Here is how to figure out the D5W: 5% D5W means 5g/100ml D5W has 3.4kcal/g (memorize its a constant) To get kcal/L of D5W: 5g/100ml x 1000ml/1L x 3.4kcal/1g = 170kcal/L To get kcal/d of D5W: 100ml (not sure why this) x 24 hours = 2400ml/d ---> 2.4L/d 2.4L/d x 170kcal/L= 408 kcal/d of D5W Normal Saline: .9% NS= .9g/100ml 40% Na in NaCl .9g/100ml x 1000ml/1 L x 1000mg/1g = 9000mg/L 9000mg x .40= 3600mg/L 3600mg/L / 23 (molecular weight of Na) = 154 mEq/L of Na ½ Normal Saline: .45% ½ NS= .45g/100ml .45g/100ml x 1000ml/1 L x 1000mg/1 g = 4500mg/L 4500mg/L x .40 = 1800 mg/L 1800/23 (molecular weight of Na) = 77 mEq/L of Na mEq/day: ml x 24 hours / 1000= L/d

mEq x L/d Enteral Tube Feeding (When you are recommending or starting from scratch) 1. Get dosing weight (kg) * use current weight 2. Kcal goal: REE x AF x IF or 25-30kcal/kg (predictive equation to maintain weight) 3. Protein goal (% protein from kcal to pick formula)** .8g/kg 150:1 N balance All of the above give you grams of protein
