摘要：
背景：电阻抗成像（EIT）技术在重症监护机械通气患者的持续监测中的应用逐渐增多。临床观察到胸腔积液患者异相阻抗变化增多。我们推测这种异相阻抗变化是胸腔积液患者的EIT典型表现，能够用于检测胸腔积液。Methods:Weconductedaprospectiveobservationalstudyinintensivecareunitpatientswithandwithoutpleuraleffusion.Inpatientswithpleuraleffusion,EITdatawererecordedbefore,during,andafterunilateraldrainageofpleuraleffusion.Inpatientswithnopleuraleffusion,EITdatawererecordedwithoutanyintervention.EITimageswereseparatedintofourquadrantsofequalsize.Weanalysedthesumofout-of-phaseimpedancechangesintheaffectedquadrantinpatientswithpleuraleffusionbefore,during,andafterdrainageand北京治疗白癜风得多少钱复方樟脑酊
