FloTrac/Vigileo系统在单肺通气心输出量监测中应用的探讨

Investigation of FloTrac/Vigileo in monitoring cardiac output during one lung ventilation

目的观察FloTrac／Vigileo系统在单肺通气心输出量（CO）监测中的应用效果。方法择期单肺通气手术患者17例，ASAⅡ或Ⅲ级，使用FloTrac／Vigileo系统观察CO变化，记录诱导后（T0）、单肺通气5min（T1）、10min（T2）、30min（Ts）以及双腔管双肺通气时（T4）、关胸时（T5）的HR、MAP、心脏指数（CI）、每搏量变异度（SVV）和气道峰压（Pmax）。结果与T0时比较，T1、T5时CI明显增加（P〈0．05）；T1～T5时SVV，均明显下降（P〈O．05）；T1～T3时Pmax显著增加（P〈0．05）。结论FloTrac／Vigileo系统能快速、持续地监测单肺通气时CO的变化。

Objective To investigate the efficacy of FloTrac/Vigileo in monitoring cardiac output during one lung ventilation. Methods Seventeen ASA Ⅱ or Ⅲ patients requiring one lung ventilation （OLV） were enrolled in the study. Cardiac index （CI） and stroke volume variation （SW） were recorded using FloTrac/Vigileo after anesthesia induction （To）, 5 rain after （T1）, 10 rain after （T2）, 30 min after （T3） OLV, during double-lumen-endobronchial-tube ventilation （T4） and at closing thorax （T5）. HR, MAP and airway pressure were also recorded at these time points. Results Compared with To, CI increased significantly at T1 and T5 （ P 〈 0.05） ; SVV decreased significantly from T1 to T5 （P〈0. 05） ; and Pmax increased significantly from T1 to T3 （P〈0.05）. Conclusion FloTrac/Vigileo can be used to rapidly and continuously monitor cardiac output during one lung ventilation continuously.
