This application was broadened from the critically ill trauma patient to any critically ill patient, particularly the patient in undifferentiated shock. Although the Focused Assessment with Sonography in Trauma examination originally focused on sources of hemorrhage causing hypovolemic shock, POCUS also can quickly differentiate cardiogenic, obstructive, and distributive shock and help identify the more specific etiology such as massive pulmonary emboli, pericardial tamponade, and pneumothoraces. By expediting diagnosis, POCUS facilitates faster definitive treatment of life-threatening conditions. In pursuing treatment, US continues to serve a role in the form of visually guiding many procedures that were previously done blindly. US guidance of procedures has improved the safety of central line insertion, thoracentesis, and paracentesis, and has an emerging role in lumbar puncture. Experience in bedside US is becoming a vital tool in the clinician's bedside assessment and management, filling a void between the stethoscope and the more advanced studies and interventions available through radiology. Understanding the strengths and limitations of US enables clinicians to identify the appropriate situations in which they can apply this tool confidently.

Abstract
BACKGROUND Hemothorax is most commonly resulted from a closed chest trauma, while a tube thoracostomy (TT) is usually the first procedure attempted to treat it. However, TT may lead to unexpected results and complications in some cases. The advantage of thoracic ultrasound (TUS) over a physical examination combined with chest radiograph (CXR) for diagnosing hemothorax1 has been proposed previously. However, its benefits in terms of avoiding non-therapeutic TT have not yet been confirmed. Therefore, this study is aimed to evaluate the severity of hemothorax in blunt chest trauma patients by using TUS in order to avoid non-therapeutic TT in stable cases. METHODS The data from 46,036 consecutive patient visits to our trauma center over a four-year period were collected, and those with blunt chest trauma were identified. Patients who met any of the following criteria were excluded: transferred from another facility, with an abbreviated injury scale (AIS) score ≥ 2 for any region except the chest region, with a documented finding of tension pneumothorax or pneumothorax >10%, younger than 16 years old and with indications requiring any non-thoracic major operation. The decision to perform TT for those patients in the non-TUS group was made on the basis of CXR findings and clinical symptoms. The continuous data were analyzed by using the two-tailed Student's t test, and the discrete data were analyzed by Chi-square test. RESULTS A total of 84 patients met the criteria for inclusion in the final analysis, with TT having been performed on 42 (50%) of those patients. The mean volume of the drainage amount was 860 ml after TT. The TT drainage was less than 500 ml in 12 patients in the non-TUS group (40%), while none was less than 500 ml in the TUS group (p = 0.036, Fisher's exact test). In terms of the positive rate of subsequent effective TT, the sensitivity of TUS was 90% and the specificity was 100%. There were 3 patients with delayed hemothorax: 2 of the 58 (3.6%) in the non-TUS group and 1 of 26 (4.5%) in the TUS group (p > 0.05, Fisher's exact test). The hospital length of stay in the non-TUS group with non-therapeutic TT was significantly longer than in the TUS group without TT (8.2 vs. 5.4 days, p = 0.018). There were no other major complications or deaths in either group during the 90-day follow-up period. CONCLUSION In the case of blunt trauma, TUS can rapidly and accurately evaluate hemothorax to avoid TT in patients who may not benefit much from it. As a result, the rate of non-therapeutic TT can be decreased, and the influence on shortening hospital length of stay may be further evaluated with prospective controlled study.

Abstract
INTRODUCTION Focused assessment with sonography in trauma (FAST) is historically an effective method of assessing the patient in the trauma bay in order to aid decision-making and optimise patient outcomes. However, in the UK civilian practice, the use of FAST may decline given a recent change in National Institute for Health and Care Excellence guidance as a result of improvement in CT availability and resuscitation techniques. METHOD In the Role 3 Medical Treatment Facility, Camp Bastion, 187 patients with trauma who received FAST in the trauma bay in 2014 were reviewed to determine the accuracy of FAST in the deployed environment. RESULTS The data demonstrates the sensitivity and specificity of FAST to be 75% and 99.3%, respectively. CONCLUSIONS This study demonstrates that FAST is accurate on operations. FAST is provided by the integrated radiologist as part of damage control radiology, which gives the team leader rapid diagnostic information to improve decision-making and ultimately patient outcomes. CT is heavily utilised in civilian practice; however, the military operates in a different environment often with multiple casualties and limited access to CT, as a result, portable ultrasound will continue to be a valuable tool on operations if used properly. The next challenge is to develop and maintain this high diagnostic accuracy in future deployments where the memories of our prior success may fade.

Abstract
INTRODUCTION It could be claimed that extended focused assessment with sonography for trauma (e-FAST) is the most important use of ultrasound in every emergency department (ED). It is a rapid, repeatable, non-invasive bedside method that was designed to answer one single question, which is, "whether free fluid is present in the peritoneal, pleural and pericardial cavity or not?" This examination may also be used to evaluate the lungs for pneumothorax. OBJECTIVE The current comparative study was conducted to assess the accuracy and reproducibility of e-FAST performed by emergency medicine residents (EMRs) and radiology consultants (RCs) in multiple trauma patients. METHOD This diagnostic accuracy study was conducted prospectively in patients presenting over a period of 12 months from January 1, 2013, to December 31, 2013 to the ED of Kerala Institute of Medical Sciences (KIMS), Kerala, India. All multiple trauma patients older than 18 years of age presenting within 24 hours of their traumatic event, who underwent both e-FAST and thoracoabdominal computed tomography (CT) scan were included. The e-FAST exams were first performed by the EMRs and then by RCs. The thoracoabdominal CT scan findings were considered as the gold standard. The results were compared between both groups to assess the inter-observer variability. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated both for EMRs and RCs. RESULTS In the study period, 150 patients with a mean age of 42.06 ± 18.1 years were evaluated (76.7% male). Only 19 cases (12.7%) had a history of fall from a height, and the others were admitted due to RTA. Thirty-four cases (22.7%) did not require surgery; but the others underwent various interventions. Both EMRs and RCs reported positive findings in 20 cases (13.3%) and negative findings in 130 cases (86.7%). The correlation of e-FAST done by EMRs with that by RCs was 100%. E-FAST exam had a sensitivity of 90.4%, specificity 99.2%, PPV 95.0%, NPV 98.4%, and accuracy 98%, both for EMRs and RCs. CONCLUSION Based on the findings, the sensitivity, specificity, and accuracy of e-FAST exams performed by EMRs were equal to those performed by RCs. It seems that e-FAST performed by EMRs were almost accurate during the initial trauma resuscitation in the ED of a level one trauma center in India.

Abstract
The use of ultrasonography (US) as an imaging modality in medicine has spread across almost every clinical specialty. This diffusion is based on the simplicity, accessibility, portability and affordability of the technique producing real-time high-resolution images using non-ionising radiation. On the other hand, this trend also extended the technique to settings other than healthcare, such as public facilities, private houses or remote sites. This tendency can be observed worldwide, from developing countries to prestigious medical schools and tertiary referral hospitals. Furthermore, point-of-care US (POCUS), i.e., US executed at the patient's bedside to obtain real-time objective information with diagnostic and clinical monitoring purposes or to guide invasive procedures, has been incorporated in many specialties. In gastroenterology, despite the essential role of endoscopy, clinical practice is highly dependent on non-endoscopic imaging techniques. However, as in other specialties, the indications of US in gastroenterology have been increasing steadily, covering a broad range of conditions. In response to the generalised employment of US by non-radiologists, institutions such as the European Federation of Societies for Ultrasound in Medicine and Biology and the Royal College of Radiologists issued recommendations to ensure high-quality practice. These theoretical and practical requisites include performing a certain number of examinations and mandatory skills in order to achieve certification to execute unsupervised US. Therefore, there is a need for modern gastroenterology to include US as a basic skill in its clinical practice. To ensure the provision of high-quality US, adequate instruction of future specialists should be guaranteed by the gastroenterology departments and required in the residency training programme.

Abstract
Objective This study compares the positive predictive value (PPV) and negative predictive value (NPV) of focused assessment with sonography in trauma (FAST) versus abdominal-pelvic computed tomography scans (CTAP) after blunt abdominal injury as well as the need for abdominal surgery. We also sought to determine if any false negative ultrasound studies were associated with significant morbidity. The results were compared with other studies. Design Retrospective cross-sectional study. Setting A tertiary hospital. Methods Cases were retrieved from the trauma registry and electronic medical records in a tertiary hospital in Singapore over a two year period from 1 January 2009 to 31 December 2010. Exclusion criteria included penetrating trauma and burns. The sonographic finding, computed tomography finding, and the outcome of the patients were retrieved. Diagnostic characteristics including predictive values were calculated. Results A total of 476 patients were enrolled. Four hundred fifty-nine patients had FAST performed with fifty (10.9%) being positive. Forty-nine patients (21.7%) out of 226 patients had CTAP which showed abnormalities and nineteen (4.0%) patients underwent surgery. Comparing FAST to detect abnormalities on CTAP, the PPV and NPV were 0.590 and 0.863 respectively. Comparing FAST with the need for surgery, the PPV and NPV were 0.280 and 0.990 respectively. Four patients (0.98%) had negative FAST but required surgery. There were no significant adverse outcomes or surgical intervention in patients with normal vital signs, normal initial physical examination and negative FAST findings but who did not have a CTAP. Conclusions In patients with an initial normal physical examination and negative FAST, emergent CTAP may be avoided. (Hong Kong j.emerg.med. 2014;21:230-236)

Abstract
Equivocal focused abdominal sonography for trauma (FAST) examinations confound decision-making for trauma surgeons. We sought to determine whether the equivocal FAST (defined as any nonconcordant result) has a deleterious effect on trauma outcomes. A 2-year review (2014–2015) of all trauma activations at our Level I trauma center was performed. Patients were matched at baseline and FAST results were compared. Outcomes included resuscitation time (h), ventilation days (d), hospital length of stay (HLOS-d), ICU length-of-stay, and survival (%). In addition, skill level of the sonographer was stratified by novice (postgraduate year (PGY) years 1–3) or expert skill levels (PGY-4/fellow or attending). A total of 1,027 patients were included. Compared with concordant FAST examinations, equivocal FASTs were associated with increased HLOS (14.1 vs 10.6, P = 0.05), higher mortality (9.8 vs 3.7%, P = 0.02), decreased positive predictive value in the right upper quadrant (RUQ) (55 vs 79%, P = 0.02) and left upper quadrant (LUQ) (50 vs 83%, P < 0.01) and significantly decreased specificity in the thoracic (83 vs 98%), RUQ (80 vs 98%), LUQ (86 vs 99%), and pelvic (88 vs 98%) windows (P < 0.01 for all). A trend of greater positive predictive value in the thoracic window (100 vs 81%, P = 0.09) among PGY-4/fellow and attending providers compared with PGY levels 1–3 was observed. Equivocal FASTs portend worse outcomes than concordant FASTs because of high false-negative rates, specifically in the thoracic region and the upper quadrants. Lower thresholds for intervention are recommended.

Abstract
We present a 4-week-old neonate with acute onset of bloody stools and abdominal distention. Point-of-care ultrasound performed in the emergency department allowed for rapid diagnosis of a large amount of free intra-abdominal fluid, which together with the physical findings, prompted emergent operative exploration revealing chylous ascites. Although no areas of active volvulus were identified intraoperatively, findings in the case were suggestive of small bowel volvulus and deemed as the most likely etiology for this patient's presentation. In this report, we review the relevant aspects of ultrasonography for ascites and discuss the diagnosis of chylous ascites.

Abstract
PURPOSES Researchers studying trauma have found that physicians are able to perform a focused assessment with sonography for trauma (FAST) with minimal training and achieve ideal accuracy. However, there are currently no consensus or standard guidelines regarding the performance of this assessment. The aim of our study was to clarify the value of FAST performed by well-qualified senior general surgery residents in cases of suspected blunt abdominal trauma, which presents an important diagnostic problem in emergency departments. METHODS This was a retrospective study in the emergency department (ED) of our hospital performed from January 2011 to September 2013. Patients were included if they (1) had undergone a FAST examination performed by qualified residents and (2) had received subsequent formal radiographic or surgical evaluations. The results were compared against subsequent surgical findings or formal Department of Radiology reference standards. RESULTS Among the 438 patients enrolled, false-negative results were obtained in 8 and false-positive results in 5. Only one patient was missed and required laparotomy to repair a small intestine perforation. The sensitivity and specificity were 87 and 99%, respectively; the accuracy was 97%. CONCLUSIONS Senior general surgery residents can be trained to perform accurate FAST examinations on trauma patients.

Abstract
The management of blunt abdominal trauma has evolved over time. While laparotomy is the standard of care in hemodynamically unstable patients, stable patients are usually treated by non-operative management (NOM), incorporating adjuncts such as interventional radiology. However, although NOM has shown good results in solid organ injuries, other lesions, namely those involving the hollow viscus, diaphragm, and mesentery, do not qualify for this approach and need surgical exploration. Laparoscopy can substantially reduce additional surgical aggression. It has both diagnostic and therapeutic potential and, when negative, may reduce the number of unnecessary laparotomies. Although some studies have shown promising results on the use of laparoscopy in blunt abdominal trauma, randomized controlled studies are lacking. Laparoscopy requires adequate training and experience as well as sufficient staffing and equipment.

Abstract
BACKGROUND The number of citations a scientific article receives provides a good indication of its impact within any given field. This bibliometric analysis aimed to identify the 100 most cited articles in Emergency Abdominal Surgery (EAS), to highlight key areas of interest and identify those that have most significantly shaped contemporary clinical practice in this newly evolving surgical specialty. This is of increasing relevance as concerns grow regarding the variable and suboptimal outcomes in Emergency General Surgery. MATERIALS AND METHODS The Thomson Reuters Web of Science database was used to search using the terms [Emergency AND Abdom* AND Surg*] to identify all English language, full manuscripts. Results were ranked according to citation number. The top 100 articles were further analysed by subject, author, journal, year of publication, institution, and country of origin. RESULTS The median (range) citation number of the top 100 out of 7433 eligible papers was 131 (1569-97). The most cited paper (by Goldman et al., Massachusetts General Hospital, New England Journal of Medicine; 1569 citations) focused on cardiac risk stratification in non-cardiac surgery. The Journal of Trauma, Injury, Infection and Critical Care published the most papers and received most citations (n = 19; 2954 citations. The majority of papers were published by centres in the USA (n = 52; 9422 citations), followed by the UK (n = 13; 1816 citations). The most common topics of publication concerned abdominal aneurysm management (n = 26) and emergency gastrointestinal surgery (n = 26). CONCLUSION Vascular surgery, risk assessment and gastrointestinal surgery were the areas of focus for 59% of the contemporary most cited emergency abdominal surgery manuscripts. By providing the most influential references this work serves as a guide to what makes a citable emergency surgery paper.

Abstract
BACKGROUND AND STUDY AIMS Trauma is one of the most common causes of morbidity and mortality in the pediatric population. The diagnosis of pancreatic injury is based on clinical presentation, laboratory and imaging findings, and endoscopic methods. CT scanning is considered the gold standard for diagnosing pancreatic trauma in children. PATIENTS AND METHODS This retrospective study evaluates data from 25 pediatric patients admitted to the University Hospital Motol, Prague, with blunt pancreatic trauma between January 1999 and June 2013. RESULTS The exact grade of injury was determined by CT scans in 11 patients (47.8%). All 25 children underwent endoscopic retrograde cholangiopancreatography (ERCP). Distal pancreatic duct injury (grade III) was found in 13 patients (52%). Proximal pancreatic duct injury (grade IV) was found in four patients (16 %). Major contusion without duct injury (grade IIB) was found in six patients (24%). One patient experienced duodeno-gastric abruption not diagnosed on the CT scan. The diagnosis was made endoscopically during ERCP. Grade IIB pancreatic injury was found in this patient. One patient (4%) with pancreatic pseudocyst had a major contusion of pancreas without duct injury (grade IIA). Four patients (16%) with grade IIB, III and IV pancreatic injury were treated exclusively and nonoperatively with a pancreatic stent insertion and somatostatine. Two patients (8%) with a grade IIB injury were treated conservatively only with somatostatine without drainage. Eighteen (72 %) children underwent surgical intervention within 24 h after ERCP. CONCLUSION ERCP is helpful when there is suspicion of pancreatic duct injury in order to exclude ductal leakage and the possibility of therapeutic intervention. ERCP can speed up diagnosis of higher grade of pancreatic injuries.

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
PURPOSE To evaluate the feasibility of a new protocol, Chest Abdominal-Focused Assessment Sonography for Trauma (CA-FAST), during the primary survey and to estimate its diagnostic accuracy when compared with thoracoabdominal computed tomography (CT) scan. METHODS A prospective accuracy study was performed from November 2012 to November 2013 at the Emergency Department. Only adult trauma patients who underwent a CA-FAST examination prior to a thoracoabdominal CT scan were enrolled. In addition to standard patterns detected by Extended-FAST (E-FAST) such as pneumothorax (PTX), hemothorax (HTX), pericardial and intraabdominal effusion, CA-FAST protocol also included the research of lung contusions (LCs). RESULTS Six hundred and one patients were enrolled. The mean time for protocol execution was 7 ± 3 min. Chest ultrasonography showed the following results (all p < 0.001): LCs sensitivity 59 %, specificity 98 %, positive predictive value (PPV) 92 %, negative predictive value (NPV) 86 %, accuracy 87 %; PTX sensitivity 84 %, specificity 98 %, PPV 93 %, NPV 95 %, accuracy 95 %; HTX sensitivity 82 %, specificity 97 %, PPV 87 %, NPV 95 %, accuracy 94 %. The standard 4-views FAST examination showed a diagnostic accuracy of 91 % with a sensitivity of 75 %, specificity of 96 %, PPV of 81 % and NPV of 94 %. CONCLUSION According to our results CA-FAST protocol proved to be a rapid bedside method, with good accuracy and high NPV in detection of ultrasonographic patterns suggestive of serious injury in trauma patients; moreover, the additional research of LCs did not cause a delay in the diagnosis. Ultrasonography should be used as initial investigation during the primary survey, sending to further diagnostic studies (CT scan) only those patients not clearly classified.

Abstract
OBJECTIVE Hemorrhage identification in trauma care is a major priority. Focused assessment in sonography for trauma (FAST) offers a rapid, reliable means of detecting torso bleeding. The aims of this study were to conduct a face, content, and construct validity assessment of a FAST simulator and establish a rigorous assessment tool. DESIGN Participants were requested to perform a FAST scan and state if any abnormality was found in each region. Metrics evaluated included time, errors, and missed targets. Accuracy of images obtained was assessed by 2 independent radiologists. Experts completed a face and content validity questionnaire at the end of the study. SETTING The study took place in the simulation suite within the Academic Surgical Unit of the Department of Surgery and Cancer. PARTICIPANTS Novices had no prior experience with ultrasound, intermediates had less than 6 months experience with fewer than 50 FAST scans performed, and experts had more than 1 year of experience with greater than 100 FAST scans performed. There were 31 participants: 11 experts, 10 intermediates, and 10 novices. RESULTS The face and content validity questionnaire scored high marks across all categories and achieved an overall median realism score of 8 ± 1.5 on a Likert scale. Experts performed the FAST scan faster with more accuracy and fewer errors than other cohorts (p < 0.001). Both the novices and intermediates were the slowest, least accurate, and either missed or made the most errors when scanning the lung bases and spleen. CONCLUSIONS This study has established the face, content, and construct validities of a FAST simulator, which could be used to accelerate training for novices. Additionally, it has demonstrated a rigorous method for FAST assessment, which has proven to be effective and in doing so addressed some of the criticisms leveled against it.

Abstract
ABSTRACT
Objectives:
To quantify the current availability and use of bedside emergency department ultrasonography (EDUS) for blunt trauma at Canadian pediatric centres and to identify any perceived barriers to the use of bedside EDUS in such centres.
Methods:
An electronic survey was sent to 162 pediatric emergency physicians and 12 site directors from the 12 pediatric emergency departments across Canada.
Results:
Ninety-two percent (11 of 12) of centres completed the survey. The individual physician response rate was 65% (106 of 162), with 100% of site directors responding. Ultrasound machines were available in 45% (5 of 11) of centres. Forty-two percent (32 of 77) of emergency physicians working in equipped pediatric centres used bedside EDUS to evaluate blunt abdominal trauma (BAT). In the subgroup of staff who also worked at adults sites, the frequency of ultrasonography use for the evaluation of pediatric BAT was 75%. In the 55% (6 of 11) of centres without ultrasonography, 88% of staff intend to incorporate its use in the future and 81% indicated that they believed the incorporation of ultrasonography would have a positive impact on patient care. The main perceived barriers to the use of ultrasonography in the evaluation of BAT were a lack of training (41%) and a lack of equipment (26%).
Conclusion:
Bedside EDUS is currently used in almost half of pediatric trauma centres, a frequency that is significantly lower than adult centres. Physicians in pediatric centres who use ultrasonography report that it has a high utility, and a great majority of physicians at pediatric centres without EDUS plan to incorporate it in the future. The main reported barriers to its use are a lack of training and a lack of equipment availability.

[PMID: 25498329 DOI: 10.1016/j.injury.2014.11.023] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2014] [Revised: 10/27/2014] [Accepted: 11/14/2014] [Indexed: 02/02/2023]
Abstract
INTRODUCTION The Focused Assessment with Sonography in Trauma examination (FAST) is currently taught and recommended in the ATLS(®), often as an addendum to the primary survey for patients with blunt abdominal trauma. Although it is non-invasive and rapidly performed at bedside, the utility of FAST in blunt abdominal trauma has been questioned. We designed this study to examine our hypothesis that FAST is not an efficacious screening tool for identifying intra-abdominal injuries. METHODS We performed a retrospective chart review of all patients with confirmatory diagnosis of blunt abdominal injuries with CT and/or laparotomy for a period of 1.5 years (from 7/2009 to 11/2010). FAST was performed by ED residents and considered positive when free intra-abdominal fluid was visualized. Abdominal CT, or exploratory laparotomy findings were used as confirmation of intra-abdominal injury. RESULTS A total of 1671 blunt trauma patients were admitted to and evaluated in the Emergency Department during a 1½ year period and 146 patients were confirmed intra-abdominal injuries by CT and/or laparotomy. Intraoperative findings include injuries to the liver, spleen, kidneys, and bowels. In 114 hemodynamically stable patients, FAST was positive in 25 patients, with a sensitivity of 22%. In 32 hemodynamically unstable patients, FAST was positive in 9 patients, with a sensitivity of 28%. A free peritoneal fluid and splenic injury are associated with a positive FAST on univariate analysis, and are the independent predictors for a positive FAST on multiple logistic regression. CONCLUSION FAST has a very low sensitivity in detecting blunt intraabdominal injury. In hemodynamically stable patients, a negative FAST without a CT may result in missed intra-abdominal injuries. In hemodynamically unstable blunt trauma patients, with clear physical findings on examination, the decision for exploratory laparotomy should not be distracted by a negative FAST.

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
Diagnostic imaging technology has advanced considerably during the past two decades. Different imaging techniques have been proposed for abdominal imaging in critically ill patients like plain radiography, sonography, computed tomography (CT), magnetic resonance and positron emission tomography. Sonography has been proven to be effective to detect free intra-peritoneal fluid and it is considered one of the primary diagnostic modalities for abdominal evaluation for trauma assessment. In our opinion sonography should replace other invasive techniques to rapidly triage blunt trauma patients with unstable vital signs and examine the peritoneal cavity as a site of major haemorrhage to expedite exploratory laparotomy. On the other hand, CT has become the imaging modality of choice in hemodynamically stable patients with multisystem blunt and penetrating trauma. New developments in the quantitative analysis of the CT images will improve our knowledge of pathophysiology, diagnostic and therapeutic management of abdominal pathologies in critically ill patients.

Abstract
The initial management of trauma patient is a critical period aiming at: stabilizing the vital functions; following a rigorous injury assessment; defining a therapeutic strategy. This management has to be organized to minimize loss of time that would be deleterious for the patients outcome. Thus, before patient arrival, the trauma team alert should lead to the initiation of care procedures adapted to the announced severity of the patient. Moreover, each individual should know its role in advance and the team should be managed by only one individual (the trauma leader) to avoid conflicts of decision. A rapid trauma injury assessment aims not only at guiding resuscitation (chest drainage, pelvic contention, to define the mean arterial pressure goal) but also to decide a critical intervention in case of hemodynamic instability (laparotomy, thoracotomy, arterial embolisation). This initial assessment includes a chest and a pelvic X-ray, abdominal ultrasound (extended to the lung) and transcranial Doppler (TCD). The whole body scanner with administration of intravenous contrast material is the cornerstone of the injury assessment but can be done for patients stabilized after the initial resuscitation.

Abstract
Background: Focused assessment with sonography for trauma (FAST) is an important skill during trauma resuscitation. Use of point of care ultrasound among the trauma team working in emergency care settings is lacking in India. Objective: To determine the accuracy of FAST done by nonradiologists (NR) when compared to radiologists during primary survey of trauma victims in the emergency department of a level 1 trauma center in India. Materials and Methods: A prospective study was done during primary survey of resuscitation of nonconsecutive patients in the resuscitation bay. The study subjects included NR such as one consultant emergency medicine, two medicine residents, one orthopedic resident and one surgery resident working as trauma team. These subjects underwent training at 3-day workshop on emergency sonography and performed 20 supervised positive and negative scans for free fluid. The FAST scans were first performed by NR and then by radiology residents (RR). The performers were blinded to each other's sonography findings. Computed tomography (CT) and laparotomy findings were used as gold standard whichever was feasible. Results were compared between both the groups. Intraobserver variability among NR and RR were noted. Results: Out of 150 scans 144 scans were analyzed. Mean age of the patients was 28 [1-70] years. Out of 24 true positive patients 18 underwent CT scan and exploratory laparotomies were done in six patients. Sensitivity of FAST done by NR and RR were 100% and 95.6% and specificity was 97.5% in both groups. Positive predictive value among NR and RR were 88.8%, 88.46% and negative predictive value were 97.5% and 99.15%. Intraobserver performance variation ranged from 87 to 97%. Conclusion: FAST performed by NRs is accurate during initial trauma resuscitation in the emergency department of a level 1 trauma center in India.

Abstract
BackgroundFocussed assessment with sonography in trauma (FAST) has assumed a key role in the rapid non-invasive assessment of thoracoabdominal trauma and assists in decreasing disposition time. This study evaluates FAST's efficacy with respect to haemodynamic stability in a South African emergency department (ED).MethodsData were collected prospectively by four emergency medicine doctors trained in emergency ultrasonography. FAST scans were performed by one ED doctor and timings, scan result and disposition were recorded. Patient haemodynamic stability was assessed by the emergency doctor performing the scan; subjectively at the time of scanning and objectively using calculation of the shock index. All scan results were subsequently verified by a second ED doctor in a blinded fashion and by CT scanning or operative intervention when clinically indicated.Results166 FAST scans were conducted of which 36 (21.7%) were positive. Mean age was 30.6 years (SD 12.8). 74.1% of patients sustained blunt traumatic injury. Doctors’ subjective haemodynamic stability assessments had higher specificity, sensitivity and predictive values than shock index alone. Haemodynamic instability and a positive FAST result were significantly related (p=0.004). Sensitivities and specificities of FAST scans for blunt and penetrating trauma were 93.1% and 100%, and 90.0% and 100%, respectively. Corresponding values for pneumothoraces were 84.6% and 100%.DiscussionThis study showed a valuable role for FAST in all traumas, particularly in haemodynamic compromise. As an addition to the physician's repertoire of bedside assessment tools, it improves diagnostic capabilities in comparison with simple haemodynamic assessments alone.

Abstract
BACKGROUND Hospitals have a critically important role in the management of mass causality incidents (MCI), yet there is little information to assist emergency planners. A significantly limiting factor of a hospital's capability to treat those affected is its surgical capacity. We therefore intended to provide data about the duration and predictors of life saving operations. METHODS The data of 20,815 predominantly blunt trauma patients recorded in the Trauma Registry of the German-Trauma-Society was retrospectively analyzed to calculate the duration of life-saving operations as well as their predictors. Inclusion criteria were an ISS≥16 and the performance of relevant ICPM-coded procedures within 6h of admission. RESULTS From 1,228 patients fulfilling the inclusion criteria 1,793 operations could be identified as life-saving operations. Acute injuries to the abdomen accounted for 54.1% followed by head injuries (26.3%), pelvic injuries (11.5%), thoracic injuries (5.0%) and major amputations (3.1%). The mean cut to suture time was 130min (IQR 65-165min). Logistic regression revealed 8 variables associated with an emergency operation: AIS of abdomen ≥3 (OR 4,00), ISS ≥35 (OR 2,94), hemoglobin level ≤8 mg/dL (OR 1,40), pulse rate on hospital admission <40 or >120/min (OR 1,39), blood pressure on hospital admission <90 mmHg (OR 1,35), prehospital infusion volume ≥2000 ml (OR 1,34), GCS ≤8 (OR 1,32) and anisocoria (OR 1,28) on-scene. CONCLUSIONS The mean operation time of 130min calculated for emergency life-saving surgical operations provides a realistic guideline for the prospective treatment capacity which can be estimated and projected into an actual incident admission capacity. Knowledge of predictive factors for life-saving emergency operations helps to identify those patients that need most urgent operative treatment in case of blunt MCI.
