【摘要】：正胃内容物反流或口咽部分泌物误吸是气道或肺部并发症的最常见原因,尽管气管内插管可以明显减少误吸的发生,但临床上仍会有少量误吸造成肺部并发症的实例。目前临床上通过气管内导管套囊充气达到一定的压力,来防止误吸的发生。套囊内压力过高会对气管造成损伤,但套囊压力过低则不能完全防止误吸。气管导管气囊内充入液体时,受压后容积几乎无变化,所以液体套囊在低压力时也能防止误
[Abstract]:The most common cause of airway or pulmonary complications is reflux of positive gastric contents or aspiration of oral and pharyngeal secretions. Although endotracheal intubation can significantly reduce the incidence of missuction, there are still a few cases of pulmonary complications caused by missuction. In order to prevent the occurrence of false aspiration, a certain pressure is reached through the inflation of intratracheal catheter sheath in clinic at present. Too high pressure in the capsule can cause injury to the trachea, but too low pressure of the capsule can not completely prevent aspiration by mistake. The volume of the trachea balloon is almost the same when it is filled with liquid, so the liquid capsule can also prevent the mistake when the pressure is low.
