Peripheral parenteral nutrition in geriatric wards

Area of Science:

• Geriatrics
• Clinical Nutrition
• Internal Medicine

Background:

• Poor nutritional status is a major contributor to morbidity and mortality in the elderly population.
• Nutritional support is crucial during acute conditions and hospitalizations.
• Enteral nutrition is the primary choice when the gut is functional, but may be challenging in geriatric patients with delirium, agitation, coma, or pulmonary congestion.

Purpose of the Study:

• To evaluate the role of peripheral parenteral nutrition (PPN) as an alternative nutritional support method in elderly patients.
• To discuss the indications, practical application, and evidence supporting PPN in specific geriatric scenarios.
• To highlight PPN as a short-duration, complementary nutritional strategy when enteral feeding is contraindicated or difficult.

Main Methods:

• Review of current evidence and clinical experience regarding peripheral parenteral nutrition in acute geriatric care.
• Analysis of situations where enteral nutrition is contraindicated or impractical.
• Discussion of the benefits of PPN, including reduced central cannulation-related complications.

Main Results:

• Peripheral parenteral nutrition can be a viable option for short-term nutritional support when enteral feeding is not feasible.
• PPN may reduce complications associated with central venous catheterization, such as pneumothorax.
• While no evidence suggests PPN is superior to EN, it serves as an important alternative in specific clinical contexts.

Conclusions:

• Peripheral parenteral nutrition is a valuable complementary nutritional support method for short durations in elderly patients requiring supplemental caloric intake.
• PPN offers an alternative route when enteral nutrition is contraindicated, particularly in acute geriatric conditions.
• This approach can help mitigate risks associated with central line placement while ensuring nutritional needs are met.
