Not to worry, Kim: These may be slower to recover because they are also among the fingers affected by the carpal tunnel (compression of the median nerve). Also, depending on which blocking agent was used and other factors (like circulation, temperature), it may take up to a week for the full effects of the anesthetic/analgesic medications to wear off. If the numbness persists beyond one week, I'd get reevaluated

Usually the: block they use is a Bier block which isn't really a nerve block, it's intravenous, check with surgeon regarding the surgical procedure

The surgeon may have done a more localized block at the level of the wrist. Bier blocks aren't often used for carpal tunnel surgery in many hospitals. With long-acting local anesthetics, numbness may last 24 hours or longer.

May be expected: With long-acting local anesthetics, numbness and pain relief may last for 24 hours or longer. Check with your surgeon about what type of nerve block was used, and whether there is reason for concern if your fingers are still numb. Most likely the sensation will gradually return to normal.

Carpal Tunnel: Yes you should contact your surgeon. The local anesthetic would have worn off in 24 hrs. You may have some swelling around the Median nerve affecting your sensation,
