1980年Bhargava氏介绍了鼻腔局部涂布15％硝酸银的方法治疗过敏性和血管运动性鼻炎,经我们略加改良操作如下:先于病人鼻腔喷以1％麻黄素液收缩鼻粘膜,然后再喷1％地卡因或放置1％地卡因棉片于鼻腔前部作表面麻醉,五分钟后取出棉片,将已浸有15％硝酸银液约1平方厘米大小的棉片贴附于鼻中隔 In 1980, Bhargava introduced nasal topical application of 15% silver nitrate for the treatment of allergic and vasomotor rhinitis. We slightly modified the procedure as follows: Nasal mucosa was contracted in patients with nasal spray with 1% ephedrine solution before Spray 1% dexamethasine or place 1% tetracaine cotton on the front of the nasal cavity for surface anesthesia, remove the cotton pad after 5 minutes, and soak a 15% silver nitrate solution about 1 square centimeter on the size of cotton attached to nasal septum
