When is bridging therapy necessary?
The intent of bridge anticoagulant therapy is to minimize both the risk of thromboembolic events and the risk of bleeding during the peri-operative period. Bridging anticoagulant therapy is appropriate for some but not all patients undergoing medical procedures.
What is bridging anticoagulation?
‘Bridging” is a term that refers to the use of short-acting anticoagulants (heparin or LMWH) for a period of time during interruption of warfarin therapy when the INR is not within a therapeutic range.
When do you stop anticoagulants before surgery?
In general, the anticoagulant must be discontinued if the surgical bleeding risk is high. Those at very high or high thromboembolic risk should limit the period without anticoagulation to the shortest possible interval; in some cases, this involves the use of a bridging agent.
How long do you have to stop heparin before surgery?
During the preoperative period: Discontinue warfarin five days before surgery. Three days before surgery, start subcutaneous LMWH or unfractionated heparin (UFH), depending on the renal function of the patient at therapeutic doses.
When do you start anticoagulation after spinal surgery?
Administering anticoagulation therapy from 1 day before to 3 days after surgery is safe for patients at high risk for VTE.
What does INR need to be for surgery?
A level of INR of 1.5 or below was considered suitable for surgery. A final PT and INR level was obtained for every patient on the morning of surgery. If the patient still had an increased INR (1.8 or above) after 3 days, vitamin K (oral preparation of 1–2.5 mg) was given.
How long after stopping blood thinners can you have surgery?
Currently, atrial fibrillation patients are typically told to halt their warfarin for five days before and after they undergo an elective procedure, because it can cause dangerous bleeding and slow healing.
