Zhang S, et al. - The impact of recent upper respiratory tract infection (URI) on perioperative outcomes of congenital heart disease (CHD) children who underwent elective therapeutic catheterization, was determined. Laryngospasm, bronchospasm, breath holding, oxygen desaturation, and severe cough were recorded as perioperative respiratory adverse events (PRAEs). Age, passive smoking, and presence of rhinorrhoea or moist cough were reported as independent risk factors for PRAEs in this patient population. The incidence of PRAEs was increased by recent URI but most CHD patients with recent URI can undergo elective therapeutic cardiac catheterisation without serious adverse events or prolonged hospitalisation.
