Where is PN provided?
PN can be provided in the hospital, in long-term care facilities, or at home. Sometimes people continue on PN after discharge from the hospital. Depending on the patient’s needs, different PN products are indicated. Because PN products are highly concentrated, they are typically delivered through central veins in the neck or chest. Delivery through peripheral veins in the forearm is used for shorter durations of PN.
Most lipid-based PN products provide essential fatty acids, one of the major nutritional components. Lipid sources used in PN include soybean oil, medium-chain triglycerides (MCT), olive oil, and fish oil.1
