4、 procedures,warfarin should be stopped for 5 to 6 days prior to the procedure to allow gradual normalization of the international normalized ratio(INR).For urgent procedures,use of prothrombin complex concentrate is highly effective in rapidly reversing warfarin anticoagulant activity and has a dura

5、tion of action of 6 hours.The use of bridging heparin therapy is dependent on the risk of thrombosis.Discuss the risk of bleeding with the surgeon and anesthesiologist to determine optimal timing for resuming warfarin and bridging heparin therapy after surgery.ScopeKey RecommendationsRisksManagement

6、RisksThe management of warfarin therapy in patients undergoing surgery or other invasive procedures involves a fine balance between the risk of hemorrhage if the procedure was performed while on warfarin,and the risk of thrombosis if warfarin was discontinued.The thrombotic risk in the perioperative

7、 period depends on pre-existing conditions,the time since the last episode of thrombosis,and the thrombotic effect of surgery.The risk of hemorrhage in the perioperative period depends on the patients age,associated medical conditions,type of procedure,approach,site,type of incision and closure,and

8、the method of administration of anesthesia and analgesia.It is recommended that the anesthesiologist and the surgeon be consulted in determining the hemorrhagic riskRisksPreoperative management of warfarin therapy consists of timely discontinuation of warfarin and replacement(known as“bridging”)with

9、 therapeutic low molecular weight heparin(LMWH)or unfractionated heparin if the risk of thrombosis is considered to be sufficiently high.Almost all patients will achieve an international normalized ration(INR)of 70 years)will require a longer period of warfarin withdrawal before surgery.Patients wit

10、h a high risk of thromboembolism or stroke may benefit from bridging with heparin during the preoperative period,either as outpatients(LMWH subcutaneously)or inpatients(unfractionated heparin intravenously)by shortening the duration of subtherapeutic anticoagulation.RisksPostoperative management of

11、warfarin therapy consists of re-initiation of anticoagulation.Postoperative anticoagulation increases the rate of major bleeding.Typically,warfarin can resume the evening of or next day after the procedure because the anticoagulant activity is not established for several days.Restarting warfarin may

12、 be delayed in neurosurgical patients,those receiving epidural analgesia and in patients who are bleeding.For patients at high risk of thrombosis,LMWH by injection is given concurrently with warfarin and the overlap is maintained until a therapeutic INR has been reached.LMWH used postoperatively may

13、 allow earlier discharge of the patient compared with using unfractionated heparin.RisksIf urgent or emergent procedures are to be undertaken in 4-5 days and warfarin reversal is required,it may be satisfactory to give 1-2 mg of vitamin K orally in order to expedite the reversal process.When reversa

14、l of anticoagulation is required within 6 hours,intravenous vitamin K and prothrombin complex concentrate(PCC)(e.g.,Octaplex,Beriplex)is highly effective and is recommended over frozen plasma infusion.ScopeKey RecommendationsRisksManagementManagementManagementManagement Management of Perioperative A
