The 2 meta-analyses also demonstrated that probiotics reduce the risk of death due to all causes , but do not have an effect on the risk of sepsis or death due to NEC .
Because of the limited data regarding synbiotics , the relationship between their use and clinical outcomes in preterm infants remains unclear .
The findings from the 2 meta-analyses of the effects of probiotic administration on the prevention of NEC show potential for such dietary supplementation .
BACKGROUND Uncertainty exists regarding the efficacy and safety of using probiotics and prebiotics in preterm infants .
AIM To review the evidence on the effects of administering probiotics and /or prebiotics to preterm infants .
Prebiotics Improve Gastric Motility and Gastric Electrical Activity in Preterm Newborns
The aim of this double-blind , r and omized , placebo-controlled study was to evaluate the effect of a prebiotic mixture on gastric motility in preterm newborns . After a feeding period of 15 days , gastric electrical activity was measured by electrogastrography , and the gastric emptying time was studied by ultrasound technique . No difference was seen in the daily increase of body weight , and no adverse events have been reported . The percentage of time in which propagation was detected in the electrogastrography signal was twice in newborns receiving formula with prebiotics  with respect to placebo , and the gastric half-emptying time was 30 % faster in the prebiotic group than the placebo group . Prebiotic oligosaccharides can modulate the electrical activity and the gastric emptying and may improve the intestinal tolerance of enteral feeding in preterm infants
