TLDR
Biochemical determinations showed that, in hypocalcemic infants, there were lower serum total calcium values at 8 hours of life, prior to the actual development of hypocalcemia at 29 hours, and three signs were significantly related to hypocalCEmia, namely, twitching of one or more extremities, high-pitched cry, and hypotonia.Abstract:
During an 8-month period, 37 of 124 infants (29.8%) admitted to a low birth weight (LBW) nursery developed hypocalcemia at a mean age of 29 hours. Ten factors were associated with hypocalcemia, three of which appear particularly relevant: (1) low gestational age (32 weeks or less) with appropriate birth weight, (2) low oral calcium intake, (3) correction of acidosis with NaHCO3. Biochemical determinations showed that, in hypocalcemic infants, there were: (1) lower serum total calcium values at 8 hours of life, prior to the actual development of hypocalcemia at 29 hours; (2) elevated serum phosphorus values; (3) acidotic values in the first hours of life, corrected to normal values at the time of hypocalcemia, and (4) lower serum protein values at 8 hours of life. Three signs were significantly related to hypocalcemia, namely, twitching of one or more extremities, high-pitched cry, and hypotonia.read more

Evaluation of Radiometer ICA1 as a routine instrument for serum ionized calcium and its application for whole blood capillary samples from newborn infants
TL;DR: The Radiometer ICA1 was evaluated with four sets of samples: a) 289 serum samples sent for routine analysis of ionized calcium, a reference set of serum samples from 40 healthy laboratory workers, c) 42 capillary whole blood samples from healthy full-term and d) six capillary entireBlood samples from pre-term infants.

Early neonatal hypocalcaemia.

TL;DR: In the authors' hospital early neonatal hypocalcaemia is now the major cause of low serum calcium in the neonatal period, and all sick low birth-weight infants should have daily serum calcium estimations carried out.

Hypocalcemia in infants of diabetic mothers.
TL;DR: It is speculated that relative maternal hyperparathyroidism leading to fetal hypoparathyroidistan may be a factor in the pathogenesis of neonatal hypocalcemia in infants of diabetic mothers.

Fetal body composition.
TL;DR: Quantitative estimates of fetal body composition can currently be achieved with recently developed and validated ultrasound tools, and their utility for the improved prediction of perinatal morbidity and mortality has not yet been rigorously examined.
