Spinal and Epidural Anesthesia
Epidural anesthesia is used for anesthetic for procedures involving the lower limbs, pelvis, perineum and lower abdomen. It is also possible to perform upper abdominal and thoracic procedures under epidural anesthesia alone.
The advantage of epidural over spinal anesthesia is the ability to maintain continuous anesthesia after placement of an epidural catheter, thus making it suitable for procedures of long duration. Following surgery, lower concentrations of anesthetic drugs can also be introduced to relieve surgical pain.
