Hemodynamic monitoring is important for diagnosis and therapy of critically ill patients. Thermodilution is now the gold standard method; however, it cannot be used routinely since it is very invasive. We investigated the agreement between the cardiac index (CI) obtained by mini-invasive monitor MostCare, based on the pressure recording analytical method (PRAM), and by PiCCO thermodilution in hemodynamic unstable patients.
We performed a prospective clinical study at our university hospital ICU. Twenty adult patients with hemodynamic instability were enrolled. All patients were sedated and mechanically ventilated with intermittent positive pressure ventilation. The MostCare and PiCCO systems were connected to each patient by a catheter inserted into the femoral artery. For each patient three measurements of CI were simultaneously carried out and the mean was considered for statistical analysis.
This study showed a sufficient agreement between the two techniques. MostCare could be a useful first-level monitoring system, particularly in the first phase of critically ill patients' care or when more invasive systems are not advisable.
