Local Anesthesia

Wednesday, December 21, 2011

Having surgery performed under local anesthesia involves having local anesthetic drugs injected into tissue to numb a specific portion of the body. Dr. Edward Hill tells us more about local anesthesia in todays 60 Second Housecall.

Dr. Hill:

Local anesthesia is a way to numb a specific area of the body so that a medical procedure can be done without causing pain.

Some operations, many dental procedures and different types of diagnostic tests can be done using local anesthesia alone.

Local anesthesia medications do not make a person sedated or produce unconsciousness. Using local anesthesia alone avoids the side effects of sedation medications and medications used to produce general anesthesia. Local anesthetic solutions often provide long-lasting pain relief to the area where they have been applied.

Topical anesthesia places or sprays a solution on the skin or a mucous membrane.

Local anesthetic injection, using a needle, numbs skin and the tissue that lies underneath.

Irrigation with local anesthetic solution, using a syringe, a catheter or another type of device, bathes the surrounding area and tissues.

Epidural analgesia, such as is used to relieve the pain of labor and childbirth, is a catheter-based way of giving local anesthesia medication that bathes selected nerves near the spinal cord.
