电子支气管镜应用于临床以来,以其相对安全、可靠、创伤小、亮度强、视野广阔而倍受亲睐,并已成为呼吸系统疾病临床诊断和治疗的重要手段之一[1],其临床适应证已越来越广泛。但是此项检查为有创性检查,对操作者和患者的要求相对比较高,有一定的风险性,但死亡率还是相对较低。有文献报道,支气管镜检查并发症的发生率约0.3%,较严重的并发症的发生率为0.1%,病死率约0.01%[2]。我院自2009年开始应用电 Since its application in clinical practice, electronic bronchoscopy has become one of the most important means of clinical diagnosis and treatment of respiratory diseases due to its relatively safe, reliable, less trauma, strong brightness and broad field of vision [1], and its clinical Indications have become more and more widespread. However, this examination is an invasive examination, with relatively high demands on operators and patients, and a certain degree of risk, but the mortality rate is still relatively low. It has been reported in the literature that the incidence of complications of bronchoscopy is about 0.3%, the incidence of more serious complications is 0.1% and the case fatality rate is about 0.01% [2]. Our hospital since 2009, the application of electricity
