Two- and Three-Chamber Bags
Bag systems with two and three chambers
Fresenius Kabi has offered two-chamber bags since the late 1980s and three-chamber bags since the late 1990s. These systems were developed in order to make parenteral nutrition easier to use and safer. At the same time they offer highly concentrated solutions that cover a patient’s daily need in one container. Shortly before administration, the nursing staff mixes the solutions stored in separate chambers with a few hand movements. Since these highly concentrated mixtures can only be stored for a few days, they had to be made at a hospital’s pharmacy before the introduction of multi-chamber bags.
Two-chamber bags form the basis for complete mixtures
Two-chamber bags contain an amino acid and a carbohydrate solution in separate chambers. Often the bags also contain electrolytes. Shortly before administration, the contents of the two chambers are mixed together. If a fat emulsion and vitamins and trace elements are added, the patient can receive all primary components of a parenteral nutrition from one container. The two-chamber bags are used if the amount and type of fat administered should be individually adjusted to the patient’s needs.
Three-chamber bags supply a whole day's needs
With three-chamber bags, all vital nutrients can be administered intravenously at the same time to cover a patient’s daily nutritional requirements. For stability, carbohydrates, amino acids and fats are stored in three separate chambers. The fluids are mixed shortly before use by opening the peel seams. Usually, three-chamber bags already contain electrolytes so that only vitamins and trace elements still need to be added.
Standard multi-chamber bag mixtures are sufficient for about 80 percent of all patients fed parenterally. About 20 percent require individual mixtures adapted to their special needs. Three-chamber bags are also suitable for long-term home nutrition due to their user-friendliness. They are used if a patient requires intravenous administration of nutrients due to a lack of intestinal function. All or some of the nutritional needs of a patient can be covered this way.
