60年代末纤维光学支气管镜(FOB)进入临床,给诊断和治疗许多肺部疾病带来革命性的变化。后来,当发现在各种类型人群中使用FOB都是安全可靠的,临床医生就开始把FOB做为亚段支气管肺泡灌洗(BAL)的一种方式。尽管早期报告提示要警惕发生低氧血症,心律失常和低血压。但研究发现单独使用支气管镜对许多危重的插管病人是安全的。然而最近两份研究提示ARDS及其他弥漫性肺疾病患者可能发生这些合并症的危险性会增加。 BAL是对肺泡微环境取样的一个极有价值的办
Fiberoptic bronchoscopy (FOB) enters the clinic in the late 1960s, revolutionizing the diagnosis and treatment of many lung diseases. Later, when it was found safe to use FOBs in all types of people, clinicians began using FOB as a method of sub-bronchoalveolar lavage (BAL). Although early reports suggest vigilance on hypoxemia, arrhythmia and hypotension. However, the study found that bronchoscopy alone was safe for many critically ill intubated patients. However, two recent studies suggest that patients with ARDS and other diffuse lung diseases may be at increased risk for these comorbidities. BAL is an extremely valuable sample of the alveolar microenvironment
