Abstract:
ObjectiveTo guide fluid management and evaluate the clinical index through monitoring extravascular lung water index(EVLWI) of patients with pulmonary contusion.MethodsThirtyone severe chest trauma patients with pulmonary contusion were selected,performed with central venous catheterization or femoral artery catheterization,and connected to pulse index continuous cardiac output (PICCO).EVLWI after pulmonary contusion were measured by using thermal dilution.The intake and output of patients were recorded in detail,fluid intake was controlled,furosemide was prescribed,and the changes and correlations of oxygenation index,EVLWI and liquid balance difference at different time points were evaluated.ResultsEVLWI after pulmonary contusion at 1st to 7th d after hospitalization was respectively (9.25 ±0.71),(8.98 ±0.61),(8.61 ±0.59),(7.75±0.53),(6.64 ±0.49),(6.22±0.36),(5.59 ±0.39) ml/kg.Comparing with 1st d after hospitalization,EVLWI declined from 3rd d (P ＜ 0.05).Oxygenation index at Ist to 7th d after hospitallzation was respectively( 145.76±23.61 ),( 144.19±20.24),( 146.67±19.25 ),(159.33±15.42),(177.38±14.25),(199.33±19.04),(213.71±18.51) mm Hg(1 mm Hg =0.133 kPa).Comparing with 1st d,oxygenation index from 4th to 7th d had significant difference (P ＜ 0.05 ).The fluid volume at 1st d to 7th d were all negative balance,that of 3rd d to 6th d had significant difference comparing with 1st d [(-431.43±121.17),(-601.43±127.09),(-629.52±140.69),(-320.01 ±93.71) ml vs.(-213.81±63.91 ) ml](P ＜ 0.05 ).Oxygenation index and EVLWI had negative correlation(r =-0.824,P＜0.01).Liquid balance difference and the changes of oxygenation index and EVLWI had no correlation.ConclusionEVLWI effectively monitoring after pulmonary contusion can not only evaluate the changes of pulmonary vascular permeability of patients with pulmonary contusion,but also have important significance to guide fluid management.
