Mode of Action

Bupivacaine blocks both the initiation and conduction of nerve impulses reducing the permeability of neuronal membranes to Na ions resulting in inhibition of depolarization w/ resultant blockade of conduction. Dextrose is a monosaccharide that is used as a source of calories and water for hydration. It helps to reduce loss of body protein and nitrogen. It also promotes glycogen deposition in the liver.
