History and Etymology for narcosis

borrowed from New Latin narcōsis, borrowed from Greek nárkōsis "benumbing," from narkō-, variant stem of narkoûn "to benumb, deaden" (verbal derivative of nárkē "numbness, lack of sensation," of uncertain origin) + -sis -sis

Note: Greek nárkē has been compared with Old High German in-snerahan "to tie up (to), link (to)," hypothetically reflecting an Indo-European verbal base *snerk- "draw together, loop around" (thus Lexikon der indogermanischen Verben, 2. Auflage, Wiesbaden, 2001; see snare entry 1), but the semantic connection is far from apparent. (The Lexikon inaccurately translates nárkē as "Krampf, Lähmung" = "cramp, paralysis.") R. Beekes (Etymological Dictionary of Greek, Brill, 2009) regards the word as most likely of pre-Greek substratal origin.
