妊娠中晚期跟骨骨密度的超声测定与钙剂补充

The observation of ultrasonic calcaneum bone density in meta-late phase pregnancy

目的 超声骨密度仪测定妊娠中晚期孕妇跟骨骨密度。方法 对 2 80例不同孕期的孕妇用超声骨密度测定仪测量跟骨骨密度 (BMD) ,同期选择 30例正常健康非孕期妇女做对照组。结果 各孕期BMD较对照组明显下降 (P <0 0 1) ;各孕周之间BMD呈明显负相关 (P <0 0 5 )。结论 妊娠中晚期BMD下降 ,运用超声骨密度仪测定孕期BMD ,操作简单 ,安全无创伤 ,无辐射 ,能指导妊娠期孕妇及时补充钙剂。

Objective To determine the calcaneum bone density of pregnant women's in meta late-phase with ultrasonic bone density apparatus.Methods 280 cases gravidas in different gestation were determined in calcaneum bone density by using the apparatus.30 cases normal healthy non-pregnant women were selected as the control group.Results The calcaneum bone density in different gestation period descended obviously than the control group(P<0.01).The BMD in every pregnant week is negatively related(P<0.05).Conclusion BMD in meta-phase and late-phase is decline.To determine BMD of pregnancy by the ultrasonic bone density apparatus is simple,safe and no injury,no radiation.It can also direct the gravidas in different pregnancy to supplement calcium timely.
