title: Intraoperative respiratory complications in patients with upper respiratory tract infections.
abstract: A retrospective survey of 3,585 patients aged newborn to 20 years was performed to investigate the prevalence of intraoperative respiratory complications in patients with symptoms of upper respiratory tract infections (URIs). There were no significant differences in complication rates between asymptomatic patients (1.61 per 100) and those with symptoms (1.64 per 100); however, patients who were asymptomatic but had a recent history of an URI had a significantly higher complication rate (5.31 per 100; p less than 0.05) than the asymptomatic patients. There were no significant differences in intraoperative complications between patients managed with and without tracheal intubation, nor was there any association between the type of anaesthetic agent used and the development of intraoperative respiratory complications. Results from the study suggest no increased risk of respiratory complications for patients presenting with uncomplicated URIs. However, patients who were asymptomatic but had a recent history of an URI showed a significantly increased risk for the development of intraoperative complications.
