To determine the association between the presence of upper respiratory tract viral infection symptoms and occurrence of perioperative respiratory adverse events (PRAE) in children with positive viral screening, and to analyze the risk of PRAE in children with SARS-CoV-2 compared to non-SARS-CoV-2 infection. ⋯ There was no significant difference in the incidence of PRAE between symptomatic and asymptomatic children with laboratory confirmed viral respiratory infection, and between children with the Omicron variant of SARS-CoV-2 compared to non-SARS-CoV-2 respiratory viruses. However, the risk was increased in children with recent fever.

To assess the incremental contribution of preoperative stress test results toward a diagnosis of obstructive coronary artery disease (CAD), prediction of mortality, or prediction of perioperative myocardial infarction in patients considering noncardiac, nonophthalmologic surgery. ⋯ Cardiac stress testing before noncardiac, nonophthalmologic surgery does not improve predictions of either perioperative mortality or myocardial infarction. Very few patients considering noncardiac, nonophthalmologic surgery have a pretest probability of CAD in a range where stress testing could usefully select patients for angiography. Better use of existing patient data could improve predictions of perioperative adverse events without additional patient testing.
