Abstract
BACKGROUND Blunt cardiac injury (BCI) has a variety of symptoms that may be a potentially life-threatening injury that can lead to death. Depending on the diagnosis of BCI, treatment direction and length of stay may vary. In addition, the utility of other diagnostic tests for cardiac disease as diagnostic tools for BCI remain unclear. The purpose of this study was to investigate the competence of N-terminal pro-B-type natriuretic peptide (NT pro-BNP) and cardiac index (C.I) as adjunctive diagnostic tools for BCI. METHODS From January 2018 to March 2020, severe trauma patients with sternum fracture who were admitted to the traumatic intensive care unit (TICU) were included this study. Patients with sternum fracture, 18 years of age or older, and with an injury severity score > 16 who required intensive care were included. Invasive measurement for the analysis of the pulse contour for C.I monitoring and intravenous blood sampling for NT pro-BNP measurement were performed. Sampling and 12-lead electrocardiogram were performed at different time points as follows: immediately after TICU admission and at 24 h and 48 h after trauma. RESULTS Among 103; 33 patients with factors that could affect NT pro-BNP were excluded; therefore, 63 patients were included in this study. According to the American Association for the Surgery of Trauma Cardiac Injury Scale, 33 patients were diagnosed with non-BCI, and 30 patients constituted with BCI. The median ages of the patients were 58 (52-69), and 60 (45-69) years in the non-BCI and BCI groups, respectively (p = 0.77). The median NT pro-BNP values were higher in the BCI group on admission, hospital day (HD) 2, and HD 3, however, no statistical difference was observed (125 (49-245) vs. 130 (47-428) pg/mL, p = 0.08, 124 (68-224) vs. 187 (55-519) pg/mL, p = 0.09, and 121(59-225) vs. 133 (56-600) pg/mL, p = 0.17, respectively). On the contrary, significantly lower values were observed in the median C.I measurement on admission and HD 3 in the BCI group (3.2 (2.8-3.5) vs. 2.6 (2.3-3.5) L/min/m2, p < 0.01 and 3.2 (3.1-3.9) vs. 2.9 (2.4-3.2) L/min/m2, p < 0.01, respectively); however, no significant difference was observed on HD 2 (3.4 (3.0-3.7) vs. 2.6 (2.4-3.4) L/min/m2, p = 0.17), Furthermore, The median lactate levels in the BCI group upon admission, HD 2, and HD 3 were significantly higher than those in the non-BCI group (1.8 (1.1-2.6) vs. 3.1 (2.1-4.4) mmol/L, p < 0.01; 1.3 (0.8-2.3) vs. 3.0 (2.2-4.7) mmol/L, p < 0.01; and 1.5 (0.9-1.5) vs. 2.2 (1.3-3.7) mmol/L, p < 0.01, respectively). CONCLUSION Consecutive values of NT pro-BNP and C.I show no correlation with ECG-based BCI diagnosis. However, lactate level measurement may help in the early recognition of BCI as an adjunctive tool. It should be noted that this is a hypothesis-generating study for BCI diagnosis. Further studies should be conducted in larger populations with a prospective approach.

Abstract
Since the early 1990s, video-assisted thoracoscopy (VATS) has been increasingly established for a variety of indications in the treatment of patients with thoracic trauma. During this time, one premise for the use of thoracoscopy has not changed. Its use is consistently recommended only for trauma patients with stable circulation and respiration. To define the indications of VATS for use in thoracic trauma, the Pulmonary Injury Group - as part of the Working Committee for Thoracic Trauma of the German Society for Thoracic Surgery (DGT) and the German Society for Trauma Surgery (DGU) - has developed treatment recommendations based on a current literature review (based on the PRISMA Checklist/here: MEDLINE via PubMed from 1993 to 2022). In the present study, after reviewing the available literature, the indications for VATS in the care of thoracic trauma were identified, in order to formulate clinical recommendations for the use of VATS in thoracic trauma. The analysis of 1679 references identified a total of 4 randomised controlled trials (RCTs), 4 clinical trials, and 5 meta-analyses or systematic reviews and 39 reviews, which do not allow a higher level of recommendation than consensual recommendations, due to the low evidence of the available literature. Over the past 30 years, stabilisation options in the care of trauma patients have improved significantly, allowing expansion of indications for the use of VATS. Moreover, the recommendation for more than 50 years to thoracotomise trauma patients in case of an initial blood loss ≥ 1500 ml via the inserted chest drainage or in case of continuous blood loss ≥ 250 ml/h over 4 h is now only relative with today's better stabilisation measures. For unstable/non-stabilisable patients with a thoracic injury requiring emergency treatment, thoracotomy remains the method of choice, while VATS is recommended for a wide range of indications in the diagnosis and treatment of stable patients with a penetrating or blunt thoracic trauma. The indications for VATS are persistent haemothorax, treatment of injuries and haemorrhages to the lung, diaphragm, thoracic wall and other organ injuries, and in the secondary phase, treatment of thoracic sequelae of injury (empyema, persistent pulmonary fistula, infected atelectasis, etc.).

Diagnostic value of chest radiography in the early management of severely injured patients with mediastinal vascular injury. Eur J Trauma Emerg Surg 2022; 48:4223-4231. [PMID: 35389063 PMCID: PMC9532297 DOI: 10.1007/s00068-022-01966-3] [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: 12/16/2021] [Accepted: 03/23/2022] [Indexed: 11/12/2022]
Abstract
Introduction Time is of the essence in the management of severely injured patients. This is especially true in patients with mediastinal vascular injury (MVI). This rare, yet life threatening injury needs early detection and immediate decision making. According to the ATLS guidelines [American College of Surgeon Committee on Trauma in Advanced Trauma Life Support (ATLS®), 10th edn, 2018], chest radiography (CXR) is one of the first-line imaging examinations in the Trauma Resuscitation Unit (TRU), especially in patients with MVI. Yet thorough interpretation and the competence of identifying pathological findings are essential for accurate diagnosis and drawing appropriate conclusion for further management. The present study evaluates the role of CXR in detecting MVI in the early management of severely injured patients. Method We addressed the question in two ways. (1) We performed a retrospective, observational, single-center study and included all primary blunt trauma patients over a period of 2 years that had been admitted to the TRU of a Level-I Trauma Center. Mediastinal/chest (M/C) ratio measurements were calculated from CXRs at three different levels of the mediastinum to identify MVI. Two groups were built: with MVI (VThx) and without MVI (control). The accuracy of the CXR findings were compared with the results of whole-body computed tomography scans (WBCT). (2) We performed another retrospective study and evaluated the usage of sonography, CXR and WBCT over 15 years (2005–2019) in level-I–III Trauma Centers in Germany as documented in the TraumaRegister DGU® (TR-DGU). Results Study I showed that in 2 years 267 patients suffered from a significant blunt thoracic trauma (AIS ≥ 3) and met the inclusion criteria. 27 (10%) of them suffered MVI (VThx). Through the initial CXR in a supine position, MVI was detected in 56–92.6% at aortic arch level and in 44.4–100% at valve level, depending on different M/C-ratios (2.0–3.0). The specificity at different thresholds of M/C ratio was 63.3–2.9% at aortic arch level and 52.9–0.4% at valve level. The ROC curve showed a statistically random process. No significant differences of the cardiac silhouette were observed between VThx and Control (mean cardiac width was 136.5 mm, p = 0.44). Study II included 251,095 patients from the TR-DGU. A continuous reduction of the usage of CXR in the TRU could be observed from 75% in 2005 to 25% in 2019. WBCT usage increased from 35% in 2005 to 80% in 2019. This development was observed in all trauma centers independently from their designated level of care. Conclusion According to the TRU management guidelines (American College of Surgeon Committee on Trauma in Advanced Trauma Life Support (ATLS®), 10th edn, 2018; Reissig and Kroegel in Eur J Radiol 53:463–470, 2005) CXR in supine position is performed to detect pneumothorax, hemothorax and MVI. Our study showed that sensitivity and specificity of CXR in detecting MVI was statistically and clinically not reliable. Previous studies have already shown that CXR is inferior to sonography in detecting pneumothorax and hemothorax. Therefore, we challenge the guidelines and suggest that the use of CXR in the early management of severely injured patients should be individualized. If sonography and WBCT are available and reasonable, CXR is unnecessary and time consuming. The clinical reality reflected in the usage of CXR and WBCT over time, as documented in the TR-DGU, seems to support our statement.

Abstract
We present a case report of an otherwise healthy 37-year-old male without pertinent cardiac history or risk factors, who presented with cardiac trauma after a motor vehicle collision (MVC). Initial workup including electrocardiogram (ECG), transthoracic echocardiogram (TTE), and uptrending serial troponins warranted coronary angiography, during which occlusive thrombi were discovered in the proximal right coronary artery (pRCA), the right posterolateral vessel (rPL), and the right posterior descending artery (PDA). Subsequently, the patient underwent percutaneous coronary intervention of the RCA and PDA with aspiration thrombectomy. He was then initiated on dual antiplatelet therapy (DAPT) and recovered appropriately. This case is presented with the goal of enlightening the academic community of a rare complication while presenting a judicious approach to management in an attempt to decrease the occurrence of “near misses” in the future.

Abstract
Purpose Myocardial contusion can be a life-threatening condition in patients who sustained blunt thoracic trauma. The diagnostic approach remains a subject of debate. The aim of this study was to determine the sensitivity and specificity of echocardiography, electrocardiography, troponins T and I (TnT and TnI), and creatine kinase muscle/brain (CK-MB) for identifying patients with a myocardial contusion following blunt thoracic trauma. Methods Sensitivity and specificity were first determined in a 10-year retrospective cohort study and second by a systematic literature review with meta-analysis. Results Of the 117 patients in the retrospective study, 44 (38%) were considered positive for myocardial contusion. Chest X-ray, chest CT scan, electrocardiograph, and echocardiography had poor sensitivity (< 15%) but good specificity (≥ 90%). Sensitivity to cardiac biomarkers measured at presentation ranged from 59% for TnT to 77% for hs-TnT, specificity ranged from 63% for CK-MB to 100% for TnT. The systematic literature review yielded 28 studies, with 14.5% out of 7242 patients reported as positive for myocardial contusion. The pooled sensitivity of electrocardiography, troponin I, and CK-MB was between 62 and 71%, versus only 45% for echocardiography and 38% for troponin T. The pooled specificity ranged from 63% for CK-MB to 85% for troponin T and 88% for echocardiography. Conclusion The best diagnostic approach for myocardial contusion is a combination of electrocardiography and measurement of cardiac biomarkers. If abnormalities are found, telemonitoring is necessary for the early detection of life-threatening arrhythmias. Chest X-ray and CT scan may show other thoracic injuries but provide no information on myocardial contusion.

Abstract
Modern trauma room management requires interdisciplinary teamwork and synchronous communication between a team of anaesthesists, surgeons and radiologists. As the length of stay in the trauma room influences morbidity and mortality of a severely injured person, optimizing time is one of the main targets. With the direct involvement of modern imaging techniques the injuries caused by trauma should be detected within a very short period of time in order to enable a priority-orientated treatment. Radiology influences structure and process quality, management and development of trauma room algorithms regarding the use of imaging techniques. For the individual case interventional therapy methods can be added. Based on current data and on the Frankfurt experience the current diagnostic concepts of trauma diagnostics are presented.

Abstract
Trauma is the leading cause of death worldwide. Approximately 2/3 of the patients have a chest trauma with varying severity from a simple rib fracture to penetrating injury of the heart or tracheobronchial disruption. Blunt chest trauma is most common with 90% incidence, of which less than 10% require surgical intervention of any kind. Mortality is second highest after head injury, which underlines the importance of initial management. Many of these deaths can be prevented by prompt diagnosis and treatment. What is the role of the thoracic surgeon in the management of chest trauma in severely injured patients? When should the thoracic surgeon be involved? Is there a place for minimal invasive surgery in the management of severely injured patients? With two case reports we would like to demonstrate how the very specific knowledge of thoracic surgeons could help in the care of trauma patients.

Abstract
OBJECTIVES Pulmonary contusion (PC) is common in cases of polytrauma. The aim of this study was to perform a multivariate analysis of risk factors associated with the occurrence of infection in PC and analyze the microbiological epidemiology. PATIENTS AND METHODS All patients with PC admitted to the intensive care unit (ICU) between January 2002 and December 2006 were included in this retrospective observational study. Patients with penetrating thoracic trauma or those who died in the 48hours following admission to hospital were excluded. Diagnosis of bacterial infection in PC was performed if hyperthermia was associated with a positive quantitative culture (103 colony forming units/mL) on the bronchial sample. Univariate analysis provided statistical difference between variables that were integrated in the multivariate analysis model. Multivariate analysis was then performed to determine the risk factors of bacterial infection in PC. RESULTS One hundred and seventeen patients were included. The incidence of bacterial infection in PC was 33.3% (39 patients). The most frequently encountered bacteria were Haemophilus sp., Staphylococcus aureus, Enterobacteriaceae, Pseudomonas sp. and Streptococcus sp. According to multivariate analysis, the existence of hypothermia at hospital admission increased the risk of PC infection (OR=2.61; IC 95% [4.2-13.3]). CONCLUSION In conclusion, PC was infected in 33.3% of cases. The existence of hypothermia was identified as a risk factor. A prospective study is warranted to confirm these results.

Abstract
The diagnosis of myocardial contusion in the setting of blunt trauma engenders much discussion and controversy-partly because of the lack of a gold standard for its identification other than histologic findings at autopsy. Furthermore, blunt cardiac trauma represents a spectrum of disorders ranging from transient electrocardiographic change to sudden death from myocardial rupture; hence, no single terminology exists to define such a wide range of scenarios. Here, we present 2 cases of electrocardiographic ST-segment elevation after high-speed motor vehicle crashes resulting in numerous injuries, including blunt chest trauma. Both patients demonstrated electrocardiographic ST-segment elevation, resulting from myocardial contusion and acute myocardial infarction.

Abstract
OBJECTIVE Injuries to the chest contribute significantly to the morbidity and mortality in multiple injured patients. This systematic review focuses on evidence based initial diagnostics and emergency room management of chest trauma. METHODS Clinical trials was systematically collected (Medline, Cochrane and hand searches) and classified into evidence levels (1 to 5 according to the Oxford system). RESULTS There are only a few studies that document the impact of injury mechanism and clinical examination of the patient. There is a positive correlation between crash severity or lateral impact with injury severity. Auscultation was found to be very sensitive in the detection of pneumothorax. Helical CT of the chest is most important in the initial work-up. Aortography is only indicated in selected cases. Whether tube thoracostomy is necessary in patients with occult pneumotharaces is still a matter of discussion. Indications for endotracheal intubation are poorly investigated and predominantly based on expert opinion. CONCLUSION Numerous comparative studies (LE 2) dealing with emergency diagnostics and therapy of chest trauma are available, however only a few randomized studies do exist. Based on the available data a rational therapy of chest trauma is possible.

Abstract
BACKGROUND Myocardial contusion during blunt chest trauma is common and may lead to potentially fatal cardiac complications. Therefore, it is useful to identify a serum marker reflecting the myocardial damage that can predict risk for cardiac complications. In this study, the authors determined the strength of the association between cardiac troponin I (cTnI) levels and the risk of arrhythmia or the development of left ventricular dysfunction in a cohort of patients with blunt chest trauma. METHODS AND RESULTS In 187 multiply injured patients with blunt chest trauma, serial measurements of cTnI, total creatine kinase (CK), and isoenzyme of creatine kinase with muscle and brain subunits (CK-MB) were combined with sequential electrocardigraphic and echocardiographic recordings. The results showed that 63 patients (34%) had myocardial contusion, as defined by positive cTnI levels, of which 47 (25%) were symptomatic and 16 (9%) showed no abnormalities. The remaining 124 patients (66%) displaying negative CTnI levels were asymptomatic during the entire study. Severity of arrhythmia correlated directly with increase in cTnI levels. The levels of cTnI in the symptomatic group remained elevated significantly longer than the levels in the asymptomatic group. The depression of left ventricular ejection fraction was inversely correlated with the increase in cTn levels. The patients whose cTnI levels were below 1.05 microg/L at admission and during the first 6 hours afterward showed no cardiac abnormalities throughout the entire study period CONCLUSIONS Levels of cTnI below 1.05 microg/L in asymptomatic patients at admission and within the first 6 hours after admission rule out myocardial injury, whereas positive cTn levels above 1.05 microg/L mandate further cardiologic workup for the detection and management of myocardial injury. Furthermore, the dynamics and peak levels of pathologic cTnI levels allow estimation of arrhythmia risk and left ventricular dysfunction in trauma patients with myocardial contusion.

Abstract
OBJECTIVE To evaluate computed tomography quantification of injured pulmonary volume after thoracic trauma and its relevance for severity grade of patients with lung contusion. STUDY DESIGN Retrospective study in a major French Level I university trauma center. PATIENTS AND METHODS Clinical and biological data including oxygenation index (PaO2/FIO2) and therapeutics modalities during the first 5 days: positive end expiratory pressure (Peep) and nitric oxide (NO), were collected on 49 patients with lung contusion resulting from thoracic trauma. Injured pulmonary volume was evaluated on initial thoracic tomodensitometry by 2 senior radiologists. The correlation between oxygenation index, therapeutics modalities and initial injured pulmonary volume was assessed for signification. RESULTS Injured pulmonary volume larger than 37.75% of total lung volume is associated with both hypoxemia at the twenty-fourth hour (PaO2/FIO2 <300), and need for Peep >6 cm H2O and /or ongoing NO administration on day 5. CONCLUSION Injured parenchymal pulmonary volume evaluation on initial tomodensitometry seems to be an important indicator of lung contusion severity. Thoracic computed tomography provides additional prognostic information in the initial evaluation of thoracic trauma with parenchymal injury.

Abstract
The symptom of chest pain in the athlete can represent anything from a nonspecific musculoskeletal strain to a life-threatening condition such as tension pneumothorax. For the physician charged with evaluating this patient population, a thorough knowledge of the possible etiologies, their usual diagnostic algorithms, available imaging modalities, and potential therapeutic options is essential. Although the vast majority of patients with traumatic chest pain will not harbor significant pathology, the clinician must be prepared for those few who do have such conditions, and be prepared to intervene in an appropriate, time-sensitive fashion.

Abstract
Computed tomography has had a questionable role in diagnosing blunt aortic injury (BAI). The objective of this study was to determine the effectiveness of helical computed tomography of the thorax (HCTT) for detection of BAI. Trauma Registry data and medical records were reviewed for 2,854 patients admitted over a 32-month period. A total of 243 patients were identified at risk for BAI. Patients were evaluated for BAI because of chest radiograph, physical examination, or clinical suspicion. Eleven of 2,834 patients sustained BAI. Of 243 patients who sustained blunt torso trauma, 232 patients underwent HCTT. Eleven underwent aortography without HCTT. Sixteen patients had an abnormal HCTT, revealing 9 patients with BAI. No delayed BAI were encountered. HCTT effectively screens for BAI. Aortography can be more specifically applied as a diagnostic study when preceded by HCTT. HCTT should not be used as solitary study for BAI as some injuries identified by HCTT do not represent BAI.

Abstract
Pulmonary injuries resulting from blunt chest trauma remain a common clinical entity for critical care and emergency nurses. In this article, the epidemiology and mechanism of injury most often observed in patients with blunt chest trauma are reviewed. Selected pulmonary injuries are discussed in terms of mechanism of injuries, assessment and diagnostic modalities, standard therapies, and cutting-edge therapies used today with a focus on pulmonary contusion. Many advances and experimental therapies currently used in the management of the patient with severe lung injuries are discussed. A case study is presented highlighting a complicated case of a blunt chest injury resulting in severe pulmonary contusion.
