Abstract:
Objective? ? To? evaluate? the? protective? effect? and? curative? effect? of? early? treatment? with?extracorporeal?membrane?oxygenation?(ECMO)?in?severe?patients?with?acute?respiratory?distress?syndrome?(ARDS)?caused?by?acute?phosgene?poisoning.? Methods? The?course?of?treatment?of?4?cases?of?ARDS?caused?by?acute?phosgene?poisoning?admitted?to?intensive?care?unit?(ICU)?of?Jiangxi?Provincial?People's?Hospital?in?April?2018?was?retrospectively?analyzed.?The?treatment?parameters?in?patients?before?and?after?the?ECMO?treatment?at?1,?3,?7?days?were?collected,?including?pH?of?the?arterial?blood,?arterial?partial?pressure?of?carbon?dioxide?(PaCO2),?arterial?partial?pressure?of?oxygen?(PaO2),?blood?lactic?acid?(Lac)?and?systemic?vascular?resistance?index?(SVRI),?cardiac?index?(CI),?extravascular?lung?water?index?(ELWI),?plateau?pressure?(Pplat),?positive?end-expiratory?pressure?(PEEP),?driving?pressure?(ΔP),?and?acute?physiology?and?chronic?health?evaluation?Ⅱ?(APACHE?Ⅱ),?the?length?of?ICU?stay,?the?treatment?duration?of?ECMO?and?the?duration?of?mechanical?ventilation.?
