Thanks obgraham and Angiojet
This forum should be for pilots asking questions, not us lot having our usual ready room banter but I did do a search before posting and the outcome was the same for both procedures, but little data on downside with embolisation. The punters need our advice and we cant tell them we cant advise because the guidelines are unclear.....
In most countries 'a smidgeon of midazolam' needs an anaesthetist and in many countries organising this in radiology is a nightmare. In the US many surgeons and radiologists give their own sedation or leave it to a nurse or technician. We dont allow that elsewhere for very good reasons. So location plays a part! although in Maui it would not be an issue!
For any pilots still following this, it is a good example of the adage
ask 2 doctors and you get 3 opinions
and underlines the fact that this site can only give general advice and can never replace a face to face with your own doctor!
