RESUMEN
Previous reports of mortality and morbidity in pediatric severe traumatic brain injury (TBI) vary considerably, with few population-based studies. Mortality rates from 3-33 % and varying morbidity have been reported, most commonly using the Extended Glasgow Outcome Scale (eGOS). The Lund concept is a treatment algorithm for severe TBI aiming at controlling intracranial pressure (ICP) by reducing cerebral perfusion pressure (CPP). The aim of the present study was to retrospectively assess mortality and morbidity in a population of pediatric TBI treated according to the Lund concept. All cases of severe pediatric TBI (age <18 years) in the southern region of Sweden during 19 years were identified. Patients were treated according to the Lund concept. Mortality, eGOS, ICP, CPP, time in the neurosurgical intensive care unit (NICU), drugs delivered and surgical procedures were recorded. Data were analyzed both by dichotomized outcomes and by ordinal statistics. A total of 135 cases of severe TBI <18 years of age were recorded (incidence 2.0/100000) and 86 patients were admitted to the tertiary NICU. Mortality including all cases was 43% (mortality rate 0.7/100,000) and in NICU 10%. Outcome was good in 60%, moderate in 25%, unfavorable in 15%, with none in a vegetative status. In both dichotomized and ordinal analyses, CPP <40 mm Hg and ICP >15 were associated with poor outcome, supporting current guidelines. However, high CPP also was associated with increased mortality and morbidity, supporting that elevated CPP might increase cerebral edema. In this study, the Lund concept resulted in low mortality and a favorable outcome in a majority of severe pediatric TBI patients; however, randomized controlled trials are warranted to verify this.

BACKGROUND: Traumatic acute subdural hematomas (ASDHs) are associated with high rate of morbidity and mortality, especially in elderly individuals. However, recent reports indicate that the morbidity and mortality rates might have improved. OBJECTIVE: To evaluate postoperative (30-d) mortality in younger vs elderly (≥70 yr) patients with ASDH. Comparing younger and elderly patients, the secondary objectives are morbidity patterns of care and 6 mo outcome according to Glasgow outcome scale (GOS). Finally, in patients with traumatic ASDH, we aim to provide prognostic variables. METHODS: This is a large-scale population-based Scandinavian study including all neurosurgical departments in Denmark and Sweden. All adult (≥18 yr) patients surgically treated between 2010 and 2014 for a traumatic ASDH in Denmark and Sweden will be included. Identification at clinicaltrials.gov is NCT03284190. EXPECTED OUTCOMES: We expect to provide data on potential differences between younger vs elderly patients in terms of mortality and morbidity. We hypothesize that elderly patients selected for surgery have a similar pattern of care as compared with younger patients. We will provide functional outcome in terms of GOS at 6 mo in younger vs elderly patients undergoing ASDH evacuation. Finally, clinical useful prognostic factors for favorable (GOS 4-5) vs unfavorable (GOS 1-3) will be identified. DISCUSSION: An improved understanding of the clinical outcome, treatment and resource allocation, clinical course, and the prognostic factors of traumatic ASDH will allow neurosurgeons to make better treatment decisions.
