Objetivo: Comparar a gravidade das lesões e do trauma mensurada pelas versões da Abbreviated Injury Scale 1998 e 2005 e verificar a mortalidade nos escores Injury Severity Score e New Injury Severity Score nas duas versões.Método: Estudo transversal e retrospectivo analisou lesões de pacientes de trauma, de três hospitais universitários do município de São Paulo, Brasil. Cada lesão foi codificada com Abbreviated Injury Scale 1998 e 2005. Os testes estatísticos aplicados foram Wilcoxon, McNemar-Bowker, Kappa e teste Z.Resultados: A comparação das duas versões resultou em discordância significante de escores em algumas regiões corpóreas. Com a versão 2005 os níveis de gravidade da lesão e do trauma foram significantemente reduzidos e a mortalidade foi mais elevada em escores mais baixos. Conclusão: Houve redução da gravidade da lesão e do trauma e alteração no percentual de mortalidade com o uso da Abbreviated Injury Scale 2005.





Rehabilitation outcomes for orthopaedic trauma individuals as measured by the INTERMED.

PURPOSE: Bio-psychosocial characteristics of patients after orthopaedic traumas may be a strong predictor of poor outcome. The objective of this prospective study was to assess whether the INTERMED, a measure of bio-psychosocial complexity, identifies complex inpatients during rehabilitation including vocational aspects with a poor outcome 1 year after discharge. METHOD: At entry, the INTERMED scores of 118 inpatients were used to assign patients to the high or low complexity group. A questionnaire evaluated 1 year after discharge whether patients: (1) returned to work, (2) still have therapies, (3) take psychoactive drugs, (4) take medication against pain and (5) were satisfied with vocational therapy. Univariate logistic regressions identified which variables predict INTERMED case complexity during hospitalisation as well as predictors (i.e. INTERMED case complexity, French as preferred language, duration of the disability, accident at work, work qualification, severity of the injury, psychiatric co-morbidities, pain) of the five measured outcomes 1 year after discharge. RESULTS: During hospitalisation, the high complexity group was associated with a high prevalence of psychiatric co-morbidities, a higher level of pain and a weaker perception of treatment effects. One year after discharge, the INTERMED was the sole variable to predict all outcomes. CONCLUSION: The INTERMED identifies complex patients during vocational rehabilitation after orthopaedic trauma and is a good predictor of poor outcome 1 year after discharge.

Association between perineal trauma and pain in primiparous women

Objective To identify the association between perineal trauma and pain in 473 primiparous women. Method Cross-sectional study in which pain was measured by the numerical pain scale (0 to 10 - 0 being no pain and 10 maximal pain). Results The prevalence and mean intensity of pain were 33.0% and 4.7 points (standard deviation = 2.0) in the numeric scale, respectively. Episiotomy represented the most frequent trauma (46.7%). The occurrence and intensity of the pain were associated with perineal trauma and postpartum time. Having perineal trauma tripled the chance of pain. Each hour elapsed following the birth reduced the chance of pain by 4.8%. Conclusion Primiparous women are subject to a high frequency of perineal trauma, with episiotomy being the most prominent. Perineal pain affects approximately one-third of primiparous women and is associated with the postpartum time and perineal traumas.

Trauma in the elderly caused by traffic accident: integrative review

OBJECTIVE To describe the scientific knowledge produced about trauma in the elderly caused by traffic accidents in healthcare area studies. METHODS Integrative review of studies from 2003 to 2013 searched in LILACS, SciELO, PubMed and CINHAL databases. We used combination of the descriptors injuries, wounds and accidents, in English, Portuguese and Spanish languages. RESULTS 32 studies were selected. In the thematic analysis, three categories emerged: epidemiological data from traffic accidents involving elderly; traffic accidents with elderly pedestrians; and trauma care in the elderly. We observed increased incidence of trauma in most countries and pedestrians represented a large part of the victims. Among these, the elderly are the most vulnerable group. CONCLUSION Studies showed that trauma care in the elderly need protocols and professionals with training in gerontology specialized in trauma care services.

Vacuum assisted venous drainage does not increase trauma to blood cells.

Although gravity drainage has been the standard technique for cardiopulmonary bypass (CPB), the development of min imally invasive techniques for cardiac surgery has renewed interest in using vacuum assisted venous drainage (VAVD) Dideco (Mirandola, Italy) has modified the D903 Avant oxygenator to apply a vacuum to its venous reservoir. The impact of VAVD on blood damage with this device is analyzed. Six calves (mean body weight, 71.3 +/- 4.1 kg) were con nected to CPB by jugular venous and carotid arterial cannu lation, with a flow rate of 4-4.51 L/min for 6 h. They were assigned to gravity drainage (standard D903 Avant oxygen ator, n = 3) or VAVD (modified D903 Avant oxygenator, n = 3). The animals were allowed to survive for 7 days. A standard battery of blood samples was taken before bypass, throughout bypass, and 24 h, 48 h, and 7 days after bypass. Analysis of variance was used for repeated measurements. Thrombocyte and white blood cell counts, corrected by hematocrit and normalized by prebypass values, were not significantly different between groups throughout all study periods. The same holds true for hemolytic parameters (lactate dehydrogenase [LDH] and plasma hemoglobin). Both peaked at 24 hr in the standard and VAVD groups: LDH, 2,845 +/- 974 IU/L vs. 2,537 +/- 476 IU/L (p = 0.65), respectively; and plasma hemoglobin, 115 +/- 31 mg/L vs. 89 +/- 455 mg/L (p = 0.45), respectively. In this experimental setup with prolonged perfusion time, VAVD does not increase trauma to blood cells in comparison with standard gravity drainage.

RESUMO Objetivo Identificar o padrão de intervenções de enfermagem realizadas em vítimas de trauma nas primeiras 24 horas de internação na Unidade de Terapia Intensiva (UTI). Método Estudo prospectivo, realizado na UTI de um hospital em São Paulo, Brasil. O instrumento Nursing Activities Score (NAS) foi utilizado para identificar as intervenções de enfermagem. Resultados A casuística foi composta por 200 pacientes, a maioria homens, com idade média de 40,7 anos, vítimas de acidentes de transporte. A média do NAS foi de 71,3% e o padrão de intervenções de enfermagem identificado incluiu as atividades de monitorização e controles; investigações laboratoriais; medicação, exceto drogas vasoativas; procedimentos de higiene; cuidados com drenos; mobilização e posicionamento; suporte e cuidado aos familiares e pacientes; tarefas administrativas e gerenciais; suporte respiratório; cuidado com vias aéreas artificiais; e tratamento para melhora da função pulmonar. Nas intervenções de monitorização e mobilização, houve a necessidade de cuidados além do normalmente requerido por pacientes de UTI. Conclusão Os resultados desta pesquisa trazem importantes contribuições para o planejamento de ações que visem a capacitação e o dimensionamento da equipe de enfermagem na unidade crítica.

Desempenho dos ajustes do Trauma and Injury Severity Score (TRISS): revisão integrativa

RESUMO Objetivo identificar estudos que realizaram ajustes na equação do Trauma and InjurySeverity Score (TRISS) e compararam a capacidade discriminatória da equação modificada com a original. Método Revisão integrativa de pesquisas publicadas entre 1990 e 2014 nas bases de dados LILACS, MEDLINE, PubMed e SciELO utilizando-se a palavra TRISS. Resultados foram incluídos 32 estudos na revisão. Dos 67 ajustes de equações do TRISS identificados, 35 (52,2%) resultaram em melhora na acurácia do índice para predizer a probabilidade de sobrevida de vítimas de trauma. Ajustes dos coeficientes do TRISS à população de estudo foram frequentes, mas nem sempre melhoraram a capacidade preditiva dos modelos analisados. A substituição de variáveis fisiológicas do Revised Trauma Score (RTS) e modificações do Injury Severity Score (ISS) na equação original tiveram desempenho variado. A mudança na forma de inclusão da idade na equação, assim como a inserção do gênero, comorbidades e mecanismo do trauma apresentaram tendência de melhora do desempenho do TRISS. Conclusão Diferentes propostas de ajustes no TRISS foram identificadas nesta revisão e indicaram, principalmente, fragilidades do RTS no modelo original e necessidade de alteração da forma de inclusão da idade na equação para melhora da capacidade preditiva do índice.

Pancreatic Trauma in Children

Objectives and Study: To document the demographics, mechanisms and outcome of traumatic pancreatitis in children at a single large tertiary referral centre in Australia. Methods: We undertook a 10-year retrospective audit of children admitted to the Royal Children's Hospital [RCH], Melbourne, Australia with a hospital coded diagnosis which included pancreatic injury between 1993 and 2002. Data included patient demographics, source of admission, mechanism of injury, pancreatic complications, associated injuries, Intensive Care Unit [ICU] admission, results of any operative findings, results of any acute computed tomography (CT) and/or ultrasound (US) imaging of pancreas, selected laboratory findings and length of stay. Results: We identified two distinct groups of patients in the 91 documented cases of pancreatic trauma (median age 8.0 yr, range 0.6-15.8 yr; M:F 2.5:1.0). Fifty-nine had a history of abdominal trauma and elevated serum lipase but no CT or ultrasound evidence of pancreatic injury (Group A). Thirty-two had a history of abdominal trauma, elevated serum lipase but also had CT scan and/or ultrasound evidence of pancreatic injury[Group B]. Patients with ''less severe'' injury based on normal imaging had a lower initial lipase level [Group A, median 651 U/L (interquartile range 520 - 1324) vs, Group B, 1608 U/L (interquartile range 680-3526); P = 0.005] and shorter admission time [Group A, 9.0 days (interquartile range 5.5-15.5) vs Group B, 13.4 days (interquartile range 6.8 - 23.8), P = 0.04]. There were no differences with respect to mortality [Group A, 13.5 % vs Group B, 12.5 %] but patients with evidence of injury on imaging were more likely to have surgical intervention [P = 0.0001]. The single most important overall cause of pancreatic trauma was involvement in a motor vehicle accident as a passenger or pedestrian. However, in children with high-grade ductal injury, bicycle handlebar injuries were most common. Associated injuries were common in both groups. Conclusion: Significant pancreatic injury can occur in the absence of abnormality on medical imaging. Pancreatic trauma commonly occurs in the context of multiple injuries after motor vehicle accidents in children and bicycle handlebar injuries, especially in boys. Most children can be treated conservatively, with surgical intervention being limited to high-grade ductal injury.

Sports-related chronic repetitive head trauma as a cause of pituitary dysfunction.

Traumatic brain injury (TBI) is recognized as a cause of hypopituitarism even after mild TBI. Although over the past decade, a growing body of research has detailed neuroendocrine changes induced by TBI, the mechanisms and risk factors responsible for this pituitary dysfunction are still unclear. Around the world, sports-especially combative sports-are very popular. However, sports are not generally considered as a cause of TBI in most epidemiological studies, and the link between sports-related head trauma and hypopituitarism has not been investigated until recently. Thus, there is a paucity of data regarding this important concern. Because of the large number of young sports participants with near-normal life expectancy, the implications of undiagnosed or untreated postconcussion pituitary dysfunction can be dramatic. Understanding the pathophysiological mechanisms and risk factors of hypopituitarism caused by sports injuries is thus an important issue that concerns both medical staff and sponsors of sports. The aim of this paper was to summarize the best evidence for understanding the pathophysiological mechanisms and to discuss the current data and recommendations on sports-related head trauma as a cause of hypopituitarism.

INTERMED predicts non-return to work in an occupational rehabilitation setting for individuals with orthopaedic trauma-Part I

Introduction.- Knowledge of predictors of an unfavourable outcome, e.g. non-return to work after an injury enables to identify patients at risk and to target interventions for modifiable predictors. It has been recently shown that INTERMED; a tool to measure biopsychosocial complexity in four domains (biologic, psychologic, social and care, with a score between 0-60 points) can be useful in this context. The aim of this study was to set up a predictive model for non-return to work using INTERMED in patients in vocational rehabilitation after orthopaedic injury.Patients and methods.- In this longitudinal prospective study, the cohort consisted of 2156 consecutively included inpatients with orthopaedic trauma attending a rehabilitation hospital after a work, traffic or sport related injury. Two years after discharge, a questionnaire regarding return to work was sent (1502 returned their questionnaires). In addition to INTERMED, 18 predictors known at baseline of the rehabilitation were selected based on previous research. A multivariable logistic regression was performed.Results.- In the multivariate model, not-returning to work at 2 years was significantly predicted by the INTERMED: odds-ratio (OR) 1.08 (95% confidence interval, CI [1.06; 1.11]) for a one point increase in scale; by qualified work-status before the injury OR = 0.74, CI (0.54; 0.99), by using French as preferred language OR = 0.60, CI (0.45; 0.80), by upper-extremity injury OR = 1.37, CI (1.03; 1.81), by higher education (> 9 years) OR = 0.74, CI (0.55; 1.00), and by a 10 year increase in age OR = 1.15, CI (1.02; 1.29). The area under the receiver-operator-characteristics curve (ROC)-curve was 0.733 for the full model (INTERMED plus 18 variables).Discussion.- These results confirm that the total score of the INTERMED is a significant predictor for return to work. The full model with 18 predictors combined with the total score of INTERMED has good predictive value. However, the number of variables (19) to measure is high for the use as screening tool in a clinic.

Influence of early antioxidant supplements on clinical evolution and organ function in critically ill cardiac surgery, major trauma, and subarachnoid hemorrhage patients.

INTRODUCTION: Oxidative stress is involved in the development of secondary tissue damage and organ failure. Micronutrients contributing to the antioxidant (AOX) defense exhibit low plasma levels during critical illness. The aim of this study was to investigate the impact of early AOX micronutrients on clinical outcome in intensive care unit (ICU) patients with conditions characterized by oxidative stress. METHODS: We conducted a prospective, randomized, double-blind, placebo-controlled, single-center trial in patients admitted to a university hospital ICU with organ failure after complicated cardiac surgery, major trauma, or subarachnoid hemorrhage. Stratification by diagnosis was performed before randomization. The intervention was intravenous supplements for 5 days (selenium 270 microg, zinc 30 mg, vitamin C 1.1 g, and vitamin B1 100 mg) with a double-loading dose on days 1 and 2 or placebo. RESULTS: Two hundred patients were included (102 AOX and 98 placebo). While age and gender did not differ, brain injury was more severe in the AOX trauma group (P = 0.019). Organ function endpoints did not differ: incidence of acute kidney failure and sequential organ failure assessment score decrease were similar (-3.2 +/- 3.2 versus -4.2 +/- 2.3 over the course of 5 days). Plasma concentrations of selenium, zinc, and glutathione peroxidase, low on admission, increased significantly to within normal values in the AOX group. C-reactive protein decreased faster in the AOX group (P = 0.039). Infectious complications did not differ. Length of hospital stay did not differ (16.5 versus 20 days), being shorter only in surviving AOX trauma patients (-10 days; P = 0.045). CONCLUSION: The AOX intervention did not reduce early organ dysfunction but significantly reduced the inflammatory response in cardiac surgery and trauma patients, which may prove beneficial in conditions with an intense inflammation.
