用思密达治疗３０例婴幼儿秋冬季腹泻并与用小诺霉素或病毒唑治疗作对照组，结果治疗组３０例，显效１７例（５６．７％），有效９例（３０％），无效４例（１３．３％），总有效率为８６．７％；入院后平均止泻天数为２．４７±１．０７天。对照组２０例，显效３例（１５％），有效７例（３５％），无效１０例（５０％），总有效率５０％；入院后平均止泻天数为３．７０±１．２２天。两组总有效率经统计学处理差异有高度显著性，＃ＦＫＰ＜０．００５，说明使用思密达对缩短腹泻持续时间有明显效果。 30 cases of infantile autumn and winter diarrhea were treated with Smectite and compared with that treated with minocycline or ribavirin.

The control group of 20 cases, markedly effective in 3 cases (15%), effective in 7 cases (35%), ineffective in 10 cases (50%), the total effective rate was 50%; average number of days after admission was 3.70 ± 1.22 days .
