可屈性纤维支气管镜检查(FFB)被广泛应用于各种肺部疾病的诊断和治疗,其并发症和病死率都很低,是一种比较安全的操作。FFB中的血流动力学变化已得到证实,平均动脉压、心率及心脏指数均增加。由于应用了利多卡因,严重心律失常的发生率较前降低,心律失常与最低血氧饱和度持续时间密切相关,而与年龄、性别或原有心肺疾患无关。FFB对于稳定性冠状动脉性心脏病(CAD)患者是安全的,这些患者心肌缺血和心律失常的发生率并不比正常人高。但是,一般认为近期急性心肌梗死
Flexible fiberoptic bronchoscopy (FFB) is widely used in the diagnosis and treatment of a variety of pulmonary diseases, its complications and mortality are very low, is a safer operation. The hemodynamic changes in FFB have been confirmed with an increase in mean arterial pressure, heart rate, and cardiac index. Due to the use of lidocaine, the incidence of severe arrhythmia was lower than before, and arrhythmia was closely related to the duration of the lowest oxygen saturation regardless of age, sex or previous cardiopulmonary disease. FFB is safe for patients with stable coronary artery disease (CAD), whose incidence of myocardial ischemia and arrhythmia is not higher than that of normal individuals. However, it is generally believed that the recent acute myocardial infarction
