摘要 利用FloTrac/Vigileo监测系统研究消化内镜治疗中二氧化碳注射对全身麻醉机械通气患者循环功能的影响.择期行消化内镜治疗术患者30例,ASA Ⅰ级或Ⅱ级,年龄55~60岁,体质量55~76 kg.术前排除心肺疾患患者.所有患者采用相同的全身麻醉方法:静脉快速诱导气管插管成功后,以丙泊酚、瑞芬太尼持续泵入,间断推注肌松药,维持麻醉深度,采用脑电双频谱监测仪指导并维持患者的BIS值在40~ 60,使其麻醉深度保持一定范围;行左侧桡动脉穿刺置管,连接FloTrac传感器和Vigileo监测仪连续监测血压(SBP、DBP、MAP)、心排出量(CO)、每搏输出量(SV)、每搏输出量变异度(SW);行右侧颈内静脉穿刺置管监测中心静脉压(CVP).分别在麻醉操作完成后5 min和二氧化碳注射后5、1 0、1 5min记录以上数据.并计算出体循环外周阻力(SVR)的数值.二氧化碳注射后,患者CVP升高(P<0.05),SW升高(P<0.05),心率增快(P<0.05),SV降低(P<0.05),CO增加(P<0.05),SVR增加(P<0.05),血压升高(P<0.05).消化内镜治疗中二氧化碳注射对全身麻醉机械通气患者的血流动力学会产生显著地改变.
