Question

A 70-kg patient is having a left lung partial lobectomy for lung cancer. He consents for general anesthesia with the addition of a left intercostal nerve block for postoperative pain management. What is the maximum dose in milligrams of lidocaine 2% (Xylocaine) with epinephrine for this patient's block?

A. 70
B. 140
C. 350
D. 490

Answer 1

The maximum recommended dose of lidocaine 2% with epinephrine for a 70-kg patient is 490 mg, calculated as 7 mg/kg, which aligns with Option D.

Step-by-step explanation:

The maximum recommended dose of lidocaine 2% with epinephrine for a patient is generally 7 mg/kg when used for nerve block procedures, with a maximum suggested limit of 500 mg. For a 70-kg patient, you would calculate this by multiplying 70 kg by 7 mg/kg. Therefore, the maximum dose for the patient would be 490 mg.

It's essential to consider factors such as patient health, concurrent medications, and the specific requirements of the surgery. But based on the question, the correct answer for the maximum dose is 490 mg, which corresponds to Option D.
