DEC

decanestesia.org — home of the DEC ecosystem

The art of nothing happening.The science of making sure.

Clinical apps, calculators and study material for anesthesiologists who would rather calculate than guess. Everything else lives on the dark side.

Illustration: a man in a shirt and tie sitting on a park bench under a gray sky, covered in cobwebs from waiting so long.
The gentleman on the bench has held that pose since this site's first version. The cobwebs are real — except over his heart, which someone keeps awake. The curious, now and then, feel it beat.

Immediate use

Clinical calculators

Four OR calculators, free and registration-free. In Spanish for now — they live at the same URLs they always have, in case you bookmarked them.

General calculatorQuick OR doses and calculations. Hypertonic saline (3%)Sodium is corrected with decimals, not hunches. ROTEM / TEG 6sViscoelastic testing, no crystal ball required. Fluid replacementWhat goes in, what comes out, and what gets lost on the way.

Clinical support tools: they help you decide, they don't decide. Verify every result before administering it — the signature on the anesthesia record is still yours.
