What are the routes of administration for Lidocaine?

• A. IV/IM
• B. IV/PO
• C. IV/IO
• D. IM/Subcutaneous

Answer: (C)

Lidocaine can be administered through several routes, with intravenous (IV) and intraosseous (IO) being particularly important for its therapeutic effects. The IV route allows for rapid onset of action, making it ideal for emergency situations, such as the treatment of arrhythmias or during cardiopulmonary resuscitation. The IO route is also significant in emergencies, especially when IV access is challenging or unavailable; it enables the drug to be delivered directly into the bone marrow and into systemic circulation quickly. While Lidocaine can be absorbed through other routes, such as intramuscular (IM), the key therapeutic applications in acute care emphasize IV and IO as more effective routes for delivering the drug swiftly, which is why this combination is the correct answer. Other potential routes like subcutaneous or oral (PO) are not as commonly used in critical situations where rapid action is required, making them less relevant for the primary uses of Lidocaine in emergency medicine.
