摘要 目的探讨雾化吸入伊洛前列素联合一氧化氮评价中重度肺动脉高压急性血管反应试验的降压效应和利用无创超声心动图监测的可行性。方法20例中重度肺动脉高压心脏病患者,先雾化吸入伊洛前列素5μg,20min后吸入一氧化氮15min。用无创技术和体表超声心动法分别测量安静状态下、雾化吸入伊洛前列素后即刻、吸入NO后即刻3个时间点的系统平均血压(MBP)、心率(HR)、肺动脉收缩压(sPAP)、肺动脉舒张压(dPAP)、平均肺动脉压(mPAP)、右心排血量(CO_R)、左心排血量(CO_L)、肺血管总阻力(PVR_总)、脉搏血氧饱和度(SpO_2)、左心室舒张内径(LVED)、左心室收缩内径(LVSD)、左心房内径(LAD)、射血分数(EF)。结果雾化吸入伊洛前列素和一氧化氮后MBP略有降低,但无统计学意义。雾化吸入伊洛前列素后,sPAP、dPAP、mPAP、PVR较基础值降低(均P<0.01),吸入NO后sPAP、dPAP、mPAP、PVR有进一步降低趋势,与基础值相比有统计学意义(均P<0.01),与吸入伊洛前列素后相比差异无统计学意义。其他测量指标的差异无统计学意义。结论雾化吸入伊洛前列素5μg和吸入一氧化氮可使有反应的肺血管扩张,用于肺血管反应性试验是安全有效的。用体表超声心动图技术监测肺血管反应性试验无创、可行且便利。
