Preparing for Surgery with VWD
For individuals with VWD, preparation for surgery involves raising VWF levels to ensure proper clotting. This is done by administering VWF concentrates intravenously before the procedure. The goal is to achieve a VWF activity level of about 100 IU/dL, checked in the recovery room to avoid delays.
Managing VWF Levels During Surgery
VWF levels are maintained above 50 IU/dL throughout the surgery using repeated infusions. The frequency of infusions, typically every 8 to 12 hours, is determined based on the patient's response and clinical picture. Continuous monitoring ensures any rapid clearance or recovery issues are promptly addressed.
Addressing Potential Complications
During surgery, complications like thrombosis may arise if factor VIII levels become excessively elevated. Careful monitoring helps prevent such risks by adjusting dosages. In some cases, continuous infusion of VWF may be necessary to manage inhibitors effectively.
FAQs
How are VWF levels managed during surgery?
Levels are maintained above 50 IU/dL with repeated infusions.
What is the target VWF activity level before surgery?
The target level is about 100 IU/dL.
Why is continuous monitoring important during surgery?
It helps manage rapid clearance and prevent complications.
Wrapping Up
Effective management of VWF levels is essential for safe surgical outcomes in VWD patients.
