Regional anesthesia allows a procedure to be done on a region of the body without your being unconscious.How long does it take for regional anesthesia to wear off?

- General anesthesia: Patient is unconscious and feels nothing. Patient receives medicine by breathing it or through an IV.
- Local anesthesia: Patient is wide awake during surgery. Medicine is injected to numb a small area.
- Regional anesthesia: Patient is awake, and parts of the body are asleep.
Frequently, there is less nausea from regional blocks and patients generally awaken faster after regional blocks. Regional blocks can also be used to reduce the pain after surgery. Generally, regional nerve blocks and catheter will provide better pain control than intravenous or intramuscular opioids (narcotics).

What is the primary disadvantage of regional anesthesia?
The disadvantages of regional anesthesia include hypotension, intraoperative discomfort, post-lumbar-puncture headache and the potential for neurologic and cardiac toxicity from local anesthetics.

Novocaine is no longer used due to the increased time it takes to work, how long it is effective and its chances of causing allergic reactions. Lidocaine and Septocaine are our preferred anesthetics due to their faster onset time, longer acting time and very minimal chance of allergic reactions.
