BACKGROUND: Patients sustaining pulmonary contusion (PC) have a higher risk of complications and long-term respiratory difficulty. Computed tomography (CT) scans have a high sensitivity for PC. However, since PC develops over time, CT scans made directly post-trauma may underestimate the full extent of PC. This creates a need to better define in which PC-patients complications are more likely. The aim of this systematic review was to identify different classification systems of PC, and investigate the association between amount of PC and in-hospital outcomes.
METHODS: A systematic review was conducted in accordance with PRISMA guidelines. Studies reporting a classification system for PC after blunt thoracic trauma based on a CT scan were included. Outcomes were classification method of PC and the relation between classification and pulmonary complications and in-hospital outcomes.
RESULTS: Twenty studies were included. Total number of patients ranged from 49 to 148,140 patients. The most common classification system used was calculating the percentage of contused lung volume. Other classification methods were based on Blunt Pulmonary Contusion score-6 and -18, Abbreviated Injury Score and Thoracic Trauma Severity scores. Worse outcomes were generally associated with between > 18 to > 24% contusion volume.
CONCLUSIONS: The heterogeneity of currently available literature makes comparing classification methods challenging. The most common classification of PC was based on volumetric analysis. Calculating a percentage of PC as part of the total volume allows for the highest level of segmentation of lung parenchyma as compared to using BPC-6, BPC-18, or AIS. Contusion volume exceeding 18-24% was generally associated with worse outcomes.

Traumatic main bronchus rupture is a relatively rare injury in thoracic trauma, which is extremely critical, with a mortality rate as high as 70% - 80%. The complete rupture and displacement of the traumatic cervical trachea can lead to asphyxia, hypoxia, and cardiac arrest, even death of the patient in a short time. We performed emergency surgery with the support of extracorporeal membrane oxygenation for a case of traumatic cervical tracheal trunk complete rupture and displacement combined with cardiac arrest and achieved a successful rescue. We summarized our experience and found that timely surgical reconstruction of the airway is the key to increasing the traumatic main bronchus rupture survival of patients.

OBJECTIVE: Our understanding of the growing geriatric population\'s risk factors for outcomes after traumatic injury remains incomplete. This study aims to compare outcomes of severe isolated blunt chest trauma between young and geriatric patients and assess predictors of mortality.
METHODS: The ACS-TQIP 2017-2020 database was used to identify patients with severe isolated blunt chest trauma. Patients having extra-thoracic injuries, no signs of life upon presentation to the emergency department (ED), prehospital cardiac arrest, or who were transferred to or from other hospitals were excluded. The primary outcome was in-hospital mortality. Univariate and multivariable regression analyses were performed to assess independent predictors of mortality.
RESULTS: A total of 189,660 patients were included in the study, with a median age of 58 years; 37.5% were aged 65 or older, and 1.9% died by discharge. Patients aged 65 and older had significantly higher mortality (3.4% vs. 1.0%, p < 0.001) and overall complications (7.0% vs. 4.7%, p < 0.001) compared to younger patients. Age ≥ 65 was independently associated with mortality (OR: 5.45, 95%CI: 4.96-5.98, p < 0.001), prolonged hospitalization, and complications. In the geriatric group, age > 75 was an independent predictor of mortality compared to ages 65-75 (OR: 2.62, 95%CI: 2.37-2.89, p < 0.001). Geriatric patients with an MVC, presenting with a GCS ≤ 8, and having an SBP < 90 had the highest mortality of 56.9%.
CONCLUSIONS: The geriatric trauma patient with isolated severe blunt chest injury has significantly higher mortality and morbidity compared to younger patients and warrants special consideration of multiple factors that affect outcomes. Individual predictors of mortality carry a greater impact on mortality in geriatric patients.

OBJECTIVE: Emergency resuscitative thoracotomy (ERT) has been described as a potentially life-saving procedure for trauma patients who have been admitted in refractory shock or with recent loss of sign of life (SOL). This nationwide registry analysis aimed to describe the French practice of ERT.
METHODS: From 2015 to 2021, all severe trauma patients who underwent ERT were extracted from the TraumaBase→ registry. Demographic data, prehospital management and in-hospital outcomes were recorded to evaluate predictors of success-to rescue after ERT at 24-hour and 28-day.
RESULTS: Only 10/26 Trauma centers have an effective practice of ERT, three of them perform more than 1 ERT/year. Sixty-six patients (74% male, 49/66) with a median age of 37 y/o [26-51], mostly with blunt trauma (52%, 35/66) were managed with ERT. The median pre-hospital time was 64mins [45-89]. At admission, the median injury severity score was 35 [25-48], and 51% (16/30) of patients have lost SOL. ERT was associated with a massive transfusion protocol including 8 RBCs [6-13], 6 FFPs [4-10], and 0 PCs [0-1] in the first 6h. The overall success-to-rescue after ERT at 24-h and 28-d were 27% and 15%, respectively. In case of refractory shock after penetrating trauma, survival was 64% at 24-hours and 47% at 28-days.
CONCLUSIONS: ERT integrated into the trauma protocol remains a life-saving procedure that appears to be underutilized in France, despite significant success-to-rescue observed by trained teams for selected patients.

A 31-year-old male sustained life-threatening chest contusions and recovered after damage control surgery. The patient was in an unwitnessed accident where his motorcycle was struck by a car. Upon admission, blood pressure was 69/58 mmHg, heart rate was 126 bpm, and oxygen saturation was 85%. Chest computed tomography revealed fractures to right ribs 1-9 and left ribs 1-7, lung contusions, multiple lung lacerations, and right hemopneumothorax. Upon presentation to the intensive care unit, hemostasis was achieved by suturing a deeply lacerated lung and applying gauze packing. The patient was placed on veno-veno type extracorporeal membrane oxygenation using both femoral veins after surgery until the 5th hospital day. The gauze was removed during the second operation on the 6th day. The third operation on the 13th hospital day was an open reduction of ribs 3-7 on the right. The patient was discharged on the 47th day without complications.

OBJECTIVE: Chest trauma is a severe and frequent cause of admission to the emergency department (ED). The serratus anterior plane (SAP) block seems to be an effective method of pain management; however, data on efficacy and safety of a single SAP block performed in the ED by emergency physicians (EP) are limited. This study aimed to compare SAP block performed by the EP in the ED plus standard therapy to standard therapy alone in terms of pain severity at 0-3-6-12-18 and 24 h, total opioid consumption (milligrams of morphine equivalents, MME), respiratory function (SpO2/FiO2 ratio), and adverse events (i.e. pneumothorax, infections in the site of injection, or Local Anaesthetic Systemic Toxicity syndrome due to SAP block) in the first 24 h.
METHODS: This retrospective, monocentric study included adult patients admitted to the Sub-intensive Care Unit (SICU) of the ED with multiple rib fractures between 01/2022 and 03/2023.
RESULTS: 156 patients (65.4% male; median age 62 years; median injury severity score 16; median thoracic trauma severity score 8) were included. 75 (48.2%) underwent SAP block. Patients undergoing SAP block showed significantly less pain 3-6-18 h after a single block, required less MME (0 [0-20] vs. 20 [0-40], p < 0.001), showed higher SpO2/FiO2 ratio, and no adverse events were reported.
CONCLUSIONS: The SAP block, in combination with standard therapy, appeared to be more effective in providing pain relief than standard therapy alone in patients admitted to the SICU for traumatic rib fractures.

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.

Objectives: To investigate the diagnostic value of fibrinogen (FIB) in patients with rib fractures complicated by lower extremity deep venous thrombosis (DVT).Methods: Analyzing data from 493 patients at Shijiazhuang Third Hospital, FIB levels at 24, 48, and 72 h post-injury were compared between DVT and non-DVT groups.Results: DVT group had elevated FIB levels at all times (p < .001). FIB at 24 h showed highest AUC, particularly in patients with BMI <28.Conclusion: In conclusion, measuring FIB at 24 h post-injury enhances DVT detection in rib fracture patients, with potential BMI-related variations.

Severe chest trauma often requires immediate intervention, typically involving open chest surgery. However, advancements in medical technology offer alternative approaches, such as endovascular therapy and venovenous extracorporeal membrane oxygenation (VV-ECMO). In a recent case, a middle-aged male cyclist was admitted after colliding with a vehicle, presenting in shock with multiple injuries, including cerebral contusion and rib fractures. Despite initial treatments such as chest tubes and blood transfusions, his condition remained unstable, with worsening respiratory failure and hemorrhagic shock. A multidisciplinary team devised a comprehensive treatment plan, utilizing VV-ECMO for oxygenation support, a bronchial blocker to localize the hematoma, and interventional radiology for hemothorax hemostasis. These interventions successfully stabilized the patient without resorting to open chest surgery. Endovascular therapy, alongside bronchial blockers, facilitated adequate hemostasis and hematoma localization, avoiding invasive procedures. VV-ECMO plays a crucial role in maintaining oxygenation during respiratory failure. Strategic anticoagulation with nafamostat mesylate prevented clotting in the ECMO circuit. This case highlights the effectiveness of minimally invasive strategies in managing severe chest trauma, preserving lung function, and improving outcomes. In refractory cases, VV-ECMO acts as a bridge to stabilize respiratory status before definitive treatment, while bronchial blockers localize hematomas, reducing the need for surgery. Interventional radiology offers a less invasive option for achieving hemostasis. Collaboration among medical specialties and innovative technologies is critical to successfully navigating complex chest trauma cases.

BACKGROUND: Blunt chest injuries result in up to 10 % of major trauma admissions. Comorbidities can complicate recovery and increase the mortality rate in this patient cohort. A better understanding of the association between comorbidities and patient outcomes will facilitate enhanced models of care for particularly vulnerable groups of patients, such as older adults.
OBJECTIVE: i) compare the characteristics of severely injured patients with blunt chest injury with and without comorbidities and ii) examine the relationship between comorbidities and key patient outcomes: prolonged length of stay, re-admission within 28 days, and mortality within 30 days in a cohort of patients with blunt chest injury admitted after severe trauma.
METHODS: A retrospective cohort study using linked data from the NSW Trauma Registry and NSW mortality and hospitalisation records between 1st of January 2012 and 31st of December 2019.
RESULTS: After adjusting for potential confounding factors, patients with severe injuries, chest injuries, and comorbidities were found to have a 34 % increased likelihood of having a prolonged length of stay (OR = 1.34, 95 %I = 1.17-1.53) compared to patients with no comorbidities. There was no difference in 30-day mortality for patients with a severe chest injury who did or did not have comorbidities (OR = 1.05, 95 %CI = 0.80-1.39). No significant association was found between comorbidities and re-admission within 28 days.
CONCLUSIONS: Severely injured patients with blunt chest injury and comorbidities are at risk of prolonged length of stay.
