Piotr Czempik: Anti-Xa-Guided Enoxaparin Prophylaxis in Extreme Obesity
Piotr Czempik, Chair of Department of Anesthesiology and Intensive Care at Medical University of Silesia, shared on LinkedIn about recent article he and his colleague co-authored, published in Journal of Transfusion Medicine and Hemostasis, adding:
”How to provide safe and effective antithrombotic prophylaxis in extremely obese patients?
Happy to share our latest case report addressing this challenging critical care issue.
What the paper covers:
Patients >150–200 kg often fail to reach target anti‑Xa levels with standard low-molecular-weight heparin (LMWH) dosing.
In our 200‑kg ICU patient, we implemented a fully individualized strategy using:
- weight‑based enoxaparin dosing
- twice‑daily administration
- serial anti‑Xa monitoring
- additional ROTEM analysis for anticoagulation interpretation
- dynamic dose adjustment to maintain intermediate‑intensity antithrombotic prophylaxis
The result: effective VTE prevention with no bleeding events, demonstrating the value of personalized anticoagulation in this high‑risk population.
Key insight:
An initial enoxaparin dose of 0.3 mg/kg SC BID, followed by anti‑Xa–guided adjustment, may offer a rational and safer approach for ICU patients with extreme obesity.”
