The purpose of this study was to rationalize the choice of injector and bronchoscope sizes during bronchoscopy under general anesthesia using the Sanders attachment technique. Arterial Po2 and Pco2, FIo2, and peak inspiratory pressure at the tip of the bronchoscope were plotted against the ratio (RI/B) of the internal diameters of the injector and the bronchoscope in seven dogs undergoing bronchoscopy under general anesthesia. Peak inspiratory pressure, FIo2, and PaO2, increased, and PaCO2 decreased with an increase in RI/B. A working table is proposed to predict the optimal RI/B.
本研究的目的是在全身麻醉下使用桑德斯附件技术进行支气管镜检查时，使注射器和支气管镜尺寸的选择合理化。在七只接受全身麻醉下支气管镜检查的犬中，将动脉血氧分压（Po2）和二氧化碳分压（Pco2）、吸入氧分数（FIo2）以及支气管镜尖端的吸气峰压与注射器和支气管镜内径的比值（RI/B）进行绘图。随着RI/B的增加，吸气峰压、FIo2和动脉血氧分压（PaO2）升高，而动脉血二氧化碳分压（PaCO2）降低。提出了一个工作表来预测最佳RI/B。
