Abstract
PURPOSE Early detection of bleeding is important for managing trauma cases in the emergency department (ED). Several trauma suites are equipped with computed tomography (CT) scanners to reduce the time to CT. In the last decade, sliding gantry CT has been implemented in trauma suites, highlighting conventional techniques' advantages. We investigated the change in the time to CT and the challenges faced during the implementation. METHODS Trauma suite treatments with a conventional CT scanner between January and December 2016 formed the control group. From January to April 2017, trauma suites were modified, and treatment was outsourced to an interim trauma suite. By May 2017, trauma suites were equipped with a sliding gantry CT scanner. Treatments from May to July 2017 formed the transition group, and those from August to December 2017 formed the routine use group. We evaluated the time to CT in all groups and considered the reasons for the delays in the transition and routine use groups. RESULTS On sliding gantry CT implementation, although time to CT remained unaffected in the transition group, it significantly reduced in the routine use group, independent of injury severity score. The incidence of cable management problems was significantly higher in the latter group. CONCLUSIONS We have demonstrated a decrease in the time to CT with the implementation of a sliding gantry CT. However, due to a higher number of cable management problems in the routine use group, we recommend regular refresher team training with routine use.

Abstract
Introduction The abdomen is one of the most frequently damaged areas in trauma patients and is commonly encountered in road traffic accidents (RTAs). The present study evaluates the frequency, etiology, causation, and form of injury in blunt abdominal trauma (BAT) cases who had autopsies. Method An autopsy-based observational prospective study was conducted at the Department of Forensic Medicine and Toxicology, Nalanda Medical College and Hospital Patna, India, during the period from October 2018 to September 2020, which included a total of 940 autopsy cases showing blunt abdominal injuries. A predesigned proforma for the postmortem evaluation of BAT victims was used to collect the required information on the cases. Descriptive statistics were performed, and the data were presented as frequency (%) and mean±SD. Chi-square tests were performed to compare categorical variables between groups. Results BAT accounted for 120 (12.76%) cases of all autopsies performed. The majority of victims were male (92.48%). Victims aged 21-30 years (31, 25.83%) were the ones most usually engaged in BAT cases. Among the mechanisms accountable for BAT, RTAs were the most common (99, 82.50%), followed by assault (16, 13.30%). In most of the cases, the liver was injured (107, 89.16%), followed by the spleen (60, 50.00%) and kidney (24, 20.00%). The majority of blunt abdominal injury-related deaths were accidental (100, 83.33%), followed by homicidal (15, 12.5%) and suicidal cases (5, 4.17%). Hemorrhage and neurogenic shock were the most prevalent causes of mortality, particularly if the individual died within a few hours. Conclusion RTAs are the most frequent cause of BAT in autopsy cases, and the liver is the most affected organ. The majority of deaths occur within the first 24 hours of injury. Since blunt abdominal injuries have the propensity to increase morbidity and mortality, appropriate emphasis on their precise diagnosis and satisfactory therapy is mandated.

Accuracy of Focused Assessment with Sonography for Trauma (FAST) in Blunt Abdominal Trauma. Emerg Med Int 2022; 2022:8290339. [PMID: 36247707 PMCID: PMC9568351 DOI: 10.1155/2022/8290339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Accepted: 09/27/2022] [Indexed: 11/21/2022] Open
Abstract
Purpose This study aimed to evaluate the accuracy and outcomes of focused assessment with sonography for trauma (FAST) and determine the factors associated with true-positive FAST results. Methods The FAST results from 2016 to 2020 were retrospectively reviewed. Cases involving penetrating injury, transfer from other hospitals, age ≤ 16 years, prehospital arrest, and no confirmatory test were excluded. Intra-abdominal fluid was confirmed using computed tomography or operative findings. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. Demographic data, injury characteristics, and outcomes were compared between true-positive and false-negative results. Logistic regression was used to identify the factors associated with true-positive results. Results Of 2,758 patients, 163 and 2,595 patients showed positive and negative results, respectively. True positives were 135 and true negatives were 2325. The overall sensitivity, specificity, PPV, and NPV were 33.3%, 98.8%, 82.8%, and 89.6%, respectively. The sensitivity increased to 49.1% in patients with initial systolic blood pressure (SBP) ≤ 90 mmHg. The true-positive group showed a lower SBP and Glasgow Coma Scale score and a higher laparotomy rate than the false-negative group. However, mortality showed no significant difference. In logistic regression analysis, hollow viscus injury (1.820 [1.123–2.949], P=0.015) and the lowest SBP (0.988 [0.980–0.997], P=0.009) were associated with true-positive results compared to false-negative results. Conclusion The overall sensitivity of FAST was low; therefore, it should be performed in selected patients such as SBP ≤ 90 mmHg. Because of its low sensitivity and no influence on outcome, physicians should not rely solely on FAST.

Seat belt syndrome is caused by a different mechanism: A case report. Int J Surg Case Rep 2022; 98:107509. [PMID: 36007407 PMCID: PMC9424340 DOI: 10.1016/j.ijscr.2022.107509] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Revised: 08/08/2022] [Accepted: 08/11/2022] [Indexed: 11/20/2022] Open
Abstract
Introduction and importance Seat belt syndrome is associated with multiple visceral injuries and vertebral burst fractures. Small Intestinal perforations are seen in 5–15 % of blunt abdominal trauma. In our case, we will report a case that presented small intestinal perforation and thoracic vertebral fracture caused by a different mechanism. Case presentation Previously healthy 48-year-old male presented to the emergency department following falling from 15 feats height. He was a paraplegic with a sensory level at T12. He did not have a clinical feature of spinal shock. He was complaining of epigastric and central abdominal pain and tenderness and was diagnosed to have a proximal Jejunal perforation associated with an unstable fracture of T12 causing spinal compression. Open intestinal repair followed by a posterior spinal exploration and pedicle screw fixation done. Clinical discussion Violent injury due to different mechanisms can have similar injuries to Seat belt syndrome. Ultrasonography is used to detect pneumoperitoneum, but the Contrast study is the gold standard to detect visceral injuries. The surgical approach to visceral injury depends on the patient's condition. But the laparoscopic approach has a more favorable postoperative outcome than open access. Conclusion Intestinal perforations associated with the neurological deficit are difficult to identify in an initial clinical assessment. Thoracolumbar fractures can associate with small bowel injuries during high-velocity trauma. Early identification and repair of the intestinal injury are important to prevent devastating complications and to improve neurological recovery after spinal surgery. Seat belt syndrome is associated with a characteristic set of visceral injuries and spinal fractures. Violent injuries caused by a different mechanism can cause similar injuries to Seat belt syndrome. Thorough clinical examination with ultrasonography and contrast studies helps to detect visceral injuries.

Abstract
Background, The context
A prospective study was conducted involving 81 patients (mean age, 20.79 years) with abdominal trauma who underwent ultrasonography and post-contrast CT on MDCT scanner. The total DLP for each patient was reviewed, and the effective dose was calculated. Purpose of the study to: explore the role of MDCT in assessing traumatic abdominal lesions, demonstrate radiation dose delivered by MDCT, and describe specific CT technical features to minimize radiation.
Results
The spleen was the most commonly injured organ (49.4%) followed by liver (39.5%) and kidney (24.7%). Pancreatic injury occurred in seven patients, whereas only two patients had intestinal injuries. One patient had adrenal injury. Minimal, mild and moderate free intra-peritoneal fluid collection was detected in 21 (25.9%), 47 (58%) and 10 (12.3%) patients, respectively. Only three (3.7%) patients had no collection. One patient had active uncontrolled bleeding and died. Radiation dose was below the detrimental level (calculated effective dose), with optimal image quality.
Conclusions
MDCT is sensitive to all types of traumatic abdominal lesions. Not only in determining the injury, but also in its grading. MDCT has affected the treatment directions, spotting a focus on conservative treatment by raising the diagnostic confidence.
FAST cannot be the sole imaging modality. The individual radiation risk is small but real. Advancements in medical imaging reduce radiation risk.

Abstract
This study details the etiology, frequency and effect of abdominal vascular injuries in patients after polytrauma based on a large registry of trauma patients. The impact of arterial, venous and mixed vascular injuries on patients' outcome was of interest, as in particular the relevance of venous vessel injury may be underestimated and not adequately assessed in literature so far. All patients of TraumaRegister DGU with the following criteria were included: online documentation of european trauma centers, age 16-85 years, presence of abdominal vascular injury and Abbreviated Injury Scale (AIS) ≥ 3. Patients were divided in three groups of: arterial injury only, venous injury only, mixed arterial and venous injuries. Reporting in this study adheres to the STROBE criteria. A total of 2949 patients were included. All types of abdominal vessel injuries were more prevalent in patients with abdominal trauma followed by thoracic trauma. Rate of patients with shock upon admission were the same in patients with arterial injury alone (n = 606, 33%) and venous injury alone (n = 95, 32%). Venous trauma showed higher odds ratio for in-hospital mortality (OR: 1.48; 95% CI 1.10-1.98, p = 0.010). Abdominal arterial and venous injury in patients suffering from severe trauma were associated with a comparable rate of hemodynamic instability at the time of admission. 24 h as well as in-hospital mortality rate were similar in in patients with venous injury and arterial injury. Stable patients suspected of abdominal vascular injuries should be further investigated to exclude or localize the possible subtle venous injury.

Abstract
Objective: The number of accident cases is increasing day by day, so as the challenges. With an emphasis on trauma care, the government started a 120 bedded level I trauma centre in northern India catering to a population of 2.8 million in June 2018. Through this article, we aimed to share our experience of blunt abdominal trauma management from a new level I trauma centre.
Material and Methods: In this retrospective observational study, historical analysis of all available records from July 2018 to March 2020 was done. Inclusion criteria included blunt trauma abdomen with or without associated injuries. Data regarding age, sex, mechanism of injury, time taken to reach the hospital, the pattern of solid organs and hollow viscus injuries, associated extra abdominal injuries, mode of treatment, complications, length of ICU and hospital stay, and mortality were reviewed.
Results: Overall, 154 cases sustained abdominal injuries during the study period. Seventy-five percent were male. The most common cause of blunt trauma abdomen was road traffic crashes. Operative management was required in 57 (37.01%) cases while 97(62.98%) were managed non-operatively (NOM). Mean ICU stay was 05.73 days, while the average hospital stay was 12 days (range 10-60 days). Procedures performed included splenectomy, liver repair, primary closure of bowel injury, and stoma formation. Complications occured in 16.88% cases and the overall mortality rate was 11.68%.
Conclusion: The study revealed that among 154 cases of fatal blunt abdominal trauma, road traffic crash was the most common cause of blunt abdominal trauma, predominantly affecting males. The visceral and peritoneal injury frequently perceived was liver in 40 cases (25.9%), spleen 66 (43%), intestine 21(13.6%) and kidney 13 cases (09%). Abdominal injury was associated with other injuries like head, chest and extremity injuries in 52.5% cases. Duration of injury, presence of associated injury and preoperative ventilation requirement were independent predictors of mortality apart from contributary factors such as clinical presentation, organ involved and presence of complications.

Abstract
BACKGROUND Assessment and triage in an austere environment represent a major challenge in casualty care. Modern conflicts involve a significant proportion of multiple wounds, either superficial or penetrating, which complicate clinical evaluation. Furthermore, there is often poor accessibility to computed tomography scans and a limited number of surgical teams. Therefore, ultrasound (US) represents a potentially valuable tool for distinguishing superficial fragments or shrapnels from penetrating trauma requiring immediate damage-control surgery. METHODS This retrospective observational multicenter study assessed casualties treated for 8 months by five medical teams deployed in Africa and Middle East. Two experts, who were experienced in military emergency medicine but did not take part in the missions, carried out an independent analysis for each case, evaluating the contribution of US to the following five items: triage categorization, diagnosis, clinical severity, prehospital therapeutic choices, and priority to operation room. Consensus was obtained using the Delphi method with three rounds. RESULTS Of 325 casualties, 189 underwent US examination. The mean injury severity scale score was 25.6, and 76% were wounded by an improvised explosive device. Ultrasound was useful for confirming (23%) or excluding (63%) the suspected diagnosis made in the clinical assessment. It also helped obtain a diagnosis that had not been considered for 3% of casualties and was responsible for a major change in procedure or therapy in 4%. Ultrasound altered the surgical priority in 43% of cases. For 30% of cases, US permitted surgery to be temporarily delayed to prioritize another more urgent casualty. CONCLUSION Ultrasound is a valuable tool for the management of mass casualties by improving treatment and triage, especially when surgical resources are limited. In some situations, US can also correct a diagnosis or improve prehospital therapeutic choices. Field medical teams should be trained to integrate US into their prehospital protocols. LEVEL OF EVIDENCE Case series (no criterion standard), level V.

Abstract
BACKGROUND The liver is the second most injured organ following blunt abdominal trauma (BAT) after the spleen. Although the computed tomography (CT) scan is considered as the gold standard for diagnosing liver injury in BAT, it may not readily available in all the hospitals. This study was performed to evaluate the role of aspartate transaminase (AST) and alanine transaminase (ALT) in patients with BAT and its significance in predicting the diagnosis and severity of the liver injury. METHOD The study was conducted in Chitwan Medical College Teaching Hospital (CMCTH) from February 2019 to May 2020. It was a prospective observational study. All the patients with BAT were received by on-duty surgical residents in the emergency department. Based on the imaging and operative finding, patients with liver injury and without liver injury were noted with the associated injury. For comparisons of clinical and grading characteristics between the two groups (liver injury and no liver injury), the chi-squared test was used for categorical variables as appropriate, and the Mann-Whitney U test used for quantitative variables (AST and ALT). The comparisons between more than two groups (grade of injury) were performed using the Kruskal-Wallis test. The receiver operating characteristic (ROC) was used to calculate the optimal cut-off value of AST and ALT. RESULTS Among the 96 patients admitted with BAT, 38 patients had liver injury and 58 patients had no liver injury. The median length of the intensive care unit (ICU) stay of patients with liver injury was higher than without liver injury. There was a significant difference in the median level of AST and ALT (< 0.001) between patients with liver injury and no liver injury. The area under the ROC curve of AST was 0.89 (95% confidence interval 0.86-0.98) and of ALT was 0.92 (95% confidence interval 0.83-0.97). The area under the curve demonstrated that the test was a good predictor for the identification of liver injury and also the severity of liver enzymes. The cut-off values for the liver injury were 106 U/l and 80 U/l for AST and ALT, respectively. Based on these values, AST ≥ 106 U/l had a sensitivity of 71.7%, a specificity of 90%, a positive predictive value of 86.8%, and a negative predictive value of 77.6%. The corresponding values for ALT ≥ 80 U/l were 77.8%, 94.1%, 92.1%, and 82.8%, respectively. CONCLUSION In conclusion, we report the optimal cut-off value of AST and ALT for liver injury in BAT as ≥ 106 U/l and 80 U/l, respectively. The elevated level of AST and ALT might assist the emergency physicians and surgeons to timely refer the suspected patients with the liver injury to a tertiary center.

Abstract
PURPOSE Hemoperitoneum in the hypotensive trauma patient is an indication for emergent laparotomy. Focused assessment sonography in trauma (FAST) is a widely used tool for detecting hemoperitoneum. The usefulness of FAST is currently limited by low sensitivity. We hypothesize rolling patients onto their right side will pool small volumes of fluid into the right upper quadrant of the abdomen leading to increased sensitivity. METHODS Peritoneal dialysis patients were recruited for voluntary participation in a small pilot prospective clinical trial. Each participant first underwent a supine FAST followed by a 30-second roll onto the right side. Once back in the supine position, the FAST was repeated (FASTeR or FAST examination after right-sided roll). About 50 mL aliquots of dialysate were sequentially infused into the abdomen and the imaging sequence repeated until a positive finding was obtained. RESULTS Seven patients were consented for the study. One patient was found to have an equivocal examination secondary to renal cysts. All six remaining participants converted to a positive FASTeR at an intra-abdominal fluid volume at which standard FAST was negative. CONCLUSIONS Rolling patients to the right side increased FAST sensitivity, converting false-negative to true positives examinations. A larger study is needed to validate our preliminary data.

Abstract
OBJECTIVE Focused assessment with sonography in trauma (FAST) examination is a widely known initial evaluation for patients with trauma. However, it remains unclear whether FAST contributes to patient survival in patients with haemodynamically stable trauma. In this study, we compared in-hospital mortality and length of stay between patients undergoing initial FAST vs initial CT for haemodynamically stable torso trauma. METHODS This was a retrospective cohort study using data from 264 major emergency hospitals in the Japan Trauma Data Bank between 2004 and 2016. Patients were included if they had torso trauma with a chest or abdomen abbreviated injury scale score of ≥3 and systolic blood pressure of ≥100 mm Hg at hospital arrival. Eligible patients were divided into those who underwent initial FAST and those who underwent initial CT. Multivariable logistic regression analysis for in-hospital mortality and multivariable linear regression for length of stay were performed to compare the initial FAST and initial CT groups with adjustment for patient backgrounds while also adjusting for within-hospital clustering using a generalised estimating equation. RESULTS There were 9942 patients; 8558 underwent initial FAST and 1384 underwent initial CT. Multivariable logistic regression showed no significant difference in in-hospital mortality between the initial FAST and initial CT groups (OR 1.37, 95% CI 0.94 to 1.99, p=0.10). Multivariable linear regression revealed that the initial FAST group had a significantly longer length of stay than the initial CT group (difference: 3.5 days; 95% CI 1.0 to 5.9, p<0.01). CONCLUSIONS In-hospital mortality was not significantly different between the initial FAST and initial CT groups for patients with haemodynamically stable torso trauma. Initial CT should be considered in patients with haemodynamically stable torso trauma.

Abstract
Background: Focused assessment with sonography in trauma (FAST) being a rapid noninvasive examination is used primarily to evaluate for the evidence of traumatic free fluid suggestive of injury in the peritoneal, pericardial, and pleural cavities. It is widely recognized as a mainstream emergency skill in the management of trauma. Aim: The aim of the study is to evaluate the accuracy of FAST in patients presenting with blunt abdominal trauma. Methods: Data were collected prospectively from FAST scans conducted in blunt trauma abdomen (BTA) patients. Positive and negative FAST scans were confirmed either with contrast-enhanced computed tomography (CECT) abdomen or with exploratory laparotomy, thus dividing it further into four groups, i.e., true-positive, false-positive, true-negative, and false-negative scans. After collecting the data, accuracy of FAST was calculated. Results: In this study, a total of 104 patients were included. The mean age was 38.17 years. Most common cause of BTA was road traffic accident. The overall sensitivity, specificity, and accuracy of FAST were 69.8%, 92.1%, and 80.8%, respectively. Conclusion: This study showed that FAST is of paramount importance in patients who are hemodynamically unstable as it has a high positive predictive value. However, a FAST-negative result should always be confirmed by other modalities.

Abstract
ABSTRACTFocused assessment with sonography for trauma (FAST) has been incorporated into the initial evaluation of trauma for decades. It is an important screening tool in the detection of intra-abdominal fluid. The objective of this study was to perform a systematic review of the use and accuracy of FAST as an imaging tool for blunt abdominal trauma in disaster/mass casualty settings. A systematic review of literature was conducted using key words and search terms. Two independent reviewers screened abstracts to determine inclusion using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS). For studies passing QUADAS, a meta-analysis was performed calculating sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). FAST results were compared with the gold standard, which was a combination of CT scan results, operative findings, and medical records of the clinical course. Initial database screening resulted in 133 articles, of which 21 were selected for QUADAS evaluation. Five studies passed QUADAS and were selected in the final meta-analysis, with a total of 4263 patients. The sensitivity of FAST was 92.1% (87.8–95.6), specificity 98.7% (96.0–99.9), PPV 90.7% (70.0–98.0), and NPV 98.8% (98.1–99.5) for the detection of intra-abdominal injury. In our meta-analysis, FAST was both sensitive and specific in the evaluation of trauma in the disaster setting.

Abstract
BACKGROUND Point-of-care ultrasound has gained widespread use in developing countries due to decreased cost and improved telemedicine capabilities. Ultrasound training, specifically image acquisition skills, is occurring with more frequency in non-medical personnel with varying educational levels in these underdeveloped areas. This study evaluates if students without a high school education can be trained to acquire useful FAST images, and to determine if an 8th grade student can teach peers these skills. METHODS The 8th grade students at a small middle school were divided into two groups. One group received training by a certified medical sonographer, while the other group received training by a peer 8th grade student trainer who had previously received training by the sonographer. After training, each student was independently tested by scanning the four FAST locations. A blinded ultrasound expert evaluated these images and deemed each image adequate or inadequate for clinical use. RESULTS Eighty video image clips were obtained. The overall image adequacy rate was 74%. The splenorenal window had the highest rate at 95%, followed by retrovesical at 90%, hepatorenal at 75%, and subxiphoid cardiac at 35%. The adequacy rate of the sonographer-trained group was 78%, while the adequacy rate of the student-trained group was 70%. The difference in image adequacy rate between the two groups was not significant (P-value 0.459). CONCLUSION The majority of 8th graders obtained clinically adequate FAST images after minimal training. Additionally, the student-trained group performed as well as the sonographer-trained group.

Abstract
Objectives: To determine the diagnostic accuracy of Focused Assessment with Sonography for Trauma (FAST) in blunt abdominal trauma caused by motor vehicle accidents at our Hospital in Dhahran city. Methods: This descriptive, observational study was conducted in the Radiology Department at King Fahad Military Medical Complex Dhahran, Saudi Arabia between September 2016 and September 2017. All adult patients (n=105) involved in motor vehicle accidents with blunt abdominal injury on presentation were retrospectively reviewed for FAST and CT scans for detection of free fluid. Focused assessment with sonography for trauma studies were conducted or supervised by senior registrar of general surgery (trauma team leader). Computed tomography findings were reviewed by 2 experienced radiologists. High and low-grade solid abdominal visceral (liver, spleen, kidney) injuries were identified on CT scans. Focused assessment with sonography for trauma and CT scan findings were identified as ‘positive’ and ‘negative’ for presence and absence of free fluid respectively. Outcomes of FAST were presented on a 2x2 contingency table. Results: Sensitivity of FAST in detecting intraperitoneal free fluid was calculated as 76.1% (95% confidence interval [CI], 64.14-85.69%), specificity 84.2% (95% CI, 68.75-93.98%) and accuracy 79% (95% CI, 70.01-86.38%). Focused assessment with sonography for trauma detected free fluid in most cases of high-grade solid visceral injuries. Nearly half of true-negative cases were having low grade visceral or other injuries. Conclusion: Focused assessment with sonography for trauma is an important tool in initial assessment of suspected blunt abdominal injury patients with high sensitivity and specificity. A negative FAST does not exclude low grade solid visceral or other injuries.

Abstract
AbstractIntroductionPoint-of-Care Ultrasound (POCUS) has become an important diagnostic tool for hospital-based clinicians. This study assesses the role of POCUS at Pemberton Music Festival 2016 (Pemberton, British Columbia [BC], Canada), a remote mass gathering where physicians face limited resources, complex disposition decisions, and a dynamic clinical environment.ObjectivesThis study prospectively evaluated the impact of POCUS on patient diagnosis, management, and disposition based on the self-report of the study physicians. The authors hypothesized that having ultrasound available for use would aid in diagnostic and management decisions and would reduce the need to transfer patients off-site to other health care facilities, reducing impact on the acute health services in the host community.MethodsA handheld ultrasound was available for use by physicians in the main medical tent. All participating physicians self-reported their training and comfort using POCUS. After each POCUS scan, physicians completed a survey and recorded the indication for use, scans performed, and impact on patient diagnosis, management, and disposition.ResultsIn total, POCUS was used on 28 of the 686 patients treated in the main medical tent; POCUS was reported to narrow the differential diagnosis in 64% of cases and altered the working diagnosis in 21% of cases. Its use changed the management plan in 39% of patients. Its use was reported to reduce the burden on broader health care resource utilization in 46% of cases and prevented ambulance transport off-site in 32% of cases (nine cases in total). This corresponded to an absolute risk reduction of 1.3% for the percentage of patients transferred to hospital (PPTH; relative risk reduction of 53%).Conclusion:Physicians reported that POCUS improved the diagnosis, management, and disposition of select patients at a remote, multi-day music festival. Also, POCUS reduced ambulance transfers off-site and reduced the perceived burden on broader health care utilization.PragerR, SedgwickC, LundA, KimD, HoB, StachuraM, GutmanS.

Abstract
Most emergency department (ED) physicians implement the Advanced Trauma Life Support (ATLS) approach, including primary and secondary survey, for the assessment of blunt abdominal trauma (BAT) patients. This report emphasizes the need for repeat Focused Assessment with Sonography for Trauma (FAST) and abdominal computed tomography (CT) if a BAT patient's condition persists or worsens. After initial negative FAST and abdominal CT findings, it is recommended that BAT patients with suspected intraabdominal injury should receive repeat examination in an optimal time. We report a patient who sustained duodenal perforation following BAT diagnosed by repeat ultrasound examination and abdominal CT scan. (Hong Kong j.emerg.med. 2014;21:396-399)

Abstract
BACKGROUND Splenic injury is the leading cause of major bleeding after blunt abdominal trauma. We examined the clinical and radiological presentations, management, and outcome of blunt splenic injuries (BSI) in our institution. MATERIAL AND METHODS A retrospective study of BSI patients between 2011 and 2014 was conducted. We analyzed and compared management and outcome of different splenic injury grades in trauma patients. RESULTS A total of 191 BSI patients were identified with a mean (SD) age of 26.9 years (13.1); 164 (85.9%) were males. Traffic-related accident was the main mechanism of injury. Splenic contusion and hematoma (77.2%) was the most frequent finding on initial computerized tomography (CT) scans, followed by shattered spleen (11.1%), blush (11.1%), and devascularization (0.6%). Repeated CT scan revealed 3 patients with pseudoaneurysm who underwent angioembolization. Nearly a quarter of patients were managed surgically. Non-operative management failed in 1 patient who underwent splenectomy. Patients with grade V injury presented with higher mean ISS and abdominal AIS, required frequent blood transfusion, and were more likely to be FAST-positive (p=0.001). The majority of low-grade (I-III) splenic injuries were treated conservatively, while patients with high-grade (IV and V) BSI frequently required splenectomy (p=0.001). Adults were more likely to have grade I, II, and V BSI, blood transfusion, and prolonged ICU stay as compared to pediatric BSI patients. The overall mortality rate was 7.9%, which is mainly association with traumatic brain injury and hemorrhagic shock; half of the deaths occurred within the first day after injury. CONCLUSIONS Most BSI patients had grade I-III injuries that were successfully treated non-operatively, with a low failure rate. The severity of injury and presence of associated lesions should be carefully considered in developing the management plan. Thorough clinical assessment and CT scan evaluation are crucial for appropriate management of BSI.

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
PURPOSE This study aimed to determine any association between positive findings in ultrasonography examination and initial BD value with regard to diagnosis of intra-abdominal bleeding following blunt abdominal trauma. METHODS A prospective, multi-center study of consecutive adult patients was performed from April to September 2015. Demographics, initial vital signs and arterial BD were evaluated with respect to presence of any association with intra-abdominal bleeding and in-hospital mortality. FAST study was performed to find intra-abdominal bleeding. Receiver operating characteristic (ROC) curves tested the ability of BD to identify patients with intra-abdominal hemorrhage and probable mortality. RESULTS A total of 879 patients were included in final analysis. The mean (SD) age was 36.68 (15.7) years and 714 patients (81.2%) were male. According to multivariable analysis, statistically significant association was observed between negative admission BD and both intra-abdominal bleeding (OR 3.48, 95% CI 2.06-5.88, p<0.001) and in-hospital mortality (OR 1.55, 95% CI 1.49-1.63, p<0.001). ROC curve analysis demonstrated sensitivity of 92.7% and specificity of 22.1% for the best cut-off value of BD (-8mEq/L) to diagnose internal hemorrhage. Further, a cut-off value of -7mEq/L demonstrated significant predictive performance, 94.8% sensitivity and 53.6% specificity for in-hospital mortality. CONCLUSION This study revealed that arterial BD is an early accessible important marker to identify intra-abdominal bleeding, as well as to predict overall in-hospital mortality in patients with blunt abdominal trauma.

Abstract
BACKGROUND Previous work proposed a Massive Transfusion Score (MTS) calculated from values obtained in the emergency department to predict likelihood of massive transfusion (MT). We hypothesized the MTS could be used at Hour 6 to differentiate who continues to require balanced resuscitation in Hours 7 to 24 and to predict death at 28 days. METHODS We prospectively enrolled patients in whom the MT protocol was initiated from 2005 to 2011. Data including timing of blood products were determined at Hours 0, 6, 12, and 24. For each patient, transfusion needs were defined based on either an inappropriately low hemoglobin response to transfusion or a hemoglobin decrease of greater than 1 g/dL if no transfusion. Timing and cause of death were used to account for survivor bias. Multivariate logistic regression was used to determine independent predictors of outcome. RESULTS A total of 190 MT protocol activations were included, and by Hour 6, 61% required 10 U or greater packed red blood cells. Calculated at initial presentation, a revised MTS (systolic blood pressure < 90 mm Hg, base deficit ≥ 6, temperature < 35.5°C, international normalized ratio > 1.5, hemoglobin < 11 g/dL) was superior to the original MTS (including heart rate ≥ 120 beats per minute, Focused Assessment With Sonography in Trauma [FAST] status, mechanism) or the Assessment of Blood Consumption (ABC) score for predicting MT (area under the curve [AUC] MT at 6 hours, 0.68; 95% confidence interval [CI], 0.57-0.79; at 24 hours, 0.72; 0.61-0.83; p < 0.05). For those alive at Hour 6, the revised MTS was predictive of future packed red blood cell need (AUC, 0.87) in Hours 7 to 12, 24-hour mortality (AUC, 0.95), and 28-day mortality (AUC, 0.77). For each additional positive trigger of the MTS at Hour 6, the odds of death at 24 hours and 28 days were substantially increased (24-hour odds ratio, 4.6; 95% CI, 2.3-9.3; 28-day odds ratio, 2.2; 95% CI, 1.5-3.2; p < 0.0001). CONCLUSION Early end points of resuscitation adopted from the components of the revised MTS are predictive of ongoing transfusion. Failure to normalize these components by Hour 6 portends a particularly poor prognosis. LEVEL OF EVIDENCE Prognostic study, level 3.

Abstract
CLINICAL/METHODOLOGICAL ISSUE The acute radiological diagnostics of polytrauma patients has become an essential part of the interdisciplinary treatment in the emergency room. The incidence of polytrauma patients with an injury severity score (ISS) >16 is approximately 450 cases/million inhabitants/year in Europe. Injuries of the parenchymal organs are of utmost importance for the prognosis and treatment of these patients. The injury patterns are complex and a great deal of experience is necessary to be able to obtain the correct diagnosis within minutes. This review article deals with the radiological diagnostics and grading of the severity of injuries to the spleen, liver, pancreas and kidneys. STANDARD RADIOLOGICAL METHODS The use of ultrasound for the evaluation of polytraumatized patients will be discussed. The most important trauma-associated findings for the above mentioned organs using multidetector computed tomography (MDCT) will be described and illustrated by dedicated case findings. METHODOLOGICAL INNOVATIONS Ultrasound contrast agents can supply valuable, additional diagnostic information in the evaluation of polytraumatized patients. Computed tomography has become established as the most relevant imaging modality in severe trauma. Innovative organ-adapted and contrast application protocols improve the diagnostic performance of MDCT. PRACTICAL RECOMMENDATIONS The use of focused assessment sonography for trauma (FAST) scanning as a screening tool is in agreement with the other clinical disciplines of the trauma team. The use of MDCT is trauma-dependent and the classification of the severity of the different parenchymal organ injuries is ultimately decisive for further treatment and prognosis of trauma victims.

Abstract
A young female was brought into the emergency department with pulseless electrical activity (PEA) after local resection of neurofibromateous lesions. Chest ultrasonography was normal. Abdominal ultrasonography was not performed. After successful resuscitation a total body CT-scan was performed to rule out potential bleeding sources. However, haemodynamic instability reoccurred and the scan had to be aborted at the thoracoabdominal level. No thoracic abnormalities were found. Resuscitation was reinitiated and abdominal ultrasonography was performed, showing a large amount of abdominal fluid. A progressive fall in haemoglobin was noted. Emergency laparotomy was performed, revealing a large retroperitoneal haematoma. Despite ligation and packing, bleeding continued. Postoperative angiography showed active bleeding from a branch of the left internal iliac artery, which could be successfully coiled. Unfortunately, the patient died five days later due to irreversible brain damage. Revision of an MRI scan made one year earlier showed a 10 cm large retroperitoneal neurofibromatous lesion exactly at the location of the current bleeding. This case shows that patients with neurofibromatosis might develop spontaneous life-threatening bleeding from retroperitoneal located lesions. Furthermore, it points out the necessity of focused assessment with ultrasonography of the abdomen in all patients with PEA of unknown origin.

Abstract
PURPOSE OF REVIEW This article reviews the latest operative trauma surgery techniques and strategies, which have been published in the last 10 years. Many of the articles we reviewed come directly from combat surgery experience and may be also applied to the severely injured civilian trauma patient and in the context of terrorist attacks on civilian populations. RECENT FINDINGS We reviewed the most important innovations in operative trauma surgery; the use of ultrasound and computed tomography in the preoperative evaluation of the penetrating trauma patient, the use of temporary vascular shunts, the current management of military wounds, the use of preperitoneal packing in pelvic fractures and the management of the multiple traumatic amputation patient. SUMMARY The last 10 years of conflict has produced a wealth of experience and novel techniques in operative trauma surgery. The articles we review here are essential for the contemporary care of the severely injured trauma patient, whether they are card for in a level 1 trauma center or in a field hospital at the edge of a battlefield.

Abstract
Focused assessment with sonography for trauma (FAST) is a limited ultrasound examination, primarily aimed at the identification of the presence of free intraperitoneal or pericardial fluid. In the context of blunt trauma abdomen (BTA), free fluid is usually due to hemorrhage, bowel contents, or both; contributes towards the timely diagnosis of potentially life-threatening hemorrhage; and is a decision-making tool to help determine the need for further evaluation or operative intervention. Fifty patients with blunt trauma abdomen were evaluated prospectively with FAST. The findings of FAST were compared with contrast-enhanced computed tomography (CECT), laparotomy, and autopsy. Any free fluid in the abdomen was presumed to be hemoperitoneum. Sonographic findings of intra-abdominal free fluid were confirmed by CECT, laparotomy, or autopsy wherever indicated. In comparing with CECT scan, FAST had a sensitivity, specificity, and accuracy of 77.27, 100, and 79.16 %, respectively, in the detection of free fluid. When compared with surgical findings, it had a sensitivity, specificity, and accuracy of 94.44, 50, and 90 %, respectively. The sensitivity of FAST was 75 % in determining free fluid in patients who died when compared with autopsy findings. Overall sensitivity, specificity, and accuracy of FAST were 80.43, 75 and 80 %, respectively, for the detection of free fluid in the abdomen. From this study, we can safely conclude that FAST is a rapid, reliable, and feasible investigation in patients with BTA, and it can be performed easily, safely, and quickly in the emergency room with a reasonable sensitivity, specificity, and accuracy. It helps in the initial triage of patients for assessing the need for urgent surgery.
