目的：比较巴曲抗栓酶与尿激酶治疗突发性耳聋的疗效。方法：患突发性耳聋３２例（３７耳），男性２０例，女性１２例，年龄５１±ｓ１２ａ，给予巴曲抗栓酶，首次剂量１０～２０ＢＵ静脉滴注（静滴），以后隔日一次５ＢＵ。对照组３１例（３５耳），男性１７例，女性１４例，年龄４３±１４ａ，应用尿激酶６万Ｕ加右旋糖酐－４０，５００ｍＬ静滴，疗程均３ｗｋ。结果：２组总有效率分别为８４％和６１％（Ｐ＜０．０５），治疗组血液粘度亦显著降低。副作用轻微。结论：巴曲抗栓酶治疗突发性耳聋效果较满意。 Objective: To compare the efficacy of batroxobin and urokinase in the treatment of sudden deafness. Methods: There were 32 cases (37 ears) with sudden deafness, 20 males and 12 females, aged 51 ± s12a, given batroxobin, the first dose of 10 ~ 20BU intravenous drip (intravenous drip), every other day 5BU. Control group, 31 patients (35 ears), 17 males and 14 females, age 43 ± 14a, the application of urokinase 60,000 U plus dextran 40,500 mL intravenous infusion, the treatment of 3wk. Results: The total effective rates in two groups were 84% and 61%, respectively (P <0.05), and the blood viscosity of the treatment group was also significantly reduced. Slight side effects. Conclusion: Batroxobin is effective in treating sudden deafness.
