Anesthesia Dosage CLI (Go)

Author: Moses G. Olson, MD
Copyright © 2020

A Linux/CLI program written in Go. It takes patient weight (kg) and age (years) and prints common anesthesia-related dose estimates, including max-dose caps for several drugs, plus age-adjusted MAC values for sevoflurane, desflurane, and isoflurane using the Mapleson meta-analysis formula.

Educational / historical software only. NOT for clinical use. Always verify doses with current protocols and clinical judgment. This page recreates the 2020 program's calculations for demonstration; it is not a medical device and must not guide patient care.

Source

anesthesia/main.go — main program
anesthesia/aduAnes/constants.go — dose constants (mg/kg) and MAC baselines

How to run locally

The original module import path is "anesthesia/aduAnes". Place the sources so that package layout matches that path (e.g. a module named anesthesia with subdirectory aduAnes), then:

go run . <weight_kg> <age_years>
# example:
go run . 70 40

With fewer than two numeric arguments, the program prints a short help / copyright banner and exits.

In-browser runner

Same calculations as main.go (constants, max-dose caps, and MAC formula with coefficient -0.002679). Output mimics the CLI text.

Enter weight and age, then press Calculate.
