ABSTRACT

Objective:

to determine the microbiological characteristics of the red blood cells obtained with the cell saver in heart surgery patients on an extra-body circuit.

Method:

a cross-sectional and descriptive study conducted with 358 patients scheduled for heart surgery where the saver was used. Sociodemographic variables were collected, as well as from the saver and of the microbial identification in the re-infusion bag proceeding from the cell saver. Informed consent performed.

Results:

of the 170 GRAM+ bacteria isolations, the most frequent species were Staphylococcus epidermidis in 69% (n=138) of the cases and Streptococcus sanguinis with a report of 10% (n=20). Significant differences were found in the Staphylococcus epidermidis strain in patients with a Body Mass Index ≥25 (p=0.002) submitted to valve surgery (p=0.001). Vancomycin was the antimicrobial which resisted the Staphylococcus epidermidis strain with a minimum inhibitory concentration of >16 µg/ml.

Conclusion:

the microbiological characteristics of the red blood cells obtained after processing autologic blood recovered with the cell saver during heart surgery are of GRAM+ bacterial origin, the most isolated species being Staphylococcus epidermidis. Consequently, in order to reduce the presence of these GRAM+ cocci, an antibiotic should be added to the cell saver reservoir, according to a previously established protocol.
RESUMO

Objetivo:

determinar as características microbiológicas dos glóbulos vermelhos obtidos com o "cell saver" em pacientes submetidos à cirurgia cardíaca em circuito extracorpóreo.

Método:

estudo descritivo transversal com 358 pacientes de cirurgia cardíaca em que o "cell saver" foi utilizado. Foram coletadas variáveis sociodemográficas e identificação microbiana da bolsa de reinfusão do "cell saver". Foi confirmado o Termo de Consentimento.

Resultados:

das 170 baterias isoladas GRAM+, as mais frequentes foram Staphylococcus epidermidis em 69% (n=138) dos casos e Streptococcus sanguinis com um registro de 10% (n=20). Diferenças significativas foram encontradas na cepa Staphylococcus epidermidis em pacientes com índice de massa corporal ≥25 (p=0,002) submetidos a cirurgia valvular (p=0,001). A vancomicina foi o antimicrobiano resistente à cepa Staphylococcus epidermidis com uma concentração inibitória mínima >16 µg/ml.

Conclusão:

as características microbiológicas dos glóbulos vermelhos obtidas após o processamento do sangue autólogo recuperado com o "cell saver" em cirurgia cardíaca são de origem bacteriana GRAM+, sendo a espécie mais isolada o Staphylococcus epidermidis. Portanto, para reduzir a presença desses cocos GRAM+, um antibiótico deve ser adicionado ao "cell saver", de acordo com um protocolo previamente estabelecido.
RESUMEN

Objetivo:

determinar las características microbiológicas de los glóbulos rojos obtenidos con el "cell saver" en el paciente de cirugía cardíaca bajo un circuito extracorpóreo.

Método:

estudio descriptivo transversal con 358 pacientes programados para cirugía cardíaca donde se utilizó el "cell saver". Se recogieron variables sociodemográficas e identificación microbiana de la bolsa de reinfusión procedente del "cell saver". Consentimiento informado realizado.

Resultados:

de 170 aislamientos de bacterias GRAM+, las especies más frecuentes fueron el Staphylococcus epidermidis en el 69% (n=138) de los casos y el Streptococcus sanguinis con un reporte del 10% (n=20). Se encontraron diferencias significativas en la cepa Staphylococcus epidermidis en pacientes con índice de masa corporal ≥25 (p=0,002) sometidos a cirugía valvular (p=0,001). La vancomicina fue el antimicrobiano resistente a la cepa Staphylococcus epidermidis con una concentración mínima inhibitoria >16 ug/ml.

Conclusión:

las características microbiológicas de los glóbulos rojos obtenidos tras el procesamiento de sangre autóloga recuperada con el "cell saver" en cirugía cardíaca son de origen bacteriano GRAM+ siendo la especie más aislada el Staphylococcus epidermidis. Por ello, con el fin de reducir la presencia de estos cocos GRAM+ se debería añadir un antibiótico en el reservorio del "cell saver", según un protocolo previamente establecido.
