Background: Limited data support a recommended maximum osmolarity for administration of peripheral parenteral nutrition (PPN). In this retrospective, matched‐cohort study, we evaluated the incidence of phlebitis or infiltration associated with administration of PPN with an osmolarity >1000 mOsm/L vs ≤1000 mOsm/L. Materials and Methods : Patients ≤18 years old who received PPN in a 2‐year period were included in the study. Data related to patient demographics, PPN constituents, and adverse effects were analyzed. Results : A total of 352 patients met entry criteria. Overall, 139 (40%) patients experienced phlebitis or infiltration. There were no differences between patients who did or did not develop adverse events in terms of age or weight. Administration of PPN with osmolarity >1000 mOsm/L vs ≤1000 mOsm/L significantly increased infiltration (17% vs 7%; odds ratio [OR, 2.47]; 95% confidence interval [CI], 1.24–4.94; P = .01) and the combined composite end point of phlebitis or infiltration (45% vs 34%; OR, 1.65; 95% CI, 1.07–2.54; P = .02). In multivariate analysis, osmolarity >1000 mOsm/L vs ≤1000 mOsm/L was an independent risk factor for developing complications (OR, 1.67; 95% CI, 1.08–2.52; P = .02). Conclusion : Two of every 5 children experienced phlebitis or infiltration during administration of PPN. These adverse effects were more often observed in those who received PPN with osmolarity >1000 mOsm/L vs ≤1000 mOsm/L. With this high incidence of adverse effects, we recommend that if PPN is used, the osmolarity should not exceed 1000 mOsm/L. More important, PPN should only be used temporarily until central access is obtained.
