Intraoperative ST segment, T wave changes in two infants during general anesthesia

When compared to the adult population, intraoperative cardiac events related to coronary ischemia are uncommon in the pediatric population. However, continuous electrocardographic (ECG) monitoring is still recommended in infants and children.  The authors report two infants who developed intraoperative ST-T wave changes during routine surgical procedures.  The role of intraoperative ECG monitoring in infants and children is discussed, the etiology of ST-T wave changes is presented, and previous reports of such events are reviewed.
