Pediatric Polytrauma Management

Epidemiology of Pediatric Transports and First Aid in a German Municipal Emergency Medical Services (EMS) System: A Cohort Study

Background: Pediatric emergencies remain a significant challenge for emergency services. The study aimed to retrospectively analyze invasive measures and medication administered during prehospital care. The analysis focused on invasive procedures (e.g., tracheal intubation and vascular access) performed on pediatric patients (aged 1 month to 12 years) admitted via the Central Emergency Department (ED) or directly to the University Pediatric Intensive Care Unit (PICU) of the University Hospital of Cologne. These findings provide insights into quality assurance and improvement of prehospital care and invasive emergency techniques in pediatrics. Methods: Emergency protocols were evaluated, including parameters such as the Glasgow Coma Scale (GCS) and National Advisory Committee for Aeronautics (NACA) score. Patients were categorized based on diagnosis, medication administration, and invasive emergency techniques. Results: A total of 373 patients were admitted to the ED, and 237 patients were admitted to the PICU between 01/2015 and 05/2020. Sedation was at similar in both groups, while catecholamines were more frequently used in the PICU group. Invasive procedures, such as tracheal intubation, were rare (PICU: 9.5%; ED: 5.8%; p=0.093). Peripheral venous access was performed in 33.7% of PICU cases and 51.2% of ED cases, whereas central venous access was almost never performed. 19 children admitted to the PICU died compared to one in the ED (p < 0.001). Conclusion: Invasive procedures are rarely performed during prehospital care for pediatric patients. Trauma cases predominated in the ED group (99.2%), whereas the PICU group exhibited greater diagnostic variability, including trauma and internal emergencies. This study identified significant gaps in medical documentation. Training for paramedics and emergency health workers should prioritize airway management, including supraglottic airway (SGA) devices, thoracic drainage, and vascular access techniques such as peripheral intravenous (PIV) and intraosseous (IO) access. Additionally, efforts to improve medical documentation should be emphasized to enhance pediatric emergency care.

The NACA score predicts mortality in polytrauma patients before hospital admission: a registry-based study

BACKGROUND

The early assessment of the severity of polytrauma patients is key for their optimal management. The aim of this study was to investigate the discriminative performance of the NACA score in a large dataset by stratifying the severity of polytraumatized patients in correlation to injury severity score (ISS), Glasgow Coma Scale (GCS), and mortality.

METHODS

This study on the Swiss Trauma Registry investigated 2239 polytraumatized patient (54.3 ± 22.8 years) enrolled from 2015 to 2023: 0.5% were NACA 3, 76.7% NACA 4, 21.4% NACA 5, and 1.4% NACA 6. The NACA predictive value of patients' mortality was investigated, as well as the correlation of ISS and GCS scores, and other factors influencing patients' survival at discharge and after 28 days.

RESULTS

In NACA 4 and 5 the survival rate during hospitalization was 97.7% and 82.5%, respectively, and 28-day mortality 3.5% and 23.5%, respectively (p < 0.0005). NACA correlated with GCS in the prehospital phase and in the emergency room (p < 0.0005), as well as with ISS (p < 0.0005). NACA 4 and 5 presented different injury patterns (fall < 3 m vs vehicle accident) with NACA 5 requiring more CPR and intubation (p < 0.001, p < 0.0005). The ROC AUC analysis showed the prehospital NACA and GCS values as the strongest variables predicting patients' survival.

CONCLUSIONS

This study provides valuable evidence supporting the effectiveness of the NACA score in assessing the severity of polytrauma patients in both the pre-ER and ER condition. Considering the statistical significant correlation with the GCS and with the ISS, NACA is a valid score for assessing polytrauma patients.

Base Deficit, International Normalized Ratio, and Glasgow Coma Scale (BIG) is a Predictor Tool for Survival and Mortality of Pediatric Trauma Patients

BACKGROUND

An accurate estimate of the survival and mortality at the initial trauma evaluation is essential to ensure appropriate triage and stratification of the patients for progressive care. One of the recognized tools for predicting mortality is the BIG Score, composed of admission base deficit, international normalized ratio (INR), and Glasgow Coma Scale (GCS). This study evaluates the BIG scale in predicting survival and mortality rates among pediatric trauma patients.

METHODS

Pediatric trauma patients, aged <18 years, visiting the emergency department of a tertiary hospital in the North of Jordan from 2014 to 2019 were included. Demographic data, trauma details, and lab results were collected. The BIG score for each patient was calculated. A receiver operator characteristic (ROC) curve was generated to determine the best suitable BIG cutoff point and its probabilities.

RESULTS

A total of 424 patients were included in this study. About two-thirds of the patients were males (n=298). The mean±SD of pH and GCS values were significantly lower among dead patients (6.0±2.5, 3.7±3.9, respectively) in comparison to alive ones (7.3±2.7, 11.5±5.5, respectively) (p=0.026, p<0.001, respectively). On the other hand, base deficit and INR values were significantly higher among dead patients (6.5±6.2, 1.9±2.5, respectively) than alive ones (1.9±3.6, 0.8±0.5, respectively), (p<0.001). The BIG score with a cutoff point of ≥10.0 has a high sensitivity (88.5%) and specificity (76.3%) for mortality prediction. The survival rate was correctly predicted in 100% of patients with a BIG score between 2.1 and 6. Also, the best survival predictions were seen in intubated patients (100%), followed by RTA-related trauma and ICU admission with decreasing frequency.

CONCLUSIONS

The current study has shown the added value of the BIG score as a simple and rapid tool to predict prognosis in pediatric trauma settings. The BIG score with a cutoff point of ≥10.0 is highly efficient in predicting pediatric trauma patients' mortality rates. However, the BIG score demonstrates greater accuracy in predicting survival outcomes compared to its ability to predict mortality among pediatric trauma patients.

Current Epidemiological Trends of Pediatric Traffic Accidents at a Romanian Clinical Hospital

BACKGROUND

Pediatric road traffic accidents (RTAs) have a substantial impact on the worldwide youth population, resulting in a considerable burden of disability. According to the World Health Organization's (WHO) Global Status Report on Road Safety, around 1.35 million children die each year in RTAs around the world, having a big effect on health and financial costs. Today's high-income countries like the Netherlands have experienced a decrease in the incidence of fatal traffic accidents (TAs) in children compared to countries with higher-than-average scores, including Romania, where roughly one out of every two minor deaths was a pedestrian; however, there is a lack of comprehensive and up-to-date epidemiological data on non-fatal TAs regarding pediatric patients. The objective of this study is to perform a thorough examination of the epidemiological aspects of Tas in pediatric patients admitted to the Emergency Department (ED) of "St. Mary's" Emergency Clinical Hospital for Children in Iasi, Romania.

MATERIALS AND METHODS

A descriptive retrospective research study was conducted at the "St. Mary's" Emergency Clinical Hospital for Children in Iasi, Romania, from January 2015 to December 2022. The research population includes all pediatric trauma patients that were between the age range of 1 month and 18 years who were treated by the trauma department. A total of 358 cases met the inclusion criteria and fulfilled fulfilled fulfilled. Data concerning variables such as accident incidents, types of injuries, and length of hospitalization have been gathered.

RESULTS

The average age of the patients was 11.43 ± 4.07 years, with patients of both sexes, the representation of the male sex being 78.5%. The incidence occurred during the summer, representing 15.3% in June. Of the patients admitted to the ED, 55.5% (n = 196) did not require surgery. Most of the patients spent from a minimum of one day to a maximum of 28 days in the hospital, with an average of 8.50 hospital days. The most common injuries were fractures (n = 221), and the most frequent anatomical region affected was the upper limbs (n = 55.2%).

CONCLUSION

While the literature on fatal TA cases shows a declining trend, there is a lack of up-to-date information on non-fatal TAs involving children. The results of our study suggest that there is a high incidence of pediatric TAs due to the scale of "St. Mary's" Emergency Clinical Hospital for Children, from Iasi, which provides medical services to a considerable number of patients coming from both rural and urban areas of the seven counties of Moldova region, in Romania.

Traffic Accidents in Children and Adolescents: A Complex Orthopedic and Medico-Legal Approach

Traffic accidents involving children and adolescents present complex challenges from both the medico-legal and orthopedic standpoints. Despite the implementation of road traffic safety laws, pediatric road traffic injuries continue to be a significant contributor to mortality rates, physical harm, and hospitalization on a global scale. For children and young people, automobile accidents are considered to be the primary culprit of mortality in developed nations. Even in highly developed nations, trauma is a significant factor in infant mortality. Each age category, from childhood to young adulthood, has its fracture patterns, as their skeletons are considerably different from those of adults. The consequences of traffic accidents extend beyond the immediate physical trauma. The medico-legal aspects surrounding these incidents add another layer of complexity, as legal repercussions may affect the responsible adult or parent, particularly in cases involving child fatalities. To effectively address traffic accidents in children and adolescents, a comprehensive approach is necessary. This approach should involve not only medical professionals but also legal experts and policymakers. Collaboration between orthopedic specialists, medico-legal professionals, law enforcement agencies, and relevant government bodies can facilitate the development and implementation of strategies aimed at prevention, education, the enforcement of traffic laws, and improved infrastructure. By addressing both the medical and legal aspects, it is possible to enhance road safety for children and adolescents, reducing the incidence of injuries and their associated long-term consequences. In this review, we aimed to summarize traffic accidents in children and adolescents from a complex orthopedic and medico-legal approach.

Outcomes of Pediatric Traumatic Cardiac Arrest: A 15-year Retrospective Study in a Tertiary Center in Saudi Arabia

BACKGROUND/OBJECTIVE

Traumatic cardiac arrest (TCA) is the cessation of cardiac pumping activity secondary to blunt or penetrating trauma. The aim of this study is to identify the outcomes of traumatic cardiac arrest in pediatric patients within the local community and report the causes and resuscitation management for the defined cases.

METHODS

This was a retrospectively conducted cohort study that took place in King Abdulaziz Medical City (KAMC) and King Abdullah Specialized Children Hospital (KASCH) from 2005 to 2021, Riyadh, Kingdom of Saudi Arabia. The study population involved pediatric patients aged 14 years or less who were admitted to our Emergency Department (ED) and had a traumatic cardiac arrest in the ED.

RESULTS

There were 26,510 trauma patients, and only 56 were eligible for inclusion. More than half (60.71%, n= 34) of the patients were males. Patients aged four years or less constituted 51.79% (n= 29) of the included cases. The majority of patients were Saudis (89.29%, n= 50). The majority of the patients had cardiac arrest prior to ED admission (78.57%, n= 44). The majority (89.29%, n= 50) had a GCS of 3 at ED arrival. The most frequently observed first cardiac arrest rhythm was asystole, followed by pulseless electrical activity and ventricular fibrillation, accounting for 74.55%, 23.64%, and 1.82%, respectively.

CONCLUSION

Pediatric TCA is high acuity. Children who experience TCA have dreadful outcomes, and survivors can suffer serious neurological impairments. We provided the experience of one of the largest trauma centers in Saudi Arabia to standardize the approach for managing TCA and, hopefully, improve its outcomes.

Characteristics and outcomes of pediatric blunt renal trauma: a nationwide cohort study in Japan

PURPOSE

The aim of this study was to describe epidemiologic features of pediatric blunt renal trauma.

METHODS

We performed a retrospective analysis using the Japan Trauma Data Bank over 15 years. We included patients younger than 18 years with blunt renal trauma. We analyzed temporal trends and variations across age groups in patient characteristics, intervention, and in-hospital mortality. We also assessed factors associated with in-hospital mortality.

RESULTS

We identified 435 pediatric patients with blunt renal trauma. Their median age was 14 years and median Injury Severity Score (ISS) was 17. The most common mechanism of injury was traffic accident in all age groups. Nephrectomy was performed in 3.2%, and the overall in-hospital mortality was 4.6%, both of which showed decreasing trends. The most common mechanism of injury by age group was a pedestrian accident in infants/toddlers/preschoolers (43.5%), pedestrian accident in middle childhood (18.5%), bicycle accident in young teens (24.7%), and motorcycle accident in teenagers (41.2%). Sports-related injury was common in young teens (23.3%) and teenagers (15.2%). Factors such as ISS, shock, concomitant injury, and nephrectomy were associated with high in-hospital mortality.

CONCLUSIONS

We described decreasing trends in nephrectomy and in-hospital mortality in pediatric blunt renal trauma and found traffic accident and sports-related injury were common in the pediatric population in Japan.

Effect of under triage on early mortality after major pediatric trauma: a registry-based propensity score matching analysis

Background

Little is known about the effect of under triage on early mortality in trauma in a pediatric population. Our objective is to describe the effect of under triage on 24-h mortality after major pediatric trauma in a regional trauma system.

Methods

This cohort study was conducted from January 2009 to December 2017. Data were obtained from the registry of the Northern French Alps Trauma System. The network guidelines triage pediatric trauma patients according to an algorithm shared with adult patients. Under triage was defined by the number of pediatric trauma patients that required specialized trauma care transported to a non-level I pediatric trauma center on the total number of injured patients with critical resource use. The effect of under triage on 24-h mortality was assessed with inverse probability treatment weighting (IPTW) and a propensity score (Ps) matching analysis.

Results

A total of 1143 pediatric patients were included (mean [SD], age 10 [5] years), mainly after a blunt trauma (1130 [99%]). Of the children, 402 (35%) had an ISS higher than 15 and 547 (48%) required specialized trauma care. Nineteen (1.7%) patients died within 24 h. Under triage rate was 33% based on the need of specialized trauma care. Under triage of children requiring specialized trauma care increased the risk of death in IPTW (risk difference 6.0 [95% CI 1.3–10.7]) and Ps matching analyses (risk difference 3.1 [95% CI 0.8–5.4]).

Conclusions

In a regional inclusive trauma system, under triage increased the risk of early death after pediatric major trauma.

Trauma Scores and Their Prognostic Value for the Outcome Following Pediatric Polytrauma

Purpose: The management and prognostic assessment of pediatric polytrauma patients can pose substantial challenges. Trauma scores developed for adults are not universally applicable in children. An accurate prediction of the severity of trauma and correct assessment of the necessity of surgical procedures are important for optimal treatment. Several trauma scores are currently available, but the advantages and drawbacks for use in pediatric patients are unclear. This study examines the value of the trauma scores Injury Severity Score (ISS), Pediatric Trauma Score (PTS), National Advisory Committee for Aeronautics (NACA), and Glasgow Coma Score (GCS) for the assessment of the polytraumatized child. Methods: In a retrospective study, 97 patients aged 0-17 years who presented with polytrauma and an ISS ≥16 in the trauma bay were included in the study. Patient records including radiological studies were analyzed. Pathological imaging findings and emergency surgery were assessed as outcome variables and the predictive value of the trauma scores were analyzed using receiver operator characteristic (ROC) curves. Statistical significance was set at an alpha level of P ≤ 0.05. Results: In this study, 35 of the 97 studied children had pathological cranial computed findings. These either underwent craniectomy or trepanation or a parenchymal catheter was placed for intracranial pressure monitoring. Abdominal trauma was present in 45 patients, 16 of which were treated surgically. Forty-three patients arrived with thoracic injuries, 10 of which received a thoracic drainage. One child underwent an emergency thoracotomy. Predictive accuracy for emergency surgery calculated using receiver-operator characteristic (ROC) curves was highest for ISS and NACA scores (0,732 and 0.683, respectively), and lower for GCS (0.246) and PTS (0.261). Conclusion: In our study cohort, initial ISS and NACA scores better predicted operative interventions and outcome than PTS or GCS for polytraumatized pediatric patients.

Pelvic fractures in children (pelvic ring and acetabulum)

Pelvic fractures in children are rare and often the result of high-energy trauma. The possibility of associated lesions cannot be ignored. Treatment at a specialized children's hospital is a must. The multidisciplinary care team must include a paediatric orthopaedic surgeon. In the emergency room, the surgeon contributes to haemodynamic stabilization of the child by reducing and stabilizing posterior arch fractures and restoring the skeletal cohesion to make it easier to move the child and allow other examinations to be performed. Imaging modalities are used to determine the stability of the pelvic ring fracture, the risk of epiphysiodesis of an acetabulum fracture if the triradiate cartilage is open and the joint congruency if the triradiate cartilage is closed. Internal fixation can be used if surgery is being performed for associated non-orthopaedic injuries. Most vertically stable fractures are treated non-surgically. Fractures that are unstable vertically will require surgical treatment. Treatment of acetabulum fractures depends on the status of the triradiate cartilage. In older children, it is similar to the treatments used in adults. In children with open growth plates, the goal is to make sure the acetabulum continues growing. In all cases, the patients must be instructed to start physical therapy as soon as possible. Full recovery can be expected after stable pelvic fractures. Unstable pelvic fractures can lead to sequelae, the severity of which depend on the residual pelvic displacement and involvement of the growth plates that can cause epiphysiodesis. Surgery to correct these deformities is challenging. The most serious occur when the vertical displacement of the hemipelvis must be corrected. After an acetabulum fracture, removal of the growth blocker can be done in children under 10 years of age. In older children, acetabular dysplasia requires periacetabular osteotomy.

[Thoracic injuries in severely injured children : Association with increased injury severity and a higher number of complications]

BACKGROUND

Severely injured children and adolescents in clinical practice are rare. For adequate treatment of these patients, detailed knowledge of anatomical and physiological peculiarities, as well as abundant injury patterns, are indispensable. Traumatic brain injuries are known to lead to an unfavorable outcome. In addition, thoracic trauma is regarded as prognostically unfavorable.

OBJECTIVES

This study depicts epidemiology and injury patterns of severely injured children and adolescents focusing on peculiarities in the severely injured with associated thoracic injuries.

MATERIALS AND METHODS

A retrospective analysis of underaged patients with suspicion of severe injuries who obtained emergency-room treatment in our level-one trauma center during a four-year time period was performed. The data was collected prospectively using the TraumaRegister® of the German Trauma Society as well as an extended house-internal dataset including data of daily clinical routine. The patients were divided into subgroups with (TT) and without (KT) thoracic trauma based on whether a thoracic injury was present or not. For further analysis, four age groups were established.

RESULTS

In all, 256 patients younger than 18 years were eligible. Of these, 46 patients revealed thoracic injuries. The mean age of patients with thoracic trauma (12.4 ± 4.9 years) was significantly higher than for patients without thoracic trauma (8.0 ± 5.2 years). In both subgroups, most patients were male (TT: 69.9%, KT: 64.8%). Patients with concomitant thoracic trauma showed a significantly higher injury severity score (ISS) than patients without thoracic trauma (ISS: TT: 26.7 ± 15.8 vs. KT: 8.1 ± 6.8 points). Mortality was higher for TT as well (TT: 6.9% vs. KT: 1.9%). For both groups, traffic accidents were the most common cause of injury. Of patients with thoracic injuries, 52.2% developed at least one complication during their hospital stay (KT: 12.9%).

CONCLUSIONS

Thoracic trauma is a relevant factor in children with regard to the severity of total injury and complications. Particular attention should therefore be paid to early diagnosis and treatment.

Anatomic, diagnostic and management challenges in paediatric pelvic injuries: a review

Pelvic injuries have an incidence of 1: 100 000 children per year in the UK, of which 10% are unstable. A literature review was conducted. Clinical examination alone in a stable patient precludes the need for imaging. Imaging options in the acute pelvic injury are critically reviewed. Where appropriate Judet views or limited exposure computed tomography scan remain of diagnostic benefit. Displacement greater than 1 cm should be reduced and held with an appropriate method. Closed reduction and external fixation for rotationally unstable fractures, and closed or open reduction with internal fixation of two columns should be considered for rotationally and vertically unstable fractures.

Paediatric traumatic cardiac arrest: the development of an algorithm to guide recognition, management and decisions to terminate resuscitation

INTRODUCTION

Paediatric traumatic cardiac arrest (TCA) is a high acuity, low frequency event. Traditionally, survival from TCA has been reported as low, with some believing resuscitation is futile. Within the adult population, there is growing evidence to suggest that with early and aggressive correction of reversible causes, survival from TCA may be comparable with that seen from medical out-of-hospital cardiac arrests. Key to this survival has been the adoption of a standardised approach to resuscitation. The aim of this study was, by a process of consensus, to develop an algorithm for the management of paediatric TCA for adoption in the UK.

METHODS

A modified consensus development meeting of UK experts involved in the management of paediatric TCA was held. Statements discussed at the meeting were drawn from those that did not reach consensus (positive/negative) from a linked three-round online Delphi study. 19 statements relating to the diagnosis, management and futility of paediatric TCA were initially discussed in small groups before each participant anonymously recorded their agreement with the statement using 'yes', 'no' or 'don't know'. In keeping with our Delphi study, consensus was set a priori at 70%. Statements reaching consensus were included in the proposed algorithm.

RESULTS

41 participants attended the meeting. Of the 19 statements discussed, 13 reached positive consensus and were included in the algorithm. A single statement regarding initial rescue breaths reached negative consensus and was excluded. Consensus was not reached for five statements, including the use of vasopressors and thoracotomy for haemorrhage control in blunt trauma.

CONCLUSION

In attempt to standardise our approach to the management of paediatric TCA and to improve outcomes, we present the first consensus-based algorithm specific to the paediatric population. While this algorithm was developed for adoption in the UK, it may be applicable to similar healthcare systems internationally.

Management of Orthopaedic Injuries in Multiply Injured Child

Multiply injured child is a unique challenge to the medical communities worldwide. It is a leading cause of preventable mortality and morbidity in children. Common skeletal injuries include closed or open fractures of tibia and femur and pelvic injuries. Initial management focuses on saving life and then saving limb as per pediatric advanced life support and advanced trauma life support. Orthopedic management of open fracture includes splinting the limb, administration of prophylactic antibiotic, and surgical debridement of the wound when safe. However, gross contamination, compartment syndrome, and vascular injuries demand urgent attention.

Anatomical and Physiological Differences between Children and Adults Relevant to Traumatic Brain Injury and the Implications for Clinical Assessment and Care

General and central nervous system anatomy and physiology in children is different to that of adults and this is relevant to traumatic brain injury (TBI) and spinal cord injury. The controversies and uncertainties in adult neurotrauma are magnified by these differences, the lack of normative data for children, the scarcity of pediatric studies, and inappropriate generalization from adult studies. Cerebral metabolism develops rapidly in the early years, driven by cortical development, synaptogenesis, and rapid myelination, followed by equally dramatic changes in baseline and stimulated cerebral blood flow. Therefore, adult values for cerebral hemodynamics do not apply to children, and children cannot be easily approached as a homogenous group, especially given the marked changes between birth and age 8. Their cranial and spinal anatomy undergoes many changes, from the presence and disappearance of the fontanels, the presence and closure of cranial sutures, the thickness and pliability of the cranium, anatomy of the vertebra, and the maturity of the cervical ligaments and muscles. Moreover, their systemic anatomy changes over time. The head is relatively large in young children, the airway is easily compromised, the chest is poorly protected, the abdominal organs are large. Physiology changes—blood volume is small by comparison, hypothermia develops easily, intracranial pressure (ICP) is lower, and blood pressure normograms are considerably different at different ages, with potentially important implications for cerebral perfusion pressure (CPP) thresholds. Mechanisms and pathologies also differ—diffuse injuries are common in accidental injury, and growing fractures, non-accidental injury and spinal cord injury without radiographic abnormality are unique to the pediatric population. Despite these clear differences and the vulnerability of children, the amount of pediatric-specific data in TBI is surprisingly weak. There are no robust guidelines for even basics aspects of care in children, such as ICP and CPP management. This is particularly alarming given that TBI is a leading cause of death in children. To address this, there is an urgent need for pediatric-specific clinical research. If this goal is to be achieved, any clinician or researcher interested in pediatric neurotrauma must be familiar with its unique pathophysiological characteristics.

The Role of Pelvic Packing for Hemodynamically Unstable Pelvic Ring Injuries

In patients with severe pelvic fractures, exsanguinating hemorrhage represents the major cause of death within the first 24 hours. Recently, multiple management algorithms have been proposed; however, the optimal treatment modalities, in particular, in the hemodynamically unstable patient with pelvic fracture are still a matter of debate. Mechanical pelvic stabilization by pelvic binder, anterior external fixator, and/or pelvic C-clamp constitutes the first treatment option in the hemodynamically unstable patient with pelvic fractures. The mechanically stabilized pelvic ring provides the basis for pelvic packing through a minimal extraperitoneal approach, which effectively controls venous bleeding and bleeding from the fractured bony surface. Patients with persistent hypotension and/or transfusion requirements should undergo angiography and selective embolization for definitive arterial control if necessary. This review article describes the current trend in the initial management of patients with pelvic fractures and hemodynamic instability, and focuses on the role of pelvic packing.

Diagnostic imaging in pediatric polytrauma management

Trauma is the cause of over 45% of deaths in children aged 1 to 14 years. Since multiple injuries are common among children, the emergency physician has to assess all the organs of a high-energy injured child, independent of mechanism of the trauma. Even if the principles of polytrauma management are identical both in children and in adults, the optimal pediatric patient care requires a specific understanding of some important anatomical, physiological, and psychological differences that play a significant role in the assessment and management of a pediatric patient. Emergency Radiology already plays a crucial role in the diagnostic process of a polytraumatized child according to the primary survey, through the use of multiple imaging modalities. Radiological and Ultrasound examinations play a basic role in the hemodynamically unstable patients. In the hemodynamically stable patients whole-body CT scanning is the most immediate radiological procedure that allows the examination of all the body parts of a polytraumatized child, reducing the number of minor injuries that might otherwise be neglected.

Scoring systems of severity in patients with multiple trauma

Trauma is a major cause of morbidity and mortality; hence severity scales are important adjuncts to trauma care in order to characterize the nature and extent of injury. Trauma scoring models can assist with triage and help in evaluation and prediction of prognosis in order to organise and improve trauma systems. Given the wide variety of scoring instruments available to assess the injured patient, it is imperative that the choice of the severity score accurately match the application. Even though trauma scores are not the key elements of trauma treatment, they are however, an essential part of improvement in triage decisions and in identifying patients with unexpected outcomes. This article provides the reader with a compendium of trauma severity scales along with their predicted death rate calculation, which can be adopted in order to improve decision making, trauma care, research and in comparative analyses in quality assessment.

Management of Bleeding Pelvic Fractures

INTRODUCTION

In patients with severe pelvic fractures, exsanguinating hemorrhage represents the major cause of death within the first 24 h. Despite advances in management, the mortality rate in these patients remains significantly high. Recently, multiple treatment algorithms have been proposed for patients with severe pelvic fractures; however, the optimal modalities in particular in the hemodynamically unstable patient are still a matter of lively debate.This review article focuses on the recent body of knowledge on the different treatment options in patients with severe pelvic fractures and proposes the possible role of each modality in the management of these patients.

METHODS

The MEDLINE database was searched for medical literature addressing the management of severe pelvic fractures with specific attention given to recent, clinically relevant publications.

RESULTS

Angiography and embolization have emerged as excellent methods for addressing arterial bleeding. Mechanical pelvic stabilization and surgical hemostasis by pelvic packing, on the other hand, may effectively control venous bleeding and bleeding from the fractured bony surface. However, since there is no precise way to determine the major source of bleeding that is responsible for the hemodynamic instability, controversy remains over the timing and optimal order of angiography, mechanical pelvic stabilization, and packing.

CONCLUSIONS

The author's own approach to these patients includes angiographic embolization as a first-line treatment only in hemodynamically stable patients with an arterial blush seen in the computed tomography scan, indicating acute arterial bleeding. Hemodynamically unstable patients are immediately transferred to the operating room, where pelvic packing and mechanical stabilization of the pelvic ring are carried out. Optionally, a subsequent postoperative angio-embolization is performed if signs of further bleeding remain present.

F. A case study involving a blunt abdominal trauma leading to disruption of the aortic bifurcation in an infant

The incidence of aortic disruption secondary to blunt abdominal trauma is rarely reported in the pediatric population. In general, most of the cases described are the result of motor vehicle accidents. We report on the treatment and outcomes of a 5-year-old child with aortic bifurcation disruption secondary to an unusual case of blunt abdominal trauma who was admitted to the emergency room in hypovolemic shock and subjected to immediate exploratory laparotomy and vascular repair. The mechanical forces involved in aortic disruption and the management options for repair and treatment of this injury will be discussed.

Update on the definition of polytrauma

PURPOSE

The definition and use of the term "polytrauma" is inconsistent and lacks validation. This article describes the historical evolution of the term and geographical differences in its meaning, examines the challenges faced in defining it adequately in the current context, and summarizes where the international consensus process is heading, in order to provide the trauma community with a validated and universally agreed upon definition of polytrauma.

CONCLUSION

A lack of consensus in the definition of "polytrauma" was apparent. According to the international consensus opinion, both anatomical and physiological parameters should be included in the definition of polytrauma. An Abbreviated Injury Scale (AIS) based anatomical definition is the most practical and feasible given the ubiquitous use of the system. Convincing preliminary data show that two body regions with AIS >2 is a good marker of polytrauma-better than other ISS cutoffs, which could also indicate monotrauma. The selection of the most accurate physiological parameters is still underway, but they will most likely be descriptors of tissue hypoxia and coagulopathy.

Aortic bifurcation rupture after blunt abdominal trauma in a child: a case report

Blunt trauma to the abdomen resulting in aortic injury is rare in children with only a few case reports in the past 40 years. We describe the diagnosis and management of a 2-year-old boy who survived an aortic bifurcation rupture after blunt trauma.

[Fracture stabilization in polytraumatized children]

Polytrauma is a rare diagnosis in childhood. Even after high-energy accidents isolated injuries of the skull and brain or extremities are more common. Injury is still the most frequent cause of death in childhood in industrialized countries. The lethality of polytraumatized children is about 19%. Injuries of the extremities do not play such an important role for the survival of polytraumatized children but for the definitive outcome. The diagnostic algorithm for polytraumatized children is related to adults and includes spiral computed tomography in the emergency room. Plain radiographs are still the gold standard for the diagnostic workup of fractures. Generally therapeutic approaches in the treatment of fractures in children are often conservative. Because of the special situation in polytrauma with ICU care and the need for venous catheters, fast mobilization and positioning in bed, indications for operative treatment and definitive stabilization of fractures are required for polytraumatized children.
