Published: Oct 24, 2023
Bridging anticoagulation involves using short-acting blood thinners before surgery in patients who normally take long-acting ones. But is this extra step always necessary?

What Is Bridging?
Bridging uses injectable blood thinners like heparin to prevent blood clots when a patient stops their usual oral medication before surgery. It's like a temporary stand-in to keep blood from clotting. The goal is to minimize time without protection from blood clots.
Who Needs Bridging?
Most patients don't need bridging therapy. It's mainly used for high-risk cases, such as those with mechanical heart valves or very recent blood clots or strokes. Your doctor will assess your individual risk factors to decide if bridging is necessary.

Risks vs. Benefits
While bridging can prevent blood clots in high-risk patients, it also increases bleeding risk during surgery. For most patients, the risks outweigh the benefits. Studies show bridging doesn't reduce clot risk for most people but does raise bleeding risk.
Frequently Asked Questions

Key Takeaways
Bridging therapy is necessary for some high-risk patients, but most can safely stop blood thinners briefly without it.
