Lung contusion

BACKGROUND: Thoracic surgery without general anesthesia can be traced back to the First World War, and thoracic epidural block was used to complete the operation due to a large number of patients with gunshot wounds who needed emergency thoracic surgery. By reducing the intraoperative opioid dose, intraoperative and postoperative opioid-related adverse events such as respiratory depression, nausea and vomiting, delirium, hyperalgesia, and other side effects can be reduced to the benefit of patients...

A 47-year-old male patient was referred to a level 1 trauma center with refractory acute respiratory distress syndrome, bilateral lung contusions, and flail chest after initial management for injuries sustained 5 days prior from an 8-m fall from a tower crane. Surgical stabilization of the rib fractures was achieved under extracorporeal membrane oxygenation support, with successful decannulation 4 days after surgery. The patient was discharged after 42 days and following multidisciplinary interventions...

Page kidney is a condition where external compression of the renal artery and renal parenchyma leads to subsequent ischaemia and activation of renin-angiotensin-aldosterone axis. A 42-year-old female with hirsutism, hypertension and diabetes was diagnosed with a right adrenal mass and underwent laparoscopic adrenalectomy. Her hypertension worsened postoperatively and was managed medically. Subsequently she developed a right flank pain on the fifth postoperative day and died suddenly the next day. Autopsy revealed a pale body with cushingoid appearance...

AIM: Organ tissue damage, including the lungs, may lead to acute coagulopathy. This study aimed to evaluate the association between lung contusion volume and serum fibrinogen level during the acute phase of trauma. METHODS: We conducted an observational study using electronic medical records at a tertiary-care center between January 2015 and December 2018. We included patients with lung contusions on hospital arrival. We used three-dimensional computed tomography to calculate lung contusion volumes...

BACKGROUND: Previous preclinical studies have demonstrated sex-specific alterations in the gut microbiome following traumatic injury or sepsis alone; however, the impact of host sex on dysbiosis in the setting of postinjury sepsis acutely is unknown. We hypothesized that multicompartmental injury with subsequent pneumonia would result in host sex-specific dysbiosis. METHODS: Male and proestrus female Sprague-Dawley rats (n = 8/group) were subjected to either polytrauma (PT) (lung contusion, hemorrhagic shock, cecectomy, bifemoral pseudofracture), PT plus 2-hours daily restraint stress (PT/RS), PT with postinjury day 1 pseudomonas aeruginosa pneumonia (PT + PNA), PT/RS with pneumonia (PT/RS + PNA), or naive controls...

Our previous research studies have demonstrated the role of microRNA133b (miR133b) in healing the contused spinal cord when administered either intranasally or intravenously 24 h following an injury. While our data showed beneficial effects of exogenous miR133b delivered within hours of a spinal cord injury (SCI), the kinetics of endogenous miR133b levels in the contused spinal cord and rostral/caudal segments of the injury were not fully investigated. In this study, we examined the miR133b dysregulation in a mouse model of moderate unilateral contusion injury at the fifth cervical (C5) level...

Transarticular external fixation is primarily used for open fractures involving the joint. However, its biggest drawback is the potential forjoint dysfunction. The article reports a successful case with complex open tibial plateau fracture treated using locked plate external fixation technique during bone callus formation stage to replace transarticular external fixation. We present a case of a 55-year-old male who sustained a complex open fracture of the tibial plateau. In addition, he also suffered from multiple rib fractures, a fibula fracture, a clavicle fracture, hemorrhagic shock, and lung contusion...

BACKGROUND: Thoracic trauma is a frequent injury in the routine treatment of injured patients. Due to the increasing demographic changes a further increase is to be expected, especially after low-energy trauma. OBJECTIVE: Expected complications after conservative vs. operative treatment of various injury patterns of thoracic trauma. MATERIAL AND METHODS: Evaluation of a selective literature search regarding possible complications after thoracic trauma and formulation of instructions for action as expert recommendations...

BACKGROUD: Thoracic Trauma and Limb Fractures Are the Two most Common Injuries in Multiple Trauma. However, there Is Still a Lack of Mouse Models of Trauma Combining Tibial Shaft Fracture (TSF) and Thoracic Trauma. In this Study, we Attempted to Develop a Novel Mouse Model of TSF Combined with Blunt Chest Trauma (BCT). METHODS: A total of 84 C57BL/6J male mice were used as the multiple trauma model. BCT was induced by hitting the chests of mice with heavy objects, and TSF was induced by hitting the tibia of mice with heavy objects after intramedullary fixation...

OBJECTIVES: Although rib fractures are a risk factor, not all rib fracture patients will develop delayed hemothorax. This study aimed to evaluate risk factors which can identify rib fracture patients in the emergency department who may develop delayed hemothorax. METHODS: Adult patients seen in the emergency room between January 2016 and February 2021 with rib fractures caused by blunt chest trauma were included in this retrospective observational study. Patients who underwent chest tube insertion within 2 days and those without follow-up chest radiographs within 2-30 days were excluded...

Chest trauma incidence is increasing worldwide, and it requires attention as it is a major cause of morbidity and mortality. Worldwide, chest trauma is the second most common cause of mortality and a major cause of disability and hospitalization. Our main aim is to systematically review the prevalence, pattern, causes, manner, morbidity, and mortality of chest trauma in the Middle East among adults. This scoping review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines...

Modern approaches to intensive care and anesthesiology make it possible to save patients with various severe traumas. Prolonged mechanical ventilation allows stabilizing the patient's status, but can result severe complications including tracheoesophageal fistula. Our patient received severe combined injury after road accident, i.e. compression-comminuted fractures of DIV, DV, DVI vertebrae with spinal cord compression, ThIII compression fracture, compression-comminuted fracture of bodies and arches ThIV, V, VI with ThVI dislocation, lower paraplegia and pelvic organ dysfunction, left-sided laryngeal paresis, brain concussion and contusion of both lungs...

Pulmonary fat embolism (PFE) as a cause of death often occurs in trauma cases such as fractures and soft tissue contusions. Traditional PFE diagnosis relies on subjective methods and special stains like oil red O. This study utilizes computational pathology, combining digital pathology and deep learning algorithms, to precisely quantify fat emboli in whole slide images using conventional hematoxylin-eosin (H&E) staining. The results demonstrate deep learning's ability to identify fat droplet morphology in lung microvessels, achieving an area under the receiver operating characteristic (ROC) curve (AUC) of 0...

BACKGROUND: A significant proportion of patients with severe chest trauma require mechanical ventilation (MV). Early prediction of the duration of MV may influence clinical decisions. We aimed to determine early risk factors for prolonged MV among adults suffering from severe blunt thoracic trauma. METHODS: This retrospective, single-center, cohort study included all patients admitted between January 2014 and December 2020 due to severe blunt chest trauma. The primary outcome was prolonged MV, defined as invasive MV lasting more than 14 days...

OBJECTIVE: The objective of this study is to compare patients with severe and mild blunt thoracic trauma, who survived an earthquake and presented to the emergency department (ED), in order to identify factors influencing the severity of trauma in earthquake-related thoracic injuries. METHODS: This retrospective, cross-sectional, observational comparative study included patients with isolated thoracic injuries due to the February 6th Kahramanmaraş earthquake...

BACKGROUND: An improvised air gun with marble bullets, locally known as "Jolen Gun", is a type of home-made gun using Polyvinyl chloride (PVC) pipes and compressed air. It is mainly being used as a hunting tool in Central Mindanao. This "non-lethal" weapon has the potential in causing serious harm. There has been several incidents of minor injuries from this type of weapon in our institution but this is the first documented case of an improvised marble air-gun causing significant injury to the patient...

Background: Severe trauma and hemorrhagic shock lead to persistent anemia. Although biologic gender is known to modulate inflammatory responses after critical illness, the impact of gender on anemia recovery after injury remains unknown. The aim of this study was to identify gender-specific differences in anemia recovery after critical illness. Materials and Methods: Male and proestrus female Sprague-Dawley rats (n = 8-9 per group) were subjected to lung contusion and hemorrhagic shock (LCHS) or LCHS with daily chronic stress (LCHS/CS) compared with naïve...

INTRODUCTION: Pneumonia is a common complication after severe trauma that is associated with worse outcomes with increased mortality. Critically ill trauma patients also have persistent inflammation and bone marrow dysfunction that manifests as persistent anemia. Terminal erythropoiesis, which occurs in bone marrow structures called erythroblastic islands (EBIs), has been shown to be impacted by trauma. Using a preclinical model of polytrauma and pneumonia, we sought to determine the effect of infection on bone marrow dysfunction and terminal erythropoiesis...

BACKGROUND: Preclinical studies of the gut microbiome after severe traumatic injury have demonstrated severe dysbiosis in males, with sex-specific microbial differences up to 2 days after injury. However, the impact of host sex on injury-driven dysbiosis over time remains unknown. We hypothesized that sex-specific differences in intestinal microbiome diversity and composition after traumatic injury with and without stress would persist after 7 days. METHODS: Male and proestrus female Sprague-Dawley rats (n = 8/group) were subjected to either polytrauma (lung contusion, hemorrhagic shock, cecectomy, bifemoral pseudofractures), polytrauma plus chronic restraint stress, or naïve controls...
