During a period of three years, 256 diagnostic bronchoscopies were done with flexible fiberoptic bronchoscopes at a Veterans Administration hospital. In all of these procedures, topical cocaine hydrochloride anesthesia was used, and it proved satisfactory and free of any undesirable side effects. The peroral route using an endotracheal tube is preferred for flexible bronchofiberscopy. Fluoroscopic guidance is essential in examining peripheral lung lesions. A 70 percent positive yield was obtained for patients with peripheral carcinoma of the lung as contrasted to a 47 percent yield when the tissue specimens were obtained blindly.
在三年时间里，一家退伍军人管理局医院使用可弯曲纤维支气管镜进行了256例诊断性支气管镜检查。在所有这些操作中，均使用了局部盐酸可卡因麻醉，结果证明效果令人满意且无任何不良副作用。对于可弯曲纤维支气管镜检查，经口插入气管导管的途径更为可取。在检查周围肺部病变时，荧光镜引导至关重要。与盲目获取组织标本时47%的阳性率相比，周围型肺癌患者的阳性率达到了70%。
