Factors associated with changes in creatine phosphokinase (CPK) in trauma patients submitted to the "Red Wave", with evolution to rhabdomyolysis.

OBJECTIVE: to identify and analyze factors associated with plasma creatine phosphokinase (CPK) levels in trauma victims with progression to rhabdomyolysis. METHODS: we conducted a prospective, longitudinal study, with 50 patients submitted to the "Red Wave" protocol, with evolution to rhabdomyolysis after hospital admission. We studied the variables age, gender, trauma scores, mechanism and outcome, CPK at admission and final, intervals of days between laboratory evaluations, surgery and complications. We stratified CPK values in <500U/L, ≥500 - <1000 U/L, and ≥1000U/L, with calculation of the difference between the initial and final values. RESULTS: at admission, 83% of patients (n=39) had CPK≥1000U/L, with predominance of blunt trauma and thoracic injury (p<0.05), as well as orthopedic fracture, acute renal failure and gastrointestinal bleeding, CPK being lower in those without acute renal injury, with a trend towards statistical significance. There were no differences in final CPK stratification. Factors that were independently associated with the greater CPK variation were, positively, hospitalization time greater than one week and compartment syndrome, and negatively, acute renal injury. CONCLUSION: the CPK level of 1000U/L remains the lower limit, with importance for early intervention in worsening conditions such as digestive hemorrhage, acute renal injury and compartment syndrome, which implied greater absolute differences between initial and final CPK, in addition to blunt trauma, thoracic injury and orthopedic fracture.

RESUMO Objetivo: identificar e analisar fatores associados à variação dos níveis plasmáticos de creatina fosfoquinase (CPK) em vítimas de trauma com evolução à rabdomiólise. Métodos: estudo longitudinal prospectivo, com 50 pacientes que seguiram para o protocolo "Onda Vermelha", com evolução à rabdomiólise, após admissão hospitalar. Foram estudadas as variáveis: idade, sexo, escores, mecanismo e desfecho de trauma, CPK na admissão e final, intervalos de dias entre as avaliações laboratoriais, realização de cirurgia e complicações. Os valores da CPK foram estratificados em <500U/L; ≥500 - <1000 U/L; ≥1000U/L, com cálculo da diferença entre os valores inicial e final. Resultados: à admissão, 83% dos pacientes (n=39) apresentavam CPK≥1000U/L, com predomínio de trauma contuso e lesão torácica (p<0,05), além de fratura ortopédica, lesão renal aguda e hemorragia digestiva, sendo que a CPK era menor naqueles sem lesão renal aguda, com tendência à significância estatística. Não houve diferenças na estratificação por CPK final. Fatores que se revelaram independentemente associados à maior variação da CPK foram, positivamente, o tempo de internação superior a uma semana e síndrome compartimental, e negativamente, lesão renal aguda. Conclusão: como achado, nível de CPK de 1000U/L permanece como limite inferior, com importância à intervenção precoce em condições de agravamento do quadro, como hemorragia digestiva, lesão renal aguda e síndrome compartimental, que implicaram maiores diferenças absolutas entre CPK inicial e final, além do trauma contuso, lesão torácica e fratura ortopédica.

Evolução da qualidade das informações das declarações de óbito com menções de sífilis congênita nos óbitos perinatais no Brasil / Evolution of quality of information in death certificates mentioning congenital syphilis in perinatal deaths in Brazil

Resumo Objetivo avaliar a qualidade das informações das declarações de óbito (DO) com menções de sífilis congênita (SC) nos óbitos perinatais no Brasil (2001/2002 e 2012/2013). Métodos estudo transversal com dados do Sistema de Informações de Mortalidade de óbitos fetais e neonatais precoces. Foram calculadas taxas de mortalidade fetal, neonatal precoce e perinatal específicas por SC, percentual de incompletude por variáveis selecionadas, razões de causa básica e causa múltipla (CB/CM) e outros indicadores. Analisou-se causa básica original comparativamente à causa básica após investigação. Resultados em 2001/02 e 2012/13, ocorreram 330 e 933 óbitos perinatais, respectivamente, com menção de SC; a taxa de mortalidade perinatal passou de 4,2 a 12,8 por 100 mil nascimentos totais. A completude dos principais campos de preenchimento obrigatório melhorou, com CB/CM de 0,8 para SC, indicando registro adequado dessa causa com as causas múltiplas. A participação da SC como causa básica da morte aumentou pós-investigação, passando de 31,2% para 85,4% (óbitos fetais) e de 54,5% a 76,2% (neonatais precoces). Conclusão a taxa de mortalidade perinatal por SC aumentou, com melhora do preenchimento das DO. O uso das causas múltiplas de morte permitiu análise dos óbitos perinatais com menção de SC, o que é importante, dados os esforços na redução dessa doença.

Abstract Objective Evaluate the quality of information in death certificates (DC) mentioning congenital syphilis (CS) in perinatal deaths in Brazil (2001/02 and 2012/13). Methods Crossectional study with data from the Mortality Information System about fetal and early neonates. Fetal, early neonatal and perinatal mortality rates specific by CS, percentage of incompleteness by selected variables, underlying causes and multiple causes of death ratio (CB/CM), and other indicators were calculated. The original underlying cause was compared to the underlying cause after investigation. Results In 2001/02 and 2012/13, 330 and 933 perinatal deaths, respectively, with CS occurred; perinatal mortality rate increased from 4.2 to 12.8 per 100.000 total births. The completion of the main required fields has improved. The CB/CM ratio was 0.8 for CS, indicating adequate registration of this cause, with use of multiple causes. CS percentage as the underlying cause increased post-investigation, from 31.2% to 85.4% (fetal deaths) and from 54.5% to 76.2% (early neonates). Conclusion perinatal mortality rate due to CS increased over the study period. There was improvement in the completion of the DC. The use of multiple causes of death allowed the analysis of all perinatal deaths with CS mention, which is important given efforts in reducing CS.
