Summary Dental anaesthesia provides a potential conflict between anaesthetist and surgeon because of the shared airway. The laryngeal mask airway (LMA) has helped to improve airway control for these procedures, but there is little evidence for best practice on the timing of their removal after airway surgery in the paediatric population. We compared ‘awake’ and ‘deep’ removal of the LMA in 196 patients aged from 2 to 15 years in a randomised, controlled study. We found that average peripheral oxygen saturation (SpO 2 ) was lower in the deep group and this was statistically significant (96.2% vs. 94.9%, p = 0.04). It was also found that the deep group had a higher incidence of patients with SpO 2 < 95% (p = 0.003) and of patients who coughed (p = 0.003). We conclude that the LMA should be taken out awake in these patients.
