Objective:To explore the anticoagulant strategies during perioperative period for the patients with long-term anticoagu-lation therapy to show the important role of clinical pharmacist in drug treatment. Methods:The anticoagulant regimen during the peri-operative period participated by clinical pharmacists for one patient with long-term use of warfarin was reviewed, and combined with the related literatures, the drug choice, the administration time, dosage and treatment course were analyzed. Results: The clinical phar-macists could optimize the anticoagulant regimen by using the pharmacokinetic knowledge to decrease the risk of hemorrhage and embol-ism to the largest extent. Conclusion:During the perioperative period, warfarin should be withdrawn at least 5 days before the opera-tion, and the international normalize ratio ( INR) should be monitored. After the operation and no further bleeding, low molecular weight heparin combined with warfarin can be used in 12h, and INR should be monitored. Low molecular weight heparin can be with-drawn till the standard is reached. If the patient undergoes operation for many times, low molecular weight heparin is suggested to be used for anticoagulation during the whole operation period.
