① Strong amino acid concentration.

② Nitrogen content

③ Amino acid types

④ the ratio of essential amino acids to non-essential amino acids (EAA/NEAA)

⑤ Branched chain amino acids (BCAA content)

⑥ Does it contain glucose and xylitol?

⑦ Inorganic salt species content

1, compound amino acid injection (18AA)

Cystine and high glycine may produce hyperammonemia; 5% sorbitol, high chloride ion content; Patients with severe hepatic and renal insufficiency, severe uremia and amino acid metabolism disorder are prohibited. Use with caution in patients with severe acidosis and congestive heart failure.

2. Compound amino acid injection (18AA-I)

No cystine, only cysteine, containing inorganic salts, without excessive glycine, can avoid hyperammonemia; Severe hepatic insufficiency, severe renal insufficiency, uremia and amino acid metabolism disorder are prohibited.

3. Compound amino acid injection (18AA-III, formerly 18AA-F)

High amino acid concentration, no chlorine and potassium ions, and extremely low sodium ion content; Patients with hepatic coma or tendency to hepatic coma, patients with severe renal failure or uremia, and patients with amino acid metabolism disorder are prohibited.

4. Compound amino acid injection (18AA-IV)

The amino acid concentration is low, and it contains glucose (7.5%), so diabetic patients should use it with caution.

5. Compound amino acid injection (18AA-V)

Contains xylitol (5%) and hydrochloride of various amino acids. The input of xylitol should not be higher than? 100 g (equivalent to 2000ml of this product).

18AA-I, 18AA-II, 18AA-III, 18AA-IV and 18AA-V are all nutritional 18AA preparations, which are suitable for most malnutrition. And the ratio should be appropriate, EAA/NEAA≈ 1. It usually consists of more than 14 amino acids.
