RESUMO
Objective The present study aimed to evaluate the results of the intraoperative topical use of a human fibrin sealant free of clot-stabilizing agents in total knee arthroplasties (TKAs), looking for differences between groups regarding blood loss, transfusion requirement, length of hospital stay, pain perception, range of motion (ROM), and incidence of complications. Methods We have analyzed prospectively an intervention group with 32 patients (Sealant) and a control group with 31 patients (Control) with symptomatic knee osteoarthritis who underwent TKA. Results The results were similar between the groups regarding visible blood loss in the drain in 24 hours (Control, 276.5 mL ± 46.24 versus Sealant, 365.9 mL ± 45.73), total blood loss in 24 hours (Control, 930 mL ± 78 versus Sealant, 890 mL ± 67) and in 60 hours after surgery (Control, 1,250 mL ± 120 versus Sealant, 1,190 mL ± 96), blood transfusion requirement (which occurred only in 1 control patient), length of hospital days stay (Control, 5.61 ± 0.50 versus Sealant, 4.81 ± 0.36), postoperative pain, and ROM. Sealant use was not related to wound healing complications, to infection, or to deep venous thrombosis. Conclusion We have concluded that the hemostatic agent composed of human fibrin was not effective in reducing bleeding volume and blood transfusion requirement, nor it interfered with hospital length of stay, pain perception, and ROM. Its use was not related to any complications.

Resumo Objetivo O objetivo do presente estudo foi avaliar os resultados do uso tópico intraoperatório do selante de fibrina humano livre de agentes estabilizadores de coágulo em pacientes com osteoartrite (OA) submetidos a artroplastia total de joelho (ATJ), buscando diferenças entre os grupos em relação à perda sanguínea, à necessidade transfusional, ao tempo de internação hospitalar, à percepção de dor, à amplitude de movimento e à incidência de complicações. Métodos Foram analisados prospectivamente um grupo de intervenção (Selante) com 32 pacientes e um grupo controle (Controle) com 31 pacientes, com OA sintomática dos joelhos, submetidos a ATJ. Resultados Os resultados foram semelhantes entre os grupos, em relação à perda sanguínea visível no dreno em 24 horas (Controle 276,5 mL ± 46,24 versus Selante 365,9mL ± 45,73), à perda sanguínea total em24 horas (Controle 930 mL ± 78 versus Selante 890 mL ± 67) e em 60 horas de pós-operatório (Controle 1.250 mL ± 120 versus Selante 1.190 mL ± 96), à necessidade de hemotransfusão (ocorreu em apenas 1 controle), ao tempo de dias na permanência hospitalar (Controle 5,61 ± 0,50 [n = 31] versus Selante 4,81 ± 0,36), dor pós-operatória e amplitude de movimento. O uso do agente selante de fibrina não se relacionou à ocorrência de complicações da cicatrização de ferida, de infecção ou de trombose venosa profunda. Conclusão Concluímos que o agente hemostático de fibrina humana não foi eficaz em reduzir o volume de sangramento e a necessidade de hemotransfusão ou em interferir no tempo de internação hospitalar, na percepção de dor e na amplitude de movimento. Seu uso não se relacionou a nenhuma complicação.
