Vitamin K to Manage Blood Thinning Before Surgery
Treatments studied
This study tests whether vitamin K can safely help manage warfarin (a blood thinner) before surgery. If you take warfarin at home and need an upcoming surgery, this trial may help you avoid hospitalization for blood-thinning adjustments.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have been taking warfarin for at least 3 months
- You use home INR testing equipment (a device to check your blood thickness at home)
- You have a scheduled surgical procedure that requires lowering your blood thickness significantly
- Your most recent INR test (within 7–10 days before surgery) was 4 or lower
- You are fluent in English
- You do not have a history of blood clots in the past 3 months

This trial compares two ways to prevent blood clots after open heart surgery: a “direct oral” blood thinner pill versus warfarin (a vitamin K antagonist). It may help find the safest and most effective option for people who develop atrial fibrillation after surgery.
This study looks at whether a virtual visit can safely manage your blood thinners around the time of a planned surgery. You would stop your medication before the procedure and restart it after, but all instructions and check-ins happen remotely (phone or video).

This study looks at how to safely manage your blood thinner (DOAC) around the time of a planned, high-bleed-risk surgery or procedure involving a spinal needle. The goal is to find the best way to stop and restart your medication to prevent bleeding and clotting problems.
This study looks at whether a structured (protocol-based) care plan before and around surgery improves outcomes for people taking blood-thinning medicines. It may help teams plan safer timing and monitoring to reduce complications around the operation.
This trial compares two ways of managing blood thinners around heart device surgery to find the safest and most effective approach. If you are eligible, you would be randomly assigned to one of the two strategies.
