Preventive effect of simultaneously infused lipid emulsion against thrombophlebitis during postoperative peripheral parenteral nutrition.

A prospective, randomized study was conducted to determine whether simultaneous infusion of lipid emulsion with an amino acid-dextrose-electrolyte solution would reduce the incidence of thrombophlebitis (TP) during postoperative peripheral parenteral nutrition (PPN). Thirty patients who had undergone gastric resection for adenocarcinoma were randomly divided into two groups according to whether they were infused with 10% lipid emulsion (group A) or 5% glucose solution (group B) simultaneously with the amino acid-glucose solutions. The total osmolarity of the infusion solutions in each group was 853 mOsm/l. The incidence of complications due to TP, namely, redness and/or edema beneath the cannula insertion site and/or pain, was investigated. There were no differences in the background characteristics of the patients in groups A and B, except regarding concurrent resection of other organs (P = 0.03). The incidence of edema in group A was significantly lower than in group B on postoperative days 2 and 4, although there was no difference in the incidence of redness and pain between the two groups. These findings suggest that the simultaneous infusion of lipid emulsion has a preventive effect against TP during postoperative PPN, and may be a practical means of providing PPN after gastrointestinal surgery.
