Day case general anaesthesia in a patient with narcolepsy.

We report a patient suffering from narcolepsy who presented for day case gynaecological surgery under general anaesthesia. Her symptoms were normally well controlled using modafinil therapy which she had omitted on the day of surgery. Modafinil is a unique drug and has potential for many interactions with anaesthetic agents; these are discussed in this report. Her anaesthetic course was uneventful and we review previous reports of patients suffering with narcolepsy undergoing anaesthesia and suggest that narcolepsy should not be a contra-indication to day case surgery.
