Hemodynamic optimization in severe trauma: a systematic review and meta-analysis.

OBJECTIVE: Severe trauma can be associated with significant hemorrhagic shock and impaired organ perfusion. We hypothesized that goal-directed therapy would confer morbidity and mortality benefits in major trauma. METHODS: The MedLine, Embase and Cochrane Controlled Clinical Trials Register databases were systematically searched for randomized, controlled trials of goal-directed therapy in severe trauma patients. Mortality was the primary outcome of this review. Secondary outcomes included complication rates, length of hospital and intensive care unit stay, and the volume of fluid and blood administered. Meta-analysis was performed using RevMan software, and the data presented are as odds ratios for dichotomous outcomes and as mean differences (MDs) and standard MDs for continuous outcomes. RESULTS: Four randomized, controlled trials including 419 patients were analyzed. Mortality risk was significantly reduced in goal-directed therapy-treated patients, compared to the control group(OR=0.56, 95%CI: 0.34-0.92). Intensive care (MD: 3.7 days 95%CI: 1.06-6.5)and hospital length of stay (MD: 3.5 days,95%CI: 2.75-4.25) were significantly shorter in the protocol group patients.There were no differences in reported total fluid volume or blood transfusions administered. Heterogeneity in reporting among the studies prevented quantitative analysis of complications. CONCLUSION: Following severe trauma, early goal-directed therapy was associated with lower mortality and shorter durations of intensive care unit and hospital stays. The findings of this analysis should be interpreted with caution due to the presence of significant heterogeneity and the small number of the

Idiopathic pulmonary fibrosis associated with pulmonary vein thrombosis: a case report.

BACKGROUND: Pulmonary vein thrombosis represents a potentially fatal disease. This syndrome may clinically mimic pulmonary embolism but has a different investigation strategy and prognosis. Pulmonary vein thrombosis is difficult to diagnose clinically and usually requires a combination of conventionally used diagnostic modalities. CASE PRESENTATION: The authors report a case of a 78-year-old previously healthy female presenting with collapse and shortness of breath. Serum biochemistry revealed acute kidney injury, positive D-dimmer's and increased C reactive protein. Chest radiography demonstrated volume loss in the right lung. The patient was started on antibiotics and also therapeutic doses of low molecular weight heparin. The working diagnosis included community acquired pneumonia & pulmonary embolism. A computed tomography pulmonary angiogram was performed to confirm the clinical suspicions of pulmonary embolism. This demonstrated a thrombus in the pulmonary vein, with associated fibrosis and volume loss of the right lower lobe. A subsequent thrombophilia screen revealed a positive lupus anticoagulant antibody and rheumatoid factor and also decreased anti thrombin III and protein C levels. The urine protein/creatinine ratio was found to be 553 mg/mmol. CONCLUSION: The diagnosis of this patient was therefore of idiopathic pulmonary fibrosis associated with pulmonary vein thrombosis. Whether or not the pulmonary vein thrombosis was a primary cause of the fibrosis or a consequence of it was unclear. There are few data on the management of pulmonary vein thrombosis, but anticoagulation, antibiotics, and, in cases of large pulmonary vein thrombosis, thrombectomy or pulmonary resection have been used.

Otimização hemodinâmica em trauma grave: uma revisão sistemática e metanálise / Hemodynamic optimization in severe trauma: a systematic review and meta-analysis

Objetivo: O trauma grave pode associar-se a ocorrência de importante choque hemorrágico e ao comprometimento da perfusão dos órgãos. Formulamos a hipótese de que o tratamento direcionado por objetivo conferiria benefícios em termos de morbidade e mortalidade, em casos graves de trauma. Métodos: Realizamos uma busca sistemática nas bases de dados MedLine, Embase e Cochrane Controlled Clinical Trials Register com relação a pacientes vítimas de trauma grave. A mortalidade foi o desfecho primário dessa revisão. Os desfechos secundários incluíram taxas de complicações, duração da permanência no hospital e na unidade de terapia intensiva, e o volume de fluidos administrados. A metanálise foi realizada utilizando o programa de computador RevMan, e os dados apresentados são as odds ratios (OR) para desfechos dicotomizados e as diferenças médias e diferenças médias padrão para desfechos contínuos. Resultados: Foram analisados quatro estudos clínicos randomizados e controlados, que incluíram 419 pacientes. O risco de mortalidade foi significantemente reduzido nos pacientes com tratamento direcionado por objetivo, em comparação ao grupo controle (OR=0,56; IC95%: 0,34-0,92). A duração da permanência na unidade de terapia intensiva (DM: 3,7 dias; IC95%: 1,06-6,5) e no hospital (DM: 3,5 dias; IC95%: 2,75-4,25) foi significantemente mais curta ...
