本文通过对1987年1月～1992年1月收住院的1000名新生儿进行尿钙普查,凡尿钙“—”者均诊断为低钙血症。尿钙与血钙的关系为:尿钙“—”,血钙<1.75mmol/L;尿钙“+”血钙在1.75～2.25mmol/L;尿钙“++”,血钙在2.25～2.75mmol/L之间。结果发现本组新生儿低钙血症发生率为51.7％,低钙惊厥的发生率为7.3％。同时对低钙血症的病因亦根据尿钙检查结果.凡低钙血症者,给予静点钙剂3～7天,肌注VitD_3 20万U,尿钙全部转为正常,临床症状缓解至消失。低钙惊厥反复发作可致脑损伤,因此早期预防,早期治疗是关键。尿钙检查既方便,又无疼痛,并能反映体内血钙的情况,易被家长接受,能指导临床诊断和治疗。
In this paper, from January 1987 to January 1992 admitted to hospital 1,000 newborns urine calcium screening, urinary calcium “-” were diagnosed as hypocalcemia. The relationship between urinary calcium and blood calcium: urinary calcium “-”, serum calcium <1.75mmol / L; urinary calcium “+” blood calcium 1.75 ~ 2.25mmol / L; 2.75mmol / L between. The results showed that the incidence of neonatal hypocalcemia in this group was 51.7%, the incidence of hypocalcemia was 7.3%. At the same time the cause of hypocalcemia is also based on urinary calcium test results. Where hypocalcemia were given intravenous calcium 3 to 7 days, intramuscular VitD_3 200,000 U, all of the urine calcium to normal, clinical symptoms eased to disappear. Recurrent seizures of calcium can cause brain damage, so early prevention, early treatment is the key. Urine calcium examination is convenient, and no pain, and can reflect the situation of calcium in the body, easily accepted by parents, can guide clinical diagnosis and treatment.
