Advanced lab interpretation is about more than memorizing normal values -it’s about understanding why a test was ordered, what the result tells you about your patient, and how it changes your anesthetic management.
In this episode of My Favorite Learners, we break down the advanced laboratory testing SRNAs need to understand for the NCE, anesthesia clinicals, and future CRNA practice.
We cover platelet count and function, PT/INR, aPTT, anti-Xa, activated clotting time (ACT), fibrinogen, D-dimer, TEG and ROTEM, and how these tests guide clinical decision-making in anticoagulation, active bleeding, cardiopulmonary bypass, and massive transfusion.
You’ll also learn why massive hemorrhage requires you to think beyond hemoglobin -including ionized calcium, potassium, acid-base status, temperature, perfusion, and the overall physiologic picture.
Throughout the episode, we work through board-style scenarios involving high-dose heparin and ACT before cardiopulmonary bypass, persistent bleeding after protamine, critically low fibrinogen during postpartum hemorrhage, and choosing the appropriate laboratory test for different forms of heparin.
The goal isn't to ask:
“What is the normal value?”
It’s to ask:
“Why was this test ordered? What does it tell me about my patient? And what am I going to do with the result?”
Perfect for SRNAs preparing for the NCE, nurse anesthesia students studying advanced lab interpretation, and CRNAs reviewing perioperative laboratory testing and clinical decision-making.
My Favorite Learners - making anesthesia concepts make sense.
