The middle ear gas composition has been examined in 5 air-ventilated dogs under sodium thiopentone anesthesia. The gas samples were obtained by transtympanic puncture and analysed by gas chromatography. The following mean +/- S.D. gas composition was obtained: N2 83.2 +/- 5.0; O2 12.1 +/- 2.2; and CO2 4.7 +/- 0.7.
在硫喷妥钠麻醉下,对5只通气的犬的中耳气体成分进行了检测。通过鼓膜穿刺获取气体样本,并采用气相色谱法进行分析。得到以下平均±标准差的气体成分:氮气83.2±5.0;氧气12.1±2.2;二氧化碳4.7±0.7。
