摘　　要：目的对比分析双腔支气管导管(DLT)和支气管封堵器(BB)在单肺通气时对呼气末二氧化碳分压(PetCO2)和动脉血二氧化碳分压(PaCO2)的影响。方法 30例择期进行胸科手术的患者随机分为DLT组和BB组,每组15例。两组患者在麻醉诱导后进行BB或DLT置入,记录两组进行单肺通气后的PetCO2和PaCO2值。结果进行单肺通气时,DLT组的PetCO2值高于BB组,PaCO2值低于BB组,PetCO2与PaCO2相关性优于BB组。结论与使用BB相比,使用DLT进行单肺通气更有利于CO2的排出。Objective To assess the effect of double-lumen-tube （DLT） and bronchial blocker for one-lung ventilation on partial pressure of end-tidal carbon dioxide （ PetCO2 ） and arterial partial pressure of carbon dioxide （ PaCO2 ）. Methods Thirty patiems were randomly assigned to DLT group （ n = 15 ） and BB group （ n = 15）. After anesthesia in- duction, DLT or BB was intubated into the trachea. After one-lung ventilation, the values of PetCO2 and PaCO2 were recorded and analyzed. Results Compared with BB group, the PetCO2 value was higher, the PaCO2 value was lower, and the correlation between PetCO2 and PaCO2 was better in DLT group. Conclusion Compared with BB, DLT wasbetter at exhalation of CO2.
