Thoracic injuries in trauma patients: epidemiology and its influence on mortality

BACKGROUND

Thoracic injuries are common among trauma patients. Studies on trauma patients with thoracic injuries have reported considerable differences in morbidity and mortality, and there is limited research on comparison between trauma patients with and without thoracic injuries, particularly in the Scandinavian population. Thoracic injuries in trauma patients should be identified early and need special attention since the differences in injury patterns among patient population are important as they entail different treatment regimens and influence patient outcomes. The aim of the study was to describe the epidemiology of trauma patients with and without thoracic injuries and its influence on 30-day mortality.

METHODS

Patients were identified through the Karolinska Trauma Register. The Abbreviated Injury Scale (AIS) system was used to find patients with thoracic injuries. Logistic regression analysis was performed to evaluate factors [age, gender, ASA class, GCS (Glasgow Coma Scale), NISS (New Injury Severity Score) and thoracic injury] associated with 30-day mortality.

RESULTS

A total of 2397 patients were included. Of those, 768 patients (32%) had a thoracic injury. The mean (± SD, range) age of all patients (n = 2397) was 46 (20, 18-98) years, and the majority (n = 1709, 71%) of the patients were males. There was a greater proportion of patients with rib fractures among older (≥ 60 years) patients, whereas younger patients had a higher proportion of injuries to the internal thoracic organs. The 30-day mortality was 11% (n = 87) in patients with thoracic injury and 4.3% (n = 71) in patients without. After multivariable adjustment, a thoracic injury was found to be associated with an increased risk of 30-day mortality (OR 1.9, 95% CI 1.3-3.0); as was age ≥ 60 years (OR 3.7, 95% CI 2.3-6.0), ASA class 3-4 (OR 2.3, 95% CI 1.4-3.6), GCS 1-8 (OR 21, 95% CI 13-33) and NISS > 15 (OR 4.2, 2.4-7.3).

CONCLUSION

Thoracic injury was an independent predictor of 30-day mortality after adjustment for relevant key variables. We also found a difference in injury patterns with older patients having a higher proportion of rib fractures, whilst younger patients suffered more internal thoracic organ injuries.

Chest trauma epidemiology and emergency department management in a tertiary teaching hospital in Kigali, Rwanda

Introduction

Chest trauma is a major contributor to injury morbidity and mortality, and understanding trends is a crucial part of addressing this burden in low- and middle-income countries. This study reports the characteristics and emergency department (ED) management of chest trauma patients presenting to Rwanda's national teaching hospital in Kigali.

Methods

This descriptive analysis included a convenience sample of patients presenting to a single tertiary hospital ED with chest trauma from June to December 2017. Demographic data were collected as well as injury mechanism, thoracic and associated injuries, types of imaging obtained, and treatments performed. Chart review was conducted seven days post-admission to follow up on outcomes and additional diagnoses and interventions. Incidences were calculated with Microsoft Excel.

Results

Among the 62 patients included in this study, 74% were male, and mean age was 35 years. Most patients were injured in road traffic crashes (RTCs) (68%). Common chest injuries included lung contusions (79% of cases), rib fractures (44%), and pneumothoraces (37%). Head trauma was a frequent concurrent extra-thoracic injury (61%). Diagnostic imaging primarily included E-FAST ultrasound (92%) and chest x-ray (98%). The most common therapies included painkillers (100%), intravenous fluids (89%), and non-invasive oxygen (63%), while 29% underwent invasive intervention in the form of thoracostomy. The majority of patients were admitted (81%). Pneumonia was the most common complication to occur in the first seven days (32% of admitted patients). Ultimately, 40% of patients were discharged home within seven days of presentation, 50% remained hospitalized, and 5% died.

Conclusion

This study on the epidemiology of chest trauma in Rwanda can guide injury prevention and medical training priorities. Efforts should target prevention in young males and those involved in RTCs. ED physicians in Rwanda need to be prepared to diagnose and treat a variety of chest injuries with invasive and noninvasive means.

Traumatic diaphragmatic rupture: epidemiology, associated injuries, and outcome-an analysis based on the TraumaRegister DGU®

INTRODUCTION

Traumatic diaphragmatic rupture is a rare injury in the severely injured patient and is most commonly caused by blunt mechanisms. However, penetrating mechanisms can also dominate depending on regional and local factors. Traumatic diaphragmatic rupture is difficult to diagnose and can be missed by primary diagnostic procedures in the resuscitation room. Initially not life-threatening, diaphragmatic ruptures can cause severe sequelae in the patient's long-term course if untreated. The objective of this study was to assess the epidemiology, associated injuries, and outcome of traumatic diaphragmatic ruptures based on a multicenter registry-based analysis.

MATERIAL AND METHODS

Data from all patients enrolled in the TraumaRegister DGU® between 2009 and 2018 were retrospectively analyzed. That multicenter database collects data on prehospital, intra-hospital emergency, intensive care therapy, and discharge. Included were all patients with a Maximum Abbreviated Injury Scale (MAIS) score of 3 or above and patients with a MAIS score of 2 who died or were treated in the intensive care unit, for whom standard documentation forms had been completed and who had sustained a diaphragmatic rupture (AIS score of 3 or 4). The data has been analyzed using descriptive statistics and chi-square test or Mann-Whitney U test.

RESULTS

Of the 199,933 patients included in the study population, 687 patients (0.3%) had a diaphragmatic rupture. Of these, 71.9% were male. The mean patient age was 46.1 years. Blunt trauma accounted for 73.5% of the injuries. Primary diagnosis was established in the resuscitation room in 93.1% of the patients. Multislice helical computed tomography (MSCT) was performed in 82.7% of the cases. Rib fractures were detected in 60.7% of the patients with a diaphragmatic injury. Patients with diaphragmatic rupture had a higher mean Injury Severity Score (ISS) than patients without a diaphragmatic injury (32.9 vs. 18.6) and a higher mortality rate (13.2% vs. 9.0%).

CONCLUSIONS

In contrast to the literature, primary diagnostic procedures in the resuscitation room detected relevant diaphragmatic ruptures (AIS ≥ 3) in more than 90% of the patients in our study population. In addition, complex associated serial rib fractures are an important diagnostic indicator.

Outcomes of the resuscitative and emergency thoracotomy at a Dutch level-one trauma center: are there predictive factors for survival?

PURPOSE

To investigate the 30-day survival rate of resuscitative and emergency thoracotomies in trauma patients. Moreover, factors that positively influence 30-day survival rates were investigated.

METHODS

A retrospective study of patients (> 16 years), between 2008 and 2020, who underwent a resuscitative or emergency thoracotomy at a level-one trauma center in the Netherlands was conducted.

RESULTS

Fifty-six patients underwent a resuscitative (n = 45, 80%) or emergency (n = 11, 20%) thoracotomy. The overall 30-day survival rate was 32% (n = 18), which was 23% after blunt trauma and 72% after penetrating trauma, and which was 18% for the resuscitative thoracotomy and 91% for the emergency thoracotomy. The patients who survived had full neurologic recovery. Factors associated with survival were penetrating trauma (p < 0.001), (any) sign of life (SOL) upon presentation to the hospital (p = 0.005), Glasgow Coma Scale (GCS) of 15 (p < 0.001) and a thoracotomy in the operating room (OR) (p = 0.018). Every resuscitative thoracotomy after blunt trauma and pulseless electrical activity (PEA) or asystole in the pre-hospital phase was futile (0 survivors out of 11 patients), of those patients seven (64%) had concomitant severe neuro-trauma.

CONCLUSION

This study found a 30-day survival rate of 32% for resuscitative and emergency thoracotomies, all with good neurological recovery. Factors associated with survival were related to the trauma mechanism, the thoracotomy indication and response to resuscitation prior to thoracotomy (for instance, if resuscitation enables enough time for safe transport to the operating room, survival chances increase). Resuscitative thoracotomies after blunt trauma in combination with loss of SOL before arrival at the emergency room were in all cases futile, interestingly in nearly all cases due to concomitant neuro-trauma.

Distribution of interstitial cells of Cajal in the Esophagus and change in distribution after thoracic trauma

Interstitial cells of Cajal (ICCs) function as pacemaker cells in the gastrointestinal tract. Acute thoracic trauma is a common and lethal cause of death due to physical trauma caused by traffic accidents. This study aimed to explore the distribution of esophageal ICCs and distribution changes observed after acute thoracic trauma. Thirty rabbits were randomly divided into a control group and two study groups. The control group animals underwent an esophagectomy. All animals in the study groups underwent right chest puncture using the Hopkinson bar technique. The study groups were subjected to esophagectomy 24 and 72 h after chest puncture. Distribution, morphology, and density of esophageal ICCs were detected using transmission electron microscopy, toluidine blue staining, and immunohistochemistry. Apoptosis of esophageal ICCs was evaluated using the terminal deoxynucleotidyl transferase (TdT) dUTP Nick-End Labeling assay. Western blotting and reverse transcription polymerase chain reaction were used to detect changes in the SCF/c-kit signaling pathway. Esophageal ICCs distribution and SCF/c-kit signal pathway decreased from the upper part to the lower part in both physiological state and after thoracic trauma. In contrast, death of ICCs increased from the upper part to the lower part, both in physiological and injured state (P < 0.05). After thoracic trauma, increased ICCs and decreased death of ICCs in all parts of the esophagus (P < 0.05) were observed. The observed distribution and changes in esophageal ICCs would have an impact on motility and motility disorders of the esophagus.

Lung failure after polytrauma with concomitant thoracic trauma in the elderly: an analysis from the TraumaRegister DGU®

Background

In developed countries worldwide, the number of older patients is increasing. Pulmonary complications are common in multiple injured patients with chest injuries. We assessed whether geriatric patients develop lung failure following multiple trauma with concomitant thoracic trauma more often than younger patients.

Methods

A retrospective analysis of severely injured patients with concomitant blunt thoracic trauma registered in the TraumaRegister DGU® (TR-DGU) between 2009 and 2018 was performed. Patients were categorized into four age groups: 55–64 y, 65–74 y, 75–84 y, and ≥ 85 y. Adult patients aged 18–54 years served as a reference group. Lung failure was defined as PaO2/FIO2 ≤ 200 mm Hg, if mechanical ventilation was performed.

Results

A total of 43,289 patients were included, of whom 9238 (21.3%) developed lung failure during their clinical stay. The rate of posttraumatic lung failure was seen to increase with age. While lung failure markedly increased the length of hospital stay, duration of mechanical ventilation, and length of ICU stay independent of the patient’s age, differences between younger and older patients with lung failure in regard to these parameters were clinically comparable. In addition, the development of respiratory failure showed a distinct increase in mortality with higher age, from 16.9% (18–54 y) to 67.2% (≥ 85 y).

Conclusion

Development of lung failure in severely injured patients with thoracic trauma markedly increases hospital length of stay, length of ICU stay, and duration of mechanical ventilation in patients, regardless of age. The development of respiratory failure appears to be related to the severity of the chest trauma rather than to increasing patient age. However, the greatest effects of lung failure, particularly in terms of mortality, were observed in the oldest patients.

Surgical stabilization versus nonoperative treatment for flail and non-flail rib fracture patterns in patients with traumatic brain injury

Purpose

Literature on outcomes after SSRF, stratified for rib fracture pattern is scarce in patients with moderate to severe traumatic brain injury (TBI; Glasgow Coma Scale ≤ 12). We hypothesized that SSRF is associated with improved outcomes as compared to nonoperative management without hampering neurological recovery in these patients.

Methods

A post hoc subgroup analysis of the multicenter, retrospective CWIS-TBI study was performed in patients with TBI and stratified by having sustained a non-flail fracture pattern or flail chest between January 1, 2012 and July 31, 2019. The primary outcome was mechanical ventilation-free days and secondary outcomes were in-hospital outcomes. In multivariable analysis, outcomes were assessed, stratified for rib fracture pattern.

Results

In total, 449 patients were analyzed. In patients with a non-flail fracture pattern, 25 of 228 (11.0%) underwent SSRF and in patients with a flail chest, 86 of 221 (38.9%). In multivariable analysis, ventilator-free days were similar in both treatment groups. For patients with a non-flail fracture pattern, the odds of pneumonia were significantly lower after SSRF (odds ratio 0.29; 95% CI 0.11–0.77; p = 0.013). In patients with a flail chest, the ICU LOS was significantly shorter in the SSRF group (beta, − 2.96 days; 95% CI − 5.70 to − 0.23; p = 0.034).

Conclusion

In patients with TBI and a non-flail fracture pattern, SSRF was associated with a reduced pneumonia risk. In patients with TBI and a flail chest, a shorter ICU LOS was observed in the SSRF group. In both groups, SSRF was safe and did not hamper neurological recovery.

Iatrogenic rib fractures and the associated risks of mortality

PURPOSE

Rib fractures, though typically associated with blunt trauma, can also result from complications of medical or surgical care, including cardiopulmonary resuscitation. The purpose of this study is to describe the demographics and outcomes of iatrogenic rib fractures.

METHODS

Patients with rib fractures were identified in the 2016 National Inpatient Sample. Mechanism of injury was defined as blunt traumatic rib fracture (BTRF) or iatrogenic rib fracture (IRF). IRF was identified as fractures from the following mechanisms: complications of care, drowning, suffocation, and poisoning. Differences between BTRF and IRF were compared using rank-sum test, Chi-square test, and multivariable regression.

RESULTS

34,644 patients were identified: 33,464 BTRF and 1180 IRF. IRF patients were older and had higher rates of many comorbid medical disorders. IRF patients were more likely to have flail chest (6.1% versus 3.1%, p < 0.001). IRF patients were more likely to have in-hospital death (20.7% versus 4.2%, p < 0.001) and longer length of hospitalization (11.8 versus 6.9 days, p < 0.001). IRF patients had higher rates of tracheostomy (30.2% versus 9.1%, p < 0.001). In a multivariable logistic regression of all rib fractures, IRF was independently associated with death (OR 3.13, p < 0.001). A propensity matched analysis of IRF and BTRF groups corroborated these findings.

CONCLUSION

IRF injuries are sustained in a subset of extremely ill patients. Relative to BTRF, IRF is associated with greater mortality and other adverse outcomes. This population is understudied. The etiology of worse outcomes in IRF compared to BTRF is unclear. Further study of this population could address this disparity.

Azygos vein lacerations, a rare injury from high-impact chest trauma: Two cases and a review of the literature

INTRODUCTION

Thoracic trauma is a significant cause of mortality, being responsible for 25% of trauma deaths. Despite this, azygos vein lacerations are rare, with only 35 published cases. We present two cases of azygos vein laceration over 21 years from 1999 to 2020 at a Level One Trauma Centre in Melbourne, Australia, as well as a review of the literature.

CASE PRESENTATIONS

The first case is a 38-year-old male who fell eight metres from a motorbike jump. He arrived in our emergency department in extremis. The second case is an 81-year-old female driver who presented following a motor vehicle crash. Both patients had massive right haemothorax and haemodynamic instability, so were transferred to the operating theatre for emergency thoracotomies. Both patients survived to hospital discharge.

DISCUSSION

Of the 37 cases of azygos vein injury, including our two, 36 were due to blunt trauma and one from penetrating trauma. Sixteen survived to hospital discharge, producing a 43% mortality rate. Only one of these survivors was managed non-operatively, the remainder underwent emergency thoracotomy and azygos vein ligation. The mortality rate reduced to 31% in those who underwent thoracotomy (n = 29). Presentation was predominantly with shock (83%) and right hemithorax white-out on chest x-ray (81%).

CONCLUSION

Azygos vein injuries are a rare but important cause of thoracic haemorrhage in high-impact blunt trauma. They are often fatal, so management relies on expedient transfer to theatre.

The use of ultrasound in establishing COVID-19 infection as part of a trauma evaluation

Purpose

The use of lung ultrasound for diagnosis of COVID-19 has emerged during the pandemic as a beneficial diagnostic modality due to its rapid availability, bedside use, and lack of radiation. This study aimed to determine if routine ultrasound (US) imaging of the lungs of trauma patients with COVID-19 infections who undergo extended focused assessment with sonography for trauma (EFAST) correlates with computed tomography (CT) imaging and X-ray findings, as previously reported in other populations.

Methods

This was a prospective, observational feasibility study performed at two level 1 trauma centers. US, CT, and X-ray imaging were retrospectively reviewed by a surgical trainee and a board-certified radiologist to determine any correlation of imaging findings in patients with active COVID-19 infection.

Results

There were 53 patients with lung US images from EFAST available for evaluation and COVID-19 testing. The overall COVID-19 positivity rate was 7.5%. COVID-19 infection was accurately identified by one patient on US by the trainee, but there was a 15.1% false-positive rate for infection based on the radiologist examination.

Conclusions

Evaluation of the lung during EFAST cannot be used in the trauma setting to identify patients with active COVID-19 infection or to stratify patients as high or low risk of infection. This is likely due to differences in lung imaging technique and the presence of concomitant thoracic injury.

"Early results after initiation of a rib fixation programme: A propensity score matched analysis"

INTRODUCTION

Chest wall injuries are very common in blunt trauma and development of treatment protocols can significantly improve outcomes. Surgical stabilisation of rib fractures (SSRF) is an adjunct for the most severe chest injuries and can be used as a part of a comprehensive approach to chest injuries care. We hypothesized that implementation of a SSRF programme program would result in improved short-term outcomes.

MATERIALS AND METHODS

The characteristics of the initial group of SSRF patients (Early-SSRF) were used to identify matching factors. Patients prior to SSRF protocol underwent a propensity score match, followed by screening for operative indications and contraindications. After exclusions, a non-operative (Non-Op) cohort was defined (n=36) resulting in an approximately 1:1 match. An overall operative cohort, inclusive of Early-SSRF and all subsequent operative patients, was defined (All- SSRF). A before-and-after analysis using chi-squared, Students T-tests, and Mann-Whitney U-tests were used to assess significance at the level of 0.05.

RESULTS

Early-SSRF (n=22) and All-SSRF (n=45) were compared to Non-Op (n=36). The selection process resulted in well matched groups, and equally well-balanced operative indications between the groups. The Early-SSRF group demonstrated shortened duration of mechanical ventilation and a decreased frequency of being discharged a long-term acute care hospital. The All-SSRF group again demonstrated markedly shorter duration of mechanical ventilation compared to Non-Op (median 6 days vs 16 days, p < 0.01), more decrease discharge to a long-term acute care hospital (9% vs. 36%, p=0.01), and reduced risk for tracheostomy (8.9% vs. 33.3% respectively, p<0.01) CONCLUSION: The introduction of an operative rib fixation to a comprehensive chest wall injury protocol can produce improvements in clinical outcomes that decrease time on the ventilator and tracheostomy rates, and result in more patients being discharged to home. Creation and implementation of a chest wall injury protocol to include SSRF requires a multidisciplinary approach and thoughtful patient selection.

Lung Ultrasound for Pulmonary Contusions

Lung ultrasound (LUS) has high sensitivity for the rapid and reliable diagnosis of pulmonary contusions (PC) in patients who have sustained trauma. LUS diagnosis of PC exceeds that of thoracic radiographs in multiple animal and human studies. The sonographer should understand potential caveats and confounding variables for proper diagnosis of PC with LUS. LUS does not replace conventional radiography or computed tomography, especially in the polytrauma patient. LUS should be used concurrently with other point-of-care ultrasound trauma protocols to rapidly optimize patient assessment before movement to the radiology suite.

Transfixing heart injury by stab wound: Case report

Cardiac impalement is a rare and usually fatal injury. Immediate recognition and surgical intervention are decisive factors for patient survival. This is a reported case of cardiac impalement with left ventricular transfixation, whose prehospital management, surgical treatment and postoperative care were successful.

Epidemiological and clinical characteristics of road traffic crashes related thoracic traumas: analysis of 5095 hospitalized chest injury patients

BACKGROUND

Road traffic crashes related (RTCR) chest traumas remain important global public health challenge. The impact of boosting market of automobile vehicles in China during last decade on thoracic injury needs to be defined. This study aimed to review and analyze the demographic and clinical characteristics of RTCR thoracic injuries in China.

METHODS

Clinical records of patients with thoracic trauma admitted to thoracic surgery department between January 2003 and June 2020 were retrospectively retrieved and reviewed. Patients' profiles and clinical characteristics were comparatively analyzed between road traffic crashes caused injury and other injury mechanisms, and in RTCR chest trauma patients before January 2011 (2003 group), and after January 2011 (2011 group), when is considered as the beginning year of Chinese household vehicle era.

RESULTS

The study included 5095 thoracic trauma patients with mean age of 50.2 years, of whom 79.4% were male. Most of the patients (70.3%, n = 3583) had rib fractures. Associated injuries were present in 52.0% of the patients, of them 78.5% (n = 2080) were extremity fractures. Road traffic crashes accounted for 41.4% (n = 2108) of the injuries, most of them (98.0%) were related to motor vehicles. In comparison with other chest trauma mechanisms, RTCR chest injuries affected females and older males more frequently, with a higher incidence of rib fractures and sternum fractures, and higher injury severity scores (ISS) (all p < 0.05). Surgeries were required in 1495 (70.9%) patients of the RRTCR chest traumas, while the majority of non-RTCR thoracic injuries were managed conservatively or with tube thoracostomy (30.2%, n = 901). RTCR chest traumas caused longer hospital stay (13.0 ± 9.6 days vs. 11.8 ± 7.4 days, p = 0.001), higher ICU usage (30.7% vs. 19.6%, p = 0.001), higher rate of ventilator support (12.9% vs. 7.5%, p = 0.001), and higher mortalities (3.8% vs. 1.6%, p = 0.005) than that of non-RTRA chest injuries. For RTCR patients, when compared with 2003 group, 2011 group had similar patterns in terms of accident category, associated injury and treatment. However, 2011 group had more females (38.5% vs. 18.0%, p = 0.001) and older males (50.6 ± 9.7 vs. 47.9 ± 17.2, p = 0.001), with a higher ISS (18.3 ± 10.2 vs. 17.1 ± 8.9, p = 0.004), and fewer were managed with chest tubes (25.0% vs. 29.2%, p = 0.031). Clinical outcomes were not significantly different between the groups in terms of hospital length of stay, intensive care unit (ICU) usage, ICU length of stay, duration of ventilator hours and mortality. However, the 2011 group had more patients requiring ventilator support (14.4% vs. 10.6%, p = 0.011).

CONCLUSIONS

Road traffic crashes remain to be the major etiology of thoracic injuries in China, which usually affects middle-aged males, causing rib fractures with concomitant injuries frequently occurring to other organ systems. Treatments mainly include tube thoracotomy and surgical procedures. Although the clinical characteristics and outcomes of traffic accident related chest traumas are largely unchanged in spite of the rapid increasing numbers of motor vehicles, variations in the pattern of injuries by gender, age, injury severity and ventilator usage may still provide important information for targeted management.

The ROX index as a predictor of standard oxygen therapy outcomes in thoracic trauma

BACKGROUND

Thoracic trauma is commonplace and accounts for 50-70% of the injuries found in severe trauma. Little information is available in the literature as to timing of endotracheal intubation. The main objective of this study was to assess the accuracy of the ROX index in predicting successful standard oxygen (SO) therapy outcomes, and in pre-empting intubation.

METHODS

Patient selection included all thoracic trauma patients treated with standard oxygen who were admitted to a Level I trauma center between January 1, 2013 and April 30, 2020. Successful standard SO outcomes were defined as non-requirement of invasive mechanical ventilation within the 7 first days after thoracic trauma.

RESULTS

One hundred seventy one patients were studied, 49 of whom required endotracheal intubation for acute respiratory distress (28.6%). A ROX index score ≤ 12.85 yielded an area under the ROC curve of 0.88 with a 95% CI [0.80-0.94], 81.63sensitivity, 95%CI [0.69-0.91] and 88.52 specificity, 95%CI [0.82-0.94] involving a Youden index of 0.70. Patients with a median ROX index greater than 12.85 within the initial 24 h were less likely to require mechanical ventilation within the initial 7 days of thoracic trauma.

CONCLUSION

We have shown that a ROX index greater than 12.85 at 24 h was linked to successful standard oxygen therapy outcomes in critical thoracic trauma patients. It is our belief that an early low ROX index in the initial phase of trauma should heighten vigilance on the part of the attending intensivist, who has a duty to optimize management.

Rib fracture fixation in a patient on veno-venous ECMO for severe blunt thoracic trauma

Thoracic chest wall trauma is a common injury in patients admitted to hospital following injury and is associated with high mortality. British Orthopaedic Association Standards for Trauma and Orthopaedics guidelines recommend consideration of rib fracture fixation in patients with flail chest wall injuries with respiratory compromise or uncontrollable pain. Veno-venous extracorporeal membrane oxygenation (ECMO) can be utilised in patients with severe respiratory dysfunction and we present the case of a patient who underwent rib fracture fixation while receiving ECMO. A 32-year-old male was admitted to our department following a 4.5m fall. He sustained significant thoracic injuries with multiple ribs fractures and a flail segment from the right fourth to ninth ribs. Treatment consisted of bilateral chest drains, ECMO support, tracheostomy and rib fracture fixation to the eighth and ninth ribs. The patient made a rapid recovery following surgery and ECMO support was ceased 2.5 days postoperatively. The case shows that a well-prepared, combined specialty surgical team can safely perform rib fixation for a patient on ECMO.

"Do You Need a Doctor's Note?" Factors Leading to Delayed Return to Work after Blunt Chest Trauma

BACKGROUND

Blunt chest trauma is associated with significant morbidity, but the long-term functional status for these patients is less well-known. Return to work (RTW) is a benchmark for functional recovery in trauma patients, but minimal data exist regarding RTW following blunt chest trauma.

MATERIALS AND METHODS

Patients ≥ 18 y old admitted to a Level 1 trauma center following blunt chest trauma with ≥ 3 rib fractures and length of stay (LOS) ≥ 3 d were included. An electronic survey assessing RTW was administered to patients after discharge. Patients were stratified as having delayed RTW (> 3 mo after discharge) or self-reported worse activities-of-daily-living (ADL) function after injury. Patient demographics, outcomes, and injury characteristics were compared between groups.

RESULTS

Median time to RTW was 3 mo (IQR 2,5). Patients with delayed RTW had higher odds of having more rib fractures than those with RTW ≤ 3 mo (median 10 versus 7; OR:1.24, 95%CI:1.04,1.48) as well as a longer LOS (median 13 versus 7 d; OR:1.15, 95% CI:1.04,1.30). Patients with stable ADL after trauma returned to work earlier than those reporting worse ADL (median 2 versus 3.5 mo, P < 0.01). 23.6% of respondents took longer than 5 mo to return to independent functioning, and 50% of respondents' report limitations in daily activities due to physical health after discharge.

CONCLUSIONS

The significant proportion of patients with poor physical health and functional status suggests ongoing burden of injury after discharge. Patients with longer LOS and greater number of rib fractures may be at highest risk for delayed RTW after injury.

Characteristics of pediatric thoracic trauma: in view of before and after the establishment of a regional trauma center

Purpose

Pediatric thoracic trauma differs from those of adult in terms of the small anatomy and rapid tissue recovery. Therefore, it is important to know the characteristics of the pediatric thoracic trauma to improve treatment results. In addition, this study examined the changes in pediatric thoracic trauma features and results from the establishment of a level 1 regional trauma center.

Methods

Data of 168 patients’ ≤ 15 years old diagnosed with thoracic trauma between 2008 and 2019 were retrospectively analyzed.

Results

Pedestrian traffic accidents were the most common cause of chest injury. The average injury severity score was 17.1 ± 12.4 and the average pediatric trauma score was 5.6 ± 4.1. Lung contusion was the most common in 134 cases. There were 48 cases of closed thoracostomy. There was one thoracotomy for cardiac laceration, one case for extracorporeal membranous oxygenation, and six cases for embolization. Of all, 25 patients died, providing a mortality rate of 14.9%. In addition, independent risk factors of in-hospital mortality were hemopneumothorax and cardiac contusion. Since 2014, when the level 1 regional trauma center was established, more severely injured thoracic trauma patients came. However, the mortality was similar in the two periods.

Conclusions

Understanding the clinical features of pediatric thoracic trauma patients can help in efficient treatment. In addition, as the severity of pediatric thoracic trauma patients has increased due to the establishment of the regional trauma center, so pediatric trauma center should be organized in regional trauma center to improve the outcomes of pediatric thoracic trauma.

Surgical stabilization of severe flail chest with Judet and Sanchez-Lloret plates. A case report

INTRODUCTION

Flail chest is now usually treated by conservative methods and surgical fixation remains indicated in selected cases. Different techniques can be used for fixation. The aim of this paper is to present a case in which Judet and Sanchez-Loret plates were employed and to discuss the usefulness of this traditional technique.

PRESENTATION OF CASE

A 79-year-old woman was admitted for left thoracic trauma with severe antero-lateral flail chest. She was affected by COPD with chronic respiratory failure, ischemic heart disease, autoimmune thrombocytopenia treated on chronic steroid therapy and severe osteoporosis. CT-scan detected multiple rib fractures, left hemothorax and lung contusions. An initial conservative treatment of flail chest involved compressive bandage and then internal pneumatic stabilization in ICU, but it failed. The patient underwent successful surgical treatment of the flail chest by fixation of the anterior fractures from the second to the eight rib. Judet and Sanchez-Lloret plates were used. A bilateral pneumonia developed during the rehabilitation period and the patient died two months after operation.

DISCUSSION

Judet and Sanchez-Lloret plates represent a traditional technique for fixation of flail chest. This technique is less and less used and progressively replaced by newer materials, especially titanium plates with screws or intramedullary struts. Our patient had multiple comorbidities and a very fragile bones that advised against use of screws or intramedullary struts.

CONCLUSION

Judet and Sanchez-Lloret plates can be still considered a useful tool for the fixation of flail chest in cases of thin and fragile bones.

Traumatic thoracic rib cage and chest wall hernias: A review and discussion of management principles

Traumatic thoracic or chest wall hernias are relatively uncommon but highly challenging injuries that can be seen after a variety of injury mechanisms. Despite their description throughout history there remains scant literature on this topic that is primarily limited to case reports or series. Until recently, there also has been no effort to create a reliable grading system that can assess severity, predict outcomes, and guide the choice of surgical repair. The purpose of this article is to review the reported literature on this topic and to analyze the history, common injury mechanisms, likely presentations, and optimal management strategies to guide clinicians who are faced with these challenging cases. We also report a modified and updated version of our previously developed grading system for traumatic chest wall hernias that can be utilized to guide surgical management techniques and approaches.

Isolated open bronchus fracture after open die forging

We present a case of an isolated open bronchus rupture following blunt thoracic trauma. Tracheobronchial injuries (TBI) following blunt chest trauma are a rare but possibly life-threatening condition. Though typically associated with additional injuries, high-energy blunt trauma led to perforating chest wound alone. A bronchial injury has not been seen neither in preoperative CT scan nor intraoperatively. This underlines the strong need for bronchoscopy in chest trauma as the only definitive diagnostic in bronchial lesions.

Isolated Thoracic Injury Patients With Rib Fractures Undergoing Rib Fixation Have Improved Mortality

BACKGROUND

Despite a lack of consensus recommendations for surgical stabilization of rib fractures (SSRF), SSRF has increased over the past decade. Outcomes of patients with isolated thoracic injuries undergoing SSRF are unknown. We hypothesized adult trauma patients with isolated thoracic injuries and rib fractures undergoing SSRF would have a decreased risk of mortality and in-hospital respiratory complications compared with those not undergoing SSRF.

MATERIALS AND METHODS

The Trauma Quality Improvement Program (2010-2016) was queried for patients presenting with a rib fracture. Patients who died in the emergency department or within 24-h, as well as those with a grade>1 for abbreviated injury scale of the head, face, neck, spine, abdomen, and extremities, were excluded. A multivariable logistic regression analysis was performed.

RESULTS

From 60,000 patients with isolated thoracic injuries and rib fractures, 688 (1.1%) underwent SSRF. Compared with patients without SSRF, those undergoing SSRF had a similar median age (P = 0.83) and higher injury severity score (P < 0.001). Patients undergoing SSRF had a longer length of stay (P < 0.001), higher rate of acute respiratory distress syndrome (P < 0.001), unplanned intubation (P < 0.001), and pneumonia (P < 0.001) but lower rate of mortality (0.9% versus 1.7%, P = 0.084). After adjusting for confounding variables, patients undergoing SSRF had a decreased associated risk of mortality (OR 0.40, P = 0.036) compared with those not undergoing SSRF.

CONCLUSIONS

The risk of mortality in trauma patients with isolated thoracic injuries and rib fractures is lower when undergoing SSRF despite being associated with a higher rate of respiratory complications during their increased length of stay.

Effectiveness of Delayed Intrapleural Alteplase Instillation for Infected Residual Traumatic Hemothorax. Case Report

In thoracic trauma, many cases may present with hemothorax, and, of those, a portion can complicate in empyema. These cases can reveal themselves to be of difficult management, particularly in peripheral hospitals with complicated access to thoracic surgery. Intrapleural fibrinolytic instillation can be of use and has been widely reported, mostly in the case of empyema. In the literature, the use of fibrinolytics in hemothorax mostly pertained to the older fibrinolytics, such as streptokinase and urokinase. Recent studies describe the use of alteplase in these patients but mostly in the first days after the trauma, when it becomes clear that the first chest tube is not being effective. We report a case of residual traumatic hemothorax that could not be evacuated after multiple chest tubes placements and was finally cleared after instillation of alteplase late in the course of the disease.

Analysis of the therapeutic effect and prognosis in 86 cases of rib fractures and atelectasis

Background

The aim of the present study was to explore the therapeutic effect and prognosis in patients with rib fractures and atelectasis after thoracic trauma in order to provide a basis for clinical decision-making in primary hospitals.

Methods

A retrospective study was conducted on 86 patients admitted to our hospital between January 2016 and May 2020 with rib fractures and atelectasis after thoracic trauma. On the basis of the chest computed tomography scans taken at the time of discharge, the patients were divided into two groups: the reexpansion group and the non-reexpansion group. The two groups were compared with respect to the changes observed in the patients’ levels of blood oxygen saturation (SpO2) and pulmonary function, the presence of secondary pulmonary or thoracic infection, the time of chest tube drainage, the length of hospitalization, the cost of hospitalization, and the patients’ level of satisfaction with their quality of life 3 months after discharge.

Results

In the reexpansion group, there were significant differences in the levels of SpO2 and pulmonary function measured before and after pulmonary reexpansion (P < 0.05). Compared with the non-reexpansion group, the patients in the reexpansion group had a lower incidence of secondary pulmonary and thoracic infection and a higher level of satisfaction with their quality of life after discharge; these differences were statistically significant (P < 0.05). There was no statistical significance between the two groups with respect to the time of chest tube drainage or the length of hospitalization (P > 0.05). However, the cost of hospitalization was significantly higher in the reexpansion group than in the non-reexpansion group (P < 0.05).

Conclusions

The patients in the pulmonary reexpansion group had a lower incidence of complications and a better prognosis than the patients in the non-reexpansion group.

Major penetrating thoracic trauma - The importance of collaboration between different specialties

Introduction

Penetrating thoracic trauma presents a rare and serious condition with great diversity in impalement mechanisms and following injuries, resulting in a high mortality. This case reports successful management of a severe thoracic trauma and need for collaboration between surgical specialties.

Presentation of case

An 18-year-old, otherwise healthy, Caucasian female had penetration of the chest with a wooden post due to a solo car accident and was admitted to a Level 1 trauma center at a university hospital. Trauma computed tomography scan showed costa fractures and fracture of the left clavicular bone. Damage to the subclavian artery, the brachial plexus and pulmonary artery were suspected. Extracorporeal circulation was on standby at surgery. However, removal of the foreign object did not result in any major bleeding. The patient was discharged from hospital on the 19th day after surgery. Fifteen months after the trauma, surgery was performed to remove the first two costae on the left side, as a disfiguring prominence on the neck was the patients' only complaint.

Discussion

Initial management of the patient should follow ATLS® principles with stabilization of airways, breathing and circulation. Multidisciplinary approach resulted in reconstruction of vessels, debridement and wound closure. The importance of follow-up after trauma and surgery are underlined by the current case, as the patient required additional surgery at follow up.

Conclusion

Multidisciplinary approach to the current penetrating trauma resulted in rapid assessment of injuries and management with excellent outcome.
