ABSTRACT

Objetivo:

Avaliar se o uso de recuperadores de hemácias está indicado nos pacientes submetidos à cirurgia cardiovascular com o uso de circulação extracorpórea.

Métodos:

Foram estudados 77 pacientes submetidos a cirurgias cardíacas com uso de recuperadores de hemácias e circulação extracorpórea de novembro de 2010 a junho de 2012. A amostra foi subdividida em três grupos, conforme o tempo de circulação extracorpórea. No grupo A ,o tempo de circulação extracorpórea foi menor que 45, no grupo B, de 45 a 90 e, no grupo C, maior que 90 minutos. Analisou-se o volume recuperado e infundido de hemácias, a hemoglobina de pré, trans e pós-operatório, número de unidades de concentrado de hemácias transfundidas, volume globular e hemoglobina do sangue infundido.

Resultados:

A idade média, dos pacientes, foi de 60,44±12,09 anos, sendo 71,43% do sexo masculino. O grupo A é formado por 5,19%, o B por 81,82% e o C por 12,99% dos pacientes. O volume recuperado e infundido foi, respectivamente, de 1.360,50±511,37 ml e 339,75±87,71 ml no grupo A, 1.436,63±516,06 ml e 518,83±183,0 ml no B e 2.137,00±925,04 ml e 526,20±227,15 ml no C. Em relação às transfusões de concentrado de hemácias, no grupo A foram transfundidas 1,00±2,00 concentrado de hemácias, no B 1,27±1,85 concentrado de hemácias e no C 2,56±2,01 concentrado de hemácias. O sangue infundido tinha um volume globular de 50,97±12,06% e hemoglobina de 19,57±8,35 g/dl.

Conclusão:

O recuperadores de hemácias podem ser usados em pacientes submetidos à cirurgia cardiovascular com circulação extracorpórea, mas somente em cirurgias com tempo de circulação extracorpórea acima de 45 minutos o reaproveitamento de sangue ...
RESUMO

Objective:

To show if blood salvage is indicated in all patients submitted to cardiovascular surgery with cardiopulmonary bypass.

Methods:

We studied 77 consecutive patients submitted to cardiac surgery with use of blood salvage and cardiopulmonary bypass from November 2010 to June 2012. The sample was divided in three groups, depending on the time of cardiopulmonary bypass. In group A, the time of cardiopulmonary bypass was smaller than 45, in group B from 45 to 90 and in group C greater than 90 minutes. We analyzed the volume of red cells recovered and infused, the pre, intra and post-operative hemoglobin, the number of packed red cells units which were transfused and hematocrit and hemoglobin blood infused.

Results:

The average group age was 60.44±12.09 years old, of whom 71.43% were males. The group A was formed by 5.19% of the patients, B by 81.82% and C by 12.99%. The volume of erythrocytes recovered and infused was respectively 1,360.50±511.37 ml and 339.75±87.71 ml in group A, 1,436.63±516.06 ml and 518.83±183.0 ml in B and 2,137.00±925.04 ml and 526.20±227.15 ml in C. About packed red cells transfusions, in group A 1,00±2,00 packed red cells were transfused, in B 1.27±1.85 packed red cells and in C 2.56±2.01 packed red cells. The infused blood had a hematocrit of 50.97±12.06% and hemoglobin of 19.57±8.35 g/dl.

Conclusion:

That blood salvage can be used in patients submitted to cardiovascular surgery with cardiopulmonary bypass. However, it is only cost-effective in surgeries in which the time of cardiopulmonary bypass is greater than 45 minutes. .
