Perfusion Policies 101: Anticoagulation Reversal

Renee Toth, BS, CCP   Editor’s Note: Renee is a colleague I work with quite often.  She is an amazing perfusionist as well as administrator, mom, and just a decent all around human being. She has a pretty scathing wit- so beware.  She offered to share a policy she has worked on for a quite […]

Why is my Patient Bleeding? A Snapshot of Hemostasis, Part II

Click on image to view source article Editor’s Note: We have all revisted this pathway intensively throughout our careers, and of course, we have all been clinically challenged by open-heart cases that test our fundamental understanding of coagulation theory in real time, at a level that certainly reflects a fairly deep dive into esoteric hematology. So i am keeping it simple, and found […]

Perfusion Policies 101: Angiomax

Editor’s Note: The use of alternatives to heparin in terms of managing anicoagulation doesn’t come up often.  It’s easy to get a bit rusty when it comes to using exotic agents such as Ancrod (Hirudin), Angiomax and similar agents. So here is a brief refresher, and as always- a disclaimer here:  Use this information with […]

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 […]

Angiomax: Use and Dosing Regimen

Editor’s Note: The use of alternatives to heparin in terms of managing anicoagulation doesn’t come up often.  So many of us get a bit rusty when it comes to using exotic agents such as Ancrod (Hirudin), Angiomax and similar agents. So here is a brief refresher, and as always- a disclaimer here:  Use this information […]

Cairo, Egypt: Case Study: AVR with Antiphospholipid Syndrome

Editor’s Note: I saw this post of Ramy’s FB page (or maybe one of the perfusion groups on FB) and reached out to Ramy to submit this as a case study.  He has graciously forwarded the case study and I thank you Ramy. Feel free to leave comments in the comments section- Happy Saturday 🙂 […]

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 […]

Heparin: Factors Affecting & it’s Effects [Reprint]

HEPARIN ONSET: Maximal at 1 minute past atrial delivery: Measured at radial artery.  Note:  10-20% reduction in svr without affecting c.o. and or h.r. LUNG VS MUCOSAL: Mucosal requires larger doses- but can be reversed with 25-30% less protamine:  greater postoperative blood loss associated with mucosal heparin- speculated to result from lower molecular weight & […]

Heparin Metabolization or AT3 Deficiency ?

There has been a drive lately to reduce the amount of heparin administration during bypass at a couple of institutions I have been at. I’m all for that, although some of the parameters placed before us are clearly unrealistic and forwarded by people that know nothing about perfusion except what they have read in a […]
