To determine the influence of peripheral parenteral nutrition (PPN) on the incidence of phlebitis and the effect of simultaneous infusion of lipid emulsion, 68 surgical patients were assigned randomly to 3 nutrition groups: (1) amino-acid 4% solution and dextrose 8% (AA + DX) + Intralipid (IL) 10% in the ratio 1.5:1 (2) AA + DX and IL 20% in the ratio 3:1 (3) AA + DX alone. Group 4 (control group) consisted of 25 patients receiving maintenance solutions and iso-osmotic drugs. No filters were used. ⋯ This is probably due to the lower osmolality and lower DX and K concentrations of the solution with IL 10%. Intralipid 20% does not have the same protective venous effect. The lower complication rate, the limited need for nursing, and lower costs compared to central parenteral nutrition, make PPN a safe nutrition technique for up to 10 days in patients needing no volume restriction.
