ABSTRACT
Abstract Objective To collect data on the role played by tranexamic acid in the prevention and management of blood loss in patients undergoing total hip arthroplasty and total knee arthroplasty. Methods In the present prospective, comparative study, 30 patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA) were randomly allocated into 1 of 2 groups with 15 patients each. Tranexamic acid was administered by intravenous and topical routes in the study group, but it was not administered in the control group. Preoperative blood parameters, intraoperative and postoperative blood loss, and need for blood transfusion were noted. Statistical analysis was performed using the chisquared test and the independent t-test. Results The study group had statistically significant higher postoperative hemoglobin values (p = 0.03), less difference between pre and postoperative hemoglobin value (p = 0.046), less difference between pre and postoperative packed-cell volume (p = 0.06), less intraoperative measured blood loss (p = 0.015), and less volume of blood collected in the drain (p = 0.0291) compared with the control group. There was also reduced frequency of blood transfusions in the study group (p = 0.0008). Conclusion Tranexamic acid is associated with reduced intra and postoperative blood loss and reduced frequency of blood transfusions in patients undergoing THA/TKA.
RESUMO
Resumo Objetivo Coletar dados sobre o papel desempenhado pelo ácido tranexâmico na prevenção e gerenciamento da perda de sangue em pacientes submetidos à artroplastia total do quadril (ATQ) e à artroplastia total do joelho (ATJ). Métodos Neste estudo prospectivo e comparativo, 30 pacientes submetidos à ATQ ou à ATJ foram alocados aleatoriamente em 1 de 2 grupos com 15 pacientes. O ácido tranexâmico foi administrado por rotas intravenosas e tópicas no grupo de intervenção, mas não foi administrado no grupo controle. Foram observados parâmetros sanguíneos pré-operatórios, perda de sangue intrae pós-operatória e necessidade de transfusão de sangue. A análise estatística foi realizada utilizando-se teste do qui-quadrado e o teste-t independente. Resultados O grupo de intervenção apresentou hemoglobina mais elevada no pósoperatório de forma estatisticamente significante (p = 0,03), menor diferença entre concentração de hemoglobina pré- e pós-operatória (p = 0,046), menor diferença entre volume de células embaladas pré- e pós-operatório (p = 0,06), menor perda de sangue intraoperatória medida (p = 0,015) e menor volume de sangue coletado na drenagem (p = 0,0291) em comparação com o grupo controle. Também houve redução da frequência de transfusões de sangue no grupo de intervenção (p = 0,0008). Conclusão O ácido tranexâmico está associado à redução da perda sanguínea intraoperatória e pós-operatória e à redução da frequência de transfusões de sangue em pacientes submetidos à ATQ/ATJ.
