Atención de los pacientes con trauma grave durante los primeros días: evolución entre la urgencia, el pabellón y la unidad de cuidados intensivos / Features of patients with trauma admitted to an emergency room of a general hospital

Background: Trauma is the main cause of death among people aged 5 to 44 years. Aim: To describe features, treatment and evolution of trauma patients admitted to an emergency room. Material and Methods: Adult patients admitted in the emergency department of a public hospital due to severe trauma were studied and followed during their hospital stay. Results: We included 114 patients aged 40 ± 17 years (78%men) with an injury severity score of 21 ± 11. Trauma was penetrating in 43%. Traumatic brain injury (TBI) was the most common diagnosis in 46%. In the emergency room, 8% had hypotension, 5% required vasopressors and 23% required mechanical ventilation. The initial lactate was 3.6 ± 2.9 mmol/L. Sixty-five patients (57%) required emergency surgery. The intraoperative lactate was 3 ± 1.7 mmol/L and 20% required vasopressors. Sixty-four patients (56%) were admitted to the ICU, with APACHEII and SOFA scores of 16 ± 8 and 5 ± 3, respectively. ICU lactate was 3.2±1.5 mmol/L. In the ICU 40% required vasopressors and 63% mechanical ventilation. Thirty two percent had coagulopathy, 43% received transfusions and 10% required massive transfusions. The hospital stay was 13 (6-32) days, being significantly longer in patients with TBI. ICU and hospital mortalities were 12.5 and 18.4% respectively. The only predictor for mortality was the APACHEII score (Hazard Ratio 1.18, 95% confidence intervals 1.03-1.36). Conclusions: APACHE score was a predictor of mortality in this group of patients.

Traumatic Brain Injury Caused by Motor Vehicle Collision and Alcoholism in Piauí

Objectives To determine the relationship between alcohol consumption and the incidence of traumatic brain injury (TBI) with diffuse axonal injury (DAI), determining these indices, checking acquired comorbidities and characterizing the patients by gender, age and race/color, as well as describing the characteristics of the motor vehicle collision (vehicle, period of the day, day of the week and site) in people admitted to an emergency hospital in the city of Teresina, in the state of Piauí, Brazil. Methods We have analyzed the data contained in the medical records of patients admitted with a history of motor vehicle collision and severe TBI in intensive care units, based on the forms provided by the Mobile Emergency Care Service (SAMU, in the Portuguese acronym) in the period between February 28 and November 28, 2013. Results In the period covered by the present study, 200 individuals were analyzed, and 54 (27%) had consumed alcohol; of these 11 had DAI. Of the total sample, 17% (34) presented DAI, however, with unknown data regarding the consumption of alcoholic beverages. Conclusion Considering the data, we observed that the profile of the head trauma patients are brown men, mostly (53.5%) aged between 15 and 30 years. The collisions occurred mostly on weekends and at night (55%), and 89.5% of the crashes involved motorcycles.

Predictors of quality of life after moderate to severe traumatic brain injury / Preditores de qualidade de vida após trauma crânio-encefálico moderado a grave

ABSTRACT Objective To verify correlations between age, injury severity, length of stay (LOS), cognition, functional capacity and quality of life (QOL) six months after hospital discharge (HD) of victims of traumatic brain injury (TBI). Method 50 patients consecutively treated in a Brazilian emergency hospital were assessed at admission, HD and six months after HD. The assessment protocol consisted in Abbreviated Injury Scale, Injury Severity Score, Glasgow Coma Scale (GCS), Revised Trauma Score (RTS), Mini Mental Test, Barthel Index and World Health Organization QOL - Brief. Results Strong negative correlation was observed between LOS and GCS and LOS and RTS. An almost maximal correlation was found between RTS and GCS and functional capacity and GCS at HD. Age and LOS were considered independent predictors of QOL. Conclusion Age and LOS are independent predictors of QOL after moderate to severe TBI.

RESUMO Objetivo Verificar correlações entre idade, gravidade do trauma, tempo de hospitalização (TH), cognição, capacidade funcional e qualidade de vida (QV) seis meses após alta hospitalar (AH) de vítimas de trauma crânio-encefálico (TCE). Método 50 pacientes tratados em um hospital de emergência brasileiro foram avaliados na admissão, AH e seis meses após AH. O protocolo de avaliação consistia em Escala Abreviada de Lesões, Índice de Gravidade de Lesão, Escala de Coma de Glasgow (ECG), Escore de Trauma Revisado (RTS), teste Mini-Mental, Índice de Barthel e Questionário Breve de QV da Organização Mundial de Saúde. Resultados Forte correlação negativa foi observada entre TH e ECG e TH e RTS. Correlação quase máxima foi observada entre RTS e ECG e capacidade funcional e ECG na AH. Idade e TH foram considerados preditores independentes de QV. Conclusão Idade e TH são preditores independentes de QV após TCE moderado e grave.

Fatores relacionados ao prognóstico de vítimas de traumatismo cranioencefálico: uma revisão bibliográfica / Factors associated with prognosis of traumatic brain injury: a literature review

O traumatismo cranioencefálico (TCE) é uma agressão traumática ao cérebro, em consequência de um trauma externo, resultando em alterações cerebrais momentâneas ou permanentes e comprometimento das habilidades cognitivas ou físicas. O presente artigo tem como objetivo apresentar uma revisão bibliográfica sobre os fatores relacionados ao prognóstico de vítimas de TCE. O estudo compreende um levantamento bibliográfico para o conhecimento e melhor abordagem sobre o tema, possibilitando uma reflexão sobre esses fatores. Com base na literatura e análise dos estudos, evidenciou-se que a baixa pontuação na Escala de Coma de Glasgow tem sido um forte indicador de mau prognóstico das vítimas de TCE. Além disso, a influência de fatores como gravidade das lesões, tipo de lesão intracraniana, idade, hipóxia e hipotensão arterial também se apresentou como determinante sobre a evolução dos pacientes e esteve relacionada ao prognóstico de vítimas de TCE. Podemos observar que nos últimos anos se têm aprofundado os estudos no intuito de se buscar os fatores prognósticos para o TCE, e a identificação desses indicadores tem representado um grande avanço na busca de alternativas para orientar o tratamento do paciente e se estimar o resultado final.

Traumatic brain injury is an injury to the brain trauma as a result of external trauma, resulting in momentary or permanent brain changes and impairment of cognitive abilities or physical functioning. This article aims at reviewing the literature on the factors related to the prognosis of traumatic brain injury. The study comprises a literature to the best knowledge and approach to the subject, providing a reflection on these factors. Based on the literature and analysis of the studies showed that the low score on the Glasgow Coma Scale has been a strong indicator of poor prognosis of traumatic brain injury. Furthermore, the influence of factors such as brain injury, severity of injury, type of intracranial injury, age, hypoxia and hypotension were also presented as determinants of the evolution of patients and were related to the prognosis of traumatic brain injury. We observed that in recent years has deepened the studies in order to seek the prognostic factors for traumatic brain injury, where the identification of these indicators has represented a major breakthrough in the search for alternatives to guide patient treatment and to estimate the end result.

The aetiology of head injury in admitted patients in Jamaica / Aspectos etiológicos de la lesión cefálica en pacientes ingresados en Jamaica

This cross-sectional, descriptive study identified 857 head-injured patients who were admitted to the University Hospital of the West Indies (UHWI) over a four-year period. Their median age (IQR) was 28 (16, 45) years and 629 (73.5%) were males. Median length of hospital stay (IQR) was 2 (1, 6) days. Median ICU stay in the intensive care unit (IQR) was 6 (2, 12) days for the 59 (6.9%) patients admitted there. Most patients (73.3%) were admitted with unintentional injuries resulting from road traffic accidents (48.9%), of which passengers were the most commonly affected, and from falls which occurred in 24.4%. Intentional injuries accounted for 26.7% of those admitted, consisting mainly of assaults with blunt objects in 18.0% (154/857). Penetrating injuries were less common, accounting for 67 (7.8%) injuries. Among these, there were 23 gunshot wounds of the head (2.7%). Head injury in admitted patients is mainly due to road traffic accidents, falls and interpersonal violence. Prevention and interventional strategies including education, law enforcement, physical and social engineering must focus on these aetiologies. Current measures are clearly insufficient and more effective strategies are urgently warranted.

Este estudio transversal descriptivo identificó 857 pacientes con lesiones cefálicas, ingresados en el Hospital Universitario de West Indies (UHWI) por un periodo de cuatro años. Su edad mediana (IQR) fue 28 (16, 45) años y 629 (73.5%) eran varones. La longitud mediana de estancia hospitalaria (IQR) fue de 2 (1, 6) días. La estancia mediana en la unidad de cuidados intensivos fue de (IQR) 6 (2, 12) días para los 59 (6.9%) pacientes ingresados allí. La mayoría de los pacientes (73.3%) fueron ingresados con lesiones involuntarias a consecuencia de accidentes de tráfico (48.9%) ­ de los cuales los pasajeros fueron comúnmente los más afectados ­ y de caídas ocurridas en 24.4%. Las lesiones intencionales constituyeron el 26.7% de los casos ingresados, siendo el 18.0% (154/857) producidas principalmente por ataques con objetos contundentes. Las lesiones penetrantes fueron menos comunes, representadas por 67 (7.8%) de las lesiones. De estas, 23 fueron heridas de bala en la cabeza (2.7%). Las lesiones en la cabeza en los pacientes ingresados se debieron principalmente a accidentes de tráfico, caídas y violencia interpersonal. Las estrategias de prevención e intervención ­ incluyendo la educación, la imposición del cumplimiento de la ley, la ingeniería física y social ­ deben centrar su atención en estas etiologías. Las medidas actuales son a las claras insuficientes y se requiere con urgencia estrategias más efectivas

Las lecciones derivadas del ASA Closed Claims Project (ASACCP). Proyecto de la ASA acerca de las razones que promovieron demandas contra anestesiólogos cuyos casos estaban ya archivados (2a parte): La paciente obstétrica. Una actualización / Lessons learned from the ASA Closed Claims Project (ASACCP). ASA Project about the reasons for wich claims against anesthesiologists were rewed in cases that had already been close (part 2): The obstetric patient. An update

El análisis de los últimos casos relacionados con el tema fue publicado en el año 1996 cuando en la base de la ASACCP constaban 3533 demandas terminadas. De éstas, 434 estuvieron relacionadas con la anestesia obstétrica. De las 434 demandas relacionadas con la anestesia obstétrica, 310 correspondieron a la operación cesárea y 124 al parto por vía vaginal con anestesia regional. Las muertes maternas (n=83) y el daño cerebral del recién nacido (n=82) continúan siendo las injurias más frecuentes en las pacientes obtétricas. La muerte materna estuvo más comúnmente relacionada con la anestesia general y con la operación cesárea. A pesar de que el número de muertes maternas consecutivas a la anestesia general se mantuvo estable a través de los años, el número de muertes asociadas a la anestesia regional declinó en forma marcada. Este decremento de muertes maternas bajo anestesia regional ocurrió sobre todo en los años 80, coincidiendo con la prohibición del uso de bupivacaína al 0,75 por ciento. Además, esta declinación se debe, sin duda, a la solución de los problemas creados por la vía aérea, la cual es más difícil de acceder en la mujer embarazada (1:270 en la paciente obstétrica, contra 1:2.230 de la no obstétrica). La necesidad de controlar la vía aérea es crucial para reducir los casos de muerte durante anestesia general. Lo mismo sucede con la anestesia regional cuando la altura del bloqueo es muy elevada o por cualquier otra razón que obligue a convertir una anestesia regional en una general. Siempre existe el temido problema de la aspiración de contenido gástrico, que sigue siendo la primera causa de muerte materna durante la anestesia y casi siempre asociada con una intubación dificultosa o fallida. El daño cerebral del recién nacido se produjo en el 19 por ciento de las demandas estudiadas por la ASACCP. En una Unidad de Cuidados Intensivo de recién nacidos en EE.UU se realizó un estudio retrospectivo, como los estudios de la ASACCP, para analizar el número de demandas relacionadas con los casos internados en dicha unidad. El estudio comprendió el período 1972-1992 durante el cual se produjeron 31 demandas por mala praxis sobre 9367 internaciones, con una incidencia de 0,33 por ciento. Según los autores, la frecuencia de juicios contra los anestesiólogos por problemas vinculados con el recién nacido se incrementó del 0,19 por ciento entre los años 1772-1974 al 0,39 entre 1980 y 1992...
