Despite pharmacological thromboprophylaxis, usually LMWHs, the incidence of VTE is relatively high in critically ill patients
The aim of this systematic review was to evaluate the reasons to monitor plasma anti-FXa levels
After screening total 18 eligible studies including 1644 patients, were selected
There was a wide variation in the median peak anti-FXa levels (< 0.1-0.34 IU/ml)
No conclusions can be drawn on targeted anti-FXa levels in critically ill patients when using LMWH thromboprophylaxis
