Day stay anaesthesia. A follow-up of day patients undergoing dental operations under general anaesthesia with tracheal intubation.

Ninety-five patients who had undergone extensive dental surgery as day-patients were followed-up by questionnaire. An unexpectedly high incidence of after-effects was found; 78% of the patients went home with at least one persistent symptom due to the anaesthetic. A particularly high incidence of headache was found. There appeared to be no correlation of the symptoms with age, sex or nature or duration of the operation.
