    Out of curiosity, how many of are at EDs where LMWH is routinely given instead of UFH IN THE ED for ACS? And if you do, presumably your hospital's cardiology interventionalists are on board. Do the admitting service use Anti Xa Assays (over ACT)? And, how long is the turn-around for the Assay? Anyone has assays that are batched and take only a few hours?

    Thanks for the input.

    i'm not in the ED, but at our hospital, bariatric surgery patients are routinely prophylaxed with LMWH and we check activated factor X assays to determine level since kinetics / biodistribution is less predictable in the morbidly obese. the turn around time is 3-4 hours. some super-obese pts receive both lovenox and an IVC filter peri-operatively.
