What is the maintenance infusion rate of Lidocaine after an initial dose of 1 mg/kg?

The correct answer regarding the maintenance infusion rate of Lidocaine after an initial dose of 1 mg/kg is based on established protocols for the use of this medication in managing certain cardiac conditions, particularly ventricular arrhythmias.

After the initial loading dose, the recommended maintenance infusion rate for Lidocaine is typically 2 mg/min. This is based on pharmacological studies and clinical practice that determine the optimal dosing to maintain therapeutic effects while minimizing potential toxicity. The infusion rate can also be expressed in drops per minute; with a standard administration set that delivers 60 drops per milliliter (gtts), this translates to 30 gtts/min.

This dosage aligns with common recommendations found in medical guidelines, confirming its appropriateness for continuous intravenous administration. Understanding this rate is crucial for emergency medical responders as it ensures effective treatment while allowing for precise delivery.

Other choices do not align with standard dosing protocols for maintenance infusion rates of Lidocaine, making them less suitable for clinical application following the initial loading dose.
