ABSTRACT
Background: Venous thromboembolism (VTE) is one of the most well-known and feared sequelae of orthopaedic surgery. VTE is relatively common after arthroplasty, prophylaxis has been prescribed. The frequency of postoperative thromboembolic events increased in the absence of primary prevention. Following operations, immobilisation of a lower limb that restricts calf muscle contraction has been shown to be a key risk factor for VTE. VTE is the most frequent source of readmission in orthopaedic patients who have undergone major procedures. It should be emphasized that the best mechanical method for preventing VTE is early walking. Medication for VTE prophylaxis is prescribed more often than mechanical prophylaxis. After major orthopaedic surgery, anticoagulant treatment is essential for reducing morbidity and death. Following hospital discharge, prophylactic drug therapy aims to reduce the morbidity and mortality episodes associated with DVT and PE occurrences. Aspirin use for prevention of VTE following THA and TKA has gained popularity, especially among orthopaedic surgeons due to a minimal risk of postoperative haemorrhage, it also reduces the incidence of recurrent DVTs. Conclusion: Due to its low cost and easy administration without the requirement for regular blood testing, aspirin thromboprophylaxis following knee surgery appears promising. Aspirin saved more QALYs and was cost-effective. Aspirin was demonstrated to have a higher VTE prophylaxis profile than other medications with a time-related association to early mobilisation, healthier patients and medication compliance.
ABSTRACT
Muitos pacientes que necessitam de intervenção odontológica, atualmente, são usuários de terapia medicamentosa antitrombótica. Essa condição se mostra prevalente, considerando que problemas cardiovasculares afetam grande parte da população. Objetivo: construir um protocolo clínico para o Serviço de Odontologia e Estomatologia do Hospital das Clínicas de Ribeirão Preto da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo, a partir de evidências científicas. Revisão de literatura: foi realizada uma pesquisa bibliográfica nas bases de dados eletrônicas Scientific Eletronic Library Online (SciELO) e Public MedLine (PubMed), nos idiomas português e inglês, do período entre 2013 e 2017. Após obtenção dos periódicos, foram selecionados os que se tratavam de estudos clínicos e seguiu-se com tradução, leitura e análise dos artigos. Com base nas evidências científicas, optou-se por construir o protocolo a partir da classe de medicamento utilizada pelos usuários de terapia antitrombótica (antiagregantes plaquetários, anticoagulantes orais e novos anticoagulantes orais) e orientações (pré, intra e pós-operatórias) para cada procedimento odontológico. Considerações finais: o protocolo clínico estabeleceu parâmetros para condutas clínicas e cirúrgicas em atendimento ambulatorial e hospitalar, possibilitando o cuidado integral aos usuários de terapia antitrombótica. Futuros estudos clínicos são necessários para validação e adequação para seu uso em diferentes serviços. (AU)
Several patients who require dental intervention are current users of antithrombotic drug therapy. This condition is prevalent, considering that cardiovascular problems affect a large portion of the population. Objective: this study aimed to construct a clinical protocol for the Service of Dentistry and Stomatology of the Clinics Hospital of Ribeirão Preto from the Medical School of Ribeirão Preto of the University of São Paulo, Brazil, based on scientific evidence. Literature review: a bibliographic review was performed in the Scientific Electronic Library Online (SciELO) and Public MedLine (PubMed) electronic databases, in the Portuguese and English languages, for the period of 2013 through 2017. After obtaining the journals, the clinical studies were selected, followed by the translation, reading, and analysis of the articles. Based on the scientific evidence, we decided to build the protocol from the class of medication of the users of antithrombotic therapy (antiplatelet agents, oral anticoagulants, and new oral anticoagulants), and guidelines (pre-, intra-, and postoperative) for each dental procedure. Final considerations: the clinical protocol established parameters for clinical and surgical procedures in outpatient and hospital care, allowing comprehensive care to users of antithrombotic therapy. Further clinical studies are required to validate and adequate the use of this therapy in different services. (AU)
