Focused TTE for Hemodynamic Instable High Risk Patients

N/ACompletedNCT01811914

Philipps University Marburg50 enrolled

Overview

Focused transthoracic echocardiography (TTE) is a technique, which allows quick and non-invasive diagnosis and monitoring in hemodynamic instable patients. There are preliminary data supporting the hypothesis that TTE is feasible in the operating theatre. The purpose of this study is to test the hypothesis that intraoperative focused TTE has an impact on high risk patients´ management when it is added to standard extended monitoring practices in hemodynamic instabilities.

Focused TTE is en emerging matter in anesthesia, intensive care and emergency medicine. The value of intraoperative TTE is unclear. There are preliminary data that it is feasible For intraoperative transesophageal echocardiography (TEE) an impact on cardiac and non-cardiac surgery patients´ management has been shown. Purpose of this study is to evaluate the application of focused TTE in patients with increased perioperative risk undergoing moderate to high risk surgery who become hemodynamic instable during anesthesia in the operating theatre. When hemodynamic instability under anesthesia occurs focused TTE is conducted and the obtained diagnostic information are used for further patient management. Any change in management or therapy will be recorded.
