Sci Rep 2024; 14:2169. [PMID: 38272956 PMCID: PMC10810913 DOI: 10.1038/s41598-024-52657-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Accepted: 01/22/2024] [Indexed: 01/27/2024] Open
Abstract
The Advanced Trauma Life Support (ATLS) approach is generally accepted as the standard of care for the initial management of severely injured patients. While whole body computed tomography (WBCT) is still considered a contraindication in haemodynamically unstable trauma patients, there is a growing amount of data indicating the absence of harm from cross sectional imaging in this patient group. Our study aimed to compare the early mortality of unstable trauma patients undergoing a WBCT during the initial workup with those who did not. Single-center retrospective observational study based on the local trauma registry including 3525 patients with an ISS > 15 from January 2008 to June 2020. We compared the 24-h mortality of injured patients in circulatory shock undergoing WBCT with a control group undergoing standard workup only. Inclusion criteria were the simultaneous presence of a systolic blood pressure < 100 mmHg, lactate > 2.2 mmol/l and base excess < - 2 mmol/l as surrogate markers for circulatory shock. To control for confounding, a propensity score matched analysis with conditional logistic regression for adjustment of residual confounders and a sensitivity analysis using inverse probability weighting (IPW) with and without adjustment were performed. Of the 3525 patients, 161 (4.6%) fulfilled all inclusion criteria. Of these, 132 (82%) underwent WBCT and 29 (18%) standard work-up only. In crude and matched analyses, no difference in early (24 h) mortality was observed (WBCT, 23 (17.4%) and no-WBCT, 8 (27.6%); p = 0.21). After matching and adjustment for main confounders, the odds ratio for the event of death at 24 h in the WBCT group was 0.36 (95% CI 0.07-1.73); p = 0.20. In the present study, WBCT did not increase the risk of death at 24 h among injured patients in shock. This adds to the growing data indicating that WBCT may be offered to trauma patients in circulatory shock without jeopardizing early survival.

Treatment strategy for severe trauma patients requiring aortic occlusion for impending cardiopulmonary arrest in the hybrid emergency room. Acute Med Surg 2024; 11:e928. [PMID: 38293705 PMCID: PMC10825068 DOI: 10.1002/ams2.928] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 01/14/2024] [Accepted: 01/17/2024] [Indexed: 02/01/2024] Open
Abstract
Aim Computed tomography (CT) is useful in trauma care. Severely ill trauma patients may not tolerate whole-body CT even without patient transfer. This study examined clinical flow of severe trauma patients requiring aortic occlusion (AO) such as resuscitative thoracotomy or REBOA in the hybrid emergency room (ER) and investigated patient clinical courses prioritizing CT first versus resuscitation including AO first. Methods This retrospective, single-center observational study included consecutive trauma patients visiting our ER between May 2016 and February 2023. Patients were divided into the CT first group (whole-body CT preceded AO) and AO first group (AO preceded whole-body CT) and into two subgroups: AO after CT (AO/interventions for hemorrhage performed just after CT in the CT first group), and CT after AO (CT or damage control surgery performed after AO in the AO first group). We investigated 28-day survival rates. Results Survival probability by TRISS method was 49% (range: 3.3-94) in the CT first group (n = 6) and 20% (range: 0.7-45) in the AO first group (n = 7). Actual 28-day survival rates were 50% and 57%, respectively. Survival rates of the AO after CT subgroup (CT first group) were 75% (3/4) and 0% (0/2), respectively, and those of the CT after AO subgroup (AO first group) were 25% (1/4) and 100% (3/3), respectively. Conclusion In severe trauma patients with low predicted probability of survival treated in the hybrid ER, survival rates might be better if resuscitation including AO is performed before CT and if damage control surgery is performed first before CT.

Structured approach with primary and secondary survey for major trauma care: an overview of reviews. World J Emerg Surg 2023; 18:2. [PMID: 36600301 PMCID: PMC9814503 DOI: 10.1186/s13017-022-00472-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Accepted: 12/25/2022] [Indexed: 01/05/2023] Open
Abstract
BACKGROUND A structured approach involves systematic management of trauma patients. We aim to conduct an overview of reviews about the clinical efficacy and safety of structured approach (i.e., primary and secondary survey) by guideline checklist compared to non-structured approach (i.e. clinical examination); moreover, routine screening whole-body computer tomography (WBCT) was compared to non-routine WBCT in patients with suspected major trauma. METHODS We systematically searched MEDLINE (PubMed), EMBASE and Cochrane Database of Systematic Reviews up to 3 May 2022. Systematic reviews (SRs) that investigated the use of a structured approach compared to a non-structured approach were eligible. Two authors independently extracted data, managed the overlapping of primary studies belonging to the included SRs and calculated the corrected covered area (CCA). The certainty of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. RESULTS We included nine SRs investigating two comparisons in stable trauma patients: structured approach vs non-structured approach (n = 1) and routine WBCT vs non-routine WBCT (n = 8). The overlap of included primary studies was generally high across outcomes (CCA ranged between 20.85 and 42.86%) with some discrepancies in the directions of effects across reviews. The application of a structured approach by checklist may improve adherence to guidelines (e.g. Advanced Trauma Life Support) during resuscitation and might lead to a reduction in mortality among severely injured patients as compared to clinical examination (Adjusted OR 0.51; 95% CI 0.30-0.89; p = 0.018; low certainty of evidence). The use of routine WBCT seems to offer little to no effects in reducing mortality and time spent in emergency room or department, whereas non-routine WBCT seems to offer little to no effects in reducing radiation dose, intensive care unit length of stay (LOS) and hospital LOS (low-to-moderate certainty of evidence). CONCLUSIONS The application of structured approach by checklist during trauma resuscitation may improve patient- and process-related outcomes. Including non-routine WBCT seems to offer the best trade-offs between benefits and harm. Clinicians should consider these findings in the light of their clinical context, the volume of patients in their facilities, the need for time management, and costs.

Abstract
A novel trauma workflow system called the hybrid emergency room (Hybrid ER) that combines a sliding computed tomography (CT) scanning system with interventional radiology features was first installed in Osaka General Medical Center in 2011. The Hybrid ER enables CT diagnosis and emergency therapeutic interventions without transferring the patient to another examination room. In this article, the history of CT in trauma care, the world's first installation of the Hybrid ER, clinical experiences, and evidence for the Hybrid ER in trauma workflow and nontrauma fields are summarized, and the future and innovation of the Hybrid ER are reviewed.

Simultaneous treatment of trauma patients in a dual room trauma suite with integrated movable sliding gantry CT system: an observational study. Sci Rep 2022; 12:16065. [PMID: 36168030 PMCID: PMC9515087 DOI: 10.1038/s41598-022-20491-2] [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: 03/23/2022] [Accepted: 09/14/2022] [Indexed: 11/24/2022] Open
Abstract
The trauma center of the University Hospital Wuerzburg has developed an advanced trauma pathway based on a dual-room trauma suite with an integrated movable sliding gantry CT-system. This enables simultaneous CT-diagnostics and treatment of two trauma patients. The focus of this study was to investigate the quality of the concept based on defined outcome criteria in this specific setting (time from arrival to initiation of CT scan: tCT; time from arrival to initiation of emergency surgery: tES). We analyzed all trauma patients admitted to the hospital’s trauma suite from 1st May 2019 through 29th April 2020. Two subgroups were defined: trauma patients, who were treated without a second trauma patient present (group 1) and patients, who were treated simultaneously with another trauma patient (group 2). Simultaneous treatment was defined as parallel arrival within a period of 20 min. Of 423 included trauma patients, 46 patients (10.9%) were treated simultaneously. Car accidents were the predominant trauma mechanism in this group (19.6% vs. 47.8%, p < 0.05). Prehospital life-saving procedures were performed with comparable frequency in both groups (intubation 43.5% vs. 39%, p = 0.572); pleural drainage 3.2% vs. 2.2%, p = 0.708; cardiopulmonary resuscitation 5% vs. 2.2%, p = 0.387). At hospital admission, patients in group 2 suffered significantly more pain (E-problem according to Advanced Trauma Life Support principles©; 29.2% vs. 45.7%, p < 0.05). There were no significant differences in the clinical treatment (emergency procedures, vasopressor and coagulant therapy, and transfusion of red blood cells). tCT was 6 (4–10) minutes (median and IQR) in group 1 and 8 (5–15.5) minutes in group 2 (p = 0.280). tES was 90 (78–106) minutes in group 1 and 99 (97–108) minutes in group 2 (p = 0.081). The simultaneous treatment of two trauma patients in a dual-room trauma suite with an integrated movable sliding gantry CT-system requires a medical, organizational, and technical concept adapted to this special setting. Despite the oftentimes serious and life-threatening injuries, optimal diagnostic and therapeutic procedures can be guaranteed for two simultaneous trauma patients at an individual medical level in consistent quality.

A Comparative Study of Intravital CT and Autopsy Findings in Fatal Traumatic Injuries. Healthcare (Basel) 2022; 10:healthcare10081465.

Abstract
Objectives: Traumatic injuries are one of the severe health problems of our time. In the 21st Century, approximately 4.5 million people worldwide die each year due to trauma. Computed tomography (CT) is widely used to diagnose injuries and offers information on the specific location and extent of organ and tissue damage. In cases of severe trauma, whole-body CT is increasingly used as a standard diagnostic technique. An autopsy is the final diagnostic examination and is still considered the gold standard in diagnostic methods in medicine. The aim of the study was to assess the reliability and accuracy of CT scan results, as well as limits in detecting trauma for forensic purposes. It aims to compare traumatic findings in the antemortem CT results to those observed at autopsy. Materials and Methods: We conducted a retrospective–prospective study involving 510 deaths due to trauma. We compared selected traumatic changes in the antemortem CT scan results with the autopsy findings. We obtained data with a detailed analysis of autopsy protocols, photographic documentation from the autopsies, and the interpretation of CT scans from medical documentation. In cases of discrepancies in the findings, we borrowed CT scans, which were repeatedly reviewed by clinical radiologists. Results: By comparing the findings of selected injuries detected by antemortem CT and autopsy, we found a correlation of findings in 75.3% and a discrepancy of findings in 24.7% in a set of 510 cases. After repeated targeted assessment of CT images by clinical radiologists in cases of discrepancies in the findings, which were detected by autopsy and undescribed by CT, the discrepancy decreased to 17%. Conclusions: The results of the study are comparable with data from many studies and professional publications. They show that CT compared to autopsy is a good method for diagnosing gunshot wounds to the head and bone fractures, with a limited diagnosis of cranial base fractures, while an autopsy is better for detecting minor injuries to organs and soft tissues.

Abstract
INTRODUCTION Computerized tomography (CT) scans are the mainstay of diagnostic imaging in blunt trauma. Particularly in pediatric trauma, utilization of CT scans has increased exponentially in recent years. Concerns regarding radiation exposure to this vulnerable population have resulted in increased scrutiny of practice. What is not known is if liberal imaging practices decrease length of stay by eliminating the need for clinical observation, and the impact of false-positive rates from liberal use of CT scanning on clinical outcomes. METHODS Medical records from a nonaccredited pediatric trauma center with a practice of liberal imaging were reviewed over a 2-year period. Total CT scans obtained were recorded, in addition to length of stay, age, and Injury Severity Score (ISS). Rates of clinically significant imaging findings were recorded, as were false positive findings and complications of imaging. RESULTS Out of 735 children, 58% underwent CT scanning, and if scanned, received an average of 2.4 studies. Clinically significant findings were documented in 20% of head CTs, 2% of cervical spine CTs, 3.5% of chest CTs, 24% of facial CTs, and 14.7% of abdominal CTs. False-positive findings were found in 1.5% of head CTs, 1.2% of cervical spine CTs, 2.4% of chest CTs, and 2.5% of abdominal CTs. Liberal CT scanning was not associated with decreased length of stay. In contrast, obtaining CT scans on more than 4 body regions was independently predictive of longer length of stay, independent of ISS. CONCLUSIONS False-positive rates of CT scans for trauma were low in this cohort. However, when scanning the cervical spine or the chest, for every 2 clinically significant findings obtained, there was at least one false positive result, calling into question the practice of liberal imaging of these regions. Liberal utilization of CT scan did not allow for more rapid discharge home, and for more than 4 CTs was independently associated with longer hospital stay.

Abstract
Background A hybrid emergency room (ER) is defined as an emergency unit with four functions—performing resuscitation, computed tomography (CT), surgery, and angiography. However, the safety and efficacy of performing CT in a hybrid ER are unclear in primary surveys. Therefore, this study aimed to evaluate the safety and clinical effects of hybrid ERs. Methods This retrospective observational study used data from the Shimane University Hospital Trauma Database from January 2016 to February 2019. Hospitalized patients with severe trauma and an injury severity score of ≥ 16 were divided into the non-hybrid ER group (n = 134) and the hybrid ER group (n = 145). The time from arrival to CT and interventions and the number of in-hospital survivors, preventable trauma deaths (PTD), and unexpected survivors (US) were assessed in both groups. Further, the amount of blood transfused was compared between the groups using propensity score matching. Results The time from arrival to CT and interventions was significantly reduced in the hybrid ER group compared to that in the non-hybrid ER group (25 vs. 6 min; p < 0.0001 and 101 vs. 41 min; p = 0.0007, respectively). There was no significant difference in the rate of in-hospital survivors (96.9% vs. 96.3%; p = 0.770), PTD (0% vs. 0%), and US (9.0 vs. 6.2%; p = 0.497) between the groups. The amount of blood transfused was significantly lower in the hybrid ER group than in the non-hybrid ER group (whole blood 14 vs. 8, p = 0.004; red blood cell 6 vs. 2, p = 0.012; fresh frozen plasma 9 vs. 6, p = 0.021). This difference was maintained after propensity score matching (whole blood 28 [10–54] vs. 6 [4–16.5], p = 0.015; RBC 8 [2.75–26.5] vs. 2 [0–8.5], p = 0.020, 18 [5.5–27] vs. 6 [3.5–7.5], p = 0.057). Conclusions The study results suggest that trauma treatment in a hybrid ER is as safe as conventional treatment performed in a non-hybrid ER. Further, hybrid ERs, which can reduce the time for trauma surveys and treatment, do not require patient transfer and can reduce the amount of blood transfused during resuscitation.

Abstract
Background A novel trauma workflow system called the hybrid emergency room (Hybrid ER), which combines a sliding CT scanner system with interventional radiology features (IVR-CT), was initially instituted in our emergency department in 2011. Use of the Hybrid ER enables CT diagnosis and emergency therapeutic interventions without transferring the patient to another room. We describe an illustrative case of severe multiple blunt trauma that included injuries to the brain and torso to highlight the ability to perform multiple procedures in the Hybrid ER. Case presentation A 46-year-old man sustained multiple injuries after falling from height. An early CT scan performed in the Hybrid ER revealed grade IIIa thoracic aortic injury, left lung contusion, and right subdural haematoma and subarachnoid haemorrhage. Without relocating the patient, all definitive procedures, including trepanation, total pneumonectomy, and thoracic endovascular aneurysm repair were performed in the Hybrid ER. At 5.72 h after definitive surgery was begun, the patient was transferred to the intensive care unit. Conclusions The Hybrid ER has the potential to facilitate the performance of multiple definitive procedures in combination to treat severe multiple blunt trauma including injuries to the brain and torso. Emergency departments with more than one resuscitation room would benefit from a Hybrid ER to treat complex emergency cases.

Diagnostic accuracy, yield, and comparative effectiveness of whole-body computed tomography in blunt trauma: A protocol for systematic review and meta-analysis. Medicine (Baltimore) 2021; 100:e24205. [PMID: 33466198 PMCID: PMC7808510 DOI: 10.1097/md.0000000000024205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Accepted: 12/15/2020] [Indexed: 01/05/2023] Open
Abstract
OBJECTIVES Controversies emerge over routine performances of whole-body computed tomography (WBCT) in patients with blunt polytrauma. The existing randomized and non-randomized evidence is inconclusive, and during observations of non-trauma, incidental findings, detected by WBCT, have left uncertainty regarding their consequences and optimal management. Additionally, previous meta-analyses have failed to address the limitations of primary studies and issues associated with incidental findings. Therefore, we planned a new systematic review to address these points. METHODS We will search the PubMed, EMBASE, and Cochrane Central databases from inception to December 31, 2020, with no language restriction and perform full-text evaluation of potentially relevant articles. We will include prospective and retrospective studies with a single-gate design that assessed diagnostic accuracy and/or yield of WBCT to detect traumatic injuries, and studies that assessed incidental findings detected by WBCT. Additionally, we will include randomized controlled trials and non-randomized comparative studies that assessed the effectiveness of WBCT against conventional care, including selective computed tomography (CT). Studies of patients of all ages with blunt traumatic injuries, assessed at an emergency department, will be included. Two reviewers will extract data and rate the study validity via standard quality assessment tools. The primary outcome of interest will be reduction in mortality. Our secondary outcomes will include diagnostic accuracy and yield, detection of incidental findings and clinical outcomes associated with these detections, and improvement in other non-mortality clinical outcomes. We will qualitatively assess study, patient, and intervention characteristics and clinical outcomes. If appropriate, we will perform random-effects model meta-analyses to obtain summary estimates. Finally, we will assess the certainty of evidence by the grading the quality of evidence and strength of recommendations. ETHICS AND DISSEMINATION Ethics approval is not applicable, as this is a secondary analysis of publicly available data. The review results will be submitted for publication in peer-reviewed journals.

Abstract
Trauma is a complex pathology that requires an experienced multidisciplinary team with an inherent quick decision-making capacity, given that a few minutes could represent a matter of life or death. These management decisions not only need to be quick but also accurate to be able to prioritize and to efficiently control the injuries that may be causing impending hemodynamic collapse. In essence, this is the cornerstone of the concept of damage control trauma care. With current technological advances, physicians have at their disposition multiple diagnostic imaging tools that can aid in this prompt decision-making algorithm. This manuscript aims to perform a literature review on this subject and to share the experience on the use of whole body computed tomography as a potentially safe, effective and efficient diagnostic tool in cases of severely injured trauma patients regardless of their hemodynamic status. Our general recommendation is that, when feasible, perform a whole body computed tomography without interrupting ongoing hemostatic resuscitation in cases of severely injured trauma patients with or without signs of hemodynamic instability. The use of this technology will aid in the decision-making of the best surgical approach for these patients without incurring any delay in definitive management and/or increasing significantly their radiation exposure.

Abstract
PURPOSE The superior diagnostic accuracy of CT makes it an attractive tool for initial trauma imaging. This meta-analysis aimed to assess the evidence regarding the value of whole-body CT (WBCT) as part of the primary survey, in comparison to conventional radiological procedures. METHODS A comprehensive systematic search of the literature was conducted using keywords applied in Scopus, Cochrane and PubMed databases. Articles were eligible if they contained original data comparing the use of WBCT in the primary survey, with conventional radiological procedures. Outcomes included overall and 24 -h mortality, emergency department (ED) time, intensive care unit (ICU) and hospital length of stay (LOS), and multiple organ dysfunction syndrome/failure (MODS/MOF) incidence. Radiation dose, mechanical ventilation duration and cost were evaluated qualitatively. Analysis was performed with Covidence, MedCalc Version 19.1.3. and Meta-Essentials. RESULTS Fourteen studies were included. Statistical pooling demonstrated comparable rates between conventional procedures and WBCT (OR = 0.854, CI = 0.715-1.021, p = 0.083) in 63,529 patients across 11 studies. A significant finding favouring WBCT was discovered for ED time (SMD = -0.709, CI -1.198 to -0.220, p = 0.004). Patients experienced similar 24 -h mortality rates (p = 0.450), MODS/MOF incidence (p = 0.274), and hospital (p = 0.541) and ICU LOS (p = 0.457). WBCT is associated with increased radiation dose and mechanical ventilation duration. CONCLUSION This review demonstrates that WBCT markedly reduces time spent in ED. No significant differences in mortality rate are suggested. WBCT currently entails greater radiation dose and mechanical ventilation time. Further research is necessitated to address limitations of predominately retrospective observational data available.

Abstract
Purpose The trauma centre of the Wuerzburg University Hospital has integrated a pioneering dual-room twin-CT scanner in a multiple trauma pathway. For concurrent treatment of two trauma patients, two carbon CT examination and intervention tables are positioned head to head with one sliding CT-Gantry in the middle. The focus of this study is the process of trauma care with the time to CT (tCT) and the time to operation (tOR) as quality indicator. Methods All patients with suspected multiple trauma, who required emergency surgery and who were initially diagnosed by the CT trauma protocol between 05/2018 and 12/2018 were included. Data relating to time spans (tCT and tOR), severity of injury and outcome was obtained. Results 110 of the 589 screened trauma patients had surgery immediately after finishing primary assessment in the ER. The ISS was 17 (9–34) (median and interquartile range, IQR). tCT was 15 (11–19) minutes (median and IQR) and tOR was 96.5 (75–119) minutes (median and IQR). In the first 30 days, seven patients died (6.4%) including two within the first 24 h (2%). There were two ICU days (1–6) (median and IQR) and one (0–1) (median and IQR) ventilator day. Conclusion The twin-CT technology is a fascinating tool to organize high-quality trauma care for two multiple trauma patients simultaneously.

Abstract
Purpose: The objective of this study was to evaluate the implementation of a new single-pass whole-body computed tomography Protocol in the management of patients with severe trauma. Methods: This was a descriptive evaluation of polytrauma patients who underwent whole-body computed tomography. Patients were divided into three groups: 1. Blunt trauma hemodynamically stable 2. Blunt trauma hemodynamically unstable and 3. Penetrating trauma. Demographics, whole-body computed tomography parameters and outcome variables were evaluated. Results: Were included 263 patients. Median injury severity score was 22 (IQR: 16-22). Time between arrival to the emergency department and completing the whole-body computed tomography was under 30 minutes in most patients [Group 1: 28 minutes (IQR: 14-55), Group 2: 29 minutes (IQR: 16-57), and Group 3: 31 minutes (IQR: 13-50; p= 0.96)]. 172 patients (65.4%) underwent non-operative management. The calculated and the real survival rates did not vary among the groups either [Group 1: TRISS 86.4% vs. real survival rate 85% (p= 0.69); Group 2: TRISS 69% vs. real survival rate 74% (p= 0.25); Group 3: TRISS 93% vs. real survival rate 87% (p= 0.07)]. Conclusion: This new single-pass whole-body computed tomography protocol was safe, effective and efficient to decide whether the patient with severe trauma requires a surgical intervention independently of the mechanism of injury or the hemodynamic stability of the patient. Its use could also potentially reduce the rate of unnecessary surgical interventions of patients with severe trauma including those with penetrating trauma.

Abstract
Introducción. La tomografía corporal (TC) total en la evaluación de pacientes con trauma grave, puede ser una herramienta eficaz y segura para decidir entre un tratamiento quirúrgico y uno no quirúrgico, pero aún no son claras las implicaciones diagnósticas y los riesgos asociados con esta técnica.
Métodos. Se incluyeron pacientes mayores de 15 años con trauma grave que fueron sometidos a TC total. Se evaluaron la seguridad, la efectividad y la eficiencia por medio de los parámetros de incidencia de nefropatía inducida por los medios de contraste, dosis total de radiación por paciente, proporción de casos en los que la TC total cambió el manejo, y el retraso en el diagnóstico.
Resultados. Se incluyeron 263 pacientes, 83 % sufrieron trauma cerrado y 17 % sufrieron trauma penetrante. La gravedad de la lesión fue mayor en estos últimos y, sin embargo, el trauma cerrado con inestabilidad hemodinámica se presentó con mayores grados de choque. El 65 % de los pacientes recibió tratamiento selectivo no operatorio. Entre los subgrupos, no hubo diferencias significativas en el tiempo entre el ingreso a la sala de urgencias y la toma de la TC total (p=0,96) y, en la mayoría de los casos, el tiempo entre la práctica de la TC total y el diagnóstico de presencia o ausencia de heridas fue menor de 25 minutos. La mediana de radiación total estuvo por debajo de 20 mSv en todos los grupos. No hubo diferencias significativas en la mortalidad (p=0,17).
Conclusión. La TC total es una herramienta segura y eficiente para decidir entre un tratamiento quirúrgico y uno no quirúrgico en los casos de trauma grave, independientemente del mecanismo de la lesión o la estabilidad hemodinámica al ingreso.

Abstract
Objectives Initial trauma care could potentially be improved when conventional imaging and selective CT scanning is omitted and replaced by immediate total-body CT (iTBCT) scanning. Because of the potentially increased radiation exposure by this diagnostic approach, proper selection of the severely injured patients is mandatory. Methods In the REACT-2 trial, severe trauma patients were randomized to iTBCT or conventional imaging and selective CT based on predefined criteria regarding compromised vital parameters, clinical suspicion of severe injuries, or high-risk trauma mechanisms in five trauma centers. By logistic regression analysis with backward selection on the 15 study inclusion criteria, a revised set of criteria was derived and subsequently tested for prediction of severe injury and shifts in radiation exposure. Results In total, 1083 patients were enrolled with median ISS of 20 (IQR 9–29) and median GCS of 13 (IQR 3–15). Backward logistic regression resulted in a revised set consisting of nine original and one adjusted criteria. Positive predictive value improved from 76% (95% CI 74–79%) to 82% (95% CI 80–85%). Sensitivity decreased by 9% (95% CI 7–11%). The area under the receiver operating characteristics curve remained equal and was 0.80 (95% CI 0.77–0.83), original set 0.80 (95% CI 0.77–0.83). The revised set retains 8.78 mSv (95% CI 6.01–11.56) for 36% of the non-severely injured patients. Conclusions Selection criteria for iTBCT can be reduced from 15 to 10 clinically criteria. This improves the positive predictive value for severe injury and reduces radiation exposure for less severely injured patients. Key Points • Selection criteria for iTBCT can be reduced to 10 clinically useful criteria. • This reduces radiation exposure in 36% of less severely injured patients. • Overall discriminative capacity for selection of severely injured patients remained equal.

Clinical guided computer tomography decisions are advocated in potentially severely injured trauma patients: a one-year audit in a level 1 trauma Centre with long pre-hospital times. Scand J Trauma Resusc Emerg Med 2020; 28:2. [PMID: 31924242 PMCID: PMC6954603 DOI: 10.1186/s13049-019-0692-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2019] [Accepted: 11/26/2019] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND The International Commission on Radiological Protection's (ICRP) justification principles state that an examination is justified if the potential benefit outweighs the risk for radiation harm. Computer tomography (CT) contributes 50% of the radiation dose from medical imaging, and in trauma patients, the use of standardized whole body CT (SWBCT) increases. Guidelines are lacking, and reviews conclude conflictingly regarding the benefit. We aimed to study the degree of adherence to ICRP's level three justification, the individual dose limitation principle, in our institution. METHODS This is a retrospective clinical audit. We included all 144 patients admitted with trauma team activation to our regional Level 1 trauma centre in 2015. Injuries were categorized according to the Abbreviated Injury Scale (AIS) codes. Time variables, vital parameters and interventions were registered. We categorized patients into trauma admission SWBCT, selective CT or no CT examination strategy groups. We used descriptive statistics and regression analysis of predictors for CT examination strategy. RESULTS The 144 patients (114 (79.2%) males) had a median age of 31 (range 0-91) years. 105 (72.9%) had at least one AIS ≥ 2 injury, 26 (18.1%) in more than two body regions. During trauma admission, at least one vital parameter was abnormal in 46 (32.4%) patients, and 73 (50.7%) underwent SWBCT, 43 (29.9%) selective CT and 28 (19.4%) no CT examination. No or only minor injuries were identified in 17 (23.3%) in the SWBCT group. Two (4.6%) in the selective group were examined with a complement CT, with no new injuries identified. A significantly (p < 0.001) lower proportion of children (61.5%) than adults (89.8%) underwent CT examination despite similar injury grades and use of interventions. In adjusted regression analysis, patients with a high-energy trauma mechanism had significantly (p = 0.028) increased odds (odds ratio = 4.390, 95% confidence interval 1.174-16.413) for undergoing a SWBCT. CONCLUSION The high proportion of patients with no or only minor injuries detected in the SWBCT group and the significantly lower use of CT among children, indicate that use of a selective CT examination strategy in a higher proportion of our patients would have approximated the ICRP's justification level three, the individual dose limitation principle, better.

Abstract
Objective Several scoring systems have been developed to identify patients who require massive transfusion (MT) after major trauma to improve survival. The primary goal of this study was to investigate the usefulness of enhanced computed tomography attenuation values (CTAVs) of major vessels to determine the need for MT in patients with major blunt trauma. Methods This single-center retrospective cohort study evaluated patients aged 16 years or older who underwent contrast-enhanced computed tomography scan of the torso after major blunt trauma. The CTAVs of six major vessel points in both the arterial and portal venous phases at initial computed tomography examination were assessed and compared between the MT and the no MT group. The capability of enhanced CTAVs to predict the necessity for MT was estimated based on the area under the receiver operating characteristic curve. Results Of the 254 eligible patients, 36 (14%) were in the MT group. Patients in the MT group had significantly higher CTAVs at all sites except the inferior vena cava in both the arterial and portal venous phases than that in the no MT group. The descending aorta in the arterial phase had the highest accuracy for predicting MT, with an AUROC of 0.901 (95% confidence interval, 0.855 to 0.947; P<0.001). Conclusion Initial elevation of enhanced CTAV of the aorta is a predictor for the need for MT. A higher CTAV of the aorta should alert the trauma surgeon or emergency physician to activate their MT protocol.

Abstract
OBJECTIVE To develop French guidelines on the management of patients with severe abdominal trauma. DESIGN A consensus committee of 20 experts from the French Society of Anaesthesiology and Critical Care Medicine (Société française d'anesthésie et de réanimation, SFAR), the French Society of Emergency Medicine (Société française de médecine d'urgence, SFMU), the French Society of Urology (Société française d'urologie, SFU) and from the French Association of Surgery (Association française de chirurgie, AFC), the Val-de-Grâce School (École du Val-De-Grâce, EVG) and the Federation for Interventional Radiology (Fédération de radiologie interventionnelle, FRI-SFR) was convened. Declaration of all conflicts of interest (COI) policy by all participants was mandatory throughout the development of the guidelines. The entire guideline process was conducted independently of any industry funding. The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system for assessment of the available level of evidence with particular emphasis to avoid formulating strong recommendations in the absence of high level. Some recommendations were left ungraded. METHODS The guidelines are divided in diagnostic and, therapeutic strategy and early surveillance. All questions were formulated according to Population, Intervention, Comparison, and Outcomes (PICO) format. The panel focused on three questions for diagnostic strategy: (1) What is the diagnostic performance of clinical signs to suggest abdominal injury in trauma patients? (2) Suspecting abdominal trauma, what is the diagnostic performance of prehospital FAST (Focused Abdominal Sonography for Trauma) to rule in abdominal injury and guide the prehospital triage of the patient? and (3) When suspecting abdominal trauma, does carrying out a contrast enhanced thoraco-abdominal CT scan allow identification of abdominal injuries and reduction of mortality? Four questions dealt with therapeutic strategy: (1) After severe abdominal trauma, does immediate laparotomy reduce morbidity and mortality? (2) Does a "damage control surgery" strategy decrease morbidity and mortality in patients with a severe abdominal trauma? (3) Does a laparoscopic approach in patients with abdominal trauma decrease mortality or morbidity? and (4) Does non-operative management of patients with abdominal trauma without bleeding reduce mortality and morbidity? Finally, one question was formulated regarding the early monitoring of these patients: In case of severe abdominal trauma, which kind of initial monitoring does allow to reduce the morbi-mortality? The analysis of the literature and the recommendations were conducted following the GRADE® methodology. RESULTS The SFAR/SFMU Guideline panel provided 15 statements on early management of severe abdominal trauma. After three rounds of discussion and various amendments, a strong agreement was reached for 100% of recommendations. Of these recommendations, five have a high level of evidence (Grade 1±), six have a low level of evidence (Grade 2±) and four are expert judgments. Finally, no recommendation was provided for one question. CONCLUSIONS Substantial agreement exists among experts regarding many strong recommendations for the best early management of severe abdominal trauma.

Abstract
Background Immediate total-body CT (iTBCT) is often used for screening of potential severely injured patients. Patients requiring emergency bleeding control interventions benefit from fast and optimal trauma screening. The aim of this study was to assess whether an initial trauma assessment with iTBCT is associated with lower mortality in patients requiring emergency bleeding control interventions. Methods In the REACT-2 trial, patients who sustained major trauma were randomized for iTBCT or for conventional imaging and selective CT scanning (standard workup; STWU) in five trauma centers. Patients who underwent emergency bleeding control interventions following their initial trauma assessment with iTBCT were compared for mortality and clinically relevant time intervals to patients that underwent the initial trauma assessment with the STWU. Results In the REACT-2 trial, 1083 patients were enrolled of which 172 (15.9%) underwent emergency bleeding control interventions following their initial trauma assessment. Within these 172 patients, 85 (49.4%) underwent iTBCT as primary diagnostic modality during the initial trauma assessment. In trauma patients requiring emergency bleeding control interventions, in-hospital mortality was 12.9% (95% CI 7.2–21.9%) in the iTBCT group compared to 24.1% (95% CI 16.3–34.2%) in the STWU group (p = 0.059). Time to bleeding control intervention was not reduced; 82 min (IQR 5–121) versus 98 min (IQR 62–147), p = 0.108. Conclusions Reduction in mortality in trauma patients requiring emergency bleeding control interventions by iTBCT could not be demonstrated in this study. However, a potentially clinically relevant absolute risk reduction of 11.2% (95% CI − 0.3 to 22.7%) in comparison with STWU was observed. Trial registration ClinicalTrials.gov: NCT01523626.

Abstract
BACKGROUND Whole-body computed tomography (WBCT) is increasingly being incorporated into the initial management of blunt trauma patients. Several observational studies have suggested that, compared to selective CT, WBCT is associated with lower mortality. In contrast, a randomized controlled trial found no significant difference in survival between patients undergoing WBCT compared to selective CT. Our objective was to confirm the association between WBCT and in-hospital mortality among adult severe blunt trauma patients. METHODS This was a retrospective cohort study based on Japan Trauma Data Bank 2004-2015 registry data. The study population comprised adult severe blunt trauma patients with at least one abnormal vital sign: systolic blood pressure ≤100 mmHg, heart rate ≥120, respiratory rate ≥30 or ≤10, or Glasgow Coma Score ≤13. The primary outcome was in-hospital mortality. To adjust for both measured and unmeasured confounders, we performed instrumental variable (IV) analysis to compare the in-hospital mortality of patients undergoing WBCT with those undergoing selective CT. RESULTS Of 40,435 patients who were eligible for this study, 19,766 (48.9%) patients underwent WBCT. The proportion of patients undergoing WBCT significantly increased during the study period, from 10.7% in 2004 to 59.6% in 2015. Primary IV analysis showed a significant association between WBCT and lower in-hospital mortality (odds ratio 0.84, 95% confidence interval 0.72-0.98). CONCLUSIONS WBCT can be beneficial in patients with blunt trauma which has compromised vital signs. These findings from a nationwide study suggest that physicians should consider WBCT for blunt trauma patients when warranted by vital signs.

Abstract
Many authors adopt the Selected Computed Tomography (SCT) approach of the Advanced Trauma Life Support (ATLS) for the management of multiple trauma patients. In the SCT approach, the initial physical examination is followed by conventional radiography (cervical X-ray, chest X-ray, pelvic X-ray and Focused Abdominal Sonography in Trauma (FAST)), and the computed tomography (CT) of the specific body regions if indicated. An alternative to this traditional approach is the Whole-body Computed Tomography (WBCT) protocol, which became widespread all over the world in the last two decades to minimize the rate of missed injuries and decrease the mortality rate. According to the literature, the WBCT approach is superior to the traditional SCT approach in the time of imaging, diagnostic accuracy, and mortality rates. Conversely, WBCT increases the cancer risk due to additional irradiation. Therefore, it is recommended that the WBCT protocol should be reserved for only severe multi-trauma patients. However, further studies to define severe patients, and clinical decision criteria for WBCT are needed.

Abstract
PURPOSE OF REVIEW To provide an update on the relevant and recent studies on whole-body computed tomography (WBCT) imaging of severely injured patients. RECENT FINDINGS The advantages of WBCT in time saving, diagnostic accuracy and even in survival have been proven in numerous studies. WBCT can also be beneficial in haemodynamically unstable major trauma patients. The CT scanner should be located close to the emergency department or even in the trauma room. The issue of radiation is still quite important, however, iterative as well as split-bolus protocols can nowadays reduce radiation significantly. The question: which trauma patient should receive WBCT and which not is not yet solved sufficiently. Postmortem WBCT has a promising potential to promptly define the definitive cause of death of trauma victims comparably to traditional autopsy. SUMMARY On account of the recent advances, whole-body CT has become a crucial part of the initial in-hospital assessment of severely injured patients. It is recommended as the standard radiological tool for the emergency diagnostic work-up in major trauma patients.

Abstract
The hybrid emergency room (hybrid ER) system was first established in 2011 in Japan. It is defined as an integrated system including an ER, emergency computed tomography (CT) and interventional radiology (IVR) rooms, and operating rooms. Severe trauma patients can undergo emergency CT examinations and therapies (surgeries) without being transferred. The hybrid ER system is attracting attention because trauma resuscitation using this system has been reported to potentially improve the mortality rate in severe trauma patients. In August 2017, we established a new table-rotated-type hybrid ER to facilitate surgical functions. Herein, we introduce a new table-rotated-type hybrid ER consisting of an IVR–CT–operating room system and discuss its efficiency and feasibility for trauma resuscitation, including surgery and IVR. This system includes four new concepts: (1) to secure a wide working space during trauma resuscitation by reconsidering the arrangement of the C-arm, (2) ensure an air-conditioned operating room in the hybrid ER, (3) adopt an operating table but not interventional radiology table, and (4) prepare a trauma bay with three additional beds for multiple victims. This hybrid ER system also adopted the rotated-type table to secure a wide working space during the resuscitation phase. The C-arm was located away from the patients and placed on the wall opposite to the CT gantry, in contrast to that in previous systems. If patients needed an emergency IVR, the table was just rotated, and the IVR could be conducted immediately. This improvement can secure a wide working space in the hybrid ER. Moreover, the patient table was also a surgical operating table, and the hybrid ER system had an air-conditioned operating room (class 10,000). In the anticipation of many trauma patients being transported to the ER, a new trauma bay with three additional beds next to the hybrid ER was established, which also had an air-conditioned operating room. This new rotated-type hybrid ER system facilitates efficient surgical functions during trauma resuscitation and can secure a wide working space for the medical team to immediately perform resuscitative procedures and IVRs without delay.

Abstract
Performing accurate diagnosis using computed tomography (CT) in emergency medicine may reduce mortality rates in various diseases. In this observational, correlational and cross-sectional study, we conducted multiple regression analyses to investigate the relationship between CT utilization rates and mortality. In addition, we estimated the annual net profits from CT to show the profitability of introducing a CT system in each Japanese prefecture. We conducted a multiple regression analysis to investigate correlations between CT utilization rates and mortality from each disease adjusted for the population density, number of doctors, as well as transportation time to the medical institution. The results of multiple regression analysis showed that traffic accident mortality was related to CT utilization rate and population density. Extrinsic death such as mortality due to falling, drowning and asphyxia was related to CT utilization, indicating that CT in emergency medicine reduced mortality. Moreover, the annual net profit from multi-slice CT (MSCT) was estimated as positive. Our study clearly demonstrates that CT utilization rates relate to a reduction in mortality from accidents, indicating that screening patients with CT in the emergency room has a beneficial effect and reduces mortality. Therefore, CT equipment has a beneficial effect in both emergency medicine and hospital management.

Abstract
Purpose To determine radiologic and clinical markers predictive of missed injuries at early whole-body CT image interpretation. Materials and Methods For this retrospective study, 2354 consecutive whole-body CT examinations were performed in patients with multiple traumas from 26 hospitals interpreted at a teleradiology center study during on-call period from February 2011 to September 2016. All whole-body CT images were interpreted by the on-call radiologist and reviewed within 12-48 hours by another radiologist to detect missed injury as the standard of reference. The first and review reports of all examinations were retrospectively reviewed. Univariable and multivariable logistic regression with a stepwise selection method were performed to identify clinical and radiologic predictors of missed injury. Results This study included 639 women (27.1%) and 1715 men (72.8%). The median age of men, women, and the entire population was 34 years (age range, 1-96 years). On a per-scan basis, there were 304 (12.9%) missed injuries and 59 (2.5%) were clinically significant. On a per-injury basis, the missed injury rate was 530 of 5979 (8.8%). More than two injured body parts (odds ratio, 1.4 [95% confidence interval: 1.1, 1.8]; P = .01), patient age older than 30 years (odds ratio, 2.8 [95% confidence interval: 2.1, 3.8]; P < .001), and an initial clinical severity class of 1 (odds ratio, 1.9 [95% confidence interval: 1.3, 2.8]; P < .001) were independent predictive factors of missed injury. Conclusion Multiple traumas with more than two injured body parts, age older than 30 years, or an initial clinical severity class of 1 were associated with missed injury at whole-body CT. © RSNA, 2018 Online supplemental material is available for this article.

Abstract
According to guidelines from the Eastern Association for the Surgery of Trauma, computed tomography (CT) with intravenous contrast is strongly recommended to diagnose clinically significant blunt traumatic aortic injury (BTAI). However, it remains unclear whether the timing of CT scanning is associated with the prognosis of BTAI patients.We extracted data on emergency patients who suffered a BTAI in the chest and/or the abdomen from 2004 to 2015 from the Japanese Trauma Data Bank, a nationwide trauma registry. The primary outcome was death in the emergency department (ED) and secondary outcome was discharge to death. In addition, we assessed the relationship between death in the ED and the timing of CT scanning by shock status in subgroup analysis. We divided these patients into the tertile groups of early (≤26 minutes), middle (27-40 minutes), and late (≥41 minutes) phases based on the time interval from hospital arrival to start of first CT scanning, and assessed death of BTAI patients in the ED by CT scanning time with the use of a multivariable logistic regression model.In total, 421 patients who suffered BTAI in the chest and/or the abdomen were eligible for our analysis. The proportion of patients dying at hospital admission was 7.7% (11/142) in the early group, 11.1% (15/135) in the middle group, and 17.6% (25/144) in the late group. In a multivariable logistic regression adjusted for confounding factors, the adjusted odds ratio (AOR) of death in the ED was 1.833 (95% confidence interval [CI]: 0.601-5.590, P = .287) in the middle group and 2.832 (95% CI: 1.007-7.960, P = .048) in the late group compared with the early group. Compared with the early group, the late group tended to have a higher rate of discharge to death (AOR: 1.438, 95% CI: 0.735-2.813). In the patients with shock, the AOR was 3.292 (95% CI: 0.495-21.902) in the middle group and 6.039 (95% CI: 0.990-36.837) in the late group compared with the early group.This study revealed that a longer time interval from hospital arrival to CT scanning was associated with higher mortality in the ED in patients with BTAI.

Wada D, Nakamori Y, Kanayama S, Maruyama S, Kawada M, Iwamura H, Hayakawa K, Saito F, Kuwagata Y. First installation of a dual-room IVR-CT system in the emergency room. Scand J Trauma Resusc Emerg Med 2018; 26:17. [PMID: 29506552 PMCID: PMC5836362 DOI: 10.1186/s13049-018-0484-3] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2017] [Accepted: 02/27/2018] [Indexed: 11/26/2022] Open
Abstract
Computed tomography (CT) embedded in the emergency room has gained importance in the early diagnostic phase of trauma care. In 2011, we implemented a new trauma workflow concept with a sliding CT scanner system with interventional radiology features (IVR-CT) that allows CT examination and emergency therapeutic intervention without relocating the patient, which we call the Hybrid emergency room (Hybrid ER). In the Hybrid ER, all life-saving procedures, CT examination, damage control surgery, and transcatheter arterial embolisation can be performed on the same table. Although the trauma workflow realized in the Hybrid ER may improve mortality in severe trauma, the Hybrid ER can potentially affect the efficacy of other in/outpatient diagnostic workflow because one room is occupied by one severely injured patient undergoing both emergency trauma care and CT scanning for long periods. In July 2017, we implemented a new trauma workflow concept with a dual-room sliding CT scanner system with interventional radiology features (dual-room IVR-CT) to increase patient throughput. When we perform emergency surgery or interventional radiology for a severely injured or ill patient in the Hybrid ER, the sliding CT scanner moves to the adjacent CT suite, and we can perform CT scanning of another in/outpatient. We believe that dual-room IVR-CT can contribute to the improvement of both the survival of severely injured or ill patients and patient throughput.

Traumatic brain injury: Comparison between autopsy and ante-mortem CT. J Forensic Leg Med 2017; 52:62-69. [PMID: 28866283 DOI: 10.1016/j.jflm.2017.08.007] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2016] [Revised: 05/27/2017] [Accepted: 08/23/2017] [Indexed: 12/09/2022]
Abstract
PURPOSE The aim of this study was to compare pathological findings after traumatic brain injury between autopsy and ante-mortem computed tomography (CT). A second aim was to identify changes in these findings between the primary posttraumatic CT and the last follow-up CT before death. METHODS Through the collaboration between clinical radiology and forensic medicine, 45 patients with traumatic brain injury were investigated. These patients had undergone ante-mortem CT as well as autopsy. During autopsy, the brain was cut in fronto-parallel slices directly after removal without additional fixation or subsequent histology. Typical findings of traumatic brain injury were compared between autopsy and radiology. Additionally, these findings were compared between the primary CT and the last follow-up CT before death. RESULTS The comparison between autopsy and radiology revealed a high specificity (≥80%) in most of the findings. Sensitivity and positive predictive value were high (≥80%) in almost half of the findings. Sixteen patients had undergone craniotomy with subsequent follow-up CT. Thirteen conservatively treated patients had undergone a follow-up CT. Comparison between the primary CT and the last ante-mortem CT revealed marked changes in the presence and absence of findings, especially in patients with severe traumatic brain injury requiring decompression craniotomy. CONCLUSION The main pathological findings of traumatic brain injury were comparable between clinical ante-mortem CT examinations and autopsy. Comparison between the primary CT after trauma and the last ante-mortem CT revealed marked changes in the findings, especially in patients with severe traumatic brain injury. Hence, clinically routine ante-mortem CT should be included in the process of autopsy interpretation.

Abstract
BACKGROUND Traumatic injury is the third leading cause of death overall. To optimize the outcomes in these patients, hospitals employ whole-body computed tomography (WBCT) imaging due to the high diagnostic yield and potential to identify missed injuries. However, this delays time-critical interventions. Currently, there is an absence of any high-level evidence to support or refute either view. We present a meta-analysis of the available literature to elucidate the efficacy of WBCT in improving the outcomes of trauma, specifically the mortality rate. METHODS A systematic review of studies comparing WBCT and selective CT imaging in secondary survey was conducted, using MEDLINE, EMBASE, the Cochrane Review and Scopus databases. The articles were evaluated for intervention using WBCT to reduce mortality rate, followed by subgroup analysis for other secondary measures, using Review Manager 5.3 software. RESULTS Eleven studies of 32,207 patients were included. There were lower overall (OR=0.79; 95% CI 0.74,0.83, p<0.05) and 24h mortality rates (OR=0.72, 95% CI 0.66,0.79, p<0.05) in the WBCT cohort. Additionally, patients in the WBCT arm spent less time in the emergency room (MD=-14.81; 95% CI -17.02, -12.60, p<0.00001) and needing ventilation (MD=-2.01; 95% CI -2.41, -1.62, p<0.05) despite a higher baseline injury severity score. CONCLUSION The analysis shows that WBCT is associated with better outcomes, including a lower overall and 24h mortality rate, however the included studies are mostly observational and show considerable heterogeneity. Further work is required to make definitive clinical recommendations for a tailored algorithm in managing trauma patients.

Abstract
Noncompressible torso hemorrhage (NCTH) constitutes a leading cause of potentially preventable trauma mortality. NCTH is defined by high-grade injury present in one or more of the following anatomic domains: pulmonary, solid abdominal organ, major vascular or pelvic trauma; plus hemodynamic instability or the need for immediate hemorrhage control. Rapid operative management, as part of a damage control resuscitation strategy, remains the mainstay of treatment. However, endovascular techniques are evolving and may become more mainstream with the advent of hybrid rooms that can deliver concurrent open and radiologic/endovascular management of traumatic hemorrhage.

Whole body CT versus selective radiological imaging strategy in trauma: an evidence-based clinical review. Am J Emerg Med 2017; 35:1356-1362.

Abstract
BACKGROUND Trauma patients often present with injuries requiring resuscitation and further evaluation. Many providers advocate for whole body computed tomography (WBCT) for rapid and comprehensive diagnosis of life-threatening injuries. OBJECTIVE Evaluate the literature concerning mortality effect, emergency department (ED) length of stay, radiation, and incidental findings associated with WBCT. DISCUSSION Physicians have historically relied upon history and physical examination to diagnose life-threatening injuries in trauma. Diagnostic imaging modalities including radiographs, ultrasound, and computed tomography have demonstrated utility in injury detection. Many centers routinely utilize WBCT based on the premise this test will improve mortality. However, WBCT may increase radiation and incidental findings when used without considering pre-test probability of actionable traumatic injuries. Studies supporting WBCT are predominantly retrospective and incorporate trauma scoring systems, which have significant design weaknesses. The recent REACT-2 trial randomized trauma patients with high index of suspicion for actionable injuries to WBCT versus selective imaging and found no mortality difference. Additional prospective trials evaluating WBCT in specific trauma subgroups (e.g. polytrauma) are needed to evaluate benefit. In the interim, the available data suggests clinicians should adopt a selective imaging strategy driven by history and physical examination. CONCLUSIONS While observational data suggests an association between WBCT and a benefit in mortality and ED length of stay, randomized controlled data suggests no mortality benefit to this diagnostic tool. The literature would benefit from confirmatory studies of the use of WBCT in trauma sub-groups to clarify its impact on mortality for patients with specific injury patterns.

Abstract
BACKGROUND Published work suggests a survival benefit for patients with trauma who undergo total-body CT scanning during the initial trauma assessment; however, level 1 evidence is absent. We aimed to assess the effect of total-body CT scanning compared with the standard work-up on in-hospital mortality in patients with trauma. METHODS We undertook an international, multicentre, randomised controlled trial at four hospitals in the Netherlands and one in Switzerland. Patients aged 18 years or older with trauma with compromised vital parameters, clinical suspicion of life-threatening injuries, or severe injury were randomly assigned (1:1) by ALEA randomisation to immediate total-body CT scanning or to a standard work-up with conventional imaging supplemented with selective CT scanning. Neither doctors nor patients were masked to treatment allocation. The primary endpoint was in-hospital mortality, analysed in the intention-to-treat population and in subgroups of patients with polytrauma and those with traumatic brain injury. The χ(2) test was used to assess differences in mortality. This trial is registered with ClinicalTrials.gov, number NCT01523626. FINDINGS Between April 22, 2011, and Jan 1, 2014, 5475 patients were assessed for eligibility, 1403 of whom were randomly assigned: 702 to immediate total-body CT scanning and 701 to the standard work-up. 541 patients in the immediate total-body CT scanning group and 542 in the standard work-up group were included in the primary analysis. In-hospital mortality did not differ between groups (total-body CT 86 [16%] of 541 vs standard work-up 85 [16%] of 542; p=0.92). In-hospital mortality also did not differ between groups in subgroup analyses in patients with polytrauma (total-body CT 81 [22%] of 362 vs standard work-up 82 [25%] of 331; p=0.46) and traumatic brain injury (68 [38%] of 178 vs 66 [44%] of 151; p=0.31). Three serious adverse events were reported in patients in the total-body CT group (1%), one in the standard work-up group (<1%), and one in a patient who was excluded after random allocation. All five patients died. INTERPRETATION Diagnosing patients with an immediate total-body CT scan does not reduce in-hospital mortality compared with the standard radiological work-up. Because of the increased radiation dose, future research should focus on the selection of patients who will benefit from immediate total-body CT.

Abstract
PURPOSE Total-body CT scanning (TBCT) could improve the initial in-hospital evaluation of severe trauma patients. Indications for TBCT, however, differ between trauma centers, so more insight in how to select patients that could benefit from TBCT is required. The aim of this review was to give an overview of currently used indications for total-body CT in trauma patients and to describe mortality and Injury Severity Scores of patient groups selected for TBCT. METHODS A systematic review was performed by searching MEDLINE and Embase databases. Studies evaluating or describing criteria for selection of patients with potentially severe injuries for TBCT during initial trauma care were included. Also, studies comparing total-body CT during the initial assessment of injured patients with conventional imaging and selective CT in specific patient groups were included. RESULTS Thirty eligible studies were identified. Three studies evaluated indications for TBCT in trauma with divergent methods. Combinations of compromised vital parameters, severe trauma mechanisms and clinical suspicion on severe injuries are often used indications; however, clinical judgement is used as well. Studies describing TBCT indications selected patients in different ways and were difficult to compare regarding mortality and injury severity. CONCLUSIONS Indications for TBCT in trauma show a wide variety in structure and cut-off values for vital parameters and trauma mechanism dimensions. Consensus on indications for TBCT in trauma is lacking.

Abstract
This article describes the theory of the formation of the vacuum phenomenon (VP), the detection of the VP, the different medical causes, the different locations of the presentation of the VP, and the differential diagnoses. In the human body, the cavitation effect is recognized on radiological studies; it is called the VP. The mechanism responsible for the formation of the VP is as follows: if an enclosed tissue space is allowed to expand as a rebound phenomenon after an external impact, the volume within the enclosed space will increase. In the setting of expanding volume, the pressure within the space will decrease. The solubility of the gas in the enclosed space will decrease as the pressure of the space decreases. Decreased solubility allows a gas to leave a solution. Clinically, the pathologies associated with the VP have been reported to mainly include the normal joint motion, degeneration of the intervertebral discs or joints, and trauma. The frequent use of CT for trauma patients and the high spatial resolution of CT images might produce the greatest number of chances to detect the VP in trauma patients. The VP is observed at locations that experience a traumatic impact; thus, an analysis of the VP may be useful for elucidating the mechanism of an injury. When the VP is located in the abdomen, it is important to include perforation of the digestive tract in the differential diagnosis. The presence of the VP in trauma patients does not itself influence the final outcome.

Abstract
Acute vascular injuries are the second most common cause of fatalities in patients with multiple traumatic injuries; thus, prompt identification and management is essential for patient survival. Over the past few years, multidetector CT (MDCT) using dual-phase scanning protocol has become the imaging modality of choice in high-energy deceleration traumas. The objective of this article was to review the role of dual-phase MDCT in the identification and management of acute vascular injuries, particularly in the chest and abdomen following multiple traumatic injuries. In addition, this article will provide examples of MDCT features of acute vascular injuries with correlative surgical and interventional findings.

Abstract
BACKGROUND The recommendations still have to be implemented 3 years after publication of the S3 guidelines on the treatment of patients with severe and multiple injuries. AIM This article reiterates some of the essential core statements of the S3 guidelines and also gives an overview of new scientific studies. MATERIAL AND METHODS In a selective literature search new studies on airway management, traumatic cardiac arrest, shock classification, coagulation therapy, whole-body computed tomography, air rescue and trauma centers were identified and are discussed in the light of the S3 guideline recommendations. RESULTS The recommendations on airway management are up to date; however, recommendations on difficult airway evaluation tools, e.g. the LEMON law, should be included. The first pass success (i.e. intubation success at the first attempt) must be considered as a quality marker in the future. Video laryngoscopy is identified as a leading airway procedure in order to reach this aim. Recently estimated learning curves for endotracheal intubation and supraglottic airway devices should be implemented in qualification statements. Life-saving emergency interventions have to be performed in the prehospital setting as they do not prolong the complete treatment period for severely injured patients up to discharge from the resuscitation room. The outcome of patients suffering from traumatic cardiac arrest is better than expected. Recently developed algorithms for trauma patients have to be implemented. The prehospital trauma life support (PHTLS) and advanced trauma life support (ATLS) shock classification does not reflect the clinical reality; therefore, lactate, lactate clearance and base deficit should be used for evaluating the shock state in the resuscitation room. Concerning coagulation therapy, tranexamic acid is easy to administer, safe and effective as an antifibrinolytic therapy and should not be restricted to the most severely injured patients. Numerous studies have shown the positive effect of whole-body computed tomography on treatment time and outcome; however, clear indications for the use of whole-body computed tomography are lacking. Further investigations supported the positive effects of air rescue on the treatment outcome of trauma patients. CONCLUSION The recommendations on interdisciplinary trauma management contained in the S3 guidelines on the treatment of patients with severe and multiple injuries should be implemented into the clinical routine. Additionally, the knowledge gained from more recent scientific studies is necessary for anesthetists and emergency physicians to be able to adequately implement the core statements of the S3 guidelines for the treatment of patients with severe and multiple injuries.

[PMID: 26104319 PMCID: PMC4522317 DOI: 10.5249/jivr.v7i2.613] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2014] [Accepted: 07/10/2014] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND The initial diagnostic evaluation and management of trauma patients is mainly based on Advanced Trauma Life Support (ATLS) guidelines worldwide. Based on ATLS principles, conventional diagnostics such as conventional radiography (CR) and focused abdominal sonography in trauma (FAST) should precede selective use of CT. Whole-body CT (WBCT) is highly accurate and allows detection of life threatening injuries with good sensitivity and specificity. WBCT is faster than conventional diagnostics and saves more time in management of trauma patients. This study aims to review studies investigating the effect of WBCT on mortality in trauma patients. METHODS Literatures were found by searching keywords in Medline, PubMed and Cochrane library. The relevant articles were selected by two independent reviewers based on title, abstract and introduction sections. Full-texts of selected articles were reviewed and those investigating effect of WBCT on mortality in trauma patients were included. RESULTS Searching the keywords in Medline and PubMed resulted in 178 and 167 articles, respectively. Nine studies met the inclusion criteria and were reviewed. These included 8 retrospective and 1 prospective cohort studies. Mortality was measured as mortality rate or standardised mortality ratio (SMR) in the included studies. CONCLUSIONS Unlike previous systematic reviews, this review indicates that use of WBCT in blunt trauma patients is associated with reduced overall mortality rate and that WBCT can potentially improve the probability of survival in haemodynamically stable and unstable blunt trauma patients. High quality RCTs are required to describe a causal relationship between WBCT and mortality in trauma patients.

Abstract
A retrospective review of case notes and radiology records was performed in order to estimate the amount and sources of ionising radiation multiply injured trauma patients are exposed to, during their initial investigations and subsequent critical care admission. Data were available for 431 radiological investigations from 36 patients. Results showed initial emergency department imaging (combined computed tomography (CT) and plain radiographs) contributed 70% of the total radiation dose. Overall, CT scans were responsible for 80% and plain radiographs 15% of the total radiation dose. Plain radiographs performed after the initial resuscitation period contributed the greatest number of investigations but accounted for only 8% of total radiation exposure. Median cumulative effective dose was estimated to be between 16 and 29 millisieverts, resulting in an estimated increased life time risk of carcinogenesis of between 1 in 614 and 1 in 1075 above baseline.

Significance of the vacuum phenomenon in patients with trauma evaluated by whole-body computed tomography. Am J Emerg Med 2014; 33:282-5. [PMID: 25530190 DOI: 10.1016/j.ajem.2014.11.055] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2014] [Revised: 11/18/2014] [Accepted: 11/29/2014] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND Severely traumatized patients undergo whole-body computed tomography (WCT) to detect lethal anatomical injuries. When checking the images, we have sometimes recognized minute gas (the vacuum phenomenon [VP]) near the traumatized lesions. Accordingly, we investigated the significance of the VP in patients with trauma. BASIC PROCEDURES From April to October 2013, a medical record review was retrospectively performed for all patients with trauma. The exclusion criteria included an age more than 60 years, patients who did not receive the WCT, scan and those in cardiopulmonary arrest on arrival. The subjects were divided into 2 groups: a VP group (n=19), which included patients who had the VP, and a control group (n=49). MAIN FINDINGS There were no significant differences between the 2 groups with regard to age, the mechanism of injury, or the survival rate. In contrast, the ratio of women, the Injury Severity Score, and the duration of hospitalization in the VP group were significantly higher than those in the control group. The greatest number of the VP was located at or near rib fractures, followed by joint spaces that experienced a traumatic impact. PRINCIPAL CONCLUSION This study demonstrated that the VP tended to be observed most often in severely traumatized female cases. The VP is observed at locations that experience a traumatic impact, so an analysis of the VP may be useful to elucidate the mechanism of injuries. The presence of traumatic VP itself does not influence the final outcome.

Abstract
Traumatic injuries represent a major health problem all over the world. In recent years we have witnessed profound changes in the paradigm of severe trauma patient resuscitation, new concepts regarding acute coagulopathy in trauma have been proposed, and there has been an expansion of specific commercial products related to hemostasis, among other aspects. New strategies in severe trauma management include the early identification of those injuries that are life threatening and require surgical hemostasis, tolerance of moderate hypotension, rational intravascular volume replacement, prevention of hypothermia, correction of acidosis, optimization of oxygen carriers, and identification of those factors required by the patient (fresh frozen plasma, platelets, tranexamic acid, fibrinogen, cryoprecipitates and prothrombin complex). However, despite such advances, further evidence is required to improve survival rates in severe trauma patients.

Abstract
In the treatment of severely injured patients, the term 'damage control radiology' has been used to parallel the modern concept of damage control surgery and the allied development of continuous damage control resuscitation from patient retrieval, through all transfers, to appropriate primary treatment. The aims of damage control radiology are (i) rapid identification of life-threatening injuries including bleeding sites, (ii) identification or exclusion of head or spinal injury, and (iii) prompt and accurate triage of patients to the operating theatre for thoracic, abdominal, or both surgeries or the angiography suite for endovascular haemorrhage control. If we are to achieve these aims, patients must have immediate access to modern multidetector computed tomography (MDCT) which is without doubt the most potent weapon in the diagnostic armamentarium. The most severely injured patients are those who have the most to benefit from early diagnosis and life-saving therapies. The traditional teaching that these patients should go immediately to surgery is challenged by technological developments in MDCT and recent clinical evidence.

Scand J Trauma Resusc Emerg Med 2014; 22:54. [PMID: 25178942 PMCID: PMC4347587 DOI: 10.1186/s13049-014-0054-2] [Citation(s) in RCA: 73] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2014] [Accepted: 08/25/2014] [Indexed: 11/10/2022] Open
Abstract
Introduction The purpose of this meta-analysis was to explore the value of whole-body computed tomography (WBCT) in major trauma patients (MTPs). Methods A comprehensive search for articles from Jan 1, 1980 to Dec 31, 2013 was conducted through PubMed, Cochrane Library database, China biology medical literature database, Web of knowledge, ProQuest, EBSCO, OvidSP, and ClinicalTrials.gov. Studies which compared whole-body CT with conventional imaging protocol (X-ray of the pelvis and chest, trans-abdominal sonography, and/or selective CT) in MTPs were eligible. The primary endpoint was all-cause mortality. The second endpoints included: time spent in the emergency department (ED), the duration of mechanical ventilation, ICU and hospital length of stay (LOS), the incidence of Multiple Organ Dysfunction Syndrome (MODS) /Multiple Organ Failure (MOF). Analysis was performed with Review Manager 5.2.10 and Stata 12.0. Results Eleven trials enrolling 26371 patients were analyzed. In MTPs, the application of WBCT was associated with lower mortality rate (pooled OR: 0.66, 95% CI: 0.52 to 0.85) and a shorter stay in the ED (weighted mean difference (WMD), −27.58 min; 95% CI, −43.04 to −12.12]. There was no effect of WBCT on the length of ICU stay (WMD, 0.95 days; 95% CI: −0.08 to 1.98) and the length of hospital stay (WMD, 0.56 days; 95% CI: −0.03 to 1.15). Patients in the WBCT group had a longer duration of mechanical ventilation (WMD, 0.96 days, 95% CI: 0.32 to 1.61) and higher incidence of MODS/MOF (OR, 1.44, 95% CI: 1.35-1.54; P = 0.00001). Conclusions The present meta-analysis suggests that the application of whole-body CT significantly reduces the mortality rate of MTPs and markedly reduces the time spent in the emergency department.

Topogram-based automated selection of the tube potential and current in thoraco-abdominal trauma CT - a comparison to fixed kV with mAs modulation alone. Eur Radiol 2014; 24:1725-34. [PMID: 24816940 DOI: 10.1007/s00330-014-3197-7] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2013] [Revised: 03/15/2014] [Accepted: 04/22/2014] [Indexed: 11/26/2022]
Abstract
OBJECTIVE To investigate the impact of automated attenuation-based tube potential selection on image quality and exposure parameters in polytrauma patients undergoing contrast-enhanced thoraco-abdominal CT. METHODS One hundred patients were examined on a 16-slice device at 120 kV with 190 ref.mAs and automated mA modulation only. Another 100 patients underwent 128-slice CT with automated mA modulation and topogram-based automated tube potential selection (autokV) at 100, 120 or 140 kV. Volume CT dose index (CTDI(vol)), dose-length product (DLP), body diameters, noise, signal-to-noise ratio (SNR) and subjective image quality were compared. RESULTS In the autokV group, 100 kV was automatically selected in 82 patients, 120 kV in 12 patients and 140 kV in 6 patients. Patient diameters increased with higher kV settings. The median CTDI(vol) (8.3 vs. 12.4 mGy; -33%) and DLP (594 vs. 909 mGy cm; -35%) in the entire autokV group were significantly lower than in the group with fixed 120 kV (p < 0.05 for both). Image quality remained at a constantly high level at any selected kV level. CONCLUSION Topogram-based automated selection of the tube potential allows for significant dose savings in thoraco-abdominal trauma CT while image quality remains at a constantly high level. KEY POINTS • Automated kV selection in thoraco-abdominal trauma CT results in significant dose savings • Most patients benefit from a 100-kV protocol with relevant DLP reduction • Constantly good image quality is ensured • Image quality benefits from higher kV when arms are positioned downward.

Abstract
Ellagic acid, a naturally occurring polyphenol was encapsulated in chitosan particles prepared by ionotropic gelation and characterized for its physicochemical properties. A maximum encapsulation efficiency of 49% was achieved. The blood clotting time and clot retraction time were calculated for different concentrations of ellagic acid, chitosan and ellagic acid-encapsulated chitosan. A reduction of 34% in the clot time and 16.4% in the retraction time was observed in ellagic acid-encapsulated chitosan when compared with free ellagic acid at concentrations as low as 0.1mg/mL. The physical blend in comparison to free ellagic acid displayed a reduction of 13.8% and 4.6% in the clotting time and retraction time respectively under similar conditions. This suggests that the encapsulation of ellagic acid favors thrombosis due to synergistic action of chitosan and ellagic acid on same molecular targets. This study demonstrates the potential of ellagic acid-chitosan system as an effective anti-hemorrhagic system.
