Do COVID-19 Pandemic-Related Behavior Changes Affect Perioperative Respiratory Adverse Events in Children Undergoing Cardiac Interventional Catheterization?

Abstract Background: The Novel Coronavirus Disease (COVID-19) pandemic-related behavior changes could affect the perioperative respiratory adverse events in children with congenital heart disease (CHD). This study was designed to compare the incidence of perioperative respiratory adverse events (PRAEs) in children with and without upper respiratory infection (URI) undergoing the cardiac catheterization before and during COVID-19 pandemic.Methods：COVID-19 was outbreak in January 2020 in China. 260 pediatric patients scheduled for elective therapeutic cardiac catheterization were included from January 2019 to March 2021 and 154 were completed during the pandemic. Recent URI was diagnosed by the attending anesthesiologist owing to different PRAEs incidence in non-URI and URI children. The overall incidence of PRAEs (laryngospasm, bronchospasm, coughing, airway secretion, airway obstruction, and oxygen desaturation) in non-URI and URI children undergoing the elective cardiac catheterization were compared before and during the COVID-19 pandemic. Logistic regression model was fitted to identify the potential risk factors associated with PRAEs.Results: Of 564 children enrolled, 359 completed the study and was analyzed finally. URI incidence decreased substantially during the COVID-19 pandemic (14% vs. 41%, P<0.001). Meanwhile, the overall PRAEs also significantly declined no matter whether or not the child had recent URI (22.3% vs. 42.3%, P=0.001 for non-URI and 29.2% vs. 58.7%, P=0.012 for URI respectively). Post-operative agitation in non-URI children occurred less frequently during the pandemic than before (2.3% vs. 16.2%, P=0.001). Behaviors before the COVID-19 pandemic (odd ratio=2.84, 95%CI 1.76 to 4.58) and recent URI (odd ratio =1.79, 95%CI 1.09 to 2.92) were associated with the PRAEs.Conclusions: COVID-19 pandemic-related behavior changes were associated with the reduction of PRAEs in non-URI and URI children undergoing elective therapeutic cardiac catheterization.
