Abstract:
Objective To evaluate the clinical value of pulse-indicated continuous cardiac output (PiCCO) in elderly patients with severe pneumonia and spetic shock.
Methods Treat 46 elderly patients with severe pneumonia and respiratory failure with Extravascular Lung Water Index (ELWI) or conventional central venous pressure (CVP) and radiographic exam to monitor fluid management. Comparison between two groups include 24 h, 48 h and 72-h Acute Physiology and Chronic Health Evaluation(APACHE) Ⅱ score, oxygenation index, blood lactate and mixed venous oxygen saturation (ScVO2). Fluid intake and output, duration of mechanical ventilation, ICU stay and 28-day mortality were also observed.
Results Seventy-two h-APACHE Ⅱ score was significantly lower in PiCCO group than CVP group (t=26.45, P<0.05). 48 h, 72 h-oxygenation index and ScVO2 in ELWI group were significantly higher than those in CVP group (t=4.16、15.43, P<0.05), while the 72 h-blood lactate was significantly lower in ELWI group than that in CVP group (t=16.22, P<0.05). The net liquid income were significantly reduced in ELWI group than that in CVP group (t=18.42、25.64、3.32、11.82, P<0.05). Compared with CVP group, duration of mechanical ventilation and ICU stay were significantly reduced in ELWI group (t=18.55、22.12, P<0.05). Compared with CVP group, 28-day mortality in PiCCO-monitoring patients decreased, but no significant difference was found (χ2=0.55, P>0.05).
Conclusion Extravascular lung water for fluid management in elderly patients with severe pneumonia and respiratory failure can significantly reduce the total fluid intake, improve patient oxygenation index, reduce ventilating time, shorten ICU length of stay and reduce mortality.
