The dangerous local anesthetic dose is rarely a single injection. It is the field block plus the surgeon's infiltration plus the mix you ran earlier, each one defensible alone and alarming added up. Per-drug math will not catch that, because the risk lives in the total.
This calculator keeps the total in view. Add each contributor, presets or the custom mixes you have saved, and it sums the toxicity across all of them on one screen: a gauge for the overall picture, each drug's share of the load, and a collective-aware read on how much room is left before 100 percent.
It also handles the traps that trip people up. Liposomal bupivacaine is counted as bupivacaine, the mixes you built carry their real composition into the total, and a tap on the rationale explains what is driving the number. It is the one screen that answers the only question that matters: across everything, how close is this patient to the edge?
