Feeling faint, usually a vagal episode can happen to us all. I recall as a young med student going to theatre for the first time. A child was having a closure of patent ductus arteriosis. A vessel present in the neonate that usually closes at child birth. So patient is on their side with chest open. It was very dry, nice dissection by the cardio thoracic surgeon, and as much as I tried to intellectualise what I was seeing, I came over faint. It was very embarrassing because another member of the team had to help me and not concentrate on the task at hand. But these things happen, you try not to take them to heart. Fortunately it didn’t put me off spending a life time in theatre.
