Comparison of pulmonary artery and aortic transpulmonary thermodilution for monitoring of cardiac output in patients with severe heart failure: validation of a novel method.

摘要: Objective: Hemodynamic monitoring with the pulmonary artery catheter is frequently used in management of severe heart failure. For measurement cardiac output (CO), transpulmonary thermodilution (TPTD) has recently been adopted into clinical practice as an alternative to thermodilution. However, no data have published on comparability two methods for patients severely reduced left ventricular function. Our objective was evaluate correlation between these CO determination dysfunction. Design: Prospective observational study. Setting: Cardiological intermediate care unit and medical intensive a university hospital. Patients: Twenty-nine ejection fraction <35% symptoms failure (New York Heart Association class III-IV). Intervention: None. Measurements Main Results: The intermittent were compared by simultaneously recording results TPTD after injection cold saline bolus. performed when clinically necessary. A total 325 pairs analyzed. Mean both 4.4 L/min bias 0.45 (2 so 1.20 L/min), resulting percentage error 27.3%. Conclusion: In impaired function, provides valid results.
