ABSTRACT
Objective To analyze the correlations between acute respiratory distress syndrome ( ARDS) and extravascular lung water(EVLW),tumor necrosis factor alpha (TNF-α),E-selectin,vasostatin-2.To discuss the value of EVLW, TNF-α, E-selectin and vasostatin-2 in evaluating the severity of ARDS and prognosis of this disease . Methods There are thirty-six patients with ARDS were selected .According to the level of EVLWI shown by pulse indicator continuous cardiac output ( PiCCO) monitor,they were divided into the two groups:EVLWI≥14mL/kg group (n=18) and EVLWI0.05).EVLWI had positive correlation with PVPI,TNF-αand E-selectin (r=0.605,0.649, 0.549,all P0.05).Conclusion There were significant correla-tions between EVLWI and TNF-α,E-selectin in patients with ARDS.The levels of EVLWI,TNF-α,E-selectin were higher,and the mortality rate was higher,the the stay time in ICU was longer.The levels of EVLWI,TNF-αand E-selectin can provide a good reference value to the judgement of the severity of disease and prognosis in patients with ARDS.The level of vasostatin-2 had no correlation with EVLWI .
