As of January 3, 2009, more than 208 countries and overseas territories or communities have reported laboratoryconfirmed cases of pandemic influenza H1N1 2009, including at least 12 799 death cases.1 Critical cases developed severe acute respiratory distress syndrome （ARDS） rapidly, which was refractory to conventional mechanical ventilation and rescue therapies.展开更多
目的探讨阵发性房颤对经肺热稀释法所监测参数准确性的影响。方法观察12例急诊EICU阵发性房颤患者在房颤前及房颤过程中所监测的血流动力学参数(心率、平均动脉压、心脏指数、系统血管阻力指数、胸腔内血容量指数、血管外肺水指数、肺...目的探讨阵发性房颤对经肺热稀释法所监测参数准确性的影响。方法观察12例急诊EICU阵发性房颤患者在房颤前及房颤过程中所监测的血流动力学参数(心率、平均动脉压、心脏指数、系统血管阻力指数、胸腔内血容量指数、血管外肺水指数、肺部超声测定的B线数目)的变化。结果患者发生房颤时,心率较基线状态下明显上升[(123.3±20.0)次/min比(98.9±12.3)次/min,P=0.006];平均动脉压[(86.9±10.2)mm Hg(1 mm Hg=0.133 k Pa)比(93.0±12.5)mm Hg,P=0.058]、心脏指数[(2.82±0.62)L/(min·m2)比(3.31±1.02)L/(min·m2),P=0.058]及系统血管阻力指数[(2 254±947)dyn·s·cm-5·m2比(2 302±828)dyn·s·cm-5·m2,P=0.351]无变化;胸腔内血容量指数明显升高[(1 333±90)ml/m2比(937±111)ml/m2,P<0.001];血管外肺水指数明显升高[(16.1±1.1)ml/kg比(6.5±1.9)ml/kg,P<0.001];肺部超声测定的B线数目无变化(10.0±4.2比9.4±4.4,P=0.180)。结论发生房颤后经肺热稀释法会高估胸腔内血容量指数和血管外肺水指数,在临床工作中需要结合实际情况及其他监测手段如查体、肺超声检查等,进行综合判断及决策。展开更多
