Colonoscopy :: Inaccurate Information And How The Sedation Can Make It Worse

I had a colonoscopy with sedation (midazolam and fentanyl) in Chorley Hospital a few days ago and I still feel as if I had a PTSD. I read the information sheet and expected to be relaxed after sedation, with maybe some discomfort. When I was injected with the drugs (midazolam and fentanyl), I suddenly felt very anxious. I tried to seek reassurance, but the physician was talking to somebody else, busy preparing for gastroscopy. I think it could have helped if somebody asked me how I was at that point. I also had some trouble speaking – I think I was able to speak, but I could not hear myself so it made me feel very strange. Later on I read that difficulty speaking is a side-effect of midazolam. I felt quite intense pain during colonoscopy and the kind student nurse was talking me through it. I recovered well, I think, but I remember the whole procedure (so the amnesia that the leaflet talks about obviously doesn’t happen in every case). Next day I was very irritable and anxious and sick later on.

My main grievance is about lack of information beforehand concerning pain and the nasty side effects of the sedation. The leaflet mentions that you might feel ‘discomfort’. Of course you will feel discomfort – you will have a camera up your bum, what are supposed to feel? There is no ‘may’ about it. However, there is a difference between ‘discomfort’ and ‘pain’ and these words should not be used interchangeably. The leaflet and what you are told by the medical staff makes you believe that you will be drowsy and relaxed while medication works, and then back to normal after. I got quite a shock when I had the anxiety attack after the drug was injected and realized how vulnerable and helpless I was. I was also very unpleasantly surprised at how awful I felt the next day. Had I known this could happen I would have opted for entonox. Unless something changes dramatically in the way they perform colonoscopies, there is no way I’m having another one any time soon.

I would not like to discourage those for whom colonoscopy could be beneficial from having it. However traumatic it is, it is preferable to dying from cancer. However, I think that medical staff are not well trained in empathy (only student nurses seem to have it) and you have to be very assertive with them in order to receive honest information. If you are unlucky enough not to experience post-colonoscopy amnesia, the feeling of being at the mercy of medical people who are inflicting pain on you can be disturbing. It might be preferable to experience the pain whilst being alert and able to speak, and thus having some degree of control.
