Echocardiography Findings and Perioperative Outcomes in Children

Echocardiography Findings and Perioperative Outcomes in Children Undergoing Congenital Heart Surgery: Prospective Observational Study

This study evaluates the association between perioperative echocardiographic Doppler findings and clinical outcomes in pediatric patients undergoing cardiac surgery. In our center, anesthesiologists perform transthoracic or transesophageal echocardiography during perioperative period routinely in children undergoing surgery for congenital cardiac disease. Echocardiographic findings include the doppler patterns of hepatic vein, portal vein, renal artery, renal vein and splenic vein before and after cardiopulmonary bypass. Portal pulsatility index, renal resistive index, and respiratory variations in peak aortic blood flow velocity and diameter of inferior vena cava are measured.

Inclusion Criteria:

• All pediatric patients undergoing cardiac surgery

Exclusion Criteria:

• Applying extracorporeal membrane oxygenator prior to surgery
• Trouble applying echocardiography
