近有报道用特细穿刺针(23～25号)作肺抽吸活检的诊断率与用粗针相似而并发症减少。本文总结1981～1984年间以特细穿刺针对282例进行肺抽吸活检的经验,并对49例的细胞学及组织学诊断结果进行对比分析.方法及结果以1％利多卡因局麻,在 X 线引导下进行穿刺.针刺入病变部位后,接20ml 注射器,连续负压抽吸,并将针旋转进退数次,吸出物作巴氏 Recently, it has been reported that the diagnostic rate of ultra-small needles (Nos. 23-25) for pulmonary biopsy is similar to that of a rough needle and the complications are reduced. This article summarizes the experience of 282 cases of lung biopsy performed with special puncture from 1981 to 1984, and compares the cytologic and histological diagnoses of 49 cases. The method and results were performed with 1% lidocaine local anesthesia. The puncture was performed under the guidance of X-rays. After the needle was inserted into the lesion, a 20-ml syringe was connected, and continuous suction was performed. The needle was rotated and advanced several times. The aspirate was used as a pasteurizer.
