How will a staff nurse prepare normal saline from 10% Dextrose (per 100 ml) aEUR'
80 ml 10% dextrose in 20 ml NS 10% dextrose solution will provide lOg of glucose/100 ml. So, a solution is required which provides lOg of glucose. "The most commonly used I.V. fluid preparation in neonates is N/5, 10% dextrose" -So we need to provide a solution which provides 10g of glucose at a normal saline strength of N/5. - The solution that is similar to or close to the ideal I.V. fluid used in neonates is 80 ml 10% dextrose in 20 ml N.S. - 80 ml 10% dextrose provides 8g of glucose at normal saline concentration of N/5. - This concentration is closest to the ideal intravenous fluid required in neonates. 20 ml 10% dextrose in 80 ml NS would also provide 8gm of glucose but at a much higher concentration of normal saline than is usually administered in neonates. 40 ml 20% dextrose in 60 ml would also provide 8 gm of glucose, but here too the normal saline concentration is much greater than required in neonates.
