[Invasive cardiovascular monitoring--four methods compared].
The impact of invasive hemodynamic monitoring on patient safety and outcome in perioperative medicine remains inadequately tested and unproven. The indications for the use of these tools should, therefore, be evaluated according to an individual risk-benefit analysis. The measurement of central venous oxygen saturation (ScvO2) is of little invasiveness as most high-risk patients are instrumented with central venous catheters, and ScvO2 has been shown to improve outcome in patients with septic shock. Transpulmonary thermodilution (e.g. PiCCO-system) delivers information not only on global cardiac function and intravascular volume status but also helps to define the pulmonary consequences of cardiovascular therapy. Transesophageal echocardiography (TEE) is a valuable tool in patients undergoing cardiac surgery and represents the beside-method of choice for rapid assessment of acute life-threatening cardiovascular instability. Apart from special indications, these tools tend to replace the pulmonary artery catheter (PAC) which has been shown to be of little value in various patient populations.
