[Severe Thoracic Trauma Indications and Contraindications for Non-operative and Operative Treatment Strategies]. / Das schwere Thoraxtrauma: Indikationen und Kontraindikationen für operative und nicht operative Versorgungsstrategien.

Severe thoracic trauma can occur as a penetrating or blunt mono-injury or as part of a polytrauma. Almost half of all severely injured patients documented in the TraumaRegister DGU were diagnosed with severe chest trauma, defined according to the Abbreviated Injury Scale (AIS) as ≥ 3. In our own collective, the proportion was even higher with 60%. Emergency surgical treatment with a thoracotomy within the Trauma Resuscitation Unit or within the first hour of admission is an extremely rare intervention in Germany, accounting for 0.9% of severe thoracic injuries. The management of complex polytraumas and extensive pathophysiological reactions to the trauma, as well as knowledge about the development of secondary damage have led to the conclusion that minimally invasive procedures such as video-assisted thoracoscopy (VATS) or inserting a chest drain can resolve most severe thoracic injuries. At < 4%, penetrating injuries to the thorax are a rarity. Among blunt thoracic injuries, > 6% show an unstable thoracic wall that requires surgical reconstruction. The demographic development in Germany leads to a shift in injury pattern. Low-energy trauma results have lower incidence than higher-grade chest wall injuries with penetrating rib fractures in the pleura, lungs, peri-/myocardium and diaphragm. Sometimes this results in instability of the chest wall with severe restriction of respiratory mechanics, which leads to fulminant pneumonia and even ARDS (Acute Respiratory Distress Syndrome). With this background, surgical chest wall reconstruction has become increasingly important over the past decade. Together with the underlying strong evidence, the assessment of the extend and severity of the trauma and the degree of respiratory impairment are the basis for a structured decision on a non-surgical or surgical-reconstructive strategy, as well as the timing, type and extent of surgery. Early surgery within 72 hours can reduce morbidity (pneumonia rate, duration of intensive care and ventilation) and mortality. In the following article, evidence-based algorithms for surgical and non-operative strategies are discussed in the context on the management of severe thoracic injuries. Thus, a selective literature search was carried out for the leading publications on indications, treatment strategy and therapy recommendations for severe thoracic injury, chest wall reconstruction.

[Penetrating Lung Injury Complicated by Hemodynamic Cerebral Infarction].

We encountered a case in which emergency surgery was performed for a penetrating lung injury complicated by a hemodynamic cerebral infarction. A 45-year-old man sustained a chest injury due to a scattered piece of metal and was admitted to a nearby hospital. He was confirmed to have hemorrhagic shock due to a right hemopneumothorax, and a chest tube was inserted he was transferred to our hospital. Chest radiography and computed tomography (CT) revealed a metal fragment in the right lung and confirmed the diagnosis of a penetrating lung injury due to a foreign body. The patient also presented with total blindness of an unknown etiology. Emergency surgery was performed to treat the injury and remove the foreign body. A large amount of blood and hematoma were removed from the right thoracic cavity, and a metal fragment was found in the lower lobe of the right lung. After removing the foreign body, pulmonary suturing was performed. On the following day, head magnetic resonance imaging revealed multiple cerebral infarctions in the bilateral occipital lobes, left frontal lobe, and left cerebellar hemisphere. However, no vascular occlusion or thrombus was found, and the patient was diagnosed with hemodynamic cerebral infarction due to hemorrhagic shock.

Forensic medical evaluation of penetrating abdominal injuries.

BACKGROUND: This study aims to discuss the characteristics, origins, degree of injury, results, reporting, and forensic medical aspects of penetrating abdominal injuries. METHODS: In this study, 28,619 cases who applied to the emergency department of Kutahya Health Sciences University Evliya Celebi Training and Research Hospital between January 1, 2016 and December 31, 2020 were reviewed. The forensic reports and medical documents of 85 cases with penetrating abdominal injuries were evaluated retrospectively, with the approval of the ethics committee. RESULTS: Among the patients included in the study, 87.1% were male and 12.9% were female. The mean age was found to be 31±13 years. When the origins of the cases were analyzed, 87.1% were found to have developed as a result of intentional injury. The incidents predominantly occurred between 20: 00 and 04: 00 hours. As a result of the examinations performed at the hospital after the incident, alcohol was detected in 36.5% of the cases, while 30.6% of the individuals did not consume alcohol. It was observed that 32.9% of the cases were not tested for alcohol. The most common injuries identified were sharp injuries, accounting for 69.4% of cases, and firearm injuries, comprising 27.1%. Organ damage was noted in 68.2% of the cases, with the small intestine being the most frequently damaged organ. The average number of wounds present was 3.6. Intra-abdominal hemorrhage was detected in 61.2% of the cases, and intra-abdominal artery injuries were found in 8.2%. The mortality rate for penetrating abdominal injuries was 8.2%. CONCLUSION: In forensic traumatology, penetrating abdominal injuries commonly lead to life-threatening conditions and loss of organ function, which represent the most severe category in trauma severity assessment. Penetrating abdominal injuries most often result from violent incidents, as observed in our study and in the literature.

Manejo cirúrgico de ferimento auto-infligido por arma de fogo em região maxilofacial / Surgical management of self-inflicted injury by gun in the maxillofacial region

INTRODUÇÃO: O manejo dos pacientes vítimas de PAF possui vertentes divergentes a respeito do tratamento cirúrgico, que pode ser realizado de forma imedata ou tardia. Em lesões auto-infligidas, a distância entre a arma e a região acometida é menor, causando consequências estéticas e funcionais mais devastadoras. Aliado ao fato desse tipo de trauma criar uma ferida suja devido à comunicação com a cavidade oral e seios paranasais, o manejo das lesões representam um desafio mesmo à cirurgiões experientes. OBJETIVO: Estre trabalho relata o manejo cirúrgico de uma ferida auto-infligida por arma de fogo que resultou em avulsão dos tecidos moles na região maxilofacial. DESCRIÇÃO DO CASO: Paciente do sexo masculino, 35 anos, vítima de projétil de arma de fogo auto-infligido em região maxilofacial, cursando com extenso ferimento em região de língua e mento. Clinicamente, o paciente não apresentava sinais de fratura em ossos da face. Ambos os ferimentos apresentavam secreção purulenta e o paciente manifestava disfonia devido a grande destruição tecidual. CONSIDERAÇÕES FINAIS: O tratamento de ferimentos por arma de fogo não só é um grande desafio para o cirurgião, como para toda a equipe multidisciplinar requerida para tais casos, visto que não há protocolos bem definidos para o tratamento dessas lesões(AU)

INTRODUCTION: The management of patients who are victims of FAP has divergent aspects regarding surgical treatment, which can be performed immediately or late. In self-inflicted injuries, the distance between the weapon and the affected region is smaller, causing more devastating aesthetic and functional consequences. Allied to the fact that this type of trauma creates a dirty wound due to the communication with the oral cavity and paranasal sinuses, the management of injuries represents a challenge even for experienced surgeons. OBJECTIVE: This paper reports the surgical management of a self-inflicted gunshot wound that resulted in soft tissue avulsion in the maxillofacial region. CASE DESCRIPTION: Male patient, 35 years old, victim of a self-inflicted firearm projectile in the maxillofacial region, coursing with extensive injury in the region of the tongue and chin. Clinically, the patient did not show signs of facial bone fractures. Both wounds had purulent secretion and the patient had dysphonia due to extensive tissue destruction. FINAL CONSIDERATIONS: The treatment of gunshot wounds is not only a great challenge for the surgeon, but also for the entire multidisciplinary team required for such cases, since there are no well-defined protocols for the treatment of these injuries(AU)

Pneumonectomy following penetrating trauma with ECMO as postoperative support: case report - (Lung trauma and ECMO).

BACKGROUND: Penetrating thoracic injuries have a significant risk of morbi-mortality. Despite the advancements in damage control methods, a subset of patients with severe pulmonary vascular lesions and bronchial injuries persists. In some of these cases, post-traumatic pneumonectomy is required, and perioperative extracorporeal membrane oxygenation (ECMO) support may be required due to right ventricular failure and respiratory failure. CASE DESCRIPTION: A male was brought to the emergency department (ED) with a penetrating thoracic injury, presenting with massive right hemothorax and active bleeding that required ligation of the right pulmonary hilum to control the bleeding. Subsequently, he developed right ventricular dysfunction and ARDS, necessitating a dynamic hybrid ECMO configuration to support his condition and facilitate recovery. CONCLUSIONS: Penetrating thoracic injuries with severe pulmonary vascular lesions may need pneumonectomy to control bleeding. ECMO support reduces the associated mortality by decreasing the complications rate. A multidisciplinary team is essential to achieve good outcomes in severe compromised patients.

Endovascular treatment for 2 types of subclavian artery injury: A case report.

RATIONALE: Subclavian artery (SCA) injuries, though rare, carry significant morbidity and mortality risks due to significant blood loss causing hypovolemic shock. Early diagnosis and adequate treatment are crucial to minimize bleeding and associated morbidity. Recent advances in endovascular techniques offer faster and more accurate treatment options compared to traditional open surgical repair. This study demonstrates the efficacy of endovascular treatment in 2 cases of SCA injury and reviews its indications, limitations, and precautions. PATIENT CONCERNS: A 69-year-old man presented with a penetrating SCA injury from a steel bar, and a 38-year-old woman presented with a blunt SCA injury caused by a fall. Both patients were hemodynamically unstable upon presentation. DIAGNOSES: Both patients were diagnosed with SCA injuries. The man had a penetrating injury, while the woman had a blunt injury, both resulting in hemodynamic instability and significant risk of hypovolemic shock. INTERVENTIONS: Endovascular techniques, including the use of covered stent grafts, were employed to manage the injuries. These techniques allowed for rapid and efficient treatment, reducing the need for open surgical intervention. OUTCOMES: Both patients were successfully treated using endovascular methods and were discharged without any complications. The endovascular approach minimized blood loss, transfusion needs, and hospital stay. LESSONS: This study demonstrates the effectiveness of endovascular techniques in rapidly diagnosing, bridging, and definitively treating SCA injuries, suggesting their use as a first-line therapy.

Outcomes and Its Associated Factors among Patients with Abdominal Trauma Requiring Laparotomy at Asella Referral and Teaching Hospital, South Central Ethiopia: A Retrospective Cross-Sectional Study.

Trauma is a serious public health problem, and abdominal injuries are among the leading causes of hospitalization after trauma. Therefore, this study aimed to determine the outcome of abdominal trauma and its predictors in patients who underwent laparotomy at Asella Referral and Teaching Hospital (ARTH), South Central Ethiopia. We conducted a retrospective institutional based cross-sectional study of patients who underwent laparotomy for abdominal trauma at ARTH from October 1, 2015, to September 30, 2020. Bivariate and multivariate logistic regressions were used to determine associations between independent factors and mortality due to abdominal trauma, and a P value of <0.05 indicated statistical significance. Out of 139 patients, 110 (79.1%) were males and 88 (63.3%) aged <30 years old, with a mean age of 29 ± 15.73 years. The most common mechanism of injury was penetrating trauma, which accounted for 94 (67.6%) patients. The mortality rate was 21 (15.1%). Factors such as blunt mechanism of injury (95% CI: AOR: 3.36, 1.24-9.09), SBP < 90 mmHg at presentation (95% CI: AOR = 9.37, 3.28-26.80), time >6 hours from trauma to admission (95% CI: AOR: 5.44, 1.78-16.63), unstable intraoperative patient condition (95% CI: AOR = 8.82, 3.05-25.52), and patients who need blood transfusion (95% CI: AOR: 6.63, 1.92-22.91) were significantly associated with mortality. The mortality rate of abdominal trauma patients who underwent laparotomy was high. Therefore, healthcare providers should provide priority for traumatic patients as prolonged waiting time to get healthcare results in poor outcomes for the patients.

Characteristics of blunt and penetrating trauma among victims of physical violence: A retrospective study.

BACKGROUND: A significant number of referrals to the emergency departments is due to violence and conflict leading to serious injuries and death. The increasing number of such cases highlights the urgent need for investigating victimization of physical violence. AIM: The purpose of this study was to determine the frequency of demographic and clinical characteristics in victims of violence and classify them based on penetrating or blunt trauma. METHODS: The data of the patients who had been the victims of violence in 2020 were extracted from the Trauma Registry System(TRS) of the Guilan Road Trauma Research Center(GTRC). All analyses were performed using SPSS software version 24. The significance level was considered less than 0.05. RESULTS: There was a significant difference in the type of violence-related trauma in different age groups (P < 0.001), based on sex (P = 0.002), and marital status (P = 0.012). A significant difference also existed between the trauma type and clinical variables including smoking (P = 0.032), history of alcohol drinking (P = 0.005), and other substance use (P = 0.002), the anatomical location of injury (P < 0.001) and therapeutic interventions (p < 0.001(. CONCLUSION: Most of the clients of the violence suffered from blunt trauma, the severity of which was mild, and they were treated supportively without the need for surgery. Blunt trauma was seen more in women, divorcees, over 40 years and non-smokers. Penetrating trauma was observed more in lower limb injuries and alcohol and amphetamine users. Prevention programs and educational interventions should be programmed for the society long before men alcohol and amphetamine abusers reach their fourth decade of life. Accurately recording the type of physical violence, and the weapon used, and determining the injury severity score in TRS can lead to more reliable results in researching the field of violence issues.

Right ventricle pierced by a traditional sharp hair straightener: a case report.

The case presents a traumatic ventricular perforation of a girl, accidentally felt on a sharp instrument. The uniqueness of the case presented is due to the very high infrequency of injuries with this type of sharp object. The 7-year-old girl was transported to the hospital after accidentally falling on a sharp instrument. The child had no signs of heart failure. On opening the chest, it was found that the metal object was lodged in the right ventricle. Quickly proceeded to remove the object and suture the entry hole. After a short hospitalization, the child was discharged completely cured.

Outcomes of penetrating carotid artery injuries: A South African multicentre study.

BACKGROUND: This multicenter study examines the contemporary management of penetrating carotid artery injury (PCAI) to identify trends in management, outcomes, and to determine prognostic factors for stroke and death. METHODS: Data from three large urban trauma centers in South Africa were retrospectively reviewed for patients who presented with PCAI from 2012 to 2020. RESULTS: Of 149 identified patients, 137 actively managed patients were included. Twenty-four patients (17.9%) presented in coma and 12 (9.0%) with localizing signs (LS). CT angiography was performed on admission for 120 (87.6%) patients. Thirty patients (21.9%) underwent nonoperative management, 87 (63.5%) open surgery, and 20 (14.6%) endovascular stenting. Eighteen patients (13.1%) died, and 15 (12.6%) surviving patients had strokes. Ligation was significantly related to death and reperfusion to survival. A mechanism of gunshot wound, occlusive injuries, a threatened airway, a systolic blood pressure <90 mmHg, hard signs of vascular injury, a low GCS, coma, a CT brain demonstrating infarct, a high injury severity score and shock index, a low pH or HCO3, and an elevated lactate were significant independent prognostic factors for death. Ligation was unsurvivable in all patients with severe neurological deficits, whereas reperfusion procedures resulted in survival in 63% (12/19) patients with coma and 78% (7/9) with LS although with high stroke rates (coma: 25.0%, LS: 85.7%). CONCLUSIONS: Outcomes in PCAI, including patients with severe neurological deficit and stroke, are better when reperfused. Reperfusion holds the best promise of survival and ligation should be reserved for technically inaccessible bleeding injuries.

Evaluating the Shock Index, Revised Assessment of Bleeding and Transfusion (RABT), Assessment of Blood Consumption (ABC) and novel PTTrauma score to predict critical transfusion threshold (CAT) in penetrating thoracic trauma.

The shock index (SI) has been associated with predicting transfusion needs in trauma patients. However, its utility in penetrating thoracic trauma (PTTrauma) for predicting the Critical Administration Threshold (CAT) has not been well-studied. This study aimed to evaluate the prognostic value of SI in predicting CAT in PTTrauma patients and compare its performance with the Assessment of Blood Consumption (ABC) and Revised Assessment of Bleeding and Transfusion (RABT) scores. We conducted a prognostic type 2, single-center retrospective observational cohort study on patients with PTTrauma and an Injury Severity Score (ISS) > 9. The primary exposure was SI at admission, and the primary outcome was CAT. Logistic regression and decision curve analysis were used to assess the predictive performance of SI and the PTTrauma score, a novel model incorporating clinical variables. Of the 620 participants, 53 (8.5%) had more than one CAT. An SI > 0.9 was associated with CAT (adjusted OR 4.89, 95% CI 1.64-14.60). The PTTrauma score outperformed SI, ABC, and RABT scores in predicting CAT (AUC 0.867, 95% CI 0.826-0.908). SI is a valuable predictor of CAT in PTTrauma patients. The novel PTTrauma score demonstrates superior performance compared to existing scores, highlighting the importance of developing targeted predictive models for specific injury patterns. These findings can guide clinical decision-making and resource allocation in the management of PTTrauma.

Focused assessment with sonography for trauma exam for diagnosis of pericardial effusion in penetrating thoracic trauma - A retrospective review from a level 1 trauma center.

INTRODUCTION: Point of care ultrasound has long been used in the trauma setting for rapid assessment and diagnosis of critically ill patients. Its utility for diagnosis of pericardial effusion in the setting of penetrating thoracic trauma has more recently been a topic of consideration, given the rapid decompensation that these patients can experience. OBJECTIVES: This study aims to identify the diagnostic accuracy of point of care ultrasound in the diagnosis of pericardial effusion among patients with penetrating thoracic trauma. METHODS: Retrospective review of 2099 patients brought to the trauma bay between the years 2016 and 2021 were analyzed for diagnosis of pericardial effusion. Patients who were diagnosed with a pericardial effusion were investigated for point of care ultrasound findings. Descriptive statistics were performed to identify sensitivity, specificity, positive predictive value, and negative predictive value. RESULTS: Prevalence was calculated to be 26.7 cases of pericardial effusion per 1000 patients presenting with penetrating thoracic trauma. Incidence was estimated to be 3.8 cases of pericardial effusion per 1000 person-years. Calculation of diagnostic capabilities of ED POCUS revealed a sensitivity of 96.36 â€‹%, a specificity of 100 â€‹%, PPV of 100 â€‹%, and NPV of 99.90 â€‹%. CONCLUSIONS: Point of Care cardiac ultrasonography is a reliable tool for the rapid diagnosis of pericardial effusion in penetrating thoracic trauma patients. Patients with ultrasound suggestive of this condition should receive rapid surgical management to prevent decompensation.

[Initial in-hospital treatment of patients with penetrating trauma due to violence and war]. / Innerklinische Erstversorgung von Patienten mit penetrierendem Trauma nach Gewalt und Krieg.

BACKGROUND: Current political and social developments have brought the topics of violence, in this context attributable to terrorism and sabotage, and since February 2022 awareness of war in particular has again greatly increased. This article aims to present the contextualized dealing with penetrating injuries in terms of initial in-hospital treatment. OBJECTIVE: The question remains to be answered as to what extent penetrating injuries require special attention and to what extent the treatment priorities, options and strategies as well as surgical treatment require adaptation of the usual approach in routine clinical practice in Germany. MATERIAL AND METHOD: The experience of the authors in this field from military operations in Afghanistan, Iraq, the Republic of Mali, Kosovo and Georgia as well as the core content of the Terror and Disaster Surgical Care (TDSC®) course on this topic, have been contextualized and incorporated. In addition, aspects of a comprehensive systematic literature review and current data from a national evaluation on the topic of preparing hospitals in Germany for such scenarios are taken into account. RESULTS AND DISCUSSION: The clinical systems need to be well-prepared for such casualties, especially if they require treatment in large numbers. This is precisely so because the majority of patients are in a relevantly threatening situation (usually in the sense of a hemorrhage), treatment must be very urgently provided and in such scenarios a lack of resources must always be overcome, at least temporarily, especially for example for blood transfusions.

Cost-effectiveness analysis of routine computed tomography angiography (CTA) for lower extremity penetrating trauma.

BACKGROUND: Routine evaluation with CTA for patients with isolated lower extremity penetrating trauma and normal ankle-brachial-indices (ABI) remains controversial. While prior literature has found normal ABI's (≥0.9) and a normal clinical examination to be adequate for safe discharge, there remains concern for missed injuries which could lead to delayed surgical intervention and unnecessary morbidity. Our hypothesis was that routine CTA after isolated lower extremity penetrating trauma with normal ABIs and clinical examination is not cost-effective. METHODS: We performed a decision-analytic model to evaluate the cost-effectiveness of obtaining a CTA routinely compared to clinical observation and ABI evaluation in hemodynamically normal patients with isolated penetrating lower extremity trauma. Our base case was a patient that sustained penetrating lower extremity trauma with normal ABIs that received a CTA in the trauma bay. Costs, probability, and Quality-Adjusted Life Years (QALYs) were generated from published literature. RESULTS: Clinical evaluation only (no CTA) was cost-effective with a cost of $2056.13 and 0.98 QALYs gained compared to routine CTA which had increased costs of $7449.91 and lower QALYs 0.92. Using one-way sensitivity analysis, routine CTA does not become the cost-effective strategy until the cost of a missed injury reaches $210,075.83. CONCLUSIONS: Patients with isolated, penetrating lower extremity trauma with normal ABIs and clinical examination do not warrant routine CTA as there is no benefit with increased costs.

Epidemiological profile of patients undergoing non-operative management of solid organ injury and associated factors with mortality.

INTRODUCTION: Trauma primarily affects the economically active population, causing social and economic impact. The non-operative management of solid organ injuries aims to preserve organ function, reducing the morbidity and mortality associated with surgical interventions. The aim of study was to demonstrate the epidemiological profile of patients undergoing non-operative management in a trauma hospital and to evaluate factors associated with mortality in these patients. METHODS: This is a historical cohort of patients undergoing non-operative management for solid organ injuries at a Brazilian trauma reference hospital between 2018 and 2022. Included were patients with blunt and penetrating trauma, analyzing epidemiological characteristics, blood transfusion, and association with the need for surgical intervention. RESULTS: A total of 365 patients were included in the study. Three hundred and forty-three patients were discharged (93.97%), and the success rate of non-operative treatment was 84.6%. There was an association between mortality and the following associated injuries: hemothorax, sternal fracture, aortic dissection, and traumatic brain injury. There was an association between the need for transfusion and surgical intervention. Thirty-eight patients required some form of surgical intervention. CONCLUSION: The profile of patients undergoing non-operative treatment consists of young men who are victims of blunt trauma. Non-operative treatment is safe and has a high success rate.
