本文观察了生态调节剂防治剂防治抗生素相关性腹泻（ＡＡＤ）的效果并调查抗生素对肠菌群的影响。结果表明预防组ＡＡＤ的发生率（２．９％）明显低于对照组（８．６％），预防组肠道菌群失调较轻而对照组肠道菌群明显失调；应用生态调节剂治疗ＡＡＤ有效率为８０．３％，治疗后ＡＡＤ病人肠道菌群失调有明显好转。提示生态调节剂能维护肠道微生态平衡减少ＡＡＤ的发生。
In this paper, we observed the effect of ecological regulator on the prevention and treatment of antibiotic-associated diarrhea (AAD) and investigated the effect of antibiotics on the intestinal flora. The results showed that the incidence of AAD in prevention group (2.9%) was significantly lower than that in control group (8.6%). The prophylaxis group had less intestinal flora imbalance but the control group had obvious imbalance of intestinal flora. AAD efficiency was 80.3%, after treatment, AAD patients with intestinal flora significantly improved. It is suggested that the ecological regulator can maintain the intestinal microflora balance and reduce the occurrence of AAD.
