I can understand that. Our old next door neighbour was was left on his own to look after a two year old son when his wife went to the dentist and came home in a wooden box. This was about 1970 though.Every General Anaesthetic carries a degree of risk, the risk is lower if you are healthy but complications can occur in anybody.
We used to be able to provide GAs ourselves but a few too many deaths led to a change in legislation so that now anaesthetics have to be administered by a anaesthesist.
However we can still provide IV and inhalation sedation.
