Which local anesthetic's use is restricted due to potential neurotoxic effects?

• A. Bupivacaine
• B. 5% lidocaine
• C. Procaine
• D. Chloroprocaine

Answer: (B)

The local anesthetic whose use is restricted due to potential neurotoxic effects is bupivacaine. This anesthetic is known for its long duration of action and high potency, making it a preferred choice for various surgical and anesthetic procedures. However, it has been associated with a higher risk of neurotoxicity compared to other local anesthetics, especially when used in high concentrations or in certain patient populations. Bupivacaine's toxicity can lead to severe complications such as prolonged motor and sensory block, which is a particular concern in regional anesthesia, especially when administering epidural or nerve blocks. The neurotoxic potential may manifest as symptoms such as persistent numbness or weakness after the effects of the anesthetic should have resolved. As a result, clinicians must use caution when selecting bupivacaine, taking into account the dosage and the individual patient's risk factors. The use of high concentrations of lidocaine, while possible, is generally less associated with neurotoxic effects than bupivacaine. Procaine and chloroprocaine have also been found to have a more favorable safety profile when it comes to neurotoxicity, leading to their continued use in various settings without significant restrictions related to neurotoxic concerns.
