Prematurity and Related Biochemical Outcomes: Study of Bone Mineralization and Renal Function Parameters in Preterm Infants

Table 2

Comparison of serum calcium, phosphorus, alkaline phosphatase, creatinine and electrolyte levels at 30–32 weeks and 34–36 weeks (Controls) of gestational age in preterm babies.

S. No	Parameter	Cases (𝑛=25)	Control (𝑛=25)	𝑃-Value
		30–32 weeks	34–36 weeks
(1)	Serum Calcium (mg/dL)	8.176±1.771	9.284±1.276	NS
(2)	Serum Phosphorus (mg/dL)	4.256±1.126	5.256±1.308	NS
(3)	Serum Alkaline Posphatase (IU/L)	503.48±164.37	322.08±80.07	<0.001
(4)	Serum Creatinine (mmol/L)	58.52±3.8	46.31±7.7	<0.001
(5)	Serum Sodium (mmol/L)	134.04±2.71	132.8±3.8	NS
(6)	Serum Potassium (mmol/L)	6.16±0.48	5.36±0.60	NS

This table shows that serum calcium & phosphorus levels is decreased (statistically insignificant) whereas alkaline phosphatase and creatinine levels are significantly and electrolytes are non-significantly increased at 30–32 weeks as compared to 34–36 weeks of gestational age in preterm babies.
