目的分析孕期妇女补钙后血钙水平变化及对孕妇和胎儿的影响。方法选择初产健康孕妇600例,随机分为3组:A组未补充钙剂,B组孕妇从孕8个月起每日补充钙剂至分娩;C组孕妇从孕5个月起每日补充钙剂至分娩。測定不同孕期妇女的血钙值。在分娩后收集胎盘和脐血測量脐血钙,并測量新生儿的身长、体重,再分析不同血钙水平孕妇的妊娠结局。结果妊娠期血钙低于正常非孕期,随妊娠进展下降更明显(P<0.05),补充钙组血钙较对照组明显升高(P<0.05)。补钙组的临床缺钙症状明显低于对照组。结论孕妇补钙对新生儿的生长发育起积极作用,在妊娠期检测血钙水平是正确指导补钙的最好方法,它对母婴都是非常有益的。
Objective To analyze the changes of serum calcium level in pregnant women after calcium supplementation and their effects on pregnant women and fetus. Methods Sixty primiparous healthy pregnant women were selected and randomly divided into three groups: group A received no calcium supplementation; group B received daily calcium supplementation from 8 months of pregnancy until delivery; Group C pregnant women started daily from 5 months of pregnancy Calcium supplement until delivery. Determination of different pregnant women’s serum calcium value. Placenta and umbilical cord blood were collected after childbirth to measure umbilical cord calcium, and newborn’s body length and body weight were measured. Pregnancy outcomes of pregnant women with different serum calcium levels were analyzed. Results The level of serum calcium in pregnant women was lower than that in normal pregnant women (P <0.05). The serum calcium in calcium supplementation group was significantly higher than that in control group (P <0.05). Calcium group clinical symptoms of calcium was significantly lower than the control group. Conclusions Pregnant women’s calcium supplements play a positive role in the growth and development of newborns. The detection of serum calcium levels during pregnancy is the best way to correctly guide calcium supplementation. It is very beneficial to both mother and baby.
