呼气末CO2和其它监测指标的联合应用与麻醉管理

目的介绍呼气末ＣＯ２（ＥＴＣＯ２）和其它监测指标的联合应用在麻醉管理中的意义及作用。方法应用心电图（ＥＣＧ）、有创血压、ＣＯ２曲线图和脉搏容积图同步监测的方法,对２２名行全麻手术的患者进行了监测。对１０名在硬膜外或颈丛阻滞下手术的患者进行了ＥＴＣＯ２监测。结果在全身麻醉中,同步监测ＥＴＣＯ２、ＣＯ２曲线图、脉搏容积图、血压和心电图,可对麻醉深度、通气状态及肌松程度作出整体评估。ＥＴ－ＣＯ２还可对自主呼吸状态下呼吸功能的评估提供客观标准。结论ＥＴＣＯ２和其它监测指标的联合应用可提高麻醉的安全性及麻醉管理的精确性。

Simultaneously monitoring end tidal CO2 and other parameters versus anesthesia management

OBJECTIVE: To investigate the significance of end tidal CO2(ETCO2) combined with other techniques in anesthesia management. METHODS: Twenty two patients undergoing general anesthesia were monitored with electromyocardiogram (ECG), invasive arterial blood pressure (IABP), plethysmogram and capnography simultaneously. Ten patients undergoing epidural anesthesia and cervical plexus block were monitored with ETCO2. RESULTS: During general anesthesia the depth of general anesthesia, status of ventilation and the degree of muscle relaxation could be grossly evaluated by simultaneously monitoring ETCO2, capnography, plethysmogram, ECG and IABP. ETCO2 could also provide an objective standard for the assessment of respiratory function during spontaneous ventilation. CONCLUSIONS: ETCO2 combined with other monitoring techniques can increase the safety of anesthesia and the accuracy of anesthesia management.
