Bupivacaine is about 95% bound to plasma proteins, mainly to alpha-1-acid glycoprotein at low concentrations and to albumin at high concentrations. In adults, the terminal half-life of Bupivacaine is 2.7 hours. In neonates and some young infants, terminal elimination half-lives could be as long as 8 to 12 hours.

Marcaine Dosage. In obstetrics, only the 0.5% and 0.25% concentrations should be used; incremental doses of 3 mL to 5 mL of the 0.5% solution not exceeding 50 mg to 100 mg at any dosing interval are recommended. Repeat doses should be preceded by a test dose containing epinephrine if not contraindicated.

What’s the correct dosage of Marcaine for nerve block?
0.5%— provides motor blockade for caudal, epidural, or nerve block, but muscle relaxation may be inadequate for operations in which complete muscle relaxation is essential. 0.75%—produces complete motor block.
