Optional, for percent of IBW
When to use
- Dosing drugs labeled by ideal or lean weight (for example aminoglycosides, some sedatives, neuromuscular blockers).
Pearls and pitfalls
- Below 5 feet (60 in), Devine subtracts weight and gives values under the base; institutions often use an alternative.
- Devine was published for gentamicin dosing, not as a measure of healthy weight.
Why use
IBW feeds most weight-based adjustments. ClinDose shows the inches calculation, so the result is easy to double-check.
