Chest:体外CO₂清除装置对部分COPD患者有益

2014-02-25 佚名 不详

伴高碳酸血症的COPD患者常规应用机械通气治疗,但体外CO2清除装置治疗这种患者仍无系统性评价研究。针对这种情况,来自美国康涅狄格大学健康中心的Burki博士等人进行了一项试验性研究。作者发现体外CO2清除装置可用于治疗高碳酸血症性呼吸衰竭的COPD患者。 研究人员对30名高碳酸血症的COPD患者行试验性治疗,并确定了无创通气治疗患者(n=7)、无创通气治疗且无法脱机患者(n=2)和有创通气治疗

伴高碳酸血症的COPD患者常规应用机械通气治疗,但体外CO2清除装置治疗这种患者仍无系统性评价研究。针对这种情况,来自美国康涅狄格大学健康中心的Burki博士等人进行了一项试验性研究。作者发现体外CO2清除装置可用于治疗高碳酸血症性呼吸衰竭的COPD患者。

研究人员对30名高碳酸血症的COPD患者行试验性治疗,并确定了无创通气治疗患者(n=7)、无创通气治疗且无法脱机患者(n=2)和有创通气治疗且无法脱机患者(n=11)。体外CO2清除装置应用单腔静脉导管,对各组的血流量、动脉CO2分压(Pa CO2)及脱机情况进行比较。

结果显示,血流量及体外CO2清除装置的血流量稳定(430.5±73.7 mL/min;82.5±15.6 mL/min)。无创通气治疗患者均不需有创通气治疗,且PaCO2明显下降(78.9±16.8 mm Hg至65.9±11.5 mm Hg);无创通气治疗且无法脱机患者及有创通气治疗且无法脱机患者均可脱机。

该研究发现,体外CO2清除装置以单腔,低流量为特点,可降低高碳酸血症性呼吸衰竭的COPD患者的血CO2浓度。该装置可作为治疗高碳酸血症性呼吸衰竭的COPD患者的一种辅助治疗方法。
