Abstract:
PURPOSE: It has been reported that the Pulse Contour Cardiac Output (PiCCO) is very useful mainly in the field of intensive care and treatment to grasp the pathophysiological conditions of pulmonary edema because of its capability of obtaining data such as Pulmonary Vascular Permeability Index (PVPI) and Extra Vascular Lung Water (EVLW). Furthermore, a high degree of usability of various markers has been reported for better understanding of the pathological conditions in cases with septicemia. MATERIALS AND METHODS: The correlation between the cardiorespiratory status based upon the PiCCO monitor (EVLW and PVPI) and inflammatory markers including C reactive protein, procalcitonin (PC), and Endotoxin Activity Assay (EAA) were evaluated in 11 severe cases that required treatment with a respirator in an intensive care unit. RESULTS: The EAA values were significantly higher in patients with abnormal EVLW at 0.46+/-0.20 compared to the normal EVLW group at 0.21+/-0.19 (p=0.0064). In a similar fashion, patients with abnormal PVPI values tended to have higher PC levels at 18.9+/-21.8 compared to normal PVPI cases at 2.4+/-2.2 (p=0.0676). On the other hand, PVPI was significantly higher in the abnormal EAA group at 3.55+/-0.48 in comparison with the normal EAA group at 1.99+/-0.68 (p=0.0029). The abnormal EAA group tended to have higher PVPI values than the normal EAA group. CONCLUSION: The EAA is a measurement method designed to estimate the activity of endotoxins in the whole blood. Our results suggest that the EAA value, which had the greatest correlation with lung disorders diagnosed by the PiCCO monitoring, reflects inflammatory reactions predominantly in the lungs.
