Objective: By multichannel near-infrared spectroscopy, we studied if gestational age has any influence on preterm cerebral hemodynamics, during bolus feeding. Methods: Oxy-haemoglobin (HbO2), as cerebral blood flow estimate, and the ratio between HbO2 and total haemoglobin (HbO2/HbTot), as cerebral oxygenation estimate, were assessed in 40 stable premature infants, during a 10 min bolus feeding. Results: We found no effect of any of the gestational ages studied (25–34 weeks) either on cerebral blood flow or on oxygenation, during a bolus feeding procedure. Conclusions: Bolus feeding appears not to affect cerebral hemodynamics of uncritically preterm infants, irrespective of gestational age.
