Management of complex pediatric and adolescent liver trauma: adult vs pediatric level 1 trauma centers.

PURPOSE: Management of high-grade pediatric and adolescent liver trauma can be complex. Studies suggest that variation exists at adult (ATC) vs pediatric trauma centers (PTC); however, there is limited granular comparative data. We sought to describe and compare the management and outcomes of complex pediatric and adolescent liver trauma between a level 1 ATC and two PTCs in a large metropolitan city. METHODS: A retrospective review of pediatric and adolescent (age < 21 years) patients with American Association for the Surgery of Trauma (AAST) Grade 4 and 5 liver injuries managed at an ATC and PTCs between 2016 and 2022 was performed. Demographic, clinical, and outcome data were obtained at the ATC and PTCs. Primary outcomes included rates of operative management and use of interventional radiology (IR). Secondary outcomes included packed red blood cell (pRBC) utilization, intensive care unit (ICU) length of stay (LOS), and hospital LOS. RESULTS: One hundred forty-four patients were identified, seventy-five at the ATC and sixty-nine at the PTC. The cohort was predominantly black (65.5%) males (63.5%). Six injuries (8.7%) at the PTC and forty-five (60%) injuries at the ATC were penetrating trauma. Comparing only blunt trauma, ATC patients had higher Injury Severity Score (median 37 vs 26) and ages (20 years vs 9 years). ATC patients were more likely to undergo operative management (26.7% vs 11.0%, p = 0.016) and utilized IR more (51.9% vs 4.8%, p < 0.001) compared to the PTC. The patients managed at the ATC required higher rates of pRBC transfusions though not statistically significant (p = 0.06). There were no differences in mortality, ICU, or hospital LOS. CONCLUSION: Our retrospective review of high-grade pediatric and adolescent liver trauma demonstrated higher rates of IR and operating room use at the ATC compared to the PTC in the setting of higher Injury Severity Score and age. While the PTC successfully managed > 95% of Grade 4/5 liver injuries non-operatively, prospective data are needed to determine the optimal algorithm for management in the older adolescent population. LEVEL OF EVIDENCE: Level IV.

Characteristics of traumatic major haemorrhage in a tertiary trauma center.

BACKGROUND: Major traumatic haemorrhage is potentially preventable with rapid haemorrhage control and improved resuscitation techniques. Although advances in prehospital trauma management, haemorrhage is still associated with high mortality. The aim of this study was to use a recent pragmatic transfusion-based definition of major bleeding to characterize patients at risk of major bleeding and associated outcomes in this cohort after trauma. METHODS: This was a retrospective cohort study including all trauma patients (n = 7020) admitted to a tertiary trauma center from January 2015 to June 2020. The major bleeding cohort (n = 145) was defined as transfusion of 4 units of any blood components (red blood cells, plasma, or platelets) within 2 h of injury. Univariate and multivariable logistic regression analyses were performed to identify risk factors for 24-hour and 30-day mortality post trauma admission. RESULTS: In the major bleeding cohort (n = 145; 145/7020, 2.1% of the trauma population), there were 77% men (n = 112) and 23% women (n = 33), median age 39 years [IQR 26-53] and median Injury Severity Score (ISS) was 22 [IQR 13-34]. Blunt trauma dominated over penetrating trauma (58% vs. 42%) where high-energy fall was the most common blunt mechanism and knife injury was the most common penetrating mechanism. The major bleeding cohort was younger (OR 0.99; 95% CI 0.98 to 0.998, P = 0.012), less female gender (OR 0.66; 95% CI 0.45 to 0.98, P = 0.04), and had more penetrating trauma (OR 4.54; 95% CI 3.24 to 6.36, P = 0.001) than the rest of the trauma cohort. A prehospital (OR 2.39; 95% CI 1.34 to 4.28; P = 0.003) and emergency department (ED) (OR 6.91; 95% CI 4.49 to 10.66, P = 0.001) systolic blood pressure < 90 mmHg was associated with the major bleeding cohort as well as ED blood gas base excess < -3 (OR 7.72; 95% CI 5.37 to 11.11; P < 0.001) and INR > 1.2 (OR 3.09; 95% CI 2.16 to 4.43; P = 0.001). Emergency damage control laparotomy was performed more frequently in the major bleeding cohort (21.4% [n = 31] vs. 1.5% [n = 106]; OR 3.90; 95% CI 2.50 to 6.08; P < 0.001). There was no difference in transportation time from alarm to hospital arrival between the major bleeding cohort and the rest of the trauma cohort (47 [IQR 38;59] vs. 49 [IQR 40;62] minutes; P = 0.17). However, the major bleeding cohort had a shorter time from ED to first emergency procedure (71.5 [IQR 10.0;129.0] vs. 109.00 [IQR 54.0; 259.0] minutes, P < 0.001). In the major bleeding cohort, patients with penetrating trauma, compared to blunt trauma, had a shorter alarm to hospital arrival time (44.0 [IQR 35.5;54.0] vs. 50.0 [IQR 41.5;61.0], P = 0.013). The 24-hour mortality in the major bleeding cohort was 6.9% (10/145). All fatalities were due to blunt trauma; 40% (4/10) high energy fall, 20% (2/10) motor vehicle accident, 10% (1/10) motorcycle accident, 10% (1/10) traffic pedestrian, 10% (1/10) traffic other, and 10% (1/10) struck/hit by blunt object. In the logistic regression model, prehospital cardiac arrest (OR 83.4; 95% CI 3.37 to 2063; P = 0.007) and transportation time (OR 0.95, 95% CI 0.91 to 0.99, P = 0.02) were associated with 24-hour mortality. RESULTS: Early identification of patients at high risk of major bleeding is challenging but essential for rapid definitive haemorrhage control. The major bleeding trauma cohort is a small part of the entire trauma population, and is characterized of being younger, male gender, higher ISS, and exposed to more penetrating trauma. Early identification of patients at high risk of major bleeding is challenging but essential for rapid definitive haemorrhage control.

Hollow viscus perforation in blunt abdominal trauma: A 14-year experience from a trauma center.

BACKGROUND: Isolated perforations of hollow viscus (HV) represent less than 1% of injuries in blunt abdominal trauma (BAT). When they do present, they are generally due to high-impact mechanisms in the segments of the intestine that are fixed. The aim of this study is to determine the incidence of major HV injuries in BAT at the "Dr. Domingo Luciani" General Hospital (HDL), and address the literature gap regarding updated HV perforations following BAT, especially in low-income settings. METHODS: A retrospective review was conducted on the medical records of patients admitted to our trauma center with a diagnosis of complicated BAT with HV perforation over 14 years. RESULTS AND DISCUSSION: Seven hundred sixty-one patients were admitted under the diagnosis of BAT. Of them, 36.79% underwent emergency surgical resolution, and 6.04% had HV perforation as an operative finding. Almost half (44.44%) of these cases presented as a single isolated injury, while the remaining were associated with other intra-abdominal organ injuries. The most common lesions were Grade II-III jejunum and Grade I transverse colon, affecting an equal proportion of patients at 13.33%. In recent years, an increased incidence of HV injuries secondary to BAT has been observed. Despite this, in many cases, the diagnosis is delayed, so even in the presence of negative diagnostic studies, the surgical approach based on the trauma mechanism, hemodynamic status, and systematic reevaluation of the polytraumatized patient should prevail.

Delta Shock Index and higher incidence of emergency surgery in older adults with blunt trauma.

PURPOSE: Vital signs are important for predicting clinical outcomes in patients with trauma. However, their accuracy can be affected in older adults because hemodynamic changes are less obvious. This study aimed to examine the usefulness of changes in vital signs during transportation in predicting the need for hemostatic treatments in older patients with trauma. METHODS: This retrospective cohort study was conducted using data from the Japan Trauma Data Bank (2004-2019). Patients aged ≥ 65 years who were hemodynamically stable at the scene were included in this study. The incidence of emergency surgery within 12 h after hospital arrival was compared between patients with delta Shock Index (dSI) > 0.1 and those with dSI ≤ 0.1. Predicting ability was examined after adjusting for patient demographics, comorbidities, vital signs at the scene and on hospital arrival, Injury Severity Score, and abbreviated injury scale in each region. RESULTS: Among the 139,242 patients eligible for the study, 3,701 underwent urgent hemostatic surgery within 12 h. Patients with dSI > 0.1 showed a significantly higher incidence of emergency surgery than those with dSI ≤ 0.1 (871/16,549 [5.3%] vs. 2,830/84,250 [3.4%]; odds ratio (OR), 1.60 [1.48-1.73]; adjusted OR, 1.22 [1.08-1.38]; p = 0.001). The relationship between high dSI and a higher incidence of intervention was observed in patients with hypertension and those with decreased consciousness on arrival. CONCLUSION: High dSI > 0.1 was significantly associated with a higher incidence of urgent hemostatic surgery in older patients.

Effect of acute alcohol consumption on blunt bowel mesenteric injury: a retrospective analysis.

BACKGROUND: The effect of alcohol consumption on trauma remains controversial. The effects of alcohol on hemorrhage and peritonitis after blunt abdominal trauma have rarely been discussed. This study aimed to explore the effects of acute alcohol intoxication on the clinical characteristics, injury patterns, and outcomes in a surgical blunt bowel mesenteric injury (BBMI) cohort. METHODS: A retrospective data analysis was performed using trauma cases of patients who had been tested for alcohol and had surgically proven BBMI from a Trauma Registry System from 2009 to 2021. Patients were grouped according to their positive blood alcohol concentration (BAC; >0.5% vs. no BAC; less than 0.5% no BAC) upon arrival at the emergency department (ED). The injury characteristics, physiological parameters, and outcomes with respect to post-injury complications and mortality were assessed. RESULTS: In total, 142 patients with surgical BBMI were included. Of these, 116 and 26 patients were assigned to the BAC-negative and BAC-positive groups, respectively. The overall injury severity, injury pattern, and age were comparable between the groups. The patients in the BAC-positive group had a significantly lower systolic blood pressure (99 mmHg vs. 119 mmHg; p = 0.046), worse shock index (0.96 vs. 0.82; p = 0.048), and lower percentage and number of packed red blood cells transfused (34.6% vs. 57.8%; p = 0.032 and 0 U vs. 2 U; p = 0.031) than those in the BAC-negative group. Additionally, although not statistically significant, patients in the BAC-positive group had lower leukocyte counts (9,700 cells/mm3 vs. 11,600 cells/mm3; p = 0.165 ) at the ED. However, significantly reduced percentages of leukocytes ≥ 12,000 cells/mm3 (26.9% vs. 48.3%; p = 0.048) and ≥ 12,000 or ≤ 4,000 cells/mm3 (26.9% vs. 50.9%; p = 0.027) were observed in the BAC-positive group at the ED. Furthermore, the 30-day mortality rate did not show statistically significant differences, and there was a higher incidence of bowel-related mortality in the BAC-positive group (11.5% vs. 1.7%, p = 0.043). CONCLUSIONS: For patients with BBMI arriving alive to the hospital, acute alcohol consumption was associated with significantly worse hemodynamic parameters, interfered inflammation status, and higher bowel related mortality rate.

Prognostic factors associated with risk of stroke following blunt cerebrovascular injury: A systematic review and meta-analysis.

BACKGROUND & OBJECTIVES: Blunt cerebrovascular injury (BCVI) includes carotid and/or vertebral artery injury following trauma, and conveys an increased stroke risk. We conducted a systematic review and meta-analysis to provide a comprehensive summary of prognostic factors associated with risk of stroke following BCVI. METHODS: We searched the EMBASE and MEDLINE databases from January 1946 to June 2023. We identified studies reporting associations between patient or injury factors and risk of stroke following BCVI. We performed meta-analyses of odds ratios (ORs) using the random effects method and assessed individual study risk of bias using the QUIPS tool. We separately pooled adjusted and unadjusted analyses, highlighting the estimate with the higher certainty. RESULTS: We included 26 cohort studies, involving 20,458 patients with blunt trauma. The overall incidence of stroke following BCVI was 7.7 %. Studies were predominantly retrospective cohorts from North America and included both carotid and vertebral artery injuries. Diagnosis of BCVI was most commonly confirmed with CT angiography. We demonstrated with moderate to high certainty that factors associated with increased risk of stroke included carotid artery injury (as compared to vertebral artery injury, unadjusted odds ratio [uOR] 1.94, 95 % CI 1.62 to 2.32), Grade III Injury (as compared to grade I or II) (uOR 2.45, 95 % CI 1.88 to 3.20), Grade IV injury (uOR 3.09, 95 % CI 2.20 to 4.35), polyarterial injury (uOR 3.11 (95 % CI 2.05 to 4.72), occurrence of hypotension at the time of hospital admission (adjusted odds ratio [aOR] 1.32, 95 % CI 0.87 to 2.03) and higher total body injury severity (aOR 5.91, 95 % CI 1.90 to 18.39). CONCLUSION: Local anatomical injury pattern, overall burden of injury and flow dynamics contribute to BCVI-related stroke risk. These findings provide the foundational evidence base for risk stratification to support clinical decision making and further research.

Blunt Cerebrovascular Injury Complications in Aging Adults: A National Trauma Database Study.

INTRODUCTION: Blunt cerebrovascular injury (BCVI) is defined as a nonpenetrating injury to the carotid or vertebral arteries which can be highly morbid. Because BCVI is rare, most studies have been devoted to triaging trauma patients for BCVI identification, with little data available regarding the complications these patients experience after initial evaluation. Here, we analyze the association of complications during admission for BCVI patients. METHODS: The National Trauma Databank was queried from 2007 to 2014 for adults ≥65 y old. Demographics, incidence of BCVI, and injury data were evaluated using univariate analysis. Rates of inpatient complications due to acutely acquired infections and strokes were evaluated using univariate and multivariable analysis. RESULTS: We identified 666,815 non-BCVI and 552 BCVI patients. Patients with a BCVI were typically male, White, younger (65-75-y-old), had three or more comorbidities, and had Medicare insurance. BCVI patients had a mild head injury upon arrival at the emergency department and experienced a motor vehicle accident/fall. The median length of stay in the intensive care unit, days spent on a ventilator, and presence of polytrauma were higher among BCVI patients. BCVI patients had increased odds of experiencing a stroke and pneumonia as complications while admitted compared to their non-BCVI counterparts. CONCLUSIONS: Postinjury, patients who suffered a BCVI had higher odds of stroke and pneumonia than patients who did not experience a BCVI. Additional studies are needed to determine the modifiable risk factors associated with BCVIs among aging adults.

What Is Going on in Our Schools? Review of Injuries Among School Children Across the United States.

INTRODUCTION: Children spend most of their time at school and participate in many activities that have the potential for causing injury. This study aims to describe the nationwide epidemiology of pediatric trauma sustained in school settings in the United States. METHODS: In the 3-y analysis of 2017-2019 American College of Surgeons-Trauma Quality Program, all pediatric trauma patients (≤18 y) injured in a school setting were included and stratified based on place of injury, into elementary, middle, and high school (HS) groups. Descriptive statistics and multivariable logistic regression analysis were performed to identify the independent predictors of intentional injuries. RESULTS: 23,215 pediatric patients were identified, of which 15,264 patients were injured at elementary (57.6%), middle (17.5%), and high (25%) schools. The mean age was 9.5 y, 66.9% were male, 63.9% were white, the median injury severity score was 2 [1-4], and 95.6% had a blunt injury. Elementary school students were more likely to sustain falls (85%) and humerus fractures (43%) whereas HS students were more likely to be injured by assaults (17%). Overall, 7% of the students sustained intentional injuries. On multivariable logistic regression, male gender (odds ratio [OR] 1.54), Black race (OR 2.94), American Indian race (OR 1.88), Hispanic ethnicity (OR 1.77), positive drug screen (OR 4.9), middle (OR 5.2), and HSs (OR 10.6) were identified as independent predictors of intentional injury (all P < 0.01). CONCLUSIONS: Injury patterns vary across elementary, middle, and HSs. Racial factors appear to influence intentional injuries along with substance abuse. Further studies to understand these risk factors and efforts to reduce school injuries are warranted to provide a safe learning environment for children.

National Management Trends in Pediatric Splenic Trauma - Are We There yet?

INTRODUCTION: Guidelines recommend nonoperative management of blunt splenic injury (BSI) for hemodynamically stable children. The aim of this study was to determine the contemporary national trends of nonoperative management in pediatric BSI. METHODS: A retrospective review was preformed utilizing KIDS database between 2012 and 2019. Pediatric BSI cases age ≤16 years were selected for analysis. Patient demographics, severity, and interventions were compared between hospital types. RESULTS: 8,296 BSIs were identified, with 74.3% treated at non-pediatric hospitals. Overall, 96.3% of BSI were nonoperative; 2.5% undergoing angioembolization. Rates of splenectomy from 2012 to 2019 remained stable (6.8% versus 7.1% (p = 0.856)). Splenic injuries treated at adult hospitals were more likely to undergo operative management (11.9% versus 4.4%, OR 2.94, p < 0.001) and more likely to undergo angiography (4.8% vs 1.3%, OR 3.133, p < 0.001). On multivariate regression pediatric BSI treated at adult centers were associated with triple the risk of splenectomy (OR 3.50, p < 0.001). Over seven years, high grade BSI treated at children's hospitals increased from 14.6% to 51.7% (p < 0.001) and, splenectomy rates at children's hospitals increased from 1% to 4% (p < 0.001). CONCLUSION: More than 70% of pediatric splenic injuries are treated at adult hospitals, however, children's hospitals predominately caring for high-grade BSI. After controlling for confounding factors, children treated at adult centers continue to have 3-fold likelihood of splenectomy. Over the last 7 years, pediatric hospitals have seen a significant rise in their overall splenectomy rate, which may suggest a shift in case severity to children's hospitals. LEVEL OF EVIDENCE: Level III. TYPE OF STUDY: Treatment study.

Management Patterns and Outcomes After Traumatic Brain Injury With Associated Blunt Cerebrovascular Injury.

BACKGROUND AND OBJECTIVES: Although blunt cerebrovascular injuries (BCVIs) are relatively common in patients with traumatic brain injuries (TBIs), uncertainty remains regarding optimal management strategies to prevent neurological complications, morbidity, and mortality. Our objectives were to characterize common care patterns; assess the prevalence of adverse outcomes, including stroke, functional deficits, and death, by BCVI grade; and evaluate therapeutic approaches to treatment in patients with BCVI and TBI. METHODS: Patients with TBI and BCVI treated at our Level I trauma center from January 2016 to December 2020 were identified. Presenting characteristics, treatment, and outcomes were captured for univariate and multivariate analyses. RESULTS: Of 323 patients with BCVI, 145 had Biffl grade I, 91 had grade II, 49 had grade III, and 38 had grade IV injuries. Lower-grade BCVIs were more frequently managed with low-dose (81 mg) aspirin ( P < .01), although all grades were predominantly treated with high-dose (150-600 mg) aspirin ( P = .10). Patients with low-grade BCVIs had significantly fewer complications ( P < .01) and strokes ( P < .01). Most strokes occurred in the acute time frame (<24 hours), including 10/11 (90.9%) grade IV-related strokes. Higher BCVI grade portended elevated risk of stroke (grade II odds ratio [OR] 5.3, grade III OR 12.2, and grade IV OR 19.6 compared with grade I; all P < .05). The use of low- or high-dose aspirin was protective against mortality (both OR 0.1, P < .05). CONCLUSION: In patients with TBI, BCVIs impart greater risk for stroke and other associated morbidities as their severity increases. It may prove difficult to mitigate high-grade BCVI-related stroke, considering most events occur in the acute window. The paucity of late time frame strokes suggest that current management strategies do help mitigate risks.

Traumatic vertebral artery injury: Denver grade, bilaterality, and stroke risk. A systematic review and meta-analysis.

OBJECTIVE: Vertebral artery injury (VAI), a complication of blunt trauma, may cause posterior circulation stroke. An association of disease severity, classified in Denver grades, with stroke risk has not been shown. Using a literature-based analysis, the authors estimated the incidence of VAI following blunt trauma with the aim to investigate the impact of Denver grade and bilateral VAI on stroke occurrence. METHODS: A systematic review of the literature on VAI following blunt trauma was conducted, and data on its incidence, the severity per Denver grade, and stroke occurrence were collected. The incidence of VAI and stroke occurrence were analyzed cumulatively and between Denver grades. A meta-analysis with random-effects models was performed. RESULTS: Fifty-six studies including 2563 patients were identified. The overall incidence of VAI was 0.49% among blunt trauma cases and 14.5% among patients screened via any type of angiography. The incidence rates of bilateral VAI and concurrent carotid injury among all VAIs were 12.3% and 19.2%, respectively. VAI severity by Denver grade was as follows: grade I, 23.4%; grade II, 28.2%; grade III, 5.8%; grade IV, 42.1%; and grade V, 0.5%. The overall stroke risk was 5.32%, differing significantly among lesions of different Denver grades (p = 0.02). Grade III and IV lesions had the highest stroke prevalence (9.8% and 10.9% respectively), while strokes occurred significantly less frequently in patients with grade I and II lesions (1.9% and 3.0%, respectively). Denver grade V cases were too rare for meaningful analysis. Bilateral VAI was associated with a 33.2% stroke prevalence. The association between Denver grade and stroke occurrence persisted in a sensitivity subanalysis including only unilateral cases (p = 0.03). CONCLUSIONS: VAI complicates a small yet nontrivial fraction of blunt trauma cases, with Denver grade IV lesions being the most common. This is the first study to document a significantly higher stroke prevalence among grade III and IV VAIs compared with grade I and II VAIs independently from bilaterality. Bilateral VAIs carry a significantly higher stroke rate.

Performance of three predictive scores to avoid delayed diagnosis of significant blunt bowel and mesenteric injury: A 12-year retrospective cohort study.

BACKGROUND: Avoiding missed diagnosis and therapeutic delay for significant blunt bowel and mesenteric injuries (sBBMIs) after trauma is still challenging despite the widespread use of computed tomography (CT). Several scoring tools aiming at reducing this risk have been published. The purpose of the present work was to assess the incidence of delayed (>24 hours) diagnosis for sBBMI patients and to compare the predictive performance of three previously published scores using clinical, radiological, and laboratory findings: the Bowel Injury Prediction Score (BIPS) and the scores developed by Raharimanantsoa Score (RS) and by Faget Score (FS). METHODS: A population-based retrospective observational cohort study was conducted; it included adult trauma patients after road traffic crashes admitted to Lausanne University Hospital, Switzerland, between 2008 and 2019 (n = 1,258) with reliable information about sBBMI status (n = 1,164) and for whom all items for score calculation were available (n = 917). The three scores were retrospectively applied on all patients to assess their predictive performance. RESULTS: The incidence of sBBMI after road traffic crash was 3.3% (38 of 1,164), and in 18% (7 of 38), there was a diagnostic and treatment delay of more than 24 hours. The diagnostic performances of the FS, the RS, and the BIPS to predict sBBMI, expressed as the area under the receiver operating characteristic curve, were 95.3% (95% confidence interval [CI], 92.7-97.9%), 89.2% (95% CI, 83.2-95.3%), and 87.6% (95% CI, 81.8-93.3%) respectively. CONCLUSION: The present study confirms that diagnostic delays for sBBMI still occur despite the widespread use of abdominal CT. When CT findings during the initial assessment are negative or equivocal for sBBMI, using a score may be helpful to select patients for early diagnostic laparoscopy. The FS had the best individual diagnostic performance. However, the BIPS or the RS, relying on clinical and laboratory variables, may be helpful to select patients for early diagnostic laparoscopy when there are unspecific CT signs of bowel or mesenteric injury. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

Characterization of Ocular Injuries Caused by Orbeez Hydrated Gel Pellet Projectiles: Clinical Insights and Implications.

PURPOSE: To examine the clinical characteristics of patients who have experienced blunt ocular injuries from "Orbeez" hydrated gel pellets (Spin Master Corp.), and to describe ocular morbidity, visual acuity (VA), and intraocular pressure (IOP) after Orbeez-related ocular trauma. DESIGN: Retrospective, institutional, observational case series. METHODS: Patients sustaining Orbeez-related ocular trauma at a single institution over a 13-month period were identified. Clinical parameters including VA, IOP, and anterior and fundus examination findings were assessed upon initial and final presentation. Basic statistical testing was performed to compare differences within this cohort. RESULTS: A total of 17 eyes from 17 patients with Orbeez-related trauma were identified. Orbeez-related blunt ocular injuries included corneal abrasion (n = 7), hyphema (n = 9), commotio retinae (n = 5), intraretinal hemorrhage (n = 3), preretinal hemorrhage (n = 1), vitreous hemorrhage (n = 2), and retinal tear (n = 1). Adolescents (14-18 years of age) showed higher rates of posterior segment complications compared to other ages (P = .0152). The presence of elevated IOP and hyphema upon initial examination correlated with increased likelihood of requiring invasive treatment following Orbeez impact (P = .0275). CONCLUSION: Orbeez-related ocular trauma may be associated with severe visual morbidity and varied anterior and posterior segment intraocular sequelae. Adolescents could be at increased risk for posterior segment complications following these injuries. Initial findings of elevated IOP and hyphema may indicate a need for more aggressive interventions. Prevention remains paramount in managing Orbeez-related ocular trauma; it is critical to raise awareness regarding the importance of wearing eye protection meeting high-impact standards and minimizing exposure to such projectiles.

Clinical features and treatment of thoracic trauma in children. Eleven years of experience in a single center.

AIM: This study aims to evaluate the characteristics of thoracic trauma in children. MATERIAL AND METHOD: Thoracic trauma cases treated in our clinic between February 2011 and January 2022 were retrospectively analyzed. RESULTS: 31.5% (n=136) of 432 cases with thoracic trauma had isolated thoracic trauma. Mean age was 8.7±4 years, 74.3% were boys (n=321) and 25.7% were girls (n=111). In patients with thoracic trauma in children; blunt injuries were 84%, penetrating-stab wounds were 12%, and gunshot wounds were 4%, while the rate of penetrating trauma over the age of 15 was 24.8%. The most common causes were motor vehicle accidents (42.4%) and falls from height (23.9%). The most common pathologies; pulmonary contusion (71.7%), pneumothorax (48.7%), rib fracture (18%), and pulmonary laceration (12%). Tube thoracostomy was performed in 51 (46.4%) of 110 cases with pneumothorax. Thoracotomy was performed in 2 cases with penetrating gunshot wounds, and tube thoracostomy was performed in 2 cases with hemothorax. The mean hospital stay was 7 days, and1 case with severe cranial trauma died. CONCLUSION: Chest wall, pulmonary, mediastinal, and diaphragmatic structures can be damaged in chest trauma. However, it should be kept in mind that every chest trauma patient may also have polytrauma, and accompanying injuries should be carefully examined. KEY WORDS: Childhood, Thoracic trauma, Tube Thoracostomy.

Ocular trauma among patients attending a tertiary teaching hospital in Zimbabwe.

PURPOSE: To investigate the trends, prevalence and distribution of ocular trauma in a Zimbabwean Tertiary Teaching Hospital (Parirenyatwa). METHOD: A hospital-based retrospective cross-sectional study was conducted at the Parirenyatwa Group of Hospitals, Sekuru Kaguvi Eye Department in Harare, Zimbabwe, to review medical records of patients with ocular trauma visiting for treatment at the outpatient department between January 2017 and December 2021. Information on patients' demographics, presenting visual acuity, type of ocular trauma, and the number of eyes affected were collected and analysed using descriptive and inferential statistics. RESULTS: A total of 863 patients (1007 eyes) were identified to have experienced ocular trauma of one kind or another, with the youth (18-35 years) reporting with most cases (331, 38.4%). About 71.2% of patients were classified as having open-globe injuries and of that number, 90% were caused by blunt trauma, while the rest were caused by penetrating, intraocular, and perforating injuries. Patients with open-globe injuries were about 10 times more likely to develop blindness than those with closed-globe injuries after adjusting for age and gender, and this was statistically significant (ARR = 9.65, 95% CI: 5.53-16.84, p < 0.001). The prevalence of distance vision impairment due to ocular trauma was 60.1% (95% CI: 56.8%-63.4%), with majority resulting in blindness (22.0%, 95% CI: 19.4%-24.9%). CONCLUSION: There is a high prevalence of open-globe injuries in Zimbabwe with blunt trauma being the most significant cause. This suggests the need to promote and intensify public eye health awareness and sensitisation on safety strategies for the prevention of ocular trauma throughout the country.

Spectrum of paediatric blunt abdominal trauma in a tertiary care hospital in India.

Aim: To study the profile of paediatric blunt abdominal trauma and to assess the correlation of grade of injury with the outcome. Materials and Methods: It is a prospective observational study from January 2015 to December 2020. Children below 12 years with blunt abdominal trauma were included. Patient demographic data, treatment given and the final outcome were recorded. All patients were followed up for a minimum of 6 months to maximum 5 years. Results: A total of 68 patients were included in the study. Fall from height was the most common mode of injury (62%) followed by road traffic accidents (35%) and the other causes included in the miscellaneous group (hit by animal and fall of heavy object on the abdomen; 3%). Most commonly injured organ was liver (n = 28, 41%) followed by spleen (n = 18, 26%) and kidney (n = 15, 22%). Other injuries were bowel perforations (jejunal [n = 4], ileal [n = 1] and large bowel [n = 1]; 9%), pancreaticoduodenal (n = 5, 7%), urinary bladder (n = 3, 4%), abdominal vascular injury (iliac vein-1, inferior vena cava-1;3%), adrenal haematoma (n = 2,3%) and common bile duct (CBD) injury (n = 1, 1%). More than one organ injury was seen in 13 cases (19%). Non-operative management was successful in 84% (n = 27) and laparotomy was done in 16% (n = 11). Most of the patients sustained Grade IV injury (n = 36, 53%) and majority of the patients (n = 60, 88%) had good outcome without any long-term complications. Conclusion: Profile of paediatric blunt abdominal trauma include solid organ injuries such as liver, spleen, kidney, pancreas, adrenal gland and others like bowel injury, CBD, urinary bladder and abdominal vascular injury. The grade of injury does not correlate with the outcome in a higher grade of injury and these children had good outcome.

[Bilateral thoracic trauma-"double the trouble"?] / Beidseitiges Thoraxtrauma ­ "double the trouble"?

BACKGROUND: Thoracic trauma is associated with a high morbidity and mortality. Assessing the risk for complications is essential for planning the further treatment strategies and managing resources in thoracic trauma. OBJECTIVE: The aim of the study was to analyze concomitant injuries in unilateral and bilateral rib fractures and pulmonary contusions and evaluate differences in complication rates between the two. MATERIAL AND METHODS: In a retrospective study, data from all patients diagnosed with thoracic trauma at a level I trauma center were analyzed. Bivariate and multivariate analysis were used to examine an association of unilateral or bilateral rib fractures, serial rib fractures, and pulmonary contusions with multiple injuries and outcomes. In addition, multivariate regression analysis was utilized to determine the impact of age, gender and additional injuries on outcome. RESULTS: A total of 714 patients were included in the analysis. The mean Injury Severity Score (ISS) was 19. Patients with an additional thoracic spine injury had a significantly higher incidence of bilateral rib fractures. Pulmonary contusions were associated with younger age. Abdominal injuries were predictors for bilateral pulmonary contusions. Complications occurred in 36% of the patients. Bilateral injuries increased the complication rate up to 70%. Pelvic and abdominal injuries as well as the need for a chest drain were significant risk factors for complications. The mortality rate was 10%, with higher age, head and pelvic injuries as predictors. CONCLUSION: Patients with bilateral chest trauma had an increased incidence of complications and a higher mortality rate. Bilateral injuries and significant risk factors must therefore be considered. Injury of the thoracic spine should be excluded in those patients.

Trauma mechanisms and patterns of blunt cervical vascular injury: A descriptive study using a nationwide trauma registry.

OBJECTIVE: Blunt cervical vascular injury (BCVI) is a non-penetrating trauma to the carotid and/or vertebral vessels following a direct injury to the neck or by the shearing of the cervical vessels. Despite its potentially life-threatening nature, important clinical features of BCVI such as typical patterns of co-occurring injuries for each trauma mechanism are not well known. To address this knowledge gap, we described the characteristics of patients with BCVI to identify the pattern of co-occurring injuries by common trauma mechanisms. METHODS: This is a descriptive study using a Japanese nationwide trauma registry from 2004 through 2019. We included patients aged ≥13 years presenting to the emergency department (ED) with BCVI, defined as a blunt trauma to any of the following vessels: common/internal carotid artery, external carotid artery, vertebral artery, external jugular vein, and internal jugular vein. We delineated characteristics of each BCVI classified according to three damaged vessels (common/internal carotid artery, vertebral artery, and others). In addition, we applied network analysis to unravel patterns of co-occurring injuries among patients with BCVI by four common trauma mechanisms (car accident, motorcycle/bicycle accident, simple fall, and fall from a height). RESULTS: Among 311,692 patients who visited the ED for blunt trauma, 454 (0.1%) patients had BCVI. Patients with common/internal carotid artery injuries presented to the ED with severe symptoms (e.g., the median Glasgow Coma Scale was 7) and had high in-hospital mortality (45%), while patients with vertebral artery injuries presented with relatively stable vital signs. Network analysis showed that head-vertebral-cervical spine injuries were common across four trauma mechanisms (car accident, motorcycle/bicycle accident, simple fall, and fall from a height), with co-occurring injuries of the cervical spine and vertebral artery being the most common injuries due to falls. In addition, common/internal carotid artery injuries were associated with thoracic and abdominal injuries in patients with car accidents. CONCLUSIONS: Based on analyses of a nationwide trauma registry, we found that patients with BCVI had distinct patterns of co-occurring injuries by four trauma mechanisms. Our observations provide an important basis for the initial assessment of blunt trauma and could support the management of BCVI.

Twenty-year perspective on blunt traumatic diaphragmatic injury in level 1 trauma centre: Early versus delayed diagnosis injury patterns and outcomes.

OBJECTIVE: Blunt traumatic diaphragmatic injury (TDI) is typically associated with severe trauma and concomitant injuries. It is a diagnostic challenge in the setting of blunt trauma and can be easily overlooked especially in the acute phase often dominated by concurrent injuries. METHODS: A retrospective review was conducted of patients with blunt-TDI identified from a level 1 trauma registry. Variables associated with early versus delayed diagnosis as well as non-survivor and survivor groups were collected to examine factors associated with delayed diagnosis. RESULTS: A total of 155 patients were included (mean age 46 ± 20, 60.6% male). Diagnosis was made <24 h in 126 (81.3%), and >24 h in 29 (18.7%). Of the delayed diagnosis group, 14 (48%) were diagnosed >7 days. Overall, 27 (21.4%) patients had a diagnostic initial CXR and 64 (50.8%) had a diagnostic initial CT. Fifty-eight (37.4%) patients were diagnosed intraoperatively. Of the delayed diagnosis group, 22 (75.9%) had no initial signs on CXR or CT, 15 (52%) of this group had persistent pleural-effusions/elevated-hemidiaphragm leading to further investigation and diagnosis. No significant difference in survival was observed between early and delayed diagnoses, no clinically significant injury patterns to predict delayed diagnoses were noted. CONCLUSION: The diagnosis of TDI is challenging. Without frank signs of herniation of abdominal contents on CXR or CT, the diagnosis is often not made on initial imaging. In patients with the evidence of blunt traumatic injury in the lower-chest/upper-abdomen, a high degree of clinical suspicion should be held and follow-up CXRs/CTs arranged.

Trends of Trauma Admissions in a Rural Trauma Center During Coronavirus Disease 2019 Pandemic.

INTRODUCTION: The spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) led to implementing strict social distancing mandates nationwide. This study evaluates the trauma trends during the pandemic at a rural level II trauma center in Pennsylvania. METHODS: A retrospective review of all trauma registries between 2018 and 2021 was performed overall and on a 6-month basis. Injury severity score, injury types-blunt versus penetrating, and mechanisms of injury were compared across the years. RESULTS: A total of 3056 patients in 2018-2019 and 2506 patients in 2020-2021 were evaluated as the historic control and study group, respectively. The median age of the patients was 63 and 62 years in the control and the study group, respectively (P = 0.616). There was an overall significant decline in blunt injuries and an increase in penetrating injuries (Blunt: 2945 versus 2329, Penetrating: 89 versus 159, P < 0.001). Injury severity score was not different across the eras. Falls, motorcycle accidents, motor vehicle accidents, and all-terrain vehicles comprised most of the blunt traumas. Penetrating injuries secondary to assault with firearms and sharp weapons had an increasing trend. CONCLUSIONS: There was no association between trauma numbers and the beginning of the pandemic. Overall, there was a decline in trauma numbers during the second 6 mo of the pandemic. There was an increase in injuries involving firearms and stabbing. Rural trauma centers have a unique demographic and admission trend that should be considered while advising regulatory changes during pandemics.
