[Nycthemeral gastric secretion in children under parenteral feeding].
The nycthemeral basal gastric secretion was studied in 11 children under continuous or cyclic total parenteral feeding (TPF). The suppression of the prandial stimulation shows nycthemeral changes in the secretory flow with a nocturnal minimum and a diurnal morning maximum, independent of the TPF infusion-conditions. The role of the infused aminoacids and lipid emulsion, as well as the duration of TPF is suggested to explain the increase or decrease in the basal acid flow. The authors suggest that an H2 antihistaminic should be used if the morning secretory peak induces a significant functional impairment.
