Abstract Objective To observe the change in main pulmonary artery blood flow between fetuses in the third trimester and neonates, and study the normal range and the change mechanism, providing basis for the early identification of neonatal disease. Methods The 315 objects were divided into three groups, fetuses in the third trimester (32-40 weeks) in group A, one day after birth in the group B, 28 days after birth in the group C. DMPA, VTI, QMPA were recorded for statistical analysis. Results The differences in DMPA(in the third trimester:(0.694±0.087) cm,one day after birth:(0.805±0.050) cm,28 days after birth:(0.910±0.050)cm,VTI[in the third trimester:(10.245±1.016) cm,one day after birth:12.604±0.969 cm、28 days after birth:15.297±1.129 cm]、QMPA [in the third trimester:(471.665±45.553) cm³/min,one day after birth:(857.730±76.584) cm³/min、28 days after birth:(1166.575±100.456) cm³/min)between the group A and group B, group B and group C, group A and group C were statistically significant (P<0.05). Conclusions Attention should be paid to the pulmonary hypoplasia if the diameter of the main pulmanary does not increase following the age. Be cautious of secondary pulmonary hypertension if the blood flow increases so obviously and of other diseases if the blood flow does not increase normally.
