IV infusion of amino acids is accompanied by increased urinary excretion of the trace elements copper and in particular zinc, which should be taken into account in the dosing of trace elements, particularly during long-term IV nutrition. Hyperphenylalaninemia may occur in severely ill, premature infants. In these patients, monitoring of the phenylalanine level is recommended and the infusion rate adjusted as needed. Amino Acids IV infusion and 10% Glucose with Electrolytes should be used with caution in patients with diabetes mellitus, severe heart failure or with renal function in combination with fluid restrictions or oliguria/anuria of another origin. In patients with hyperglycemia, administration of exogenous insulin might be necessary. In severely malnourished patients refeeding carbohydrates can trigger thiamine (vitamin B1 ) deficiency syndrome. Those at high risk are patients with a history of alcohol abuse, anorexia nervosa, prolonged fasting or starvation and pregnant women with hyperemesis gravidarum. In this kind of patients, parenteral nutrition containing glucose should be given with caution and parenteral administration of thiamine should be considered before and during the administration of glucose. Monitoring of serum potassium and blood glucose is recommended if Amino Acids IV infusion and 10% Glucose with electrolytes is infused rapidly or in a large quantity. For patients with hypophosphatemia, an additional supply of phosphate is recommended.
