Analysis of the Effect of Different Doses, Frequencies and Ways of Iron Supplements on Iron Deficiency Anemia in Pregnancy: a Randomized , Single Centered，Controlled, Single-blind Trial

YXL-KY-2023（006）

Subjects were tested for hemoglobin, ferritin, serum iron, transferrin saturation and reticulocyte count during routine prenatal examination at 24-26 weeks of gestation, and blood samples were taken for serum hepcidin detection in the laboratory and the values were recorded. Those who met the criteria were included in the study group, signed the informed consent form and randomized into groups, and were given different drug administration schemes (150mg orally every day, 300mg orally every day, 150mg orally every other day, 300mg orally every other day, intravenous). At the same time, each subject was given anemia diet education, and all subjects were given folic acid 400ug/d and vitamin C 0.5g/d orally during the treatment period. If the subjects were in the oral iron group, the same time of oral iron was determined as 20 o'clock ± 1 hour in the evening, and the oral iron was not taken with other drugs; If the subject is in the intravenous medication group, the medication is scheduled to be administered at a uniform time of 8 o'clock ± 1 hour in the morning. The above subjects were followed up. Hemoglobin, ferritin, serum iron, transferrin saturation and reticulocyte count were performed at 30-32 and 37 weeks of pregnancy and delivery, and blood samples were taken for serum hepcidin detection in the laboratory and the values were recorded. The adverse reactions were investigated with a questionnaire at the last prenatal examination before delivery. After full term delivery, the patient fills in the delivery information and enters it into the database. Finally, the data statistician and the above personnel used the blind method for statistical analysis and reached a conclusion.
