目的探讨孕期补钙对于预防妊娠期高血压疾病的效果。方法将我院2010至2011年间收治的92例孕期妇女随机分为观察组和对照组,每组各46例,观察组孕妇给予口服乐力钙,对照组孕妇不予以补钙,观察两组孕妇妊娠高血压的发生情况。结果观察组孕妇经口服钙剂后孕期血清钙含量为(2.46±0.19)mmol/L,显著高于对照组孕妇的(2.08±0.16)mmol/L,组间差异有统计学意义(P<0.05)。观察组孕妇妊娠高血压发生率为8.7%,显著低于对照组孕妇的32.6%,组间差异有统计学意义(P<0.05)。结论孕期补钙能够有效预防孕妇妊娠期高血压病的发生,对于保证母婴安全有重要的意义。 Objective To investigate the effect of calcium supplement during pregnancy on the prevention of hypertensive disorder complicating pregnancy. Methods 92 pregnant women admitted from 2010 to 2011 in our hospital were randomly divided into observation group and control group, with 46 cases in each group. The pregnant women in the observation group were given oral calcium and the control group were not given calcium supplementation. The two groups of pregnant women The incidence of pregnancy-induced hypertension. Results The level of serum calcium in pregnant women during pregnancy was (2.46 ± 0.19) mmol / L, which was significantly higher than that of pregnant women (2.08 ± 0.16) mmol / L, the difference was statistically significant (P <0.05 ). The incidence of pregnancy-induced hypertension in the observation group was 8.7%, significantly lower than that in the control group (32.6%). There was significant difference between the two groups (P <0.05). Conclusion Calcium supplement during pregnancy can effectively prevent the occurrence of pregnancy-induced hypertension in pregnant women, which is of great significance to ensure the safety of mother and infant.
