Abstract in Portuguese
Introdução. O transporte é um procedimento crítico na manutenção da cadeia do frio do sangue. Falhas neste procedimento podem comprometer a sua qualidade e a segurança transfusional. Objetivo. Avaliar as não conformidades (NC) do Hemocentro de Ribeirão Preto relacionadas ao transporte de concentrado de hemácias (CH). Analisar caixas térmicas e gelos recicláveis submetidos à temperatura de 20°C e 30°C e propor melhorias neste processo. Métodologia. Estudo retrospectivo de NC relacionadas ao transporte de CH no software do sistema da qualidade do Hemocentro de Ribeirão Preto e pesquisa experimental realizada com três caixas diferentes em combinação com três gelos recicláveis distintos, simulando uma situação de transporte, nas temperaturas externas de 20°C e 30°C. Realizou-se uma estatística descritiva com os dados. Utilizou-se a metodologia de análise de variância (ANOVA), com o auxílio do software SAS® 9, utilizando a PROC GLM. Para as comparações foram utilizados contrastes ortogonais baseados na distribuição t. Resultados. Os resultados mostraram diferenças significativas no desempenho entre as caixas e entre os gelos recicláveis. No entanto, as maiores diferenças ocorreram entre as temperaturas externas de 20°C e 30°C, indicando a interferência da temperatura externa na temperatura do conteúdo interno. Outra diferença encontrada foi entre pontos de aferição das temperaturas, dentro da mesma caixa, indicando que a distribuição do ar, no interior da caixa não é homogênea. Conclusão. São vários os interferentes existentes durante o transporte de CH, que podem comprometer a qualidade do sangue. O transporte deve ser validado, padronizando o maior número de variáveis possíveis, para minimizar as adversidades que ocorrem durante o procedimento

Abstract in English
Introduction. The transport is a critical procedure in the maintenance of the blood cold chain. Failures in this procedure can compromise the blood quality and transfusion safety. Purpose: Evaluate the non-conformances (NC) of Hemocentro de Ribeirão Preto related to the Red Blood Cell (RBC) transport. Verify coolers, recycle ice at a temperature of 20°C and 30°C and propose improvements in this process. Methodology: Retrospective study of NC related to RBC transport in Hemocentro de Ribeirão Preto quality system software. Experimental research performed with three different insulated boxes combined with three different ice packs, simulating a situation of transport in the external temperatures of 20°C and 30°C. It was made a descriptive statistic of the data. The methodology of analysis of variance was used, through the software SAS® 9, using a PROC GLM. To do the comparisons orthogonal contrasts based on t distribution were used. Results: The results shown significant differences between insulated box and ice packs. However, the larger differences occurred between the temperatures of 20°C and 30°C, indicating that the external temperature interfere in the temperature inside the box. Another difference found was between points of temperature, inside the same insulated box, indicating that the air distribution inside the insulated box is not homogeneous. Conclusion. During RBC transport, many interfering exist that can compromise the blood quality. The transport must be validated, standardizing the largest number of details that is possible, to minimize adversity that occur during the procedure
