Follow-up studies of children treated with a long-term intravenous nutrition (IVN) during the neonatal period.

The outcome of the 28 children treated with intravenous nutrition (IVN) for more than 4 wk during the neonatal period was investigated. Ten of the 28 children had a normal length of small bowel (group 1) and the other 18 children had a short bowel (group 2). Eight of these 28 children (4 in group 1 and 4 in group 2) died during or after cessation of IVN; three died from complication of IVN and 5 died from their initial disease. On physical examination, delay in catch-up growth was observed in the early postoperative period, particularly in children in group 2, but this diminished with time. Mental and emotional development showed both groups to be within the normal range, except for two children. Intellectual function was also normal in five children over the age of 4 yr who were examined. Hepatic dysfunction was noticed during IVN in 30.0% in group 1 and 66.7% in group 2, indicating that the longer the duration of IVN, the higher the incidence of liver damage. Furthermore, histologic abnormalities in these neonates lasted for a longer time. These results imply that long-term IVN during the neonatal period in surgical patients does not interfere with physical and developmental growth. However, careful and long-term follow-up of liver function after IVN is necessary.
