Anaesthesia for insertion of bone-anchored hearing aids in children: a 7-year audit.

Abstract

Forty-three children, aged 23 months to 14 years, received 102 anaesthetics for insertion of bone-anchored hearing aids, each lasting approximately 30-60 min. Forty of the children had a recognised syndrome involving the head and neck, including Goldenhar's and Treacher Collin's syndrome. The incidence of congenital heart disease was 19%. Pre-existing conditions, anaesthetic technique, grade of intubation, complications and discharge were audited. Sixteen of the patients were classified as Grade 3 or 4 intubations. Over the 7 years, laryngeal mask airway usage increased for airway maintenance rather than tracheal intubation, as did the use of propofol for induction rather than inhalational methods. Intra-operative complications (5.9%) were related to the airway, and postoperative ones (17.6%) mainly to nausea and vomiting. Surgery was performed as a day case in 71% of the patients despite some long-distance travel.
