气管内给药,有几种药物是有效果的,如纳络酮、安定、利多卡因、肾上腺素和阿托品。Redding等提出气管内给药,可作为心跳停止病人的一条给药途径。在狗,用低氧导致心跳停止,然后气管内给予肾上腺素(1mg稀释于10ml),其恢复循环的效果与静脉或心内注射同样量肾上腺素的效果一样。 有时药物经呼吸道给予时,可经肺泡毛细血管膜而被吸收,但这种方法仅适用于极小颗粒或飞沫(直径在6～0.1μm或更小)。较大的颗粒飞沫则在气管、支气管树的粘膜就被吸收了。因为所有气管、
Intratracheal administration, there are several drugs are effective, such as naloxone, diazepam, lidocaine, epinephrine and atropine. Redding et al suggest that intratracheal administration may be used as a route of administration for patients with cardiac arrest. In dogs, heart beats are stopped with hypoxia, and then epinephrine is given intratracheally (1 mg diluted in 10 ml), the effect of which is the same as the intravenous or intracardiac injection of the same amount of epinephrine. Sometimes when the drug is given through the respiratory tract, it can be absorbed through the alveolar capillary membrane, but this method is only suitable for very small particles or droplets (6 to 0.1 μm in diameter or smaller). Larger droplets in the trachea, bronchial tree mucosa was absorbed. Because all trachea,
