Objective To characterize hemodynamic changes in celiac artery (CA) and superior mesenteric artery (SMA) in healthy term newborns during the first six hours after birth by means of Doppler ultrasonography.

Materials and methods The study included 30 healthy term newborns. The ultrasound examinations using Aloka α-10 were performed at the age of 2.4 and 6 hours after birth. The statistical analysis of Doppler variables was performed using the non - parametric Friedman test with all pairwise multiple comparisons. Presented results are shown as median (interquartile range).

Results A reversed blood flow in SMA, documented by negative values of end diastolic velocity (EDV) [- 10. 90 cm.s-1 (– 13. 21–0.00)], changed to positive during the first six hours after birth (7.08 cm.s-1 (6.29–13.48), p<0.001). In CA, EDV increased in this period, but negative values were not recorded [11. 83 cm.s-1 (9.34–13.86) and 18.03 cm.s-1 (14.20–27.57) ].

Conclusion Dramatic changes occur in splanchnic circulation during the first six hours after birth. In superior mesenteric artery, the negative diastolic blood flow turns to positive as a part of circulatory transition in the presence of a ductal steal.
