Thromboelastography (TEG) and Clopidogrel Withdrawal Time in Elderly Patients With Hip Fracture

In the elderly patients with hip fracture, some often take antiplatelet drugs such as clopidogrel due to the ischemic cardiovascular or cerebrovascular diseases. In traditional practice, these patients often need to stop medication for 5-7 days before surgery. But on the other hand, delayed surgery will lead to a significant increase in fracture related complications. Therefore, the appropriate time for drug withdrawal is particularly important in this population. Thromboelastography is a monitoring method that can accurately judge the anticoagulation status of patients. We hope to use thromboelastography to guide the time of drug withdrawal, shorten the time of drug withdrawal as much as possible, and reduce the incidence of fracture related complications without increasing the risk of massive hemorrhage.
