Popis:	Summary The laryngeal mask airway (LMA) must be inserted during deep anaesthesia. There are no guidelines concerning the removal of LMA, i.e., in awake or anaesthetized patients. The aim of this randomized prospective study was to compare the incidence of respiratory complications after LMA removal in anaesthetized or awake paediatric patients. Sixty children (ASA PS I or II), ranging from 4 months to 12 years of age, were studied. In patients breathing spontaneously, anaesthesia was induced and maintained with nitrous oxide, oxygen and halothane. Patients were randomly divided into two groups: group 1 removal of LMA in awake patients, or group 2 removal of LMA in anaesthetized patients, i.e., in patients receiving halothane at an alveolar concentration of 2 MAC adjusted for age and oxygen for 5 min. In both groups, patients received 100% oxygen after removal of LMA. After removal the incidence of respiratory complications was highest (P < 0.05) in group 1. Therefore, in healthy children undergoing elective surgery, the authors conclude that it is safer to perform the LMA removal in anaesthetized patients.
