Appalling treatment in resuscitation room? (8)
I believe the answer is:
shocking
This clue is a double definition.
'appalling' is the first definition.
('shock' can be a synonym of 'appal')
'treatment in resuscitation room?' is the second definition.
(as in defibrillating with an electric shock)
(Other definitions for shocking that I've seen before include "form of execution?" , "Horrific (pink?)" , "Dreadful (shade of pink?)" , "result of bad wiring?" , "Traumatic" .)
