During placement of an epidural in an elderly patient with sharp pain radiating down the leg as the catheter is inserted to 2 cm, what is the most appropriate action?

• A. Leave the catheter at 2 cm, give test dose
• B. Withdraw the catheter 1 cm, give test dose
• C. Withdraw needle and catheter, reinsert in a new position
• D. Abandon epidural technique, place long-acting spinal anesthetic

Answer: (C)

When a sharp, shooting pain radiates down the leg as the epidural catheter is advanced, it means the needle or catheter is contacting a nerve root or entering near neural tissue. Paresthesia during neuraxial placement is a warning sign that continuing to advance could injure a nerve or lead to an unintended intrathecal or intraneural injection. The safest and most effective response is to withdraw both the needle and the catheter completely and reinsert them in a new position, ideally at a different interspace or with a different trajectory, using the loss-of-resistance technique to ensure the epidural space is entered correctly. Once a fresh position is established and proper placement is confirmed, you can proceed with a test dose if appropriate. Keeping the catheter in place or proceeding with a test dose at this point risks nerve injury or inappropriate anesthetic spread. Abandoning the epidural for a long-acting spinal is unnecessarily invasive when a repositioned epidural attempt can be successful.
