本文对57例新生儿进行了心电图检查及血钙测定。结果表明:当心电图Q-Tc间期>0.45秒时有87％的病例血钙<1.88mmol/L,血钙值与Q-Tc间期呈负相关。新生儿低血钙与胎龄、体重有关,早产儿、低体重儿血钙平均值1.73mmol/L,足月儿血钙平均值1.95mmol/L,两组有显著性差异。有原发疾病的新生儿合并低血钙的发生率为63％,其中重症疾患的早产儿并发低血钙的发生率比足月儿高。提示对于早产儿、低体重儿尤其伴有重症疾患的应早制做心电图检查,有利于发现低血钙并进行早期治疗。
In this paper, 57 newborns were examined by electrocardiogram and serum calcium. The results showed that when the Q-Tc interval was> 0.45 second, 87% of the cases had a serum calcium <1.88mmol / L, and the serum calcium was negatively correlated with the Q-Tc interval. Neonatal hypocalcemia and gestational age, body weight, preterm children, low birth weight children with an average of 1.73mmol / L of calcium, serum calcium in term average of 1.95mmol / L, the two groups were significantly different. The incidence of hypocalcemia in newborns with primary disease is 63%, and the incidence of hypocalcemia in preterm infants with severe illness is higher than in full-term children. Tip for premature children, especially those with low birth weight infants with severe diseases should be made in advance of ECG, is conducive to the discovery of hypocalcemia and early treatment.
