The total dose administered within 1 hour should not exceed 200-300 mg. - Lower doses may be required for elderly patients, as well as patients with congestive heart failure or cardiogenic shock. - Intravenous drip infusion is administered at a dose of 20-50 mcg/kg/minute. For local anesthesia: - The usual dose is 5 ml to 10 ml of a 2% lidocaine solution. - For anesthesia of the brachial and sacral plexuses, 5-10 ml of a 2% solution is administered. - For anesthesia of fingers and limbs, 2-3 ml of a 2% solution is used. - The maximum dose of 2% lidocaine solution is 10 ml, and this dose should not be repeated within 24 hours. - For local anesthesia, the drug should be injected into highly vascularized tissues with caution to avoid intravascular administration.
