新生儿低血钙于1900年已有报道,它并非由于维生素 D 缺乏所致。近30余年来逐渐对新生儿手足搐搦与新生儿低血钙之间的关系有所了解。本文就新生儿一周内发病的低钙血症的病因、症状及治疗等作一简介。一、胎儿期钙代谢的特点:1.钙:钙离子经胎盘可直接向母子体内两个方向传递。胎儿体内钙的贮存于孕30周时可达138毫克/公斤/日。孕36周时可达161毫克/公斤/日。至足月时可达成人体内贮存总量之半。一般情况下胎儿血钙值略高于母体血钙值。胎儿血钙大部
Neonatal hypocalcemia has been reported in 1900, it is not due to vitamin D deficiency. For more than 30 years gradually understand the relationship between neonatal tetany and neonatal hypocalcemia. This article on the pathogenesis of neonatal hypocalcemia within a week of etiology, symptoms and treatment for a brief introduction. First, the characteristics of fetal calcium metabolism: 1. Calcium: Calcium ions through the placenta can be transmitted directly to the mother and child in both directions. Calcium storage in the fetus up to 138 mg / kg / day at 30 weeks pregnant. Pregnancy 36 weeks up to 161 mg / kg / day. To reach full body half the total storage time. Under normal circumstances, fetal calcium value slightly higher than the maternal calcium value. Fetal blood calcium most
