What is the maximum cumulative dose of Lidocaine in adults during resuscitation?

The maximum cumulative dose of Lidocaine in adults during resuscitation is typically considered to be 3 mg/kg. This dosage is established based on clinical guidelines and manufacturer recommendations to ensure both effectiveness in the treatment of arrhythmias and safety to minimize the risk of toxicity.

Lidocaine acts as an antiarrhythmic agent, particularly useful in the setting of ventricular tachycardia and cardiac arrest due to its ability to stabilize electrical activity in the myocardium. Administering Lidocaine within the 3 mg/kg limit helps practitioners avoid potential adverse effects resulting from higher doses, such as central nervous system toxicity (manifesting as seizures or altered mental status) and cardiovascular collapse.

The understanding of Lidocaine's pharmacokinetics supports this cumulative maximum dose, as its metabolism may vary based on factors like hepatic function and the overall clinical status of the patient. It is crucial in a resuscitation scenario to balance the need for effective medication with careful consideration of the total dosage to keep the patient safe.

Other options exceed the generally accepted limits for Lidocaine in resuscitation, potentially leading to serious complications associated with overdose.
