Tume LN, et al. - An observational study was conducted to examine processes and adverse events associated with endotracheal suctioning in the first 48 hours after 3 surgical procedures: the Norwood or Norwood-Sano procedure, pulmonary artery banding, and the modified Blalock-Taussig shunt. Investigations revealed that significant hemodynamic instability and adverse events occur during routine suctioning in infants with single-ventricle physiology after surgical palliation.
