42例患者,外伤后两周到7年发生脑脊液鼻漏,其中10例为间歇性,间歇期数周到2年。漏液由少许到每昼夜300ml左右不等,与外伤程度无关。为了确定鼻漏为脑脊液,曾对26例患者应用了“快速诊断法”,即借指示剂“葡萄糖试验”确定漏液中的糖含量,后者在脑脊液中比鼻分泌物中高。对8例患者经椎管内注入80～100ml生理盐水及0.5m1 5%萤光素钠或酸性靛蓝暂时增加脑脊液压,借此确定是否存在脑脊液鼻漏。为了确定漏道的位置,作者在表麻下分别向上、中、下鼻道放置用不同色线缚着的纱条,然后于椎管内注入0.5ml 5%萤光素钠,20分钟后抽出纱条观察其着色情况。同时可借三个鼻道放置浸有指示剂的纸条观察着色情况。漏液太少 Forty-two patients developed cerebrospinal fluid rhinorrhea two weeks to seven years after trauma, of which 10 were intermittent and intermittent for weeks to 2 years. Leakage from a little to 300ml per day and night range, has nothing to do with the degree of trauma. In order to determine the presence of rhinorrhea as cerebrospinal fluid, “rapid diagnostic” was used in 26 patients to determine the amount of sugar in the leak by means of the “glucose test” indicator, which is higher in cerebrospinal fluid than in nasal secretions. Eight patients were temporarily intubated with 80-100 ml of saline and 0.5 ml of 5% sodium fluorescein or acid indigo to increase cerebrospinal fluid pressure temporarily to determine whether CSF leakage was present. In order to determine the position of the drain, the authors placed gauze tied with different colored threads to the upper, middle and lower nasal passages under the table and then injected 0.5 ml of 5% sodium luciferin into the spinal canal. After 20 minutes, Sliver observation of its coloring. At the same time can be placed by three nasal gauze soaked with indicator to observe the coloring. Leakage too little
