本文报道82例新生儿低钙血症,其中早产儿31例,占同期住院早产儿20%,足月儿51例,占同期住院足月儿4.2%;前者患病率明显高于后者。早产儿早发低钙血症与其病理生理特点有关;足月儿则由于围产窒息所致。晚发低钙血症主要因人工喂养乳品中钙磷比例不当;此外,光疗和纠酸也可诱发。作者认为早产儿血<1.8mmol/L、足月儿<2mmol/L作为低钙血症的诊断指标较适宜。并提出补钙的具体方案。
This article reports 82 cases of neonatal hypocalcemia, including 31 cases of premature children, accounting for 20% of hospitalized premature children in the same period, full-term children in 51 cases, accounting for 4.2% of hospitalized term full-term children; the former prevalence was significantly higher than the latter. Premature children with early onset of hypocalcemia and its pathophysiological characteristics; full-term children due to perinatal asphyxia. Late hypocalcemia mainly due to improper use of calcium phosphate in dairy products in an inappropriate proportion; In addition, phototherapy and acid correction can also be induced. The authors believe that premature children with blood <1.8mmol / L, full-term children <2mmol / L as a diagnostic indicator of hypocalcemia more appropriate. And proposed a specific program of calcium.
