Large volume parenterals can be classified into the following categories:

1. Hyperalimentation Solutions: These are used for administration of large amounts of nutrients such as carbohydrates and amino acids to a patient who is unable to take food orally for several weeks.
2. Cardioplegia Solutions: These are electrolyte solutions used in heart surgery to prevent ischemic injury to the myocardium. The electrolyte composition is intended to maintain diastolic arrest.
3. Peritoneal Dialysis Solutions: These are meant for continuous infusion into the abdominal cavity to aid removal of toxic substances such as drug overdose or to accelerate the normal kidney excretion in case of kidney dysfunction. These solutions contain glucose and have an ionic content similar to extracellular fluid.
4. Irrigating Solutions: These are used to irrigate, flush and clean body cavities (such as urinary bladder) and wounds.
