Blood urea nitrogen and serum bicarbonate in extremely low birth weight infants receiving higher protein intake in the first week after birth

Abstract

Objective: To determine correlation between early protein administration and serum blood urea nitrogen (BUN) or bicarbonate (HCO 3 À ) in extremely low birth weight (ELBW) infants during the first week of life.

Arterial Blood Carbonic Acid Inversely Determines Lactic and Organic Acids

“…This causes amino acid catabolism to be increased to meet energy needs, usually leaving insufficient protein for growth. A recent report on infants receiving such TPN described increases in blood urea in proportion to the amount of protein given, but no significant differences in bicarbonate [17]. This does not exclude serious organic acidosis from increased protein catabolism.…”

Determinants of Urea Production and Mineral Retention in Parenterally Fed Preterm Infants

“…This high protein content may make up for energy deficiency and still provide sufficient for growth. Infants receiving such TPN developed increases in blood urea in proportion to the amount of protein given, confirming that such regimens increase protein catabolism [14], and fail to prevent early postnatal growth failure in below 28 weeks gestation infants [12].…”

Computer Programming

“…Making this calculation is time‐consuming. There is also a need to include enteral as well as parenteral protein intake when configuring nutrition orders for neonatal patients to prevent excessive protein intake, as has been noted by Balakrishnan et al 20 The calculator program makes these calculations and orders the appropriate amount of AA in all orders.…”
