Associação do estado nutricional e os desfechos clínicos em cirurgia cardíaca pediátrica / Relación del estado nutricional y los resultados clínicos en cirugía cardíaca pediátrica / Association of nutritional status and clinical outcomes in pediatric cardiac surgery

Resumo Objetivo Verificar a associação do fator pessoal biológico estado nutricional, das crianças submetidas à cirurgia cardíaca, com os seguintes comportamentos: mortalidade/alta hospitalar, tempo de internação na Unidade de Terapia Intensiva (UTI) e tempo de ventilação mecânica (VM). Métodos Estudo transversal, retrospectivo realizado com 786 prontuários de crianças menores de cinco anos, submetidas à cirurgia cardíaca. O modelo de Nola J. Pender foi usado para analisar os dados. Aplicou-se o teste Qui-Quadrado de Pearson para verificar associação entre o fator pessoal biológico e o comportamento mortalidade/alta hospitalar. O teste Kruskal-Wallis foi utilizado para verificar a diferença entre medianas do fator pessoal biológico e os comportamentos tempo de VM e de UTI. Resultados A associação entre os fatores pessoais biológicos (pobre estado nutricional, desnutrição aguda e desnutrição crônica) com o comportamento mortalidade foi de OR 2,18 (1,42 - 3,34), p=0,003, OR 0,75 (0,46 - 1,2), p=0,24 e OR 2,7 (1,77 - 4,12), p<0,0001, respectivamente. A mediana de tempo em dias de uso de VM e tempo em dias de UTI foi, respectivamente de 3 (p<0,0001) e 8 (p<0,0001) para o pobre estado nutricional, 2 (p=0,041) e 6,5 (p=0,006) para a desnutrição aguda, 3 (p<0,0001) e 8 (p<0,0001) para a desnutrição crônica. Conclusão Os fatores pessoais biológicos que tiveram associação significativa com o comportamento mortalidade foram o pobre estado nutricional e desnutrição aguda. Foi verificado que as crianças com déficits nutricionais analisados tiveram uma superior mediana de tempo de VM e tempo de UTI quando comparadas com as crianças sem déficits nutricionais.

Resumen Objetivo Verificar la relación del factor personal biológico estado nutricional de niños sometidos a cirugía cardíaca, con los siguientes comportamientos: mortalidad/alta hospitalaria, tiempo de internación en Unidad de Cuidados Intensivos (UCI) y tiempo de ventilación mecánica (VM). Métodos Estudio transversal, retrospectivo realizado con 786 historias clínicas de niños menores de cinco años sometidos a cirugía cardíaca. Para analizar los datos se utilizó el modelo de Nola J. Pender. Se aplicó la prueba χ2 de Pearson para verificar la relación entre el factor personal biológico y el comportamiento mortalidad/alta hospitalaria. La prueba de Kruskal-Wallis fue utilizada para verificar la diferencia entre medianas del factor personal biológico y los comportamientos tiempo de VM y de UCI. Resultados La relación entre los factores personales biológicos (mal estado nutricional, desnutrición aguda y desnutrición crónica) y el comportamiento mortalidad fue de OR 2,18 (1,42 - 3,34), p=0,003, OR 0,75 (0,46 - 1,2), p=0,24 y OR 2,7 (1,77 - 4,12), p<0,0001, respectivamente. La mediana del tiempo en días de uso de VM y tiempo en días de UCI fue de 3 (p<0,0001) y 8 (p<0,0001) respectivamente para el mal estado nutricional, 2 (p=0,041) y 6,5 (p=0,006) para la desnutrición aguda, 3 (p<0,0001) y 8 (p<0,0001) para la desnutrición crónica. Conclusión Los factores personales biológicos que tuvieron relación significativa con el comportamiento mortalidad fueron el mal estado nutricional y la desnutrición aguda. Se verificó que los niños con deficiencias nutricionales estudiados tuvieron una mediana mayor de tiempo de VM y tiempo de UCI en comparación con niños sin deficiencias nutricionales.

Abstract Objective To find the association of the biological personal factor 'nutritional status' of children undergoing cardiac surgery with the following behaviors: mortality/hospital discharge, length of stay in the Intensive Care Unit (ICU) and time in mechanical ventilation (MV). Methods Cross-sectional, retrospective study of 786 medical records of children under five years of age who underwent cardiac surgery. Nola J. Pender's model was used for data analysis. The Pearson's Chi-Square test was applied to find the association between the biological personal factor and the mortality/hospital discharge behavior. The Kruskal-Wallis test was used to assess the difference between medians of the biological personal factor and the behaviors of time in MV and ICU length of stay. Results The association between personal biological factors (poor nutritional status, acute malnutrition and chronic malnutrition) with mortality behavior was OR 2.18 (1.42 - 3.34), p=0.003, OR 0.75 (0.46 - 1.2), p=0.24 and OR 2.7 (1.77 - 4.12), p<0.0001, respectively. The median time in days of MV use and ICU length of stay in days was, respectively, 3 (p<0.0001) and 8 (p<0.0001) for poor nutritional status, two (p=0.041) and 6.5 (p=0.006) for acute malnutrition, 3 (p<0.0001) and 8 (p<0.0001) for chronic malnutrition. Conclusion The personal biological factors with a significant association with mortality behavior were poor nutritional status and acute malnutrition. Children with analyzed nutritional deficits had a higher median time of MV and time of ICU compared with children without nutritional deficits.

Analysis of surgical mortality for congenital heart defects using rachs-1 risk score in a brazilian single center

ABSTRACT Introduction: Risk Adjustment for Congenital Heart Surgery 1 (RACHS-1) score is a simple model that can be easily applied and has been widely used for mortality comparison among pediatric cardiovascular services. It is based on the categorization of several surgical palliative or corrective procedures, which have similar mortality in the treatment of congenital heart disease. Objective: To analyze the in-hospital mortality in pediatric patients (<18 years) submitted to cardiac surgery for congenital heart disease based on RACHS-1 score, during a 12-year period. Methods: A retrospective date analysis was performed from January 2003 to December 2014. The survey was divided in two periods of six years long each, to check for any improvement in the results. We evaluated the numbers of procedures performed, complexity of surgery and hospital mortality. Results: Three thousand and two hundred and one surgeries were performed. Of these, 3071 were able to be classified according to the score RACHS-1. Among the patients, 51.7% were male and 47.5% were younger than one year of age. The most common RACHS-1 category was 3 (35.5%). The mortality was 1.8%, 5.5%, 14.9%, 32.5% and 68.6% for category 1, 2, 3, 4 and 6, respectively. There was a significant increase in the number of surgeries (48%) and a significant reduction in the mortality in the last period analysed (13.3% in period I and 10.4% in period II; P=0.014). Conclusion: RACHS-1 score was a useful score for mortality risk in our service, although we are aware that other factors have an impact on the total mortality.
