为研究静注钙剂对新生儿早发性低钙血症循环功能的影响,作者对1980～1981年住进某产院新生儿急救室内的16名未成熟儿进行观察。平均胎龄30.1±2.2周,出生体重1～2.06kg。年龄24～48小时。全部患有肺透明膜病。血钙4.2～7mg/dl。超声心动图检查排除器质性心脏病。其中8例先静注10%葡萄糖酸钙2ml/kg,1小时后再推注等量生理盐水,推注速度 To investigate the effect of intravenous calcium on the circulatory function of neonates with early-onset hypocalcemia, the authors observed 16 immature infants admitted to a neonatal emergency room in a hospital from 1980 to 1981. The average gestational age was 30.1 ± 2.2 weeks and the birth weight was 1 ~ 2.06kg. Age 24 ~ 48 hours. All suffer from hyaline membrane disease. Blood calcium 4.2 ~ 7mg / dl. Echocardiographic examination ruled out organic heart disease. Eight of them first intravenous injection of 10% calcium gluconate 2ml / kg, 1 hour after injection of equal volume of saline, bolus speed
