Description

VTE prophylaxis is more than just some squeezy leg socks and a one-size fits all dose of enoxaparin!  Ever wonder how VTE prophylaxis is similar to constipation?  Have you or a loved one been hurt by a hospital administrator telling you that VTE is a never event?  Come with us, and our special guest Dr. Bryan Cotton, on this journey to the frontier of research attempting to debunk this myth and improve patient care by reducing VTE rates in trauma patients.

Learning Objectives:

- Describe the rationale for the addition of aspirin to chemoprophylactic regimens for VTE

-  Identify appropriate screening systems for trauma patients at high risk for VTE

-  Describe the rationale for monitoring anti factor Xa levels in the trauma population receiving VTE chemoprophylaxis

- List the major conclusions of the two studies discussed regarding the addition of aspirin to VTE chemoprophylaxis regimens in trauma patients, and the change in antithrombin activity levels over time in relation to enoxaparin responsiveness in polytrauma patients

Quick Hits:

1.     On adjusted analysis, the standard VTE PPX plus aspirin group had a lower OR of developing VTE, though limitations of this study highlight need for future prospective work
2.     Trauma patients often suffer from decreased activity of antithrombin 3, which may mediate the relatively higher rates of VTE in this population.
3.     Trauma patients who went on to develop VTE were more likely to not achieve satisfactory anti Xa levels, with a VTE rate of 30% in the never-responder group, the group for which Xa levels were never higher than 0.2
4.     Ex vivo supplementation of antithrombin seems to improve enoxaparin responsiveness.  Remember, enoxaparin and heparin are HELPING AT3, not the other way around

Behind the Knife is a podcast aimed for everyone interested in not only an in-depth look at the broad range of surgical topics, but a "behind the scenes" look at the interesting, controversial and humanistic side of surgery from some of the giants in the field. Come along with Kevin Kniery, Jason Bingham, John McClellan and Scott Steele on a journey that explores all the disciplines of General Surgery in this informal discussion and interview format. We feel that this is the perfect medium not only to cover important educational topics for all stages of your professional career, but allow you to listen to a first-hand account of not only where we have been from those that pioneered the way, but also an opportunity to explore where we are now and are headed in the not so distant future from surgical leaders.
