General anesthesia is the induction of a state of unconsciousness, amnesia (loss of memory), and analgesia (absence of pain sensation) over the entire body, through the administration of anesthetic drugs. It is used during certain medical and surgical procedures.
Type of regional anesthesia produced by the injection of a local anesthetic into the epidural space (just outside the membrane that protects our spinal cord) of the lumbar or sacral region of the spine (lower back). Patient feels numbness from the abdomen or pelvis downward and is used especially to control pain during childbirth. Often a very small tube or catheter is left in place so you can receive more mediation as needed.
