[Continuous stroke volume monitoring as "hemodynamic online monitoring" in polytrauma intensive care patients: technically possible--clinically necessary?].
OBJECTIVE
Is the measurement of continuous cardiac output useful for the management of polytrauma patients?


METHODS
In a prospective non randomized study (ethic commission file 43/96) we evaluated the diagnostic and therapeutic impact of the CCO (continuous cardiac output measurement) for polytrauma patients on the ICU. The Baxter Vigilance System was used for measuring the continuous cardiac output. The CCO values were controlled once a day by the conventional "cold" thermodilution technique.


RESULTS
All values are given as mean +/- standard deviation. The Patients were scored on the first day for ISS (injury severity score) (47 +/- 17) and APACHE II (15 +/- 5). The CCO was used no later than 12 hours after the initial treatment in 20 polytrauma patients. As clinical outcome parameters were chosen: days on ventilation (23 +/- 23 days), days on the ICU (31 +/- 26 days) and mortality (20%). The treating ICU physicians were asked in a standardized questionnaire, whether or not there was an impact of the CCO measurement on their therapy. Seven different surgeons were working with the system.


CONCLUSIONS
The unique opinion was that the CCO device had an impact on their decision making in the fluid and drug management of the study patients. Our first experience, however, suggests that this device may become an important improvement in the management of haemodynamics in the early trauma phases. Before a wide-spread application of this method on the ICU an evidence based prospective randomized trial should be performed.
