Passed wind, asleep and sedated at last (7)
I believe the answer is:
elapsed
'passed' is the definition.
('elapse' can be a synonym of 'pass')
'wind asleep and sedated at last' is the wordplay.
'wind' indicates anagramming the letters.
'and' says to put letters next to each other.
'at last' suggests the final letters.
The last letter of 'sedated' is 'd'.
'asleep' with letters rearranged gives 'elapse'.
'elapse'+'d'='ELAPSED'
(Other definitions for elapsed that I've seen before include "Passed, of time" , "slipped away" , "Pleased to have passed" , "Went by" , "Pleased (anag.)" .)
