Local anesthetics

Although based on moderate evidence, the addition of dexamethasone can prolong the analgesic effect of the nerve block and reduce opioid consumption.

Dose : 4-8 mg mixed with your ropivacaine or bupivacaine syringes OR 8 mg IV (more systemic effect but less complex since no need to mix).

Formulation to use: Single-dose formulations are preferred. These do not contain preservatives, unlike multi-dose formulations, which can be toxic to nerves.
