Focus on Safety for Multi-Chamber Bag Parenteral Nutrition
March 2026
Recent ISMP and ASPEN guidelines highlight safety considerations around increasing use of multi-chamber bag parenteral nutrition (MCB-PN).
MCB-PN is different from the custom, compounded PN bags we’ve used for years. They’re manufactured bags with 2 or 3 chambers filled with separate macronutrients...amino acids, dextrose, and sometimes lipids.
Mixing is easier...you break internal seals to combine ingredients and activate the bag. Plus MCB-PN can be less costly and time-consuming.
