Body Weight & Drug Dosing

Ideal, lean and adjusted body weight — and which weight to dose each anaesthetic drug to.

Draft — not yet clinically verified. Drug-to-weight mapping from the SOBA single-sheet guideline (2022). IBW = Broca; ABW = IBW + 40%; lean body weight uses the Janmahasatian formula. A guide only — for TIVA always combine with an appropriate PK model, and check drug SPCs (e.g. sugammadex). Not a substitute for clinical judgement.
