Values for some serum analytes in high-risk infants, two days postpartum

Area of Science:

• Neonatal intensive care
• Clinical chemistry
• Pediatric medicine

Background:

• Neonatal intensive care units (NICUs) manage diverse patient populations, including term and preterm infants.
• Asphyxia is a significant complication affecting neonatal health and requiring careful monitoring.
• Understanding biochemical profiles in neonates is crucial for effective clinical management.

Purpose of the Study:

• To establish baseline concentrations of 20 key analytes in neonatal sera.
• To investigate analyte variations in term vs. preterm infants.
• To assess the impact of asphyxia on neonatal biochemical parameters.

Main Methods:

• Analysis of capillary blood sera from 149 neonates using a continuous-flow (Technicon SMAC) analyzer.
• Measurement of 20 specific biochemical analytes.
• Comparison of analyte levels across different neonatal subgroups (term, preterm, asphyxia, no asphyxia).

Main Results:

• Quantified concentrations for 20 analytes in neonatal sera.
• Identified specific analyte values, particularly those related to renal function.
• Established reference ranges for various neonatal subgroups.

Conclusions:

• The study provides essential baseline data for neonatal biochemical analytes.
• These findings are valuable for evaluating therapeutic interventions and physiological changes in neonates.
• The data supports improved clinical decision-making in neonatal intensive care.
