Hospital enemas in Britain

Was in chat here a few days ago with a guy and were discussing enemas as given in uk hospitals in the past.

I said id seen many years ago on tv, a documentary type programme, where retired nurses were telling how enemas were given and what they consisted of, oh how i wish i knew where to find any parts of that documentary ? must have been 20 ish years ago, and back then there were only about 4 channels to watch, BBC1 and 2 , itv and channel 4....if it was around ten, ive tried googlng it etc, no luck, anyone out there remember it, where it was, and how to see it again and record it ?
