RESUMO
Foram estudados restrospectivamente os coagulogramas de 65 pacientes submetidos a revisão de hemostasia no pós-operatório imediato de cirurgia cardíaca. Os coagulogramas foram considerados compatíveis ou não com distúrbio da coagulação sangüínea, por hematologista que desconhecia o achado cirúrgico. Dentre 51 pacientes cujos valores do coagulograma foram considerados normais, 46 (90,2%) apresentavam sangramento ativo localizado, passível de correção cirúrgica. Os 5 (9,8%) demais pacientes apresentavam sangramento difuso. Dentre os 14 pacientes restantes, cujo coagulograma encontrava-se alterado, 8 (57,2%) apresentavam sangramento difuso e 6 (42,8%), localizado. Os autores concluem que, na persistência de sangramento excessivo pós-operatório e coagulograma normal, a revisão de hemostasia deverá ser prontamente indicada. Entretanto, se houver alteração do coagulograma, dever-se-à empregar, inicialmente, o tratamento clínico, desde que o ritmo do sangramento o permita. Caso o sangramento persista, mesmo com melhora do coagulograma, deverá ser pesquisada a presença de coágulos retidos no mediastino. Se positiva, deve-se programar nova toracotomia, visando à remoção de coágulos do mediastino.ABSTRACT
Blood coagulation of 65 patients that needed reoperation to control excessive bleeding after cardiopulmonary bypass surgery was evaluated by hematologist that didn't know the reoperation findings. Forty-six (90.2%) of 51 patients with normal tests before the reintervention had localizated bleeding, and five (9.8%) had difuse hemorrhage. From 14 patients with abnormal coagulation tests, eight (57.2%) had difuse bleeding and six (42.8%) had a localizated bleeding. The authors concluded that with normal coagulation tests and excessive bleeding after cardiopulmonary bypass surgery a new reoperation is indicated. Otherwise, patients with abnormal coagulation tests can receive initial clinical treatment.REFERÊNCIAS
