Abstract：PPN is one of the methods belongs to total parenteral nutrition and partial parenteral nutrition, mainly through peripheral veins to provide nutritional support. Although PPN has long history in clinics, there still have various viewpoints to many researchers, such as indications of PPN, reasonable periods of PPN applying, appropriate osmotic pressure and applying in geriatric patients and children. PPN is suitable for situation such as enteral nutrition couldn’t be established or insufficient enteral nutrition, central vein route couldn’t be established, parenteral nutrition with short time , low calorie and low nitrogen. PPN has the advantages of establishing infusion route of nutrition rapidly, costless than deep vein route, avoiding catheter related blood stream infection. Many researchers validated that PPN was safe and efficient during the period of perioperation. It has been accepted that osmotic pressure of parenteral nutrition was low and could be used in PPN. Fat emulsion had low osmotic pressure and could also lower the osmotic pressure of amino acid and dextrose, so it was benefit for PPN adding fat emulsion to parenteral nutrition. The incidence of complication was less for PPN than that of central vein route and had minimal damage to the body. The major complication relating to PPN are thrombotic phlebitis and leakage of fluid. It should be noticed that osmotic pressure should not be high at the time of PPN, the fat emulsion should be added in parenteral nutrition, according to the patients’ nutritional status and illness, applying duration of PPN should be shorten. Detection should be in progress regularly on the site of puncture during PPN to find the signs and symptoms of thrombophlebitis and processed in time.
