纤维支气管镜引导双腔支气管导管插管的临床观察

Clinical analysis of the intubating of double-lumen endobronchial tube with fiberobronchoscope

目的:观察纤维支气管镜对双腔支气管导管插管的引导作用及患者血气分析结果。方法:对30例开胸手术患者在纤维支气管镜引导下行双腔支气管导管插管。并在术前,双肺通气,单肺通气15min,单肺通气30min时取动脉血行血气分析。结果:30例患者血氧饱和度,血氧分压及二氧化碳分压值均在正常范围。结论:在纤维支气管镜引导下的双腔支气管导管插管位置正确,不影响患者气体交换。

Objective： To study the intubating of double-lumen endobroncbial tube with fiberobronchoscope and blood gas analysis. Methods： Thirty patients were intuhated of double-lumen endobronchial tube with fiberobronchoscope. Blood sample were taken from radial artery before anesthesia （T1）,both lungs were ventilated （T2） ,at 15,45 min of one-lung ventilation （T3-4） for blood gas analysis. Results： The number of oxygen saturation ,arterial blood oxygen partial pressure and arterial blood carbon dioxide partial pressure were normal in scope. Conclusion： The gas change will not be affected if the position of double-lumen endobronchial tube with fiberobronchoscope is right.
