This study compares two oral medications (tranexamic acid and aminocaproic acid) as hemostatic agent administered in patients undergoing primary total hip replacement
Full description
With the aging population, the incidence of joint osteoarthritis is rising. Total hip arthroplasty (THA) is one of the most common surgeries used for the treatment of end-stage degenerative hip disease, which is almost always accompanied by joint pain, deformity and motor dysfunction.
Few articles have compared TXA and ε-ACA in joint arthroplasties. Whether ε-ACA has comparable hemostatic effects compared with TXA is unknown. A recent systematic review compared the effectiveness of TXA versus ε-ACA administered intravenously as a hemostatic agent in patients who had undergone a TKA and THR, and the results showed that the total blood loss was greater in the ε-ACA groups, but no significant differences between the two groups regarding transfusion rates were identified (Liu et al., 2018).
Regarding oral administration, two clinical trials compared the use of oral TXA versus intravenous and topical in patients who had undergone THA, reaching the conclusion that if efficiency, safety, and cost are considered the main crucial parameters during the evaluation of TXA administration methods, oral TXA stands as an efficacious, safe, and low-cost method to reduce blood loss after THA compared with the IV and topical forms. Additionally, considering the ease of drug administration in the tablet form, oral TXA appears to represent a superior mode of administration than IV and topical TXA (Kayupov et al., 2017; Luo et al., 2018).
The investigator's work team previously published a randomized controlled clinical trial in which it prospectively compared blood loss, transfusion rate and complications similar to this study but in total primary knee replacement, finding no differences with respect to any of the parameters studied except for the adverse effects, which were greater for the group that received tranexamic acid, this study was the first to compare the oral administration of these two medications in the field of orthopedics (Morales-Avalos et al., 2019) and the present protocol wants to do it now in the total primary hip replacement which is well known to be associated with greater blood loss than total knee replacement.
HYPOTHESIS: There are no significant differences in blood loss (total blood loss, external blood loss, hidden blood loss, intraoperative blood loss and drainage output), transfusion index, complications and hemoglobin/hematocrit levels in patients undergoing total hip prostheses treated with tranexamic acid or aminocaproic acid orally.
General objectives To compare the effect of oral aminocaproic acid as a hemostatic agent against oral tranexamic acid administered preoperatively and postoperatively in patients undergoing elective surgery of total hip replacement.
