A Comprehensive Experimental Study on Head Trauma in a 3-Year-Old Child Due to Unmanned Aerial Vehicle Collisions

Purpose This research aimed to evaluate the biomechanical impact on a 3-year-old child's head during collisions with unmanned aerial vehicles (UAVs), focusing on the effects of UAV mass, impact velocity, and impact direction, using the Head Injury Criterion (HIC) for assessment. Methods Experiments simulated impacts with UAVs of varying masses (249g, 500g, 900g) and velocities (19.0, 24.0, 29.0 m/s) from different directions. HIC values were measured for each scenario and analyzed in relation to the Abbreviated Injury Scale to determine potential injury severity. Results The findings showed that both the UAV's mass and impact velocity have a significant influence on the HIC value, with higher figures indicating a greater risk of serious injury. For the UAVs weighing 249 g and 500 g, frontal impacts resulted in the highest HIC values; however, for the UAV weighing 900 g, the highest HIC value occurred for the back hit. Moreover, injury risk was found to escalate non-linearly with increased velocity, especially for heavier UAVs. Conclusions The study emphasizes the critical influence of UAV mass and impact velocity on the severity of head injuries in children. Increased mass and velocity correlated with higher HIC values, indicating a greater likelihood of severe injury. Frontal impacts were particularly hazardous for lighter UAVs, while rear impacts were more dangerous for heavier UAVs. These findings support the need for stringent regulations on UAV operational parameters, focusing on speed and mass limitations, to mitigate the risk of severe head injuries in children.

Shaken Baby Syndrome (SBS) or Pediatric Abusive Head Trauma from Shaking: Guidelines for Interventions During the Perinatal Period from the French National College Of Midwives.

Shaken baby syndrome is the most severe head injury in children. Shaking is an extremely violent gesture, often repeated. The children affected are generally less than a year old, in 2/3 of cases, less than 6 months old. More than 10% of them die, and more than three-quarters of the survivors have long-term effects. Prevention is therefore essential. When a parent (or any person) is strongly upset by an infant's uncalmable crying, the best thing for them to do is to lay the child down in a supine position in his or her bed, leave the room, and then ask for help.

Prediction of Poor Prognosis After Severe Head Injury in Children Using Logistic Regression

Head trauma is one of the main causes of death in childhood and often leaves severe disability with serious neurological damage. Appropriate treatment must be provided immediately to improve outcomes. This study was performed to identify factors associated with a poor prognosis at an early stage of severe head injury in children. The subjects were registered in the Japan Neurotrauma Data Bank. They were 119 children (mean age, 8 years; male, 67.2%) with severe head injury registered during a period of 4 years (from July 1, 2004 to June 30, 2006 and from July 1, 2009 to June 30, 2011). Univariate and multivariate analyses were performed to examine relationships among factors and outcome 6 months after discharge. Logistic regression analysis was performed to develop models for poor prognosis and death. Outcome was evaluated based on the Glasgow Outcome Scale: 73 children (61.3%) had good recovery, 11 (9.2%) had moderate disability, 8 (6.7%) had severe disability, 4 (3.3%) were in a vegetative state, and 23 (19.3%) had died. Four factors were identified as predictors of a poor prognosis: serum glucose level greater than or equal to 200 mg/dL, Glasgow Coma Scale score on admission less than or equal to 5, presence of mydriasis, and presence of traumatic subarachnoid hemorrhage. Three factors were identified as predictors of death: serum glucose level greater than or equal to 200 mg/dL, Glasgow Coma Scale score on admission less than or equal to 5, and presence of mydriasis. Using these predictors, subsequent exacerbation may be predicted just after arrival at the hospital and appropriate treatment can be provided immediately.

Severe Pediatric Head Injury During the Iraq and Afghanistan Conflicts.

Much has been written about injuries sustained by US and coalition soldiers during the Global War on Terrorism campaigns. However, injuries to civilians, including children, have been less well documented. To describe the epidemiologic features and outcomes associated with isolated severe head injury in children during Operations Enduring Freedom and Iraqi Freedom (OEF and OIF). A retrospective review of children (<18 years old) in the Joint Theater Trauma Registry with isolated head injury (defined as an Abbreviated Injury Score Severity Code >3) and treated at a US combat support hospital in Iraq or Afghanistan (2004-2012). The primary outcome was in-hospital mortality. We identified 647 children with severe isolated head injuries: 337 from OEF, 268 from OIF, and 42 nontheater specific. Most were boys (76%; median age = 8 years). Penetrating injuries were most common (60.6%). Overall, 330 (51%) children underwent a craniotomy/craniectomy; 156 (24.1%) succumbed to their injuries. Admission Glasgow Coma Score was predictive of survival among the entire cohort and each of the individual conflicts. Male sex also significantly increased the odds of survival for the entire group and OEF, but not for OIF. Closed-head injury improved the predictive ability of our model but did not reach statistical significance as an independent factor. This is the largest study of combat-related isolated head injuries in children. Admission Glasgow Coma Score and male sex were found to be predictive of survival. Assets to comprehensively care for the pediatric patient should be established early in future conflicts.

Severe Head Injury in Children: The Benefits of Liberal Imaging Outweigh the Risks of Ionizing Radiation from Computed Tomography

Role of hyperbaric oxygen therapy in severe head injury in children

Aim:A brain injury results in a temporary or permanent impairment of cognitive, emotional, and/or physical function. Predicting the outcome of pediatric brain injury is difficult. Prognostic instruments are not precise enough to reliably predict individual patient's mortality and long-term functional status. The purpose of this article is to provide a guide to the strengths and limitations of the use of hyperbaric oxygen therapy (HBOT) in treating pediatric patients with severe brain injury.Materials and Methods:We studied total 56 patients of head injury. Out of them 28 received HBOT. Only cases with severe head injury [Glasgow Coma Scale (GCS) < 8] with no other associated injury were included in the study group. After an initial period of resuscitation and conservative management (10–12 days), all were subjected to three sessions of HBOT at 1-week interval. This study group was compared with a control group of similar severity of head injury (GCS < 8).Results:The study and control groups were compared in terms of duration of hospitalization, GCS, disability reduction,and social behavior. Patients who received HBOT were significantly better than the control group on all the parameters with decreased hospital stay, better GCS, and drastic reduction in disability.Conclusion:In children with traumatic brain injury, the addition of HBOT significantly improved outcome and quality of life and reduced the risk of complications.

Severe head injury in children: intensive care unit activity and mortality in England and Wales

Objective: To explore the relationship between volume of paediatric intensive care unit (PICU) head injury (HI) admissions, specialist paediatric neurosurgical PICU practice, and mortality in England and Wales.Methods: Analysis of HI cases (age <16 years) from the Paediatric Intensive Care Audit Network national cohort of sequential PICU admissions in 27 units in England and Wales, in the 5 years 2004–2008. Risk-adjusted mortality using the Paediatric Index of Mortality (PIM) model was compared between PICUs aggregated into quartile groups, first to fourth based on descending number of HI admissions/year: highest volume, medium–higher volume, medium–lower volume, and lowest volume. The effect of category of PICU interventions – observation only, mechanical ventilation (MV) only, and intracranial pressure (ICP) monitoring – on outcome was also examined. Observations were reported in relation to specialist paediatric neurosurgical PICU practice.Results: There were 2575 admissions following acute HI (4.4% of non-cardiac surgery PICU admissions in England and Wales). PICU mortality was 9.3%. Units in the fourth-quartile (lowest volume) group did not have significant specialist paediatric neurosurgical activity on the PICU; the other groups did. Overall, there was no effect of HI admissions by individual PICU on risk-adjusted mortality. However, there were significant effects for both intensive care intervention category (p<0.001) and HI admissions by grouping (p<0.005). Funnel plots and control charts using the PIM model showed a hierarchy in increasing performance from lowest volume (group IV), to medium–higher volume (group II), to highest volume (group I), to medium–lower volume (group III) sectors of the health care system.Conclusions: The health care system in England and Wales for critically ill HI children requiring PICU admission performs as expected in relation to the PIM model. However, the lowest-volume sector, comprising 14 PICUs with little or no paediatric neurosurgical activity on the unit, exhibits worse than expected outcome, particularly in those undergoing ICP monitoring. The best outcomes are seen in units in the mid-volume sector. These data do not support the hypothesis that there is a simple relationship between PICU volume and performance.

Intracranial pressure and cerebral perfusion pressure as risk factors in children with traumatic brain injuries

The authors evaluated the initial intracranial pressure (ICP) and cerebral perfusion pressure (CPP) as prognostic factors in severe head injury in children and tried to determine the optimal CPP range. The authors performed a 9-year retrospective review of all patients with severe traumatic brain injuries (TBIs) who required invasive ICP monitoring and were admitted to the pediatric intensive care unit at their institution between January 1995 and December 2003. These patients had Glasgow Coma Scale scores lower than 8 and/or required ICP monitoring due to worsening neurological status or neuroimaging results suggestive of cerebral hypertension. Clinical summaries and imaging studies were reviewed. Data for 156 pediatric patients who ranged in age from 1 to 18 years were obtained. Half of these patients presented with normal initial ICPs (< 20 mm Hg), and a good outcome was achieved in 80% of these children. An unfavorable outcome was observed in more than 60% of patients with an initial CPP lower than 40 mm Hg. The proportion of patients with an unfavorable outcome decreased to 10% with initial CPPs higher than 60 mm Hg, but patients with initial CPPs higher than 70 mm Hg did not improve. Initial ICP and CPP measurements were useful as prognostic factors in pediatric patients with severe TBIs: patients with initial CPPs between 40 and 70 mm Hg were found to have a better neurological prognosis than those with CPPs either higher or lower than that range.

Factors Associated With Incidence of "Inappropriate" Ambulance Transport in Rural Areas in Cases of Moderate to Severe Head Injury in Children

Ambulance transport of pediatric trauma patients to designated trauma centers in cases of moderate and severe injury is not always performed, which has been shown to result in poor treatment outcomes. Determination of factors involved in inappropriate patient transport, especially in rural areas, remains an important avenue of research. To identify factors involved in ambulance transport of pediatric patients sustaining moderate-to-severe head injury to nondesignated trauma centers in rural North Dakota. Emergency medical service ambulance records for North Dakota from 1995 to 2000 were used. One hundred fifty-six cases of pediatric head injuries with Glasgow Coma Scale scores < or =12 and transported by rural ambulance squads were selected. A logistic regression analysis was conducted to identify a set of significant predictors of cases of inappropriate deliveries to acute care facilities with no trauma-center designation of any level (II-V). Greater distance (mean = 19.96 miles) to the nearest trauma center and shorter distance traveled by the ambulance squad to the receiving facility (mean = 19.07 miles) corresponded to higher probabilities of mistriage, especially when a child was Native American (16 times more likely) and the transportation was conducted in the winter (9 times more likely). Timely delivery of pediatric trauma patients to designated trauma centers is encumbered in the winter, particularly in Native American communities, because of the greater traveling distances, which could be counteracted by better mobilization of available resources aimed at administration of optimal trauma care.

Hyperosmolar Therapy in the Treatment of Severe Head Injury in Children

Traumatic brain injury is the result of a primary, acute injury and is complicated by the development of secondary injury due to hypotension and hypoxia. Cerebral edema due to brain injury compromises the delivery of essential nutrients and alters normal intracranial pressure. The Monroe-Kellie Doctrine defines the principles of intracranial pressure homeostasis. Treatment for intracranial hypertension is aimed at reducing the volume of 1 of the 3 intracranial compartments, brain tissue, blood, and cerebrospinal fluid. Hyperosmolar therapy is one treatment intervention in the care of patients with severe head injury resulting in cerebral edema and intracranial hypertension. The effect of hyperosmolar solutions on brain tissue was first studied nearly 90 years ago. Since that time, mannitol has become the most widely used hyperosmolar solution to treat elevated intracranial pressure. Increasingly, hypertonic saline solutions are being used as an adjunct to mannitol in basic science research and clinical studies. Hyperosmolar solutions are effective in reducing elevated intracranial pressure through 2 distinct mechanisms: plasma expansion with a resultant decrease in blood hematocrit, reduced blood viscosity, and decreased cerebral blood volume; and the creation of an osmotic gradient that draws cerebral edema fluid from brain tissue into the circulation. The pediatric section of the Society of Critical Care Medicine and the World Federation of Pediatric Intensive and Critical Care Societies adapted previously published guidelines for the treatment of adult brain injury into guidelines for the treatment of children with traumatic brain injury. These guidelines offer recommendations for the management of children with severe head injury, including the use of mannitol and hypertonic saline to treat intracranial hypertension. Acute and critical care pediatric advanced practice nurses caring for children with severe head injury should be familiar with management guidelines and the use of hyperosmolar solutions. The purpose of this article is to assist the advanced practice nurse in understanding the role of hyperosmolar therapy in the treatment of pediatric traumatic brain injury and review current guidelines for the use of mannitol and hypertonic saline.

Rehabilitation in severe head injury in children: outcome and provision of care

Functional outcome and provision of care to 82 children (males: females 2.7: 1; age range 0 to 16 years) with severe head injury were investigated. The children were admitted to the intensive care units of the Regional Neuroscience Units of the Greater Manchester and Lancashire districts of the North West Region of the UK between 1994 and 1996. A questionnaire was devised based on 12 areas of recovery and data were collected at discharge and 6 weeks, 6 months and 12 months from discharge. Data were collected during home visits and at joint assessment at 12 months with the district consultant community paediatrician (CCP). Early involvement of the CCP enhanced the provision of needs at discharge and 6 weeks after discharge, as did a period of stay in district‐level care before discharge home. CCPs received formal notification of the injured child in only 32% of cases by discharge, and 54% of cases by 6 months. Sixty‐five per cent of children required early educational support but structured help reached only 55% of these children by the end of the study. Integrated planning between health and education was achieved in about half of the study population. Good physical recovery was achieved by the majority of children but parents said they did not feel prepared for the degree of help which their child still required 12 months after discharge. Children who required anticonvulsants at 12 months’follow‐up scored significantly lower on cognitive potential. Psychosocial family functioning deteriorated in a substantial number of families according to parental perception. Prevalence of this perception did not diminish over the study period. Aspects of caregivers’understanding and the child's language deficits, self‐care skills, fine and gross motor performance, as well as family, social, and financial consequences were assessed. A dedicated and integrated approach to assessment and provision of care across the domains of hospital, education, and community is discussed.

Unilateral decompressive craniectomy for children with severe brain injury. Report of seven cases and review of the relevant literature.

Severe head injuries in children (under 15 years of age) have many features that differentiate them from head injuries in adults. In such cases, non-surgical treatment cannot always prevent fatal herniation. We report on seven cases of children with severe head injury, presenting with decorticate posturing and treated by unilateral decompressive craniectomy. The aim of the unilateral decompressive craniectomy was to decompress the midbrain and the brainstem. Post-operatively, all patients showed good recovery within 5 weeks (Glasgow Coma Scale score 15). The alternative treatment modalities are discussed critically in an attempt to determine the value of the unilateral decompressive craniectomy procedure and to define the clinical parameters that might identify those children most likely to benefit from this technique. the unilateral decompressive craniectomy has an advantage over non-surgical treatment of children with severe brain injury and should be considered in their management.

Prehospital endotracheal intubation for severe head injury in children: a reappraisal.

Controversy exists regarding the efficacy of prehospital assisted ventilation by endotracheal intubation (ETI) versus bag-valve-mask (BVM) in serious pediatric head injury. The National Pediatric Trauma Registry (NPTR-3) data set was analyzed to examine this question. NPTR-3 (n = 31,464) was queried regarding the demographics, injury mechanism, injury severity, prehospital interventions, transport mode, mortality rate, injury complications, procedure and equipment failure or complications, and functional outcome of seriously head-injured patients (n = 578) with comparable injury mechanisms and injury severity who received endotracheal intubation (ETI) (n = 479; 83%) versus those who received BVM (n = 99; 17%). Mortality rate was virtually identical between the 2 groups (ETI = 48%, BVM = 48%), although children receiving ETI were significantly older (P < .01), more often transported by helicopter (P < .01), and more often received intravenous fluid in the field (P < .05). However, injury complications affecting nearly every body system or organ (except kidney, gut, and skin) occurred less often in children receiving ETI (ETI = 58%, BVM = 71%, P < .05). Procedure and equipment failure or complications, and functional outcome, were similar between the 2 groups. Prehospital endotracheal intubation appears to offer no demonstrable survival or functional advantage when compared with prehospital bag-valve-mask for prehospital assisted ventilation in serious pediatric head injury. Injury complications appear to occur somewhat less often among patients intubated in the field.

Statistical method for the estimation of cerebral blood flow using the Kety–Schmidt technique

The Kety-Schmidt technique for the measurement of cerebral blood flow (CBF) has been in use for many years, but efficient statistical methods for producing estimates of CBF have received little attention. This paper proposes simple statistical models for this problem and explores their properties using data from a recent study of severe head injury in children. The method, which can readily be implemented on a personal computer, allows the uncertainty in the estimate of CBF to be quantified.

Severe head injury in children: impact of risk factors on outcome.

Outcome after severe head injury has been shown in some studies to be more favorable in children than in adults. Mortality rates reported range between 20% and 40% for children. Only contradicting data are available regarding the impact of trauma modalities on long-term outcome, or the relative influence of head fractures, intracranial hemorrhages, and brain edema on survival or neurologic sequelae in children. A retrospective study in a tertiary care facility of long-term outcome of children after severe head injury, and analysis of risk factors for poor outcome. All children up to 16 years of age with severe head injury (Glasgow Coma Scale [GCS] score < or = 8), which have been treated in the pediatric intensive care unit from 1977 until 1994 in a single institution. A total of 150 children with severe head injury (GCS score < or = 8) were treated, 92 of them (61.3%) had traffic-related injuries. The median age was 6.6 years (SD +/- 3.6). There were 96 boys (64%) and 54 girls (36%). Sixty-five children (43.3%) had skull fractures, 87 patients (58.0%) developed an intracranial hemorrhage, and 79 patients (52.7%) developed a diffuse brain swelling/edema visible in computed tomographic scans within 72 hours after trauma. Of 150 children treated, 33 died (22%). In most cases, death was related to the development of secondary brain edema. Fifty-nine children (39.3%) had severe neurologic impairments at the time of discharge. The most significant risk factors for adverse outcome, shown by multivariate analysis, were primary areflexia and secondary brain edema. The risk for development of brain edema and poor prognosis was well predicted by the GCS score. The overall death rate in this study of children with severe head injury was low (22%) compared with other studies. However, the incidence of severe neurologic impairment at discharge remained high. The major risks for death or neurologic impairment were primary areflexia and the development of secondary brain swelling/edema, indicated by a low GCS score.

Reduced body cell mass following severe head injury in children: implications for rehabilitation.

Increased proteolysis, muscle catabolism and altered body composition have been well documented after severe head injury, but the extent of these effects in children, and whether they extend into rehabilitation, have not been studied. This study determined nutritional status and body composition, with particular reference to the body cell mass (BCM), of head injured children at entry into a rehabilitation programme, and compared body composition analysis with anthropometric nutritional assessment. Nineteen head injured children (nine males, 10 females, mean age 9.1 +/- 4.3 years range 1.2-15.1 years) were measured for height, weight and total body potassium (TBK, a measure of body cell mass) on referral to rehabilitation after the acute phase (mean 38.1 days post-injury). Data was compared with expected normative data derived from healthy age and gender matched children. Nutritional status was determined by two separate criteria based on either anthropometric or body composition methods. The mean percentage of expected TBK for height was 84.4 +/- 15%, significantly below the clinically acceptable level for body cell mass (90% of expected). Using the anthropometric definition, only 1/19 was undernourished, whereas 12/19 had poor nutritional status using body composition (chi 2 = 7.58, p = 0.006). The data revealed a significant depletion in the metabolically active BCM in the presence of normal anthropometry, suggestive of significant muscle wasting. These findings have important pathophysiological and clinical implications in the rehabilitation of children following major head trauma.
