CRT
Rapid initiation
Citrated Rapid TEG — tissue factor plus kaolin activation. Fastest channel to results; CRT.MA gives an early read on clot strength and guides treatment faster than conventional coagulation tests

Nurse anesthesiology resident with a focused interest in trauma resuscitation and TEG 6s–guided hemostatic management.
About
Clinician first. Curious always.
I am a Doctor of Nursing Practice candidate in nurse anesthesiology at the University of Arizona, with clinical rotations across the Phoenix region — Banner University Medical Center, Banner Desert, and Valleywise. Before training, I spent years in the Trauma / Surgical ICU, caring for high-acuity trauma patients drawn from over 80,000 square miles of catchment.
My clinical and scholarly focus sits at the intersection of trauma anesthesiology and viscoelastic coagulation testing — specifically the use of TEG 6s with the Global Hemostasis with Lysis cartridge to drive goal-directed resuscitation when minutes and products both matter.

Clinical & Research Focus
TEG 6s in trauma — a bedside language for hemorrhage.
The Global Hemostasis with Lysis cartridge runs three assays in parallel — CK, CRT, and CFF — producing a profile of clot initiation, clot strength, fibrinogen contribution, and fibrinolysis from a single citrated sample. In trauma, that distinction reshapes the resuscitation.
CK
R time & MA
Citrated Kaolin — the workhorse channel. CK.R reflects clot initiation and points us toward plasma rather than reflexive platelet transfusion; CK.MA is the integrated read on overall clot strength.
CFF
FFMA — fibrinogen
Citrated Functional Fibrinogen — abciximab additive isolates the fibrinogen contribution to MA. FFMA reframes cryoprecipitate or concentrate as a goal-directed decision rather than empiric replacement.
LY30
Hyperfibrinolysis
Catching trauma-induced hyperfibrinolysis early changes mortality. LY30 operationalizes the antifibrinolytic decision in real time — a small number with outsized weight for the patient on the table.
“Goal-directed resuscitation is not just about giving less product. It is about giving the right product at the right moment — and being able to explain why at the end of the case.”
