The aim of the study was to determine the long-term survival in patients undergoing total hip arthroplasty in relation to type of perioperatively administered thromboprophylaxis. Patients from seven randomized controlled trials of the effect of thromboprophylaxis on development of early thromboembolic complications after total hip arthroplasty were included in a follow-up analysis with death as the end-point. There was no difference in survival between groups receiving active thromboprophylaxis, but there was a general trend towards a better survival in the 3 placebo groups compared with low molecular weight heparin (LMWH), (RR: 1.53; C.I.: 1.04-2.25). There was a significant excess of cardiovascular deaths in the LMWH groups (RR: 2.48; CI: 1.45-4.24). Long-term prospective studies should be performed to assess the long-term effect of various thromboprophylactic regimens on morbidity and mortality after total hip arthoplasty.

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Venous Thrombosis IV: Nursing Management

Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...
