I really feel for your husband. I had vulvar surgery at 21 and was asked to crawl down a surgical trolley into right position with no underwear on, only a gown, during a heavy period. There were students, nurses and several doctors involved because it was all a bit complex. I spent I think two hours with legs in stirrups, sedated.
When I came round every so often - as the sedation kept dropping - the number of people in the room kept changing and most of them never introduced themselves, even those at the business end. I was wheeled out with no blanket, hand on my fanjo holding a pad on. Everyone on my ward knew what was wrong - because I had no buzzer, and I had to shout to nurses that I was sore, needing bedpan, or bleeding etc.
I felt as if my brain had detached and was watching someone else. Felt they were looking after my body and not me, iyswim. I didn't want to be involved at all.
I have never gotten over it. Have all sorts of problems and probably will end up back in therapy at some stage.
Two years later I was required to undergo very similar. I was sobbing at the thought. I was shocked when the nurses and anaesthetist let me keep a blanket, and locked the door, and introduced me to all the staff. At no time did they force me to sit in that state for longer than I needed. I was so overwhelmed that I ended giving the anaesthetist and surgeon hugs afterwards.
I still feel shocked when in hospital and given blankets, etc and helped to cover up. In A&E in January, when I ended up with severe thrush, the doctor and nurse helped me cover myself and I was crying with relief.
I'm currently applying for NA and HCA jobs and the biggest thing for me - dignity. If a patient doesn't need to be nude, don't have them nude. If there's a blanket, use it. Say hello to the patient, tell them who you are. I had to let all sorts of people - male and female - gawp at me (students certainly were) and had no idea who they were or what their role was. Don't shout to the ward what you're doing or what's wrong with the patient, unless it's a dire emergency. Simple things that can make all the difference. I don't remember the names of the nurses who looked after me the second time but I knew them when I needed to iyswim, and felt so much better.
There's a head and a mind attached to the body, that will know, feel and usually remember. It makes a huge difference feeling secure and fully cared for.
