A new method of measuring cardiac output by transesophageal echocardiography

JRCT ID: jRCT1012230036

Registered date:30/08/2023

Basic Information

• Recruitment status: Recruiting
• Health condition(s) or Problem(s) studied: cardiac surgery
• Date of first enrollment: 30/08/2023
• Target sample size: 55
• Study type: Observational

Outcome(s)

• Primary Outcome: Concordance rate between cardiac output measured by new measurement method using transesophageal echocardiography and cardiac output measured by pulmonary artery catheterization
• Secondary Outcome: Correlation between cardiac output measured by new measurement method using transesophageal echocardiography and cardiac output measured by pulmonary artery catheterization. Association between cardiac output or cardiac power output and postoperative complications (death, myocardial infarction, cerebral infarction, non-occlusive mesenteric ischemia, acute kidney injury) and surrogate markers (lactic acid level, mixed venous oxygen saturation).
