What is the maximum total dose of Lidocaine for stable Wide Complex Tachycardia treatment?

The maximum total dose of Lidocaine for treating stable Wide Complex Tachycardia is 3 mg/kg. This guideline is based on established protocols for cardiac arrhythmias, where Lidocaine is often utilized as an antiarrhythmic agent. The rationale behind the dosage limit is centered around balancing efficacy in controlling the arrhythmia while minimizing the risk of toxicity and adverse effects.

Administering Lidocaine beyond this threshold can lead to increased risks of side effects, including CNS toxicity such as seizures or cardiac issues like bradycardia and hypotension. Therefore, adhering to the 3 mg/kg guideline helps ensure patient safety while providing effective management of the arrhythmia.

This approach to dosing reflects a calculated balance between the therapeutic benefits of the medication and the potential risks, emphasizing the importance of adhering to established protocols in emergency medical care.
