Built by Anesthesia Providers, For Anesthesia Providers
Primaxis delivers real, clinical value where it counts.
It Started With a Simple Need: Fast, Reliable Answers
It's 2 AM. You're heading upstairs to place an epidural—one you haven't done in three months. You have the skills. You have the experience. But you want to verify the dosing and recall all the points to hit with informed consent quickly before you walk into that room.
You pull out your phone and start searching:
Vargo gives you lists of related pages to scroll through—but which one has what you need?
OpenEvidence shows research snippets—but you have maybe 60 seconds, not 15 minutes.
UpToDate floods you with a comprehensive background—when all you need is the protocol.
ChatGPT tries to help—but doesn't understand anesthesia context, and you can't trust it without real citations.
That's when Chris Cataldi, CRNA, asked himself:
“What if there was an AI assistant that actually understood what I'm asking? That had expert-level anesthesia knowledge at instant recall? That gave me the answer—not another research assignment?”
Primaxis is that answer.
Not another generic AI tool.
Not another reference database that makes you do the work.
A clinical colleague who understands anesthesia workflows. Who speaks your language. Who's there when your actual colleagues aren't.

selection, even explaining procedures to patients.”
Meet the Founder
Chris is a practicing CRNA at a variety of sites in Western New York with more than a decade of anesthesia experience.
He built Primaxis because he lived the problem: working solo cases where you need an answer immediately, but there are no colleagues around to ask, or your partners are busy with their own cases, and Google isn't good enough.
Chris combines clinical expertise with technical skills in AI development, creating tools that actually fit into anesthesia workflows—not generic solutions that require you to adapt.
