Population-based study of paediatric head injury

AIM: There is a paucity of population-based studies regarding the spectrum of paediatric head injury from mild through serious to fatal paediatric head injury. The aims of the present study were to determine the incidence, demographics and outcome of significant head injury in a state-wide population of children aged 0-15 years. A secondary aim was to determine if any serious head injuries were being missed under the current management protocols of the state-wide trauma system. METHODS: A retrospective review of significant head injury in all paediatric patients over a period of 2 years was undertaken. Data were collected from the Victorian State Trauma Outcome Registry and Monitoring database, the Victorian Emergency Minimum Dataset and from the Victorian Institute of Forensic Medicine. RESULTS: The incidence of paediatric head injury in Victoria over the 2-year period was 765 per 100000 per year. The incidence of admitted head injuries was 75 per 100000 per year and the incidence of significant head injury was seven per 100000 or 151 children. Forty-one per cent of these injuries required surgical intervention. Mortality was 1.6 children per 100000. All patients who died presented with a Glasgow Coma Score (GCS) of 3 and had multiple other risk factors. There were no deaths in patients discharged from hospital. Demographic and clinical factors associated with higher mortality and morbidity was determined. CONCLUSION: The incidence of significant paediatric head injury was low. Deaths occurred early and were always associated with significant early clinical features of severe head injury. This highlights the importance of strategies for the prevention of head injuries. There appeared to be no serious head injuries missed during the study period.     

Pediatric Trauma Care: An Ongoing Evolution

Trauma remains the leading cause of death and disability in children despite considerable advances in the treatment of injury in the pediatric population. As we move forward into the 21st century, the challenge will be to develop and implement appropriate triage systems to ensure that severely injured children will be treated at centers with a commitment to their care. Issues of overtriage and undertriage need to be addressed, so that the limited resource of PTCs is not overwhelmed by less severely injured patients or conversely, that the definitive management of severe injuries is not delayed by lengthy periods of evaluation at centers ill equipped to care for injured children. PTCs need to take the lead in the development of such integrated pediatric trauma systems. Finally, the importance of injury prevention strategies needs to be emphasized. The vast majority of injuries in children are potentially preventable. Institutions and individuals with a commitment to the care of those injured must also work toward the prevention of the problem in the first place through a combination of research, education, and advocacy. As those who work in the trauma field know, injury is no accident.     

Predictors of intracranial injuries in children after blunt head trauma

This study was conducted to determine if clinical features can predict the risk of intracranial injury (ICI) in pediatric closed head trauma. We enrolled 3,806 children under 16 years consecutively referred for acute closed head trauma to the paediatric emergency room of five Italian children’s hospitals. Relevant outcomes were death and diagnosis of ICI. Clinical symptoms and signs were evaluated as possible outcome predictors. Children were also classified into five groups according to their clinical presentation. The association of ICI with signs and symptoms and the appropriateness of the five-group classification in predicting the likelihood of ICI were evaluated by logistic regression analyses. ICI was diagnosed in 22 children; 2 of them died. The risk of fatal and nonfatal ICI was 0.5 and 5.2 per 1,000 children with closed head trauma respectively. Significant associations were found between ICI and loss of consciousness, prolonged headache, persistent drowsiness, abnormal mental status, focal neurological signs, signs of skull fracture in non-frontal areas and signs of basal skull fracture. The five-group classification of children allowed an excellent prediction in terms of likelihood of ICI (ROC area 0.972). Conclusions: Selection of children with closed head trauma based on different combinations of signs and symptoms allows for early identification of subjects at different risk for ICI. In patients with minor head injuries, the absence of loss of consciousness, drowsiness, amnesia, prolonged headache, clinical evidence of basal or non-frontal skull fracture identified 100% of children without lesions. Validation of our results with a larger sample of patients with ICI would be highly desirable.     

Penetrating injuries in children: Is there a message?

OBJECTIVES: To determine the frequency, management and outcome of penetrating trauma in children. METHODS: A retrospective review of penetrating injuries in children under 16 years of age admitted to the Children's Hospital at Westmead (CHW), and deaths reported to the New South Wales Paediatric Trauma Death (NPTD) Registry, from January 1988 to December 2000. Patient details, circumstances of trauma, injuries identified, management and outcome were recorded. RESULTS: Thirty-four children were admitted to the CHW with penetrating injuries during the 13-year period. This represented 0.2% of all trauma admissions, but 3% of those children with major trauma. The injury typically involved a male, school-age child that fell onto a sharp object or was assaulted with a knife or firearm by a parent or person known to them. Twenty-five children (75%) required operative intervention for their injuries and 14 survivors (42%) suffered long-term morbidity. Thirty children were reported to the NPTD Registry over the same interval, accounting for 2.3% of all trauma deaths in New South Wales. Of these, a significant minority was injured by falls from a mower or a tractor towing a machine with blades. CONCLUSIONS: Penetrating injuries are uncommon, but cause serious injury in children. There are two clear groups: (i) those dead at the scene or moribund on arrival, in whom prevention must be the main aim; and (ii) those with stable vital signs. Penetrating wounds should be explored in the operating theatre to exclude major injury. Young children should not ride on mowers or tractors.     

The imaging of paediatric thoracic trauma

Major chest trauma in a child is associated with significant morbidity and mortality. It is most frequently encountered within the context of multisystem injury following high-energy trauma such as a motor vehicle accident. The anatomic-physiologic make-up of children is such that the pattern of ensuing injuries differs from that in their adult counterparts. Pulmonary contusion, pneumothorax, haemothorax and rib fractures are most commonly encountered. Although clinically more serious and potentially life threatening, tracheobronchial tear, aortic rupture and cardiac injuries are seldom observed. The most appropriate imaging algorithm is one tailored to the individual child and is guided by the nature of the traumatic event as well as clinical parameters. Chest radiography remains the first and most important imaging tool in paediatric chest trauma and should be supplemented with US and CT as indicated. Multidetector CT allows for the accurate diagnosis of most traumatic injuries, but should be only used in selected cases as its routine use in all paediatric patients would result in an unacceptably high radiation exposure to a large number of patients without proven clinical benefit. When CT is used, appropriate modifications should be incorporated so as to minimize the radiation dose to the patient whilst preserving diagnostic integrity.     

Somatosensory evoked potentials in children with severe head trauma

We evaluated the predictive value of somatosensory evoked potentials (SEP) in a series of children with severe traumatic brain injury (TBI). The prospective clinical investigation was performed in a Level I paediatric trauma centre. We included 26 consecutive comatose paediatric patients aged from 1 month to 17 years (median age 11 years) following severe TBI (initial Glasgow Coma Score (GCS) 8 or below). Besides SEP recordings, the intracranial pressure and the results of an initial cranial CT scan were filed. The Glasgow Outcome Scale (GOS) was used to assess outcome at discharge. Thirteen children had normal SEP measurements, three patients had abnormal SEP recordings and a cortical response was bilaterally absent in ten children. Out of 26 children, 10 died whereas two remained in a persistent vegetative state. Only one child suffered from significant neurological deficits (GOS 3) at discharge. Seven patients survived with a GOS of 4 and six children survived without neurological impairment (GOS 5). Normal SEP indicated a favourable outcome in most children but did not rule out the occurrence of death, while absence of SEP was related to unfavourable outcome in all cases. Conclusion: Measurement of somatosensory evoked potentials provides valuable data for determining the prognosis at early coma stages. Our data show that an unfavourable outcome can be predicted with higher precision than a favourable outcome.     

Severe injury mechanisms in two paediatric trauma centres: Determination of prevention priorities

BACKGROUND

To meet community needs, injury prevention programs for children should be targeted to trends in objective data on mechanisms of injury. The aim of the present study was to identify the most important severe injury mechanisms.

METHODS

The present study retrospectively reviewed severe paediatric trauma patients in two regional trauma centres. Injury prevention priority scores were computed using different severity measures – injury severity score (ISS), revised trauma score, trauma-related injury severity score, Glasgow Coma Scale (GCS) and mortality – to identify prevention priorities.

RESULTS

A total of 3732 children with severe injury were identified; mean age (±SD) was 9.0±5.2 years and 2469 (66.2%) were boys. The GCS was 7 or lower in 209 patients (5.6%) and the median ISS was 9. Overall, there were 77 deaths (2.1%). ‘Fall from height’ was the most frequent mechanism of injury, and ‘motor vehicle traffic injury’ resulted in the most severe injury. The most significant mechanisms of injury, using ISS, were ‘fall from height’, ‘motor vehicle traffic injury’, ‘pedestrian struck by motor vehicle’, ‘bicycle injuries’ and ‘child abuse’. Different priorities were identified depending on the severity measures used – ‘fall from height’ would be the priority with ISS, revised trauma score and trauma-related injury severity score; ‘motor vehicle traffic injury’ with mortality and ‘drowning/submersion’ with GCS. ‘Fall from height’ was the highest ranked mechanism of injury in one centre compared with ‘motor vehicle traffic injury’ in the other. Younger children tended to have injuries as a result of falls, while adolescents had more motor vehicle occupant injuries. Failure to use safety devices, such as helmets and seat belts, was a common finding among severely injured children.

CONCLUSION

The present study shows that the severe injury prevention priorities identified vary depending on the severity measures used. The variations seen across age groups and between the two centres are also important factors that must be taken into account when developing prevention programs or considering research initiatives.     

Childhood injury prevention: Where we've been and where we need to be

Injury remains the leading cause of death for children and adolescents in the US, and firearm injury has overtaken motor-vehicle crashes as the leading mechanism in the US since the topic of injury prevention was last reviewed in this journal. The success of injury prevention efforts relies on multidisciplinary collaboration, and pediatric surgeons play a central role as clinicians who provide and coordinate the care for injured children, as trauma program leaders, and as advocates for children's health and safety. This review will provide a concise history of injury prevention in the US and highlights three areas where pediatric surgeons have an opportunity to impart impactful change in their communities that could lead to lower injury rates.     

Imaging of accidental paediatric head trauma

Head trauma is the most common form of injury sustained in serious childhood trauma and remains one of the top three causes of death despite improved road planning and safety laws. CT remains the first-line investigation for paediatric head trauma, although MRI may be more sensitive at picking up the full extent of injuries and may be useful for prognosis. Follow-up imaging should be tailored to answer the specific clinical question and to look for possible complications.     

Childhood injuries in an urban area of Ghana A hospital-based study of 677 cases

To the best of our knowledge, there has not been any recent available study of trauma-related hospitalisation of paediatric patients in an urban area of the sub-Saharan countries. Accidental injury, especially among children, has become one of the most serious major health problems facing developing countries, including those in sub-Saharan Africa. We reviewed 677 children admitted to the Komfo Anokye Teaching Hospital in Kumasi, Ghana, from August 1995 to July 1996 to elicit the incidence of various injuries, causes, rates of injury, and survival of children aged 0 to 14 years who had sustained trauma during this period. The most common mechanisms of injury were pedestrian knockdowns (40.0%), falls (27.2%), and burns (17.6%). The annual rate of injury was 230/100 000 children. Boys sustained higher injury rates in all age groups than girls, with an overall rate of, 136/100 000 children as compared to 92/100 000 for girls. Rates of injury were higher for children over 5 years of age in six of the seven specific causes of injury studied. When analysing the region of principal injury, for severe injuries (abbreviated injury scale 3–5) the extremities suffered most, followed by the skin and head. There was increased mortality for patients with an injury severity score >20. The overall mortality for this study was 5.5%. There is, therefore, a need to establish prevention priorities and to design effective prevention strategies for children of school-going age, who are most at risk of sustaining trauma.

Polytrauma in children

Polytrauma in children is rare, yet trauma is a leading cause of death in children. Clinicians with responsibility for the management of children suffering major trauma must recognise the conflict between these facts. Simulation and preparation can help to improve the quality of care at both individual and institutional levels. Children are not small adults, and their anatomic and physiological differences manifest themselves in different responses to major trauma than those seen in adults. This reality should be met with a tailored approach to assessment, investigation and management that accommodates the changes occurring from infancy, through childhood and adolescence to adulthood. This approach minimizes the risk of harm from inappropriate irradiation or intervention. Children have remarkable resilience and can make dramatic recoveries from seemingly irrecoverable situations. The appropriate treatment of musculoskeletal injuries should therefore not be compromised in the setting of polytrauma, and attention must be given to the optimal time for treatment. Damage control resuscitation and early appropriate care facilitate an individualised response. Outcomes for paediatric polytrauma are improved by management in a specialist centre, with early aggressive management of injuries that require surgical treatment by an experienced multidisciplinary team.     

Blunt abdominal trauma in children

Blunt abdominal trauma is the commonest cause of intra-abdominal injuries in children. The use of computerized axial tomography and non-operative management of haemoperitoneum are two significant developments in the last two decades in the management of blunt abdominal trauma in children. The concept of non-operative management was introduced in late 1979 and wherever possible remains the optimum treatment. Computerized tomography scan for paediatric abdominal trauma was first described in 1980 and remains the investigation of choice. There is no substitute, however, for a good history, astute physical examination, and strict adherence to the principles of primary and secondary survey, prompt resuscitation, vigilant monitoring and repeated evaluation.     

Practitioner Review: Beyond shaken baby syndrome: what influences the outcomes for infants following traumatic brain injury?

Background: Traumatic brain injury (TBI) in infancy is relatively common, and is likely to lead to poorer outcomes than injuries sustained later in childhood. While the headlines have been grabbed by infant TBI caused by abuse, often known as shaken baby syndrome, the evidence base for how to support children following TBI in infancy is thin. These children are likely to benefit from ongoing assessment and intervention, because brain injuries sustained in the first year of life can influence development in different ways over many years. Methods: A literature search was conducted and drawn together into a review aimed at informing practitioners working with children who had a brain injury in infancy. As there are so few evidence‐based studies specifically looking at children who have sustained a TBI in infancy, ideas are drawn from a range of studies, including different age ranges and difficulties other than traumatic brain injury. Results: This paper outlines the issues around measuring outcomes for children following TBI in the first year of life. An explanation of outcomes which are more likely for children following TBI in infancy is provided, in the areas of mortality; convulsions; endocrine problems; sensory and motor skills; cognitive processing; language; academic attainments; executive functions; and psychosocial difficulties. The key factors influencing these outcomes are then set out, including severity of injury; pre‐morbid situation; genetics; family factors and interventions. Conclusions: Practitioners need to take a long‐term, developmental view when assessing, understanding and supporting children who have sustained a TBI in their first year of life. The literature suggests some interventions which may be useful in prevention, acute care and longer‐term rehabilitation, and further research is needed to assess their effectiveness.     

A prospective study into the demographics and treatment of paediatric facial lacerations

To evaluate the demographics and treatment of facial lacerations occurring in a paediatric patient cohort. We undertook a prospective study of 106 children who sustained a soft tissue facial injury and who presented to an Accident and Emergency department in a UK district general hospital supporting a population of 750,000. Approximately 31,000 are dependent children between the age of 0–12 years. Our results show that the majority of paediatric patients who sustained a facial laceration were male (62%). The frequency of this injury was greatest amongst males across all age groups. The majority of children above 3 years of age sustained their injury outdoors. The peak time for injury varied for different age groups. The 0–3 year olds sustained the highest incidence of injuries around 17:00 h. A bi-modal time pattern was seen in the 4–6 year age group, initially at 12:00 h with a second peak at 17:00 h. The most frequent aetiology was play. A significant finding was that 8% of the injuries that were managed resulted from a dog bite. Almost 50% of children above 4 years of age, who required primary closure of their laceration, were able to tolerate their treatment being performed under local anaesthesia. The pattern of facial lacerations in our study supports the results of previous studies. Our data has provided further insight into the presentation of these injuries. These studies are valuable in targeted injury prevention programmes aimed at potentially reducing the nature, incidence and severity of facial soft tissue trauma in children in the UK.     

Prevalence, comorbidity and course of trauma reactions in young burn-injured children

Background: Infants, toddlers and preschoolers are the highest risk group for burn injury. However, to date this population has been largely neglected. This study examined the prevalence, onset, comorbidity and recovery patterns of posttrauma reactions in young children with burns. Methods: Parents of 130 unintentionally burned children (1–6 years) participated in the study. The Diagnostic Infant Preschool Assessment was conducted with parents at 1 and 6 months postinjury. Results: The majority of children were resilient. However, 35% were diagnosed with at least one psychological disorder, there was a high rate of comorbidity with posttraumatic stress disorder, and 8% of children did not experience recovery in distress levels over the course of 6 months. Conclusions: These outcomes are likely to have serious repercussions for a young child’s medical and psychosocial recovery as well as their normal developmental trajectories. It is recommended that screening, prevention and early intervention resources are incorporated into paediatric health care settings to optimise children’s psychological adjustment following burn injury.     

The management of epidural haematomas — surgical versus conservative treatment

We treated 14 children and infants during 1990–1993 who suffered severe head trauma with consequent epidural haematomas. We tried, in accordance with several recent publications, to follow part of them conservatively. The report describes the clinical and radiological features of these patients and discusses the criteria for conservative management of epidural haematoma in paediatric patients. The relevant literature is reviewed     

Patterns and risks in spinal trauma.

BACKGROUND: Spinal injury in children is rare, and poses many difficulties in management. AIMS: To ascertain the prevalence of spinal injury within the paediatric trauma population, and to assess relative risks of spinal injury according to age, conscious level, injury severity score (ISS), and associated injuries. METHODS: Spine injured children were identified from the UK Trauma Audit & Research Network Database from 1989 to 2000. Relative risks of injury were calculated against the denominator paediatric trauma population. RESULTS: Of 19 538 on the database, 527 (2.7%) suffered spinal column fracture/dislocation without cord injury and 109 had cord injury (0.56% of all children; 16.5% of spine injured children). Thirty children (0.15% of all children; 4.5% of spine injured children) sustained spinal cord injury without radiological abnormality (SCIWORA). Cord injury and SCIWORA occurred more commonly in children aged < or =8. The risk of spine fracture/dislocation without cord injury was increased with an ISS >25 and with chest injuries. The risk of cord injury was increased with reduced GCS, head injury, and chest injury. CONCLUSIONS: Spinal cord injury and SCIWORA occur more frequently in young children. Multiple injuries and chest injuries increase the risk of fracture/dislocation and of cord injury. Reduced GCS and head injuries increase the risk of cord injury.     

Pediatric blunt splenic trauma: a comprehensive review

Abdominal trauma is a leading cause of death in children older than 1 year of age. The spleen is the most common organ injured following blunt abdominal trauma. Pediatric trauma patients present unique clinical challenges as compared to adults, including different mechanisms of injury, physiologic responses, and indications for operative versus nonoperative management. Splenic salvage techniques and nonoperative approaches are preferred to splenectomy in order to decrease perioperative risks, transfusion needs, duration/cost of hospitalization, and risk of overwhelming postsplenectomy infection. Early and accurate detection of splenic injury is critical in both adults and children; however, while imaging findings guide management in adults, hemodynamic stability is the primary determinant in pediatric patients. After initial diagnosis, the primary role of imaging in pediatric patients is to determine the level and duration of care. We present a comprehensive literature review regarding the mechanism of injury, imaging, management, and complications of traumatic splenic injury in pediatric patients. Multiple patients are presented with an emphasis on the American Association for the Surgery of Trauma organ injury grading system. Clinical practice guidelines from the American Pediatric Surgical Association are discussed and compared with our experience at a large community hospital, with recommendations for future practice guidelines.     

Traumatic pelvic fractures in children and adolescents

Although traumatic pelvic fractures in children are relatively rare, these injuries are identified in about 5% of children admitted to level 1 trauma centers after blunt trauma.1, 2, 3, 4 Such injuries differ from adult pelvic fractures in important ways and require distinct strategies for management. While the associated mortality rate for children with pelvic fractures is much lower than that for adults, the patient may require urgent surgical intervention for associated life-threatening injuries such as head trauma and abdominal injury. Unstable pelvic ring fractures should be acutely managed using an initial approach similar to that used in adult orthopedic traumatology. Although very few pediatric pelvic fractures will ultimately need surgical treatment, patients with these injuries must be followed over time to confirm proper healing, ensure normal pelvic growth, and address any potential complications. The trauma team suspecting a pelvic fracture in a child must understand the implication of such a finding, identify fracture patterns that increase suspicion of associated injuries, and involve pediatric or adult orthopedic specialists as appropriate during the management of the patient.
