Caregiver reported long-term outcomes in children with major trauma and traumatic brain injuries: A single-centre retrospective study.

We aim to investigate the functional outcomes and long-term health-related quality of life (HRQOL) in children with major trauma associated with traumatic brain injury (TBI). We performed a retrospective review of records among patients >2 and ≤16 years old in a tertiary paediatric hospital between January 2014 and October 2019 with major trauma (Injury Severity Score of ≥16) and TBI of all severities. We recorded each child's Glasgow Outcome Scale-Extended Pediatric Version (GOS-E Peds) at 12 months post-injury and Pediatric Quality of Life Inventory (PedsQL) scores at 6 and 12 months post-injury based on the parent proxy-report scales. We included 53 patients with a median age of 9.0 years old (interquartile range 2.3-15.5). Most injuries were due to falls (30, 56.6%) or road traffic collisions (15, 28.3%); 41 patients (77.3%) required intensive care while 30 patients (56.6%) underwent neurosurgical intervention. Most patients (43, 81.1%) had GOS-E Peds scores of ≤2 at 12 months post-injury. We reported a significant mean difference between the 6- and 12-month parent-reported scores for physical functioning (6.6, 95% confidence interval [CI] 0.3-12.8, P=0.041), psychosocial functioning (4.1, 95% CI 1.0-7.2, P=0.012) and overall scores (5.0, 95% CI 1.4-8.7, P=0.008). Compared with the validated PedsQL scores, our mean scores were higher across all domains at 12 months. With current standard of care, parents of children with major trauma and TBI reported gains in quality of life, physical, psychosocial and overall function between 6 and 12 months post-injury.

35 Preliminary reliability of the Coma Recovery Scale, Revised (CRS-R) in children with a history of disorders of consciousness after acquired brain injury

Objective:The Coma Recovery Scale-Revised (CRS-R) is the gold standard assessment of adults with disorders of consciousness (DoC); however few studies have examined the psychometric properties of the CRS-R in pediatric populations. This study aimed to demonstrate preliminary intra-rater and inter-rater reliability of the CRS-R in children with acquired brain injury (ABI).Participants and Methods:Participants included 3 individuals (ages 10, 15, and 17 years) previously admitted to an inpatient pediatric neurorehabilitation unit with DoC after ABI who were followed in an outpatient brain injury clinic due to ongoing severe disability. ABI etiology included traumatic brain injury (TBI; n=2) and encephalitis (n=1). Study participation took place on average 4.6 years after injury (range 2-9). The Glasgow Outcome Scale-Extended, Pediatric Version (GOS-E Peds), a measure of outcome after pediatric brain injury, was administered as part of screening. Two participants were placed in the GOS-E Peds “lower severe disability” category (i.e., score of 6) and one was placed in the “upper severe disability” category (i.e., score of 5). The CRS-R includes 6 subscales measuring responsivity including Auditory (range 0-4), Visual (range 05), Motor (range 0-6), Oromotor/Verbal (range 03), Communication (range 0-2), and Arousal (range 0-3) with higher scores indicating higherlevel function. Subscales are totaled for a CRS-R Total score. Behaviors shown during the CRS-R are used to determine state of DoC [Vegetative State (VS), Minimally Conscious State (MCS) or emergence from a minimally conscious state (eMCS)] based on 2002 Aspen Guidelines. Participants were administered the CRS-R three consecutive times on the same day. Administrations were completed by two raters in this order: Rater 1 (1A), Rater 1 (1B) and Rater 2. Intra-rater reliability was deemed by percent agreement across the 6 subscales between Rater 1A and 1B. Inter-rater reliability was deemed by percent agreement across the 6 subscales between 1A and 2.Results:Mean CRS-R Total score for Rater 1A was 22 (SD=1.73, range 20-23), Rater 1B was 22 (SD=1.73, range 20-23), and Rater 2 was 21.33 (SD=2.08, range 19-23). Intra-rater reliability was 100% and inter-rater reliability was 94% across all subscales. All participants were deemed eMCS at all 3 ratings.Conclusions:Data from this very small sample of children suggests that the CRS-R demonstrates both intra-rater and inter-rater reliability in patients with a history of DoC after ABI. Given that all children were at the high end of the scale (eMCS), further research is needed with a larger sample of children with a range of states of DoC.

A multicenter observational study on outcomes of moderate and severe pediatric traumatic brain injuries-time to reappraise thresholds for treatment.

Children with moderate traumatic brain injury (modTBI) (Glasgow Coma Scale (GCS) 9-13) may benefit from better stratification. We aimed to compare neurocritical care utilization and functional outcomes between children with high GCS modTBI (hmodTBI, GCS 11-13), low GCS modTBI (lmodTBI, GCS 9-10), and severe TBI (sTBI, GCS ≤ 8). We hypothesized that patients with lmodTBI have higher neurocritical care needs and worse outcomes than patients with hmodTBI and are similar to patients with sTBI. Prospective observational study from June 2018 to October 2022 in 28 pediatric intensive care units (PICU) in Asia, South America, and Europe. We included children (age < 18years) with modTBI and sTBI admitted to PICU and measured functional outcomes at 3months using the Glasgow Outcome Scale-Extended Pediatric Revision (GOS-E Peds, scale 1-8, 1 = upper good recovery, 8 = death). We analyzed 409 patients: 98 (24%) and 311 (76%) with modTBI and sTBI, respectively. Patients with lmodTBI (vs. hmodTBI) were more likely to have invasive ICP monitoring (32.3% vs. 4.5%, p < 0.001), longer PICU stay (days, median [IQR]; 5.00 [4.00, 9.75] vs 4.00 [2.00, 5.00], p = 0.007), and longer hospital stay (days, median [IQR]: 13.00 [8.00, 17.00] vs. 8.00 [5.00, 12, 25], p = 0.015). Median GOS-E Peds scores were significantly different (hmodTBI (1.00 [1.00, 3.00]), lmodTBI (3.00 [IQR 2.00, 5.75]), and sTBI (5.00 [IQR 1.00, 6.00]) (p < 0.001)). After adjusting for age, sex, presence of polytrauma and cerebral edema, lmodTBI, and sTBI remained significantly associated with higher GOS-E scores (adjusted coefficient (standard error): 1.24 (0.52), p = 0.018, and 1.27 (0.33), p < 0.001, respectively) compared with hmodTBI. Children with lmodTBI have higher rates of neurocritical care utilization and worse functional outcomes than those with hmodTBI but better than those with sTBI. Children with lmodTBI may benefit from guideline-based management similar to what is implemented in children with sTBI. This work was performed in hospitals within the PACCMAN and LARed networks.

Abusive head trauma in infants: An observational single centre study comparing developmental and functional outcome between 18 months and 5 years

BackgroundAbusive head trauma (AHT) is a major cause of traumatic brain injury in infancy. This exploratory study compared standardized developmental assessment versus functional outcome assessment between 18 months and 5 years of age following AHT in infancy. MethodsObservational cross-sectional study after surviving AHT in infancy. Seventeen children between 18 months and 5 years of age underwent clinical examination, developmental assessment using the Schedule of Growing Skills II (SGS II) and functional assessment using the Glasgow Outcome Scale-Extended Pediatric Revision (GOS-E Peds). Additional clinical information was extracted from medical records. ResultsAge at assessment ranged from 19 to 53 months (median 26 months). Most (n = 14) were delayed in at least 1 domain, even without neurological or visual impairment or visible cortical injury on neuroimaging, including 8 children with favourable GOS-E Peds scores. The most affected domain was hearing and language. Delay in the manipulative domain (n = 6) was associated with visual and/or neurological impairment and greater severity of delay across multiple domains. Eleven (64.7 %) had GOS-E Peds scores indicating good recovery, with positive correlation between GOS-Peds scores and number of domains delayed (r = 0.805, p < 0.05). ConclusionThe SGS-II detects behavioural and cognitive deficits not picked up by the GOS-E Peds. Combining both tools for assessment of AHT survivors under 5 years of age provides a comprehensive profile which addresses multiple domains of development and function, facilitating targeted intervention. Detection of developmental problems in the majority of survivors makes AHT prevention a public health priority.

Long-Term Outcomes of Pediatric Traumatic Brain Injury Following Inpatient Rehabilitation.

Assess residual disability in youth with traumatic brain injury (TBI) treated in a pediatric inpatient rehabilitation unit and examine associations of disability with inpatient status and measures of concurrent functioning. Large, urban, quaternary care children's hospital in the Midwestern United States. Forty-five youth aged 6 to 18 years treated in an inpatient rehabilitation unit for mild-complicated to severe TBI at a minimum of 12 months postdischarge (mean = 3.5 years). Retrospective chart review of clinical data collected from standard clinical care at admission and discharge combined with follow-up data examining current functioning at the time of study enrollment. Glasgow Outcome Scale-Extended, Pediatric Revision (GOS-E Peds), Neurology Quality of Life Measurement System Short Form (NeuroQOL) Social Interaction with Peers and Cognitive Short Forms, Patient Reported Outcomes Measurement Information System (PROMIS) Global Health Scale, Strengths and Difficulties Questionnaire, and the Behavior Rating Inventory of Executive Function, 2nd Edition (BRIEF-2). Based on parent report at follow-up, 62% of the children had residual TBI-related disabilities on the GOS-E Peds, while 38% reported "good recovery." Children with residual disability also reported more long-term problems in overall health, social relationships, emotional regulation, behaviors, and executive functioning than those with no residual disability. Measures of functional independence and cognitive recovery at discharge were associated with these impairments. More than half of the children with TBI in this study had residual disability more than 1 year after inpatient rehabilitation. Findings highlight the associations between measures of functional independence and cognitive recovery during inpatient rehabilitation with later outcomes and underscore the need for continued services to support the needs of children with TBI following their inpatient rehabilitation stay.

Optic nerve sheath diameter and pulsatility index for the diagnosis and follow-up in pediatric traumatic brain injury: a prospective observational cohort study.

Invasive neuromonitoring could be difficult in children with traumatic brain injury (TBI). This study aimed to determine whether noninvasive intracranial pressure (nICP), calculated via pulsatility index (PI) and optic nerve sheath diameter (ONSD) had correlated with each other and patient outcome. All moderate-severe TBI patients were eligible. Patients with a diagnosis of intoxication that did not affect the mental status or cardiovascular system were enrolled as controls. The PI measurements were routinely performed bilaterally on the middle cerebral artery. A software (QLAB's Q-Apps) was used to calculate PI, which further placed the ICP equation of Bellner et al. Linear probe with a 10MHz frequency transducer to measure ONSD, which further placed the ICP equation of Robba et al. All measurements were performed by a point-of-care ultrasound certified pediatric intensivist under the supervision of a neurocritical care specialist, before and 30min after a hypertonic saline (HTS) infusion for every 6h when the patient's mean arterial pressure, heart rate, body temperature, hemoglobin, and blood CO2 levels were within normal ranges. The secondary outcome was the effect of hypertonic saline (HTS) on nICP. Delta-sodium values of each HTS infusion were calculated as a difference between pre- and post-measurements. Twenty-five TBI patients (200 measurements) and 19 controls (57 measurements) were included. Median nICP-PI and nICP-ONSD on admission were significantly higher in the TBI group (11.03 (9.98-12.63), p = 0.004, and 13.14 (12.27-14.64), p < 0.001, respectively). Median nICP-ONSD of severe TBI patients were higher than moderate TBI patients (13.58 (13.14-15.71) and 12.30 (9.83-13.14), respectively, p = 0.013). The median nICP-PI was the same across the type of injury (falls and motor vehicle accidents), while the median nICP-ONSD of the motor vehicle accident group was higher than falls. The first nICP-PI and nICP-ONSD measurements in PICU and admission pGCS were negatively correlated (r = - 0.562, p = 0.003 and r = - 0.582, p = 0.002, respectively). The mean nICP-ONSD during the study period and admission pGCS and GOS-E peds score significantly correlated. However, the Bland-Altman plots showed significant bias between the two methods of ICP except after 5th dose of HTS. All nICP values significantly decreased in time, and it was most obvious after the 5th dose of HTS. No significant correlations were found between delta sodium levels and nICP. Noninvasive estimation of ICP is helpful for the management of pediatric severe TBI patients. nICP driven by ONSD is more consistent with clinical findings of increased ICP but not useful as a follow-up tool in acute management because of slow circulation of CSF around the optic sheath. The correlation between admission GCS scores and GOS-E peds score favors ONSD as a good candidate for determining disease severity and predicting long-term outcomes.

Heart Rate Variability in Children with Moderate and Severe Traumatic Brain Injury: A Prospective Observational Study

AbstractThe aim of this study was to assess the feasibility of continuous monitoring of heart rate variability (HRV) in children with traumatic brain injury (TBI) hospitalized in a pediatric intensive care unit (PICU) and collect preliminary data on the association between HRV, neurological outcome, and complications. This is a prospective observational cohort study in a tertiary academic PICU. Children admitted to the PICU ≤24 hours after moderate or severe TBI were included in the study. Children suspected of being brain dead at PICU entry or with a pacemaker were excluded. Children underwent continuous monitoring of electrocardiographic (ECG) waveforms over 7 days post-TBI. HRV analysis was performed retrospectively, using a standardized, validated HRV analysis software (CIMVA). The occurrence of medical complications (“event”: intracranial hypertension, cerebral hypoperfusion, seizure, and cardiac arrest) was prospectively documented. Outcome of children 6 months post-TBI was assessed using the Glasgow Outcome Scale – Extended Pediatric (GOS-E Peds). Fifteen patients were included over a 20-month period. Thirteen patients had ECG recordings available and 4 had &gt;20% of missing ECG data. When ECG was available, HRV calculation was feasible (average 88%; range 70–97%). Significant decrease in overall HRV coefficient of variation and Poincaré SD2 (p &lt; 0.05) at 6 hours post–PICU admission was associated with an unfavorable outcome (defined as GOS-E Peds ≥ 3, or a deterioration of ≥2 points over baseline score). Several HRV metrics exhibited significant and nonsignificant variation in HRV during event. This study demonstrates that it is feasible to monitor HRV in the PICU provided ECG data are available; however, missing ECG data are not uncommon. These preliminary data suggest that altered HRV is associated with unfavorable neurological outcome and in-hospital medical complications. Larger prospective studies are needed to confirm these findings and to explore if HRV offers reliable and clinically useful prediction data that may help clinical decision making.

Outcome Measurement in Children With a History of Disorders of Consciousness After Severe Brain Injury: Telephone Administration of the Vineland Adaptive Behavior Scales, Third Edition, and Glasgow Outcome Scale-Extended Pediatric Revision.

Examine initial feasibility and utility of a battery of measures administered via telephone interview with a caregiver for describing long-term outcomes in individuals with a history of disorders of consciousness (DoC) after pediatric acquired brain injury (ABI). Cross-sectional. Caregiver interview administered via telephone. Convenience sample admitted to an inpatient pediatric neurorehabilitation unit with DoC after ABI at least 1 year prior to assessment (n = 41, 5-22 yr old at assessment). None. The Vineland Adaptive Behavior Scales, Third Edition (Vineland-3), and Glasgow Outcome Scale-Extended Pediatric Revision (GOS-E Peds) were examined. Administration time of the Vineland-3 ranged from 13 to 101 minutes (m = 50) and the GOS-E Peds ranged from 2 to 10 minutes (m = 3). Vineland-3 Adaptive Behavior Composite (ABC) ranged from standard scores (SSs) of 20 (exceptionally low) to 100 (average) and GOS-E Peds scores ranged from 3 (i.e., upper moderate disability) to 7 (vegetative state). Lower adaptive functioning on the Vineland-3 ABC was strongly associated with greater disability on the GOS-E Peds (r = -0.805). On the Vineland-3 ABC, 19.5% earned the lowest possible score, whereas 12.2% obtained the lowest possible score for survivors on the GOS-E Peds; only 7.3% earned lowest scores on both measures. The Vineland-3 and GOS-E Peds were feasibly administered by telephone and were complementary in this cohort; the GOS-E provided a quick and easy measure of gross functional outcome, whereas the Vineland-3 took longer to administer but provided a greater level of detail about functioning. When both measures were used together, the range and variability of scores were maximized.

738: CRITICAL CARE UTILIZATION AND OUTCOMES IN PEDIATRIC MODERATE TRAUMATIC BRAIN INJURY

Introduction: Patients with moderate traumatic brain injury (mTBI) have outcomes that range from good functional recovery to death. We compared neurocritical care utilization of patients with high Glasgow Coma Scale (GCS) mTBI (hmTBI, GCS 11-13) and low GCS mTBI (lmTBI, GCS 9-10), and functional outcomes of patients with mTBI and severe TBI (sTBI, GCS < 9) 3-months post injury. We hypothesize that patients with lmTBI have higher neurocritical care needs and worse outcomes than patients with hmTBI and similar to patients with sTBI. Methods: We performed a dual continent prospective observational study from June 2018 – April 2022 among children (age < 16 years) with mTBI and sTBI admitted to 33 pediatric intensive care units in the Pediatric Acute & Critical Care Medicine Asian Network (PACCMAN) and LARed: Red Colaborativa Pediatrica de Latinoamerica. We assessed functional outcomes using the Glasgow Outcome Scale – Extended Pediatric Revision (GOS-E Peds, scale 1-8, 1 = upper good recovery, 8 = death). Results: We analyzed 396 children with mTBI (24%) and sTBI (70%). In-hospital mortality was 0% and 12%, respectively. Compared with mTBI, the sTBI group was more likely to be mechanically ventilated in the first hour of ICU admission (76.9% vs 28.7%, p< 0.001), have a longer duration of mechanical ventilation (5.00, [interquartile range (IQR) 4.00, 8.50] vs 3.00 [IQR 1.5, 6.00] days, p 0.023), and longer duration of ICU stay (8.00 [IQR 4.00, 13.5] vs 4.00 [IQR 2.00, 7.00] days, p< 0.001). Patients with lmTBI (vs. hmTBI) were more likely to have intracranial pressure (30.3% vs. 3.1%) and intra-arterial blood pressure monitoring (51.5% vs. 27.9%) and a longer duration of ICU stay 5.00 [4.00, 9.74] vs 4.00 [2.00, 6.00]) days, (p < 0.05). At 3 months follow-up, GOS-E Peds scores were different in the 3 groups (hmTBI (1.00 [IQR 1.00, 3.00]), lm TBI (3.00 [IQR 2.00, 6.00]) and sTBI (5.00 [IQR 1.00, 6.25]), (p< 0.001). Conclusions: Patients with lmTBI have higher rates of neurocritical care utilization and worse functional outcomes than those with hmTBI but better than those with sTBI. Our findings highlight the importance of routinely considering multimodal neuromonitoring and ICP targeted treatments to improve outcomes in this population.

Prognostic Factors and Outcome of Surgically Treated Supratentorial versus Infratentorial Epidural Hematoma in Pediatrics: A Comparative Study of 350 Patients at a Tertiary Center of a Developing Country

In children, epidural hematomas (EDHs) constitute around 2% to 3% of all head traumas. The aim of this study is to compare the manifestation, prognostic factors, and outcome of surgically treated supratentorial with infratentorial EDHs in pediatric patients. This is a hospital-based single-center, retrospective study of 350 pediatric patients admitted between January 2016 and December 2021. All pediatric patients to 18 years of age with posttraumatic EDHs with or without other intracranial/extracranial injuries who underwent surgical evacuation were included in the study. Posttraumatic EDHs treated conservatively during the hospital stay and any EDH unrelated to head trauma were excluded. Glasgow Outcome Scale (GOS) score was used to assess functional outcomes at discharge. The status of the patients at 3-month follow-up was assessed by using the pediatric version of the Glasgow Outcome Scale-Extended (GOS-E Peds) Score. Out of 350 patients, 310 had supratentorial EDH and 40 had infratentorial EDH. In supratentorial EDH, the volume of hematoma, mass effect, and the time interval between trauma and surgery correlated with functional outcome (GOS) at discharge. Anisocoria, hypotension, and intradural injury were associated with functional as well as behavioral outcomes (GOS-E Peds) in the supratentorial EDH group. The severity of the injury was correlated with the functional and behavioral outcomes in both groups. Infratentorial EDH has better clinical outcomes than supratentorial EDH in surgically treated pediatric patients. The most significant and consistent factor influencing the outcome in both groups was the Glasgow Coma Score on admission.

Long-Term Neurological, Behavioral, Functional, Quality of Life, and School Performance Outcomes in Children With Guillain-Barré Syndrome Admitted to PICU

BackgroundMost children with Guillain-Barré syndrome (GBS) recover but may suffer from long-term sequelae, interfering with development and quality of life. Owing to the lack of published data, we aimed to assess the long-term neurological, behavioral, functional, quality of life, and school performance outcomes them. MethodsDesign: Cross-sectional observational. Setting: Pediatric intensive care unit. Patients: Children, aged one to 12 years, with GBS admitted over five years (July 2012 to June 2017) were enrolled during one year (July 2017 to June 2018). These children were assessed for the following outcomes: neurological (Hughes disability score, Pediatric Cerebral Performance Category [PCPC], Pediatric Overall Performance Category [POPC], and Glasgow Outcome Scale-Extended Pediatric version [GOS-E Peds] scales), behavioral (Childhood Psychopathology Measurement Schedule [CPMS]), functional (Vineland Social Maturity Scale [VSMS]-Indian Adaptation), quality of life (Pediatric Quality of Life [PedsQL]), and school performance (Parent-Directed Questionnaire). ResultsEighty children were enrolled after a median of 3.0 (1.3-4.2) years from discharge. The majority (95%) had favorable neurological recovery (Hughes disability score 0 to 1). Favorable outcome was noted in 95% of children on PCPC, 87.5% on POPC, 60% on GOS-E Peds, 86.2% on CPMS, 92.5% on VSMS, and 98% on PedsQL. The majority (97.5%) of childre were attending schools, and 57.7% had satisfactory school performance. The presence of quadriparesis at admission, mechanical ventilation, tracheostomy requirement, poor ambulatory status at discharge, and longer pediatric intensive care unit and hospital stay predicted unfavorable neurological outcome on different tools. Absence of quadriparesis at admission and no requirement of mechanical ventilation predicted a favorable result on all outcome measures. ConclusionsOn long-term follow-up, most children with severe GBS showed favorable neurological, behavioral, functional, and quality of life outcomes. Severe clinical presentation and prolonged intensive care unit stay predict poor long-term outcome.

Effects of inpatient rehabilitation after acute care on functional and quality-of-life outcomes in children with severe traumatic brain injury

ABSTRACT Objective Few studies have assessed the effectiveness of the rehabilitation process in children surviving severe traumatic brain injury (TBI). We evaluated whether receiving inpatient rehabilitation after acute hospitalization was associated with better functional outcomes compared to receiving only non-inpatient rehabilitation in children with severe TBI and explored an effect modification for Glasgow Coma Scale (GCS) score at hospital discharge. Methods We included 254 children who received rehabilitation following severe TBI from a multinational observational study. The Pediatric Glasgow Outcome Scale – Extended (GOS-E Peds), parent/guardian-reported and child-reported Pediatric Quality of Life Inventory (PedsQL) at 12 months post-injury were assessed and described using summary statistics. Unadjusted and propensity score-weighted linear/ordinal logistic regression modeling were also performed. Results 180 children received inpatient rehabilitation and 74 children received only non-inpatient rehabilitation after acute hospitalization. Among children with a GCS<13 at discharge, those receiving inpatient rehabilitation had a more favorable GOS-E Peds score (OR = 0.12, p = 0.045). However, no such association was observed in children with a higher GCS. We found no differences in PedsQL scores between rehabilitation groups. Conclusions Future studies are warranted to confirm the benefits of inpatient rehabilitation for children with more severely impaired consciousness when medically stable.

Abusive head injury in the very young: outcomes from a Singapore children's hospital.

Abusive head trauma (AHT) is a serious problem in children. The aims of this study are to identify risk factors that correlate with outcomes for those requiring neurosurgical intervention for very young children with AHT, assessment of variables associated with outcomes, and corroboration of our results with literature. This is an ethics-approved, retrospective study. Inclusion criteria consisted of patients aged 2years old or less with a diagnosis of AHT managed by the Neurosurgical Service, KK Women's and Children's Hospital. Demographical and clinical variables are incorporated in the statistical analyses. Logistic regression was applied to statistically significant variables for the risk prediction model. From 2000 to 2020, 24 patients required surgery for AHT. Timepoint was set at 12months post-diagnosis. Univariate analyses demonstrated that patients with mild TBI were likely to have a favourable GOS-E Peds (p = 0.01), whereas radiological presence of cerebral oedema (p < .001), development of scar epilepsy (p = 0.021), and progression to cerebral palsy (p = 0.001) were associated with unfavourable GOS-E Peds. This is the first study focused on neurosurgical outcomes for very young children with AHT in Singapore. We advocate multidisciplinary efforts to improve outcomes for this devastating condition.

Virtual Reality-Based Sensory Stimulation for Pediatric Disorders of Consciousness: A Pilot Study.

ObjectiveThe purpose of this study was to determine whether virtual reality-based sensory stimulation has the ability to improve the level of consciousness in pediatric disorders of consciousness compared with general rehabilitation.MethodsThirty subjects were divided into a virtual reality (VR) group (n = 15) and a control group (n = 15). Subjects in the VR group received both general rehabilitation and exposure to VR videos; the control group received only general rehabilitation. The Glasgow Coma Scale (GCS), Coma Recovery Scale-Revised (CRS-R), and amplitude-integrated electroencephalogram (EEG) (aEEG) were used to measure the clinical behavioral response and neuroelectrophysiology before and after the treatment. The Glasgow Outcome Scale Extended Pediatric Revised (GOS-E Peds) was used to measure the social and personal functional ability after 3 months.ResultsAfter 2 weeks of treatment, the CRS-R and GCS improved in both groups. However, the VR group had better results than the control group in the CRS-R (p = 0.003) and GCS (p = 0.045). There were no significant differences on aEEG in the two groups after treatment. According to the GOS-E Peds, the improvement of social and personal functional ability had no significant differences in the two groups. Additionally, there were no obvious adverse reactions in the two group during the treatment.ConclusionsThis pilot study indicates potential benefit from the addition of VR to standard rehabilitation in pediatric disorders of consciousness. To further explore the efficacy of VR, a large-sample randomized controlled trial is warranted.

Predicting Outcomes 2 Months and 1 Year After Inpatient Rehabilitation for Youth With TBI Using Duration of Impaired Consciousness and Serial Cognitive Assessment.

To examine predictive utility of the Glasgow Coma Scale (GCS), time to follow commands (TFC), length of posttraumatic amnesia (PTA), duration of impaired consciousness (TFC+PTA), and the Cognitive and Linguistic Scale (CALS) scores in predicting outcomes on the Glasgow Outcome Scale-Extended, Pediatric Revision (GOS-E Peds) for children with traumatic brain injury (TBI) at 2 months and 1 year after discharge from rehabilitation. A large, urban pediatric medical center and inpatient rehabilitation program. Sixty youth with moderate-to-severe TBI (mean age at injury = 13.7 years; range = 5-20). A retrospective chart review. Lowest postresuscitation GCS, TFC, PTA, TFC+PTA, inpatient rehabilitation admission and discharge CALS scores, GOS-E Peds at 2-month and 1-year follow-ups. CALS scores were significantly correlated with the GOS-E Peds at both time points (weak-to-moderate correlation for admission scores and moderate correlation for discharge scores). TFC and TFC+PTA were correlated with GOS-E Peds scores at a 2-month follow-up and TFC remained a predictor at a 1-year follow-up. The GCS and PTA were not correlated with the GOS-E Peds. In the stepwise linear regression model, only the CALS at discharge was a significant predictor of the GOS-E Peds at the 2-month and 1-year follow-ups. In our correlational analysis, better performance on the CALS was associated with less long-term disability, and longer TFC was associated with more long-term disability, as measured by the GOS-E Peds. In this sample, the CALS at discharge was the only retained significant predictor of GOS-E Peds scores at 2-month and 1-year follow-ups, accounting for roughly 25% of the variance in GOS-E scores. As previous research suggests, variables related to rate of recovery may be better predictors of outcome than variables related to severity of injury at a single time point (eg, GCS). Future multisite studies are needed to increase sample size and standardize data collection methods for clinical and research purposes.

Associations between Electroencephalographic Variables, Early Post-Traumatic Seizure Risk, and Outcomes following Pediatric Severe Traumatic Brain Injury

AbstractEarly post-traumatic seizures (PTS) are associated with worse outcomes in children with traumatic brain injury (TBI). Our aim was to identify the association between continuous electroencephalogram (cEEG) characteristics and early PTS risk following pediatric severe TBI. We also evaluated the relationship between cEEG background features and outcomes. A single-center retrospective cohort study was performed on children between 0 and 18 years of age admitted to the pediatric intensive care unit from 2016 to 2019 with severe TBI and cEEG monitoring within 7 days of injury. Raw cEEG tracings were reviewed by an epileptologist in accordance with American Clinical Neurophysiology Society (ACNS) Critical Care EEG terminology. Univariate comparisons were made between children with and without early PTS, as well as between those with and without varying cEEG background features. Eighteen children (31%) of the 59 included had early PTS. Interictal abnormalities, inclusive of sporadic spikes and sharp waves, rhythmic delta activity, or lateralized periodic discharges (LPDs) were more common among children with seizures (100 vs. 22%; p &lt; 0.01). LPDs were also more common in the seizure group (44 vs. 2%; p &lt; 0.01). Background discontinuity was associated with worse Glasgow Outcome Scale—Extended Pediatric Version (GOS-E Peds) scores at discharge and 3-, 6-, and 12-month post-discharge (p &lt; 0.01). Lack of reactivity was also associated with worse GOS-E Peds scores at 3-, 6-, and 12-month post-discharge (p &lt; 0.01). Interictal abnormalities and LPDs were each associated with early PTS following pediatric severe TBI. Larger studies should evaluate if high-risk patients would benefit from prolonged cEEG monitoring and/or more aggressive anti-seizure prophylaxis. Discontinuity and lack of variability were associated with worse outcomes. Future studies should attempt to clarify their role as potential early markers of prognosis.

Role of cerebrospinal fluid tau protein levels as a biomarker of brain injury in pediatric status epilepticus

Background Various biomarkers have been studied for predicting etiology and outcome in status epilepticus (SE); cerebrospinal fluid (CSF) total tau (t-tau) protein levels is foremost among them. Only handful of studies are available regarding role of t-tau in childhood SE. Methodology This prospective study was conducted in a tertiary care center of Northern India in children 6 months −12 years of age. The Cases were patients with convulsive status epilepticus (CSE) whereas Controls were patients without SE and normal CSF. The t-tau levels were done in CSF of both the groups. The outcome was assessed by GOS-E Peds score. Results A total of 50 (62% males) cases and 15 (67% males) controls were enrolled in the study. SE was generalized in 78% cases whereas 14% had refractory SE. Most common etiology of CSE was acute symptomatic (52%), followed by prolonged febrile seizure (24%), remote symptomatic group (14%), unknown etiology (8%) and progressive disorder (2%). Case fatality rate was 10%. Poor outcome was seen in 30% cases. Median (IQR) CSF t-tau levels was significantly lower 2.6 × 103 (0.5–9.4 × 103) pg/ml in cases vs 10.6 × 103 (6.0–14.2 × 103) pg/ml in controls (p = 0.004). There was no significant correlation seen between type, duration, etiology and response to antiepileptic drugs of SE with CSF t-tau levels. Also, no significant correlation of poor sensorium, outcome of SE and critical care needs with CSF t-tau levels was noted. Conclusion CSF t-tau is not a useful diagnostic or prognostic biomarker in pediatric SE.

Implementation of Multimodality Neurologic Monitoring Reporting in Pediatric Traumatic Brain Injury Management

Background/ObjectiveMultimodality neurologic monitoring (MMM) is an emerging technique for management of traumatic brain injury (TBI). An increasing array of MMM-derived biomarkers now exist that are associated with injury severity and functional outcomes after TBI. A standardized MMM reporting process has not been well described, and a paucity of evidence exists relating MMM reporting in TBI management with functional outcomes or adverse events.MethodsProspective implementation of standardized MMM reporting at a single pediatric intensive care unit (PICU) is described that included monitoring of intracranial pressure (ICP), cerebral oxygenation and electroencephalography (EEG). The incidence of clinical decisions made using MMM reporting is described, including timing of neuroimaging, ICP monitoring discontinuation, use of paralytic, hyperosmolar and pentobarbital therapies, neurosurgical interventions, ventilator and CPP adjustments and neurologic prognostication discussions. Retrospective analysis was performed on the association of MMM reporting with initial Glasgow Coma Scale (GCS) and Pediatric Risk of Mortality III (PRISM III) scores, duration of total hospitalization and PICU hospitalization, duration of mechanical ventilation and invasive ICP monitoring, inpatient complications, time with ICP > 20 mmHg, time with cerebral perfusion pressure (CPP) < 40 mmHg and 12-month Glasgow Outcome Scale—Extended Pediatrics (GOSE-Peds) scores. Association of outcomes with MMM reporting was investigated using the Wilcoxon rank-sum test or Fisher’s exact test, as appropriate.ResultsEighty-five children with TBI underwent MMM over 6 years, among which 18 underwent daily MMM reporting over a 21-month period. Clinical decision-making influenced by MMM reporting included timing of neuroimaging (100.0%), ICP monitoring discontinuation (100.0%), timing of extubation trials of surviving patients (100.0%), body repositioning (11.1%), paralytic therapy (16.7%), hyperosmolar therapy (22.2%), pentobarbital therapy (33.3%), provocative cerebral autoregulation testing (16.7%), adjustments in CPP thresholds (16.7%), adjustments in PaCO2 thresholds (11.1%), neurosurgical interventions (16.7%) and neurologic prognostication discussions (11.1%). The implementation of MMM reporting was associated with a reduction in ICP monitoring duration (p = 0.0017) and mechanical ventilator duration (p = 0.0018). No significant differences were observed in initial GCS or PRISM III scores, total hospitalization length, PICU hospitalization length, total complications, time with ICP > 20 mmHg, time with CPP < 40 mmHg, use of tier 2 therapy, or 12-month GOS-E Peds scores.ConclusionImplementation of MMM reporting in pediatric TBI management is feasible and can be impactful in tailoring clinical decisions. Prospective work is needed to understand the impact of MMM and MMM reporting systems on functional outcomes and clinical care efficacy.Supplementary InformationThe online version contains supplementary material available at 10.1007/s12028-021-01190-8.

Very Long-Term Outcomes in Children Admitted in a Disorder of Consciousness After Severe Traumatic Brain Injury

ObjectivesTo investigate functional outcomes and state of consciousness at 1 year and ≥2 years postinjury in children who sustained a traumatic brain injury and were in a disorder of consciousness (DOC), either vegetative state (VS) or minimally conscious state (MCS), upon admission to inpatient rehabilitation. DesignRetrospective chart review. SettingPediatric inpatient rehabilitation unit. ParticipantsChildren aged 2-18 years (N=37) who were admitted to inpatient rehabilitation with admission scores <30 on the Cognitive and Linguistic Scale (CALS). InterventionsNot applicable. Main Outcome MeasuresGlasgow Outcome Scale- Extended, Pediatric Revision (GOS-E Peds), and state of consciousness based on previously established guidelines. ResultsAt admission, 16 children were in VS (43.2%) and 21 (56.8%) were in MCS. Children admitted in VS had a significantly longer time from injury to inpatient rehabilitation admission, lower CALS admission scores, were more likely to be in a DOC ≥28 days, and had greater disability at both follow-up time points. At the 1-year follow-up, 3 patients were in VS, 7 were in MCS, and 27 had emerged from MCS. By the time of the most recent follow-up (≥2y), 2 more patients had emerged from MCS. Across the cohort, GOS-E Peds scores at 1 year ranged from VS (GOS-E Peds, 7) to upper moderate disability (GOS-E Peds, 3). Most patients were functioning in the lower severe disability category (GOS-E Peds, 6) at 1 year (43.2%) and at the time of the most recent follow-up (43.2%). Twenty-seven patients (73.0%) showed stable GOS-E Peds scores between the 2 time points, 6 (16.2%) improved, and 4 (10.8%) were deceased. ConclusionsAlthough a majority of patients emerged from a DOC by 1 year postinjury, most continued to demonstrate notable functional impairment at the 1-year follow-up that persisted to the most recent follow-up. A small subset demonstrated important improvements between 1 year and the most recent follow-up (2 patients emerged, 6 patients showed improvement in GOS-E Peds scores).

Early coagulopathy in children with isolated blunt head injury is associated with mortality and poor neurological outcomes.

Traumatic brain injury (TBI) is the leading cause of long-term disability and death in children and adolescents globally. Long-term adverse outcomes, including physical, cognitive, and behavioral sequelae, have been reported after TBI in a significant number of pediatric patients. In this study the authors sought to investigate the epidemiology of TBI-associated coagulopathy and its association with mortality and poor neurological outcome in a pediatric population with isolated moderate to severe blunt head injury treated at the authors' institution. This retrospective study was conducted in the children's emergency department between January 2010 and December 2016. Children < 18 years old who presented with isolated moderate to severe blunt head injury were included in the study. The authors collected data on patient demographics, clinical presentation, and TBI management. Outcomes studied were death and poor neurological outcome defined by a score of < 7 (death, moderate to severe neurological disability) at 6 months postinjury on the pediatric version of the Glasgow Outcome Scale-Extended (GOS-E Peds). In 155 pediatric patients who presented with isolated moderate to severe blunt head injury, early coagulopathy was observed in 33 (21.3%) patients during the initial blood investigations done in the emergency department. The mean (SD) age of the study group was 7.03 (5.08) years and the predominant mechanism of injury was fall from height (65.2%). The median Abbreviated Injury Scale of the head (AIS head) score was 4 and the median GCS score was 13 (IQR 12-15). TBI-associated coagulopathy was independently associated with GOS-E Peds score < 7 (p = 0.02, adjusted OR 6.07, 95% CI 1.32-27.83). The overall mortality rate was 5.8%. After adjusting for confounders, only AIS head score and hypotension at triage remained significantly associated with TBI-associated coagulopathy. TBI-associated coagulopathy was independently associated with GOS-E Peds score < 7 at 6 months postinjury. Larger prospective studies are needed to investigate the use of TBI-associated coagulopathy to prognosticate these critical clinical outcomes.
