Glasgow Coma Scale

O papel da craniotomia descompressiva (CD) no tratamento da hipertensão intracraniana (HIC) refratária ainda não está estabelecido na literatura. Atualmente é recomendada como opção, pois há deficiência de trabalhos classe I ou II que suportem seu emprego. Trabalhos recentes têm avaliado a eficácia da CD quando aplicada precocemente no tratamento da HIC pós traumática. No presente trabalho analisam-se 21 pacientes nos quais a CD foi realizada precocemente. A maioria dos pacientes apresentava traumatismo cranioencefálico grave (Escala de coma glasgow <9) e tomografia de crânio evidenciando tumefação cerebral (brain swelling) ou hematoma subdural agudo. A principal complicação inerente à técnica foi a hidrocefalia (28,5%). Boa reabilitação social ocorreu em 11 pacientes (52,5%). Parece que a CD, quando realizada precocemente, é eficaz no tratamento da HIC refratária, ressaltando-se ainda a necessidade de estudos classe I e II que suportem esta opinião.

Diabetic ketoacidosis in children may cause brain injuries ranging from mild to severe. Whether intravenous fluids contribute to these injuries has been debated for decades. We conducted a 13-center, randomized, controlled trial that examined the effects of the rate of administration and the sodium chloride content of intravenous fluids on neurologic outcomes in children with diabetic ketoacidosis. Children were randomly assigned to one of four treatment groups in a 2-by-2 factorial design (0.9% or 0.45% sodium chloride content and rapid or slow rate of administration). The primary outcome was a decline in mental status (two consecutive Glasgow Coma Scale scores of <14, on a scale ranging from 3 to 15, with lower scores indicating worse mental status) during treatment for diabetic ketoacidosis. Secondary outcomes included clinically apparent brain injury during treatment for diabetic ketoacidosis, short-term memory during treatment for diabetic ketoacidosis, and memory and IQ 2 t...

Surgical evacuation of nontraumatic, supratentorial intracerebral hemorrhage (SICH) is uncommonly performed, and outcomes are generally poor. On the basis of published experimental data and the authors' anecdotal observations, a retrospective chart review study was performed to test the hypothesis that large decompressive craniectomies (DCs), compared with craniotomies, would improve clinical outcomes after surgical evacuation of SICH. For patients with putaminal SICH, DC was associated with a statistically significant improvement in midline shift, compared with craniotomy. Decompressive craniectomies also resulted in a strong trend toward decreased likelihood of poor neurological outcome (modified Rankin Scale score > 3). For patients with lobar SICH, no associations were found between DC or craniotomy and clinical outcomes. For patients selected to undergo surgical evacuation of putaminal SICH, a DC in addition to surgical evacuation of the hematoma might improve outcome.

Background and objectives: Injury to the head is the most common affected body part in pediatric trauma and could be associated with deleterious consequences. It presents a challenge for developing countries since many injuries are preventable and there are few epidemiological data to support injury prevention programs. The current study aimed to determine demographic characteristics, etiology and outcome of head injury in the pediatric population and compare findings to international figures. Design and settings: Retrospective review of consecutive cases registered in major trauma center database, Riyadh, from 2001 to 2009. Patients and methods: The database registry was limited to hospitalized patients following injury. Any head injury in a patient ≤18 years was included. Results: Of 3796 patients identified, 1219 patients (32.1%) suffered head injury (mean age 8.6 years; males 78.4%). Children under 12 years comprised 66.3%. Motor vehicle crash (MVC) was the commonest cause (34.2%), followed by pedestrian injury (30.3%) and falls (28.4%). When stratified by age, falls (45.6%) were the most common etiology under 6 years while MVC was the leading cause in high school students (74.4%). The latter group had the lowest mean (SD) Glascow coma scale scores ( 8.58 [4.7]), highest mean injury severity scale scores (23.4 [21]), highest rate of craniotomy (7%) and highest mortality (20%). Conclusion: One third of pediatric trauma requiring hospital admission suffered head injury. Preschoolers and elementary school students were mostly affected. The striking incidence of pedestrian and fall injuries call for organized national prevention programs. Additionally, more attention should be directed to reduce MVC among high school students given their comparative high rate of severe injuries and deaths following trauma.

Intelligence tests are commonly administered to children following moderate-to-severe traumatic brain injury (TBI). The Reynolds Intellectual Assessment Scales (RIAS) is a recently developed measure of intellectual ability that has a number of appealing features for assessing individuals with brain damage, but as yet has little validity information when applied to children with TBI or other forms of brain injury. It is therefore unclear whether RIAS scores are sensitive to brain injury and how they compare to older more well-established tests such as the Wechsler scales. The current article reports two studies that examine these matters in youth with TBI. The first study examined sensitivity of the RIAS to TBI in 110 children. Results indicated the TBI sample performed significantly worse compared with the standardization sample on all RIAS index scores. The second study included 102 children who were administered either the RIAS, Wechsler Intelligence Scale for Children-Third Editi...

raumatic brain injury (TBI) is a leading cause of mortality and morbidity in the world's population, especially those under age 44. 1 In the United States alone, the cost of head trauma has been estimated to be over 40 billion dollars an- nually. 2 The National Center for Injury Prevention and Con- trol has estimated that approximately 2% of the
