Choice of intravenous infusion route for parenteral nutrition / 中华临床营养杂志

ABSTRACT

Parenteral nutrition can be delivered by peripheral venous catheterization (PVC) and central venous catheterization (CVC).While PVC is the first choice for parenteral nutrition in most cases,CVC represents a better option in the case of high osmotic pressure (＞900 Osm/L) or prolonged nutritional support (＞ 14 days).Percutaneous central venous catheterization through subclavian vein is advisable for critical patients,but its indwelling time should be kept under 30 days.Peripherally inserted central catheterization,with low risk of lesion and infectious complications,is recommended by Chinese guidelines for elderly patients.Implanted port provides reliable rout for patients who need long-term intravenous treatment,including parenteral nutrition.Patients with such device enjoy more freedom in daily life and better quality of life.When choosing intravenous infusion route,we need to take into consideration the patient's condition,desire and treatment time.Standardized application of catheterization is key to the safety of its use.
