Objective To investigate the clinical efficacy of polysaccharide iron combined with folic acid in treatment of anemia in gestation women and its effect on neonatal outcomes.Methods 82 cases of pregnant women with iron deficiency anemia were selected and randomly divided into two groups, each had 41 cases.All patients received discontinuation of iron supplementation two weeks pre-treatment, control group received compound ferrous sulfate and folic Acid Tablets (4 tablets, tid), the treatment group received with Iron Polysaccharide Complex Capsules (0.15 g~0.30 g, qd) and Folic Acid Tablets (0.4 m, qd) .Levels of serum Hb, SF and SI between two groups were compared, and the pregnancy outcomes, neonatal outcomes, and effect and safety were observed.Results Compared with pre-treatment, levels of RBC, HCT and Ret, levels of Hb, SF and SI in two groups were all increased (P<0.05),and those indexes in treatment group were higher than control group (P<0.05).Compared with control group, birth outcomes in cesarean section, the rate of postpartum hemorrhage and neonatal distress rate in treatment group were lower (P<0.05), scores of neonatal muscle tension, pulse, respiration, skin frowning were higher ( P <0.05 ), the total efficiency and safety were higher ( P <0.05 ). Conclusion Polysaccharide iron combined with folic acid in treatment of anemia in gestation women was accurate , it can significantly improve the neonatal outcomes.
