Ac. Yao et al., CLINICAL AND LABORATORY OBSERVATIONS - PHOTOTHERAPY-ASSOCIATED CHANGES IN MESENTERIC BLOOD-FLOW RESPONSE TO FEEDING IN TERM NEONATES, The Journal of pediatrics, 124(2), 1994, pp. 309-312
Doppler blood flow velocity of the superior mesenteric artery was meas
ured preprandially and postprandially in 12 term neonates during photo
therapy and 4 hours after discontinuation of this therapy. The postpra
ndial increase in blood flow velocity was significantly less during th
an after phototherapy. We suggest that the phototherapy-induced periph
eral vasodilation may be responsible for diverting blood from the inte
stines and limiting the normal neonatal postprandial response.
