Jorge,Pedro Baches; Sprey,Jan Willem Cerf; Runco,Guilherme Morgado; Lima,Marcos Vaz de; Severino,Nilson Roberto; Santili,ClaudioAbstract Objective To determine whether type-II collagen degradation is determined by the type of sport. Carboxy-terminal telepoptide of type-II collagen (CTX-II), a serum biomarker of collagen degradation, was measured in athletes who play different sports, and was compared with matched controls. Methods The sample size consisted of 70 female participants aged between 18 and 25 years, 15 of whom were members o...
Comparative study of topical vs. intravenous tranexamic acid regarding blood lo...
Zekcer,Ari; Priori,Ricardo Del; Tieppo,Clauber; Silva,Ricardo Soares da; Severino,Nilson RobertoABSTRACT Objective: To compare topical vs. intravenous tranexamic acid (TA) in total knee arthroplasty regarding blood loss and transfusion., Methods: Ninety patients were randomized to receive TA intravenously (20 mg/kg in 100 mL of saline; group IV), topically (1.5 g in 50 mL of saline, sprayed over the operated site, before release of the tourniquet; topical group), or intravenous saline (100 mL with anesthe...
Topical vs. intravenous administration of tranexamic acid in knee arthroplasty ...
Zekcer,Ari; Del Priori,Ricardo; Tieppo,Clauber; Silva,Ricardo Soares da; Severino,Nilson RobertoAbstract Background Tranexamic acid (TXA) is widely used in orthopedic surgery to reduce perioperative bleeding. Since TXA inhibits fibrinolysis, there is concern that it may increase the risk of thromboembolic events. Objectives To verify the prevalence of deep venous thrombosis (DVT) in patients receiving TXA during total knee arthroplasty and to compare topical with intravenous administration of the drug. Me...
