Equation of Pereira-da-Silva et al for Estimating the Osmolarity of a Neonatal Parenteral Nutrition Solution

Description

Pereira-da-Silva et al reported a simple equation for estimating the osmolarity of a neonatal parenteral nutrition solution. This can be useful when direct measurement is not available. The authors are from Universidade Nova de Lisboa in Portugal.

Selection: parenteral nutrition solution for a neonate

Parameters:

(1) glucose in g/L

(2) amino acids in g/L

(3) phosphorus in mg/L

(4) sodium in mmol/L

estimated osmolarity in mOsm/L =

= (8 * (amino acid)) + (7 * (glucose)) + (0.2 * (phosphorus)) + (2 * (sodium)) - 50
