Gastric emptying in healthy newborns fed an intact protein formula, a partially and an extensively hydrolysed formula.
BACKGROUND & AIMS Gastric emptying ( GE ) is influenced by the type of nutrition . The objective of this study was to compare GE in infants fed an intact protein formula ( IPF ) , a partially hydrolysed formula ( PHF ) , and an extensively hydrolysed formula ( EHF ) .  METHODS This was a double-blind , r and omized , cross-over study . Following a fasting period of > or = 3 h , 20 healthy newborns were fed IPF , PHF , and EHF containing 50 microl (13)C-octanoic acid ( OA ) . Breath sample s were taken before feeding and every 15 min for 4 h thereafter . (13)C-OA  breath test was assessed by isotope-ratio mass spectrometry , and GE half-times ( t(1/2 ) ) were determined . RESULTS Seventeen infants with a mean gestational age of 37 wk ( range 28 - 40 wk ) and birth weight of 2698 g ( range 720 - 3690 g ) completed the study . At study initiation , the mean age was 31 d ( range 6 d-13 wk ) and the mean weight was 3466 g ( range 2100 - 5700 g ) . EHF emptied significantly faster than IPF and PHF ( medians 46 vs. 55 and 53 min , respectively , Wilcoxon , P<0.05 for both ) . There was no significant difference between GE of PHF and IPF ( Wilcoxon , P=0.2 ) . CONCLUSIONS EHF may be better tolerated by infants with GE problems
