September 2021 Quick Question: TEG

September 2021 Quick Question: TEG
Sep 30, 2021 12:05pm

Our September 2021 Quick Question attracted only 14 responses, perhaps reflecting the minimal communication between the central laboratory and the anesthesiology service in most operating rooms. Our question was "What is the favorite near-patient viscoelastic test of US anesthesiologists?" Here are your answers:

  1. Rotational thromboelastometry [ROTEM ]: 14% [2]
  2. Resonance sonorheometry [Quantra]: 7% [1]
  3. Activated clotting time [ACT ]: 0%
  4. Thromboelastography [TEG ]: 79% [11]

This topic arose when the anesthesiology service at a nearby facility requested a presentation on thromboelastography. We've found that the ROTEM is popular in Europe whereas the TEG is used in North American operating rooms and more recently in emergency departments, mainly to manage heparin and blood component therapy. The Quantra is a recent entry in the viscoelastometry science from HemoSonics, and, while not on our list, the time-honored Sonoclot has a worldwide distribution. The near-patient ACT , while employed in most cardiac surgery suites to monitor hypertherapeutic heparin levels, is a modification of the long-obsolete Lee-White coagulation time, not a global viscoestometry assay.
