What is the dose range for a lidocaine drip in adult patients?

The proper dose range for a lidocaine drip in adult patients is between 20 to 50 mcg/kg/min. This range is commonly used in clinical practice for managing certain arrhythmias, particularly ventricular tachycardia and prevention of ventricular fibrillation, as well as for analgesia, especially in the context of procedural sedation or pain management.

When administering lidocaine, maintaining this dose range helps achieve therapeutic effectiveness while minimizing the risk of toxicity, which can lead to side effects such as neurological disturbances. Since lidocaine is a sodium channel blocker, appropriate dosing is crucial to ensure that it successfully stabilizes the cardiac membrane without causing adverse reactions.
