N: 1. – epidural (adj): 1873, «situated on or affecting the dura mater,» from epi- «on» + dura mater + -al. The noun meaning «injection into the epidural region» (usually given during childbirth) is attested by 1966.
– anesthesia (n): 1721, «loss of feeling,» medical Latin, from Greek anaisthēsia «want of feeling or perception, lack of sensation (to pleasure or pain),» abstract noun from an- «without» + aisthēsis «feeling» (from PIE root *au- «to perceive»).
As «a procedure for the prevention of pain in surgical operations,» attested from 1846. Aesthesia «capacity for feeling» is attested in English from 1853, perhaps a back-formation.
