Hemodynamic Survey Cardiac Surgical Scenarios

The purpose of this study is to find out the Lidco Rapid ( monitoring tool gives cardiac output) is as equivalent in determining the hemodynamic assessment in cardiac surgical scenarios as the most often used pulmonary artery catheter, which is much more invasive than the Lidco Rapid. This will be accomplished through online surveys which have different cardiac surgery scenarios and will be distributed to cardiac fellowship trained anesthesiologists. The online based survey will include a specific scenario and details on the scenario represented in image format and a brief description of the patient to aid with their analysis of the situation.

About this study

Data from PA catheter such as PA pressure, pulmonary wedge pressure and cardiac output has been widely used in the various clinical situations warranting advance hemodynamic monitoring. It is considered as gold standard but unfortunately there is always risk associated with PA catheter and time lag between the clinical events and interpretation. Lidco Rapid is one of the non-invasive hemodynamic tools to measure various parameters. It is widely used in the intensive care set up for goal directed therapy but unfortunately there is not enough data to show whether it is useful in various peri-operative clinical conditions. In the online based survey, responses from the participants are recorded in the nominal scale ( 1 to 5 where 3 represents near normal). This survey will help to determine whether Investigators can replace the Lidco in any clinical situation warranting advance hemodynamic monitoring.

No previous study was done to specifically find out the hemodynamic component that differs between these tools intraoperatively in varying hemodynamic conditions during cardiac surgery although there were few studies compared the trend in the cardiac output with difference in opinion on their accuracy.
