Q11 Risk assessment for respiratory complications in paediatric anaesthesia


(modified from von Ungern-Sternberg BS, Boda K, Chambers NA et al. (2010) The Lancet 376: 773–83)


Respiratory adverse events in children are one of the major causes of morbidity and mortality during paediatric anaesthesia. The aim of this study was to determine whether there is an association between a family history of asthma and occurrence of perioperative (during anaesthesia or recovery) respiratory adverse events. 9,297 children who had general anaesthesia for surgical or medical interventions at a hospital in Perth, Australia, between February 2007 and January 2008 were included in the study. Before surgery a questionnaire was completed based on the medical history of the patient, including whether there was a family history of asthma. Children were monitored during anaesthesia and time in the recovery room, for any respiratory event including laryngospasm, bronchospasm, airway obstruction, oxygen desaturation (<95%), and severe or sustained cough.
