TEG vs ROTEM? A Brief Comparison AND a Survey?

Click image above to take ROTEM Survey 🙂 Editor’s Note: I was asked by a reader to do an article on thromboelastograms.  Wasn’t sure what approach to take in this regards so decided to do a brief intro and switch the focus in particular to a comparison and differentiation between the two prevalent systems, the TEG and the […]

The TEG (Thromboelastogram)

Editor’s Note: Recently we began employing the TEG routinely for all of our open-heart procedures.  Now I am relatively familiar with the concept, having discussed and written about it before.  However there is an array of numbers and categories that come with the TEG analysis that I wasn’t certain about, so to clear it up […]

On CPB- Heparin Protocol Survey

Editor’s Note: I received a note from a perfusionist the other day regarding heparin administration, and how it has become regulated at their institution.  It was significant enough- in terms of it’s implications of our ability to manage patients on bypass for me to pass on the concern, and as well- develop a survey to […]

Hemostasis Assays [v.1]

Partial Thromboplastin Time (Activated) The activated partial thromboplastin time (aPTT) is test that overlaps the prothrombin time (both evaluate the common pathway), and is designed to isolate the intrinsic pathway.  While these tests are similar, the aPTT utilizes kaolin or cellite and cephaloplastin to stimulate the intrinsic pathway.  This pathway is the longer of the […]
