纤维光束气管镜的检查在临床上对诊断、治疗、外科手术方案均有一定助益,而局部麻醉的效果对临床检查有一定影响,一个良好局部麻醉应具备以下几个条件:麻醉时1.无痛苦,效果良好。2.操作简便而且安全。3.付作用小。我们根据喷雾器的原理加以革新改进,成功应用于支气管内麻醉,虽然支气管长达60公分,而且几经弯曲,即使深至第三四级支气管内,最后药液在管口仍呈密细雾状喷出。自79 The inspection of fiber beam bronchoscope is helpful to diagnosis, treatment and surgical procedures in clinical practice. The effect of local anaesthesia has a certain influence on clinical examination. A good local anaesthesia should have the following conditions: 1. No pain, good results. 2. Easy to operate and safe. 3. Pay a small role. According to the principle of the nebulizer, we have been innovatively improved and successfully applied to bronchial anesthesia. Although the bronchus is up to 60 cm long and has been bent, even if it reaches to the third or fourth grade bronchus, the final solution is still sprayed at the nozzle. Out. Since 79
