Anesthesia caused by the elimination of sensory inputs from dorsal nerve roots after drugs are introduced into appropriate regions of the epidural space.
In an epidural block, an anesthetic agent is injected into the extradural (epidural) space. It diffuses through the dura and arachnoid, entering the subarachnoid space containing CSF. It acts on the nerve roots and the spinal cord causing loss of sensation below the level of the block. While it is very unlikely to affect the fetus during childbirth, it is effective in preventing pain. Chronic lower backache is also treated with an epidural block.
An anaesthetic technique that reduces pain during childbirth without altering the mother's level of consciousness. This type of local anaesthesia is often given during labour to relieve the pain of contractions and delivery. A needle is inserted through the skin of the back into the epidural space. Anaesthetic is then injected around the spinal cord which anaesthetises the nerves of the lower part of the body
a commonly used form of regional anesthesia for labor and birth
Anesthesia that numbs the lower half of the body.
The injection of anesthetic into the epidural space in order to block or desensitize a specific nerve at particular points of a nerve pathway.
A procedure where pain medications or steroids are injected into "epidural space" in the neck, middle and lower back, just outside the spinal space, to treat pain.
An injection which can be used as a treatment as well as a diagnostic tool to help locate the source of pain. The test is conducted in the Radiology Department by an anesthesiologist, physiatrist, or an orthopedist. The patient is also evaluated before and after the test by either the physician, nurse, or physical therapist. As the patient lies on his/her stomach, the physician anesthetizes either the lumbar or tailbone area. This procedure is similar to a novocaine injection given by a dentist. Another needle is then injected into the appropriate area and injections of various medications are given. At times, the physician may use a dye to help trace the flow of medication. The procedure takes approximately 30 minutes. The patient should alert the physician or nurse if allergic to shellfish, iodine, cortisone, or anesthetic.
An injection of an anesthetic drug given into the space between the wall of the spinal canal and the covering of the spinal cord.
an injection of anesthetic solution into the membrane (dura) surrounding the spinal cord to numb the lower body during labor and childbirth
