The objective is to compare two methods of cardiac output measurement in children: the new non-invasive method called esCCO™ (by Nihon Kohden, Tokyo, Japan) and the established more invasive method transesophageal echocardiography (TEE). esCCO™ is a completely non-invasive method that could provide a cardiac output measurement in a large range of pediatric patients because of an extremely low risk benefit balance.
Cardiac output monitoring has been technically challenging in pediatric patients. Available methods for measuring cardiac output in children are either inaccurate or highly invasive or limited to a small number of patients. So far esCCO™ has not been tested in the pediatric population but showed promising results when it was tested against the pulmonary artery catheter in adult patients undergoing heart surgery in previous Japanese studies.
Thus the validity of esCCO™ is now tested in pediatric patients scheduled for elective cardiac surgery. Transesophageal echocardiography has been chosen as reference method because it is performed routinely during pediatric cardiac surgery.
The algorithm for esCCO™ -measurement is integrated in an approved patient monitor that replaces the standard patient monitor during the measurement-period.
In the study protocol, events like esCCO™ -calibration time, catheter positioning time, ventilation settings, volume in- and output and drug administration, patients's data and diagnoses are logged. Vital parameters from the patient monitor including the esCCO™-cardiac output values are recorded every second in real time on a study laptop mounted on the same rack as the patient monitor but electrically separated from the other devices.
EsCCO™ measurements shall be compared to TEE cardiac output measurements at three given times: (1) before surgical intervention, (2) shortly after cardiopulmonary bypass and (3) after closure of the thorax.
A total of 50 patients shall be investigated in the study during a planned study time of approximately 6 months. The ethics committee of the University of Heidelberg gave their consent to the study (S-108/2012). For statistical analysis, a Bland-Altman-test for measurements with multiple values per patient, correlation graphics and a regression equation will be performed.
