目的：观察复方双氢麦角汀对无器质性病变的咽异感症病人的疗效。方法：咽异感症病人１６２例，随机分为２组，复方双氢麦角汀治疗组８２例（男性２５例，女性５７例；年龄４２±ｓ８ａ），口服复方双氢麦角汀２．５ｍｇ，ｂｉｄ，治疗２ｗｋ；对照组８０例（男性２３例，女性５７例；年龄４３±８ａ），口服谷维素、维生素Ｂ１各２０ｍｇ，ｔｉｄ，并口服地西洋２．５ｍｇ，ｑｎ，治疗２ｗｋ。并进行血液流变学检测。结果：复方双氢麦角汀组显效５０例，有效２６例；对照组显效３１例，有效３３例。经Ｒｉｄｉｔ分析，复方双氢麦角汀疗效优于对照组（Ｐ＜０．０５）。血液流变学检测结果，复方双氢麦角汀有降低咽异感症病人血液粘度作用（Ｐ＜０．０１）。结论：复方双氢麦角汀对治疗无器质性病变的咽异感症有效。
Objective: To observe the effect of compound dihydroergotine on patients with pharyngeal dysarthria without organic diseases. Methods: A total of 162 patients with pharyngeal dysarthria were randomly divided into two groups: 82 cases (25 males, 57 females; age 42 ± s8a), oral dihydroergocristine 2.5 mg bid 2wk; control group of 80 patients (23 males, 57 females; age 43 ± 8a), oral oryzanol, vitamin B1 20mg, tid and oral 2.5mg, qn, treatment 2wk. Hemorheology tests were performed. Results: The compound dihydroergotropin group markedly effective in 50 cases, effective in 26 cases; control group markedly effective in 31 cases, effective in 33 cases. Ridit analysis showed that compound dihydroergiferin was better than the control group (P <0.05). Blood rheology test results, compound dihydroergoline reduce pharyngeal dysarthrosis in patients with blood viscosity (P <0.01). Conclusion: The compound dihydroergoline is effective in treating pharyngitis with no organic disease.
