Effect of parenteral nutrition on oral intake.
Oral intake following a high density oral supplement (preload) is lower than that after a low density preload. We studied a similar effect of parenteral nutrition on oral intake. Twelve neurologically intact children (8-16 yr) with orthopedic problems and no concurrent illness were included in the study. As part of the inclusion criteria, all patients had documented energy intake for breakfast of +/- 10% on 3 consecutive days. On the fourth day parenteral nutrition equal to 50% of the mean energy intake for breakfast was provided for 4 hours before breakfast and energy intake measured. The composition of the parenteral energy was matched with that of the oral intake. The mean oral energy intake without (470 +/- 90 kcal) and with (458 +/- 64 kcal) parenteral nutrition preload was comparable (p > 0.05). Our conclusion is that parenteral nutrition does not affect oral intake in patients without underlying gastrointestinal disease.
