OBJECTIVE: Brain Injury Guidelines (BIG) have been established to guide management related to TBI in adults. Here, BIG criteria were applied to pediatric TBI patients to evaluate reliability, safety, and resource utilization.
METHODS: A retrospective study was performed on all pediatric TBI patients aged 18 years or younger from January 2012 to July 2023 at a Level 1 Pediatric Trauma Center. The severity of TBI (BIG 1/2/3) was rated by review of initial cranial imaging by two independent observers. Inter-observer reliability was assessed. Predictions based on BIG criteria regarding repeat cranial imaging, ICU admission, and neurosurgical consultation were compared with observations from the cohort. Outcome data was collected, including neurosurgical intervention and mortality rate.
RESULTS: Three hundred fifty-nine patients were included with mean age of 5.3 years. Injury severity included 44 BIG 1 (12.2%), 170 BIG 2 (47.4%), and 145 BIG 3 injuries (40.4%). Inter-rater reliability was 96.4%. Neurosurgical consultation was obtained in all patients, though only predicted by guidelines in 40.4%. Repeat imaging was obtained in 166 BIG 1/2 patients, with an average of 1.3 CT scans and 0.8 MRIs/rapid MRIs per patient. ICU was utilized in 104 (77.6%) patients not recommended per BIG criteria. Ultimately, 37 patients, all BIG 3, required neurosurgical intervention; no neurosurgical interventions were required in those classified as BIG 1/2.
CONCLUSIONS: BIG criteria can be applied to pediatric TBI with high inter-observer reliability and without formal neurosurgical training. Retrospective application of BIG predicted fewer imaging studies, ICU admissions, and neurosurgical consults without overlooking patients requiring neurosurgical intervention.

OBJECTIVE: To document current practice and develop consensus recommendations for the assessment and treatment of paroxysmal sympathetic hyperactivity (PSH) during rehabilitation after severe acquired brain injury.
METHODS: Delphi consensus process with three rounds, based on the Guidance on Conducting and REporting DElphi Studies (CREDES) guidelines, led by three convenors (the authors) with an expert panel. Round 1 was exploratory, with consensus defined before round 2 as agreement of at least 75% of the panel.
METHODS: A working group within the Nordic Network for Neurorehabilitation.
UNASSIGNED: Twenty specialist physicians, from Sweden (9 participants), Norway (7) and Denmark (4), all working clinically with patients with severe acquired brain injury and with current involvement in clinical decisions regarding PSH.
RESULTS: Consensus was reached for 21 statements on terminology, assessment and principles for pharmacological and non-pharmacological treatment, including some guidance on specific drugs. From these, an algorithm to support clinical decisions at all stages of inpatient rehabilitation was created.
CONCLUSIONS: Considerable consensus exists in the Nordic countries regarding principles for PSH assessment and treatment. An interdisciplinary approach is needed. Improved documentation and collation of data on treatment given during routine clinical practice are needed as a basis for improving care until sufficiently robust research exists to guide treatment choices.

BACKGROUND: Emergency Department (ED) Observation Units (OU) can provide safe, effective care for low risk patients with intracranial hemorrhages. We compared current ED OU use for patients with subdural hematomas (SDH) to the validated Brain Injury Guidelines (BIG) to evaluate the potential impact of implementing this risk stratification tool.
METHODS: Retrospective cohort of patients ≥18 years old with SDH of any cause from 2014 to 2020 to evaluate for potential missed OU cases. Missed OU cases were defined as patients with an initial Glasgow Coma Score (GCS) of 15 with hospital length of stays (LOS) <2 days, who did not meet the composite outcome and were not cared for in the OU or discharged from the ED. Composite outcome included in-hospital death or transition to hospice care, neurosurgical intervention, GCS decline, and worsening SDH size. Secondary outcomes were whether application of BIG would increase ED OU use or reduce CT use.
RESULTS: 264 patients met inclusion criteria over 5.3 year study timeframe. Mean age was 61 years (range 19-93) and 61.4% were male. SDH were traumatic in 76.9% and 60.2% of the cohort had additional injuries. The admission rate was 81.4% (n = 215). Fourteen (6.5%) missed OU cases were identified (2.6/year). Retrospective application of BIG resulted in 82.6% (n = 217) at BIG 3, 10.2% (n = 27) at BIG 2 and 7.6% (n = 20) at BIG 1. Application of BIG would not have decreased admission rates (82.6% BIG 3) and BIG 1 and 2 admissions were often for medical co-morbidities. The composite outcome was met in 50% of BIG 3, 22% of BIG 2, and no BIG 1 patients.
CONCLUSIONS: In a level 1 trauma center with an established observation unit, current clinical care processes missed very few patients who could be discharged or placed in ED OU for SDH. Hospital admissions in BIG 1/2 were driven by co-morbidities and/or injuries, limiting applicability of BIG to this population.

BACKGROUND: Mild traumatic brain injury is common in children and it can be challenging to accurately identify those in need of urgent medical intervention. The Scandinavian guidelines for management of minor and moderate head trauma in children, the Scandinavian Neurotrauma Committee guideline 2016 (SNC16), were developed to aid in risk stratification and decision-making in Scandinavian emergency departments (EDs). This guideline has been validated externally with encouraging results, but internal validation in the intended healthcare system is warranted prior to broad clinical implementation.
OBJECTIVE: We aim to validate the diagnostic accuracy of the SNC16 to predict clinically important intracranial injuries (CIII) in paediatric patients suffering from blunt head trauma, assessed in EDs in Sweden and Norway.
METHODS: This is a prospective, pragmatic, observational cohort study. Children (aged 0-17 years) with blunt head trauma, presenting with a Glasgow Coma Scale of 9-15 within 24 hours postinjury at an ED in 1 of the 16 participating hospitals, are eligible for inclusion. Included patients are assessed and managed according to the clinical management routines of each hospital. Data elements for risk stratification are collected in an electronic case report form by the examining doctor. The primary outcome is defined as CIII within 1 week of injury. Secondary outcomes of importance include traumatic CT findings, neurosurgery and 3-month outcome. Diagnostic accuracy of the SNC16 to predict endpoints will be assessed by point estimate and 95% CIs for sensitivity, specificity, likelihood ratio, negative predictive value and positive predictive value.
BACKGROUND: The study is approved by the ethical board in both Sweden and Norway. Results from this validation will be published in scientific journals, and a tailored development and implementation process will follow if the SNC16 is found safe and effective.
BACKGROUND: NCT05964764.

With the significant increase in the use of extracorporeal membrane oxygenation in patients with severe respiratory failure, cardiogenic shock, and cardiopulmonary resuscitation, complications related to extracorporeal membrane oxygenation are increasingly being taken seriously. Cerebral injury is one of the most serious complications during extracorporeal membrane oxygenation treatment, and is an important factor affecting the hospital mortality rate and long-term quality of life. Due to the use of analgesics, sedatives, and muscle relaxants interfering with neurological physical examination results, cerebral injury that occurs during extracorporeal membrane oxygenation therapy is not easily detected in a timely manner. Therefore, bedside cerebral monitoring has important value in quickly detecting cerebral injury in patients with extracorporeal membrane oxygenation and providing early intervention guidance. Therefore, Extracorporeal Life Support Professional Committee of Chinese Medical Doctor Association organized relevant experts across the country to develop the\"Chinese expert consensus on cerebral monitoring in patients with extracorporeal membrane oxygenation\", this expert consensus is based on the pathological and physiological mechanisms of cerebral injury in patients with extracorporeal membrane oxygenation. It is based on the current application status of cerebral monitoring technologies such as neurological physical examination, plasma brain injury biomarkers, brain imaging, intracranial pressure, cerebral blood flow, brain oxygen, electroencephalogram, and somatosensory evoked potential. Combining the special clinical application scenarios of extracorporeal membrane oxygenation and integrating the latest evidence-based medical evidence, we have formed 15 consensus recommendations which can be referenced by professionals in critical care medicine, neurology, cardiovascular disease, respiratory and critical care, emergency medicine, and other fields. Given the particularity, complexity, and individual differences of critically ill patients, the recommendations formed by this expert consensus need to implement personalized strategies.

Hyponatremia is a common electrolyte abnormality affecting hospitalized patients.1 It is an independent predictor for mortality and is associated with increased length of hospital stay and higher costs. The most serious potential complication is hyponatremic encephalopathy, a medical emergency that can result in death or irreversible brain injury if inadequately treated.2 Hypertonic saline is a safe and effective means of correcting hyponatremia.2-4 A rare yet serious complication from excessive correction of chronic hyponatremia is the development of cerebral demyelination.

UNASSIGNED: The Excellence in Prehospital Injury Care (EPIC) study demonstrated improved survival in patients with severe traumatic brain injury (TBI) following implementation of the prehospital treatment guidelines. The impact of implementing these guidelines in the subgroup of patients who received positive pressure ventilation (PPV) is unknown.
UNASSIGNED: To evaluate the association of implementation of prehospital TBI evidence-based guidelines with survival among patients with prehospital PPV.
UNASSIGNED: The EPIC study was a multisystem, intention-to-treat study using a before/after controlled design. Evidence-based guidelines were implemented by emergency medical service agencies across Arizona. This subanalysis was planned a priori and included participants who received prehospital PPV. Outcomes were compared between the preimplementation and postimplementation cohorts using logistic regression, stratified by predetermined TBI severity categories (moderate, severe, or critical). Data were collected from January 2007 to June 2017, and data were analyzed from January to February 2023.
UNASSIGNED: Implementation of the evidence-based guidelines for the prehospital care of patient with TBI.
UNASSIGNED: The primary outcome was survival to hospital discharge, and the secondary outcome was survival to admission.
UNASSIGNED: Among the 21 852 participants in the main study, 5022 received prehospital PPV (preimplementation, 3531 participants; postimplementation, 1491 participants). Of 5022 included participants, 3720 (74.1%) were male, and the median (IQR) age was 36 (22-54) years. Across all severities combined, survival to admission improved (adjusted odds ratio [aOR], 1.59; 95% CI, 1.28-1.97), while survival to discharge did not (aOR, 0.94; 95% CI, 0.78-1.13). Within the cohort with severe TBI but not in the moderate or critical subgroups, survival to hospital admission increased (aOR, 6.44; 95% CI, 2.39-22.00), as did survival to discharge (aOR, 3.52; 95% CI, 1.96-6.34).
UNASSIGNED: Among patients with severe TBI who received active airway interventions in the field, guideline implementation was independently associated with improved survival to hospital admission and discharge. This was true whether they received basic airway interventions or advanced airways. These findings support the current guideline recommendations for aggressive prevention/correction of hypoxia and hyperventilation in patients with severe TBI, regardless of which airway type is used.

Traumatic brain injury (TBI) is associated with hypopituitarism with a variable incidence, depending on the time and methods used to diagnosis, and on factors related to the trauma, such as its severity, its anatomical location and the drugs used in the acute phase. The pituitary gland can be damaged directly by the impact or secondary to factors such as ischemia, inflammation, excitotoxicity or immunity. In acute phases ACTH deficiency is the most relevant, since failure to detect and treat it can compromise the patient\'s life. Clinical manifestations are typical of each hormone deficient axes, although the combination hypopituitarism-trauma has been associated with cognitive deterioration, worse metabolic profile and greater impairment of quality of life. One of the clinical challenges is to determine which patients benefit from a systematic hormonal evaluation, and therefore from hormone replacement, and what is the appropriate time to do so and the most suitable diagnostic methods.

BACKGROUND: The Brain Injury Guidelines (BIG) stratify patients by traumatic brain injury (TBI) severity to provide management recommendations to reduce health care resource burden but mandates that patients on anticoagulation (AC) are allocated to the most severe tertile (BIG 3). We sought to analyze TBI patients on AC therapy using a modified BIG model to determine if this population can offer further opportunity for safe reductions in health care resource utilization.
METHODS: Patients 55 years or older on AC with traumatic intracranial hemorrhage (ICH) from two centers were retrospectively stratified into BIG 1 to 3 risk groups using modified BIG criteria excluding AC as a criterion. Intracranial hemorrhage progression, neurosurgical intervention (NSI), death, and worsened discharge status were compared.
RESULTS: A total of 221 patients were included, with 23%, 29%, and 48% classified as BIG 1, BIG 2, and BIG 3, respectively. The BIG 3 cohort had a higher rate of AC reversal agents administered (66%) compared with the BIG 1 (40%) and BIG 2 (54%) cohorts ( p < 0.01), as well as ICH progression discovered on repeat head computed tomography (56% vs. 38% vs. 26%, respectively; p < 0.001). No patients in the BIG 1 and 2 cohorts required NSI. No patients in BIG 1 and 3% of patients in BIG 2 died secondary to the ICH. In the BIG 3 cohort, 16% of patients required NSI and 26% died. Brain Injury Guidelines 3 patients had 15 times the odds of mortality compared with BIG 1 patients ( p < 0.01).
CONCLUSIONS: The AC population had higher rates of ICH progression than the BIG literature, but this did not lead to more NSI or mortality in the lower tertiles of our modified BIG protocol. If the modified BIG used the original tertile management on our population, then NS consultation may have been reduced by up to 52%. These modified criteria may be a safe opportunity for further health care resource and cost savings in the TBI population.
METHODS: Prognostic and Epidemiological; Level IV.
