Standing a round perhaps giving medical care (8)
I believe the answer is:
treating
This clue is a double definition.
'standing a round perhaps' is the first definition.
(paying for a round of drinks)
'giving medical care' is the second definition.
(Other definitions for treating that I've seen before include "Negotiating (with); handling" , "Giving medical care to" , "Discussing (a subject)" , "Standing a drink" , "Making no charge" .)
