Anticoagulation for Mechanical valves
Anticoagulation for Surgical Procedures in patients with Mechanical valves
For high risk non-cardiac surgeries in patients with Mechanical valves Warfarin is stopped prior to surgery with goal to achieve INR———— at the time of operation
A. < 1
B. < 0.5
C. < 1.0
D. < 1.5
|Anticoagulation Management for Surgical Procedures in patients with Mechanical valves||INR Goal during operation|
|1||High risk surgeries||INR < 1.5|
|2||Low risk surgeries||INR 1.7 to 2.3|
When anticoagulation is restarted after non-cardiac surgery in patients with mechanical valves?
- Heparin is started after 24 hrs of surgery following confirmation of hemostasis
- warfarin is started at the same time.
- Heparin is continued until INR is therapeutic.
- Then Heparin is stopped and warfarin is continued
