Trauma torácico: análise de 124 pacientes submetidos à toracotomia / Thoracic trauma: analysis of 124 patients who underwent thoracotomy

OBJETIVO: Analisar os pacientes submetidos à toracotomia para o tratamento de traumatismo torácico. MÉTODOS: Estudo retrospectivo por meio da análise de prontuários nos dois principais hospitais de referência para trauma em adultos desta cidade, por um período de cinco anos, interessando dados epidemiológicos, agente causal, indicações, tipo de incisão, classificação do escore anatômico do trauma, fatores prognósticos e a mortalidade. RESULTADOS: Foi analisado neste estudo 124 pacientes submetidos à toracotomia com idade média de 28 anos, tendo como o agente causal mais incidente a arma branca (68 por cento dos casos). A principal indicação da toracotomia foi hemotórax maciço com 50,7 por cento dos casos, seguido de choque cardiogênico ou hipovolêmico com 48,4 por cento. Ocorreram 28 óbitos (20,6 por cento), sendo que os pacientes com lesões de veia cava (cinco pacientes) e aorta (dois pacientes) tiveram uma mortalidade de 100 por cento. Observou-se uma maior mortalidade em pacientes com escore anatômico do trauma superior a 14 (p=0,004) e maior quantidade de sangue transfundido (p=0,090). CONCLUSÃO: O perfil do paciente que foi vítima de traumatismo torácico e submetido à toracotomia exploradora é o seguinte: jovem, do sexo masculino e vítima de trauma por arma branca. Os fatores que mais contribuíram para o êxito letal foram o elevado escore anatômico do trauma e a associação com lesões vasculares importantes, como da artéria aorta e veia cava.

OBJECTIVE: To analyze patients who underwent thoracotomy for the treatment of chest trauma in the City of Manaus. METHODS: We performed a retrospective study through analyzed records in the two main reference hospitals for trauma adults in this city during a period of 5 years. We considered for this study the epidemiological data, causal agent, type of incision, anatomical classification score of trauma, prognostic factors and mortality. RESULTS: We analyzed 124 patients who underwent thoracotomy with a mean age of 28 years. Stab wounds were the most common casual agent (68 percent). The main indication for thoracotomy was massive hemothorax with 50.7 percent of cases, followed by cardiogenic or hypovolemic shock with 48.4 percent. There were 28 deaths (20.6 percent). Patients with vena cava injuries (5 patients) and aorta lesions (2 patients) had 100 percent mortality rate. There was a higher mortality in patients with major index of trauma (p = 0004), and largest quantity of blood transfused (p = 0090). CONCLUSION: Thoracic trauma patients submitted to exploratory thoracotomy were young, males and victims of stab wound trauma. The most contributing death factors were the lethal anatomical score, more than 15 points, and the association with major vascular lesions, as the aorta and vena cava.

Prevalence of pectus carinatum and pectus excavatum in students in the city of Manaus, Brazil.

OBJECTIVE: To determine the prevalence of congenital anterior chest wall deformities in 11- to 14-year-old students. METHODS: Students participating in the study were recruited from public schools in the city of Manaus, Brazil. The statistically significant sample (precision, 1%; 95% CI) comprised 1,332 students. Pectus deformities were identified by physical examination of the chest, and the individuals with one of these deformities completed a questionnaire regarding heredity and symptoms resulting from the chest abnormality. RESULTS: The mean age of the participants was 11.7 years. The prevalence of pectus abnormalities was 1.95% (pectus excavatum: 1.275%; pectus carinatum: 0.675%). Of the 26 students with a pectus deformity, 17 (65.4%) had pectus excavatum, and 18 (69.2%) were male. Concomitant scoliosis was observed in 3 cases (11.5%). A family history of pectus was reported by 17 students (65.4%), and 17 (65.4%) reported chest pain, dyspnea or palpitations. CONCLUSIONS: In this study, the prevalence of pectus deformities (1.95%) was lower than that reported in other studies conducted in Brazil (3.6-4.9%) but was higher than that reported in the literature (mean, 1%).

Prevalência de pectus carinatum e pectus excavatum em escolares de Manaus / Prevalence of pectus carinatum and pectus excavatum in students in the city of Manaus, Brazil

OBJETIVO: Determinar a prevalência das deformidades congênitas da parede torácica anterior em escolares de 11 a 14 anos. MÉTODOS: Participaram do estudo escolares da rede estadual de ensino da cidade de Manaus (AM). Para a composição de uma amostra estatisticamente significativa, com precisão de 1 por cento e IC95 por cento, foram incluídos 1.332 escolares. A deformidade pectus foi identificada através de exame físico do tórax, e os indivíduos com esta deformidade responderam a um questionário com questões sobre hereditariedade e sintomatologia decorrente da anomalia torácica. RESULTADOS: A idade média dos participantes foi de 11,7 anos. A prevalência da deformidade pectus foi de 1,95 por cento (pectus excavatum: 1,275 por cento; pectus carinatum: 0,675 por cento). Dos 26 escolares com deformidades pectus, 17 (65,4 por cento) tinham pectus excavatum, e 18 (69,2 por cento) eram do sexo masculino. Houve associação com a escoliose em 3 casos (11,5 por cento). História familiar de pectus foi relatada por 17 escolares (65,4 por cento), e 17 (65,4 por cento) relataram dor torácica, dispneia ou palpitações. CONCLUSÕES: A prevalência das deformidades pectus encontrada neste estudo (1,95 por cento) foi inferior àquela de trabalhos em outras regiões do país (3,6-4,9 por cento), porém, superior àquela relatada na literatura (média, 1 por cento).
