This study will be a single-center, prospective, randomized controlled trial with an estimated sample size of 64 patients. Eligible patients will be randomly assigned in a 1:1 ratio to receive TTM for either 24 hours or 72 hours. The primary outcome measure will be the changes in thrombin function indices at various time points during TTM treatment in both groups. The secondary endpoints of the study include additional coagulation function indicators, the incidence of bleeding-related events between the two groups, the amount of blood products used, the incidence of thrombotic events, and the CPC scores at 28 days and 6 months for both groups.
