In brief: Varies

Some will last about an hour, some for about 24 hours, and a newer type has the potential of lasting for up to 3 days.

In brief: Varies

Some local anesthetics wear off within 30 minutes, while other are specifically designed to be active for up to 20 hours.
It depends on the type and location of the drug. Talk to your anesthesiologist about medications that they will use.

In brief: Depends...

Local anesthetics vary in duration both in terms of their chemical structure (Bupivicaine lasts longer than Lidocaine, for example), whether they have adjuncts added to them (Epinephrine will prolong action), and where they are actually injected.
Simply, the greater the blood supply to the area administered, the shorter they will last. So, an hour to 8 hours or more...
