AIM: To explore the correlation between neonatal retinal hemorrhage(RH)and changes in umbilical artery blood gas analysis.METHODS: A total of 312 full-term neonates born in our obstetrics department from January 2019 to December 2021 were selected as the study subjects. According to the RetCam III fundus examination results, 245 neonates who did not experience RH were included in the control group, while 67 cases with RH were found to be included in the RH group. In addition, neonates were grouped into I degree group(n=20), II degree group(n=29), and III degree group(n=18)based on the degree of RH. General clinical data and umbilical artery blood gas analysis indicators between the RH group and the control group were compared; the levels of umbilical artery blood gas analysis indicators in neonates with different degrees of RH, the relationship between pH and RH degree, and the influencing factors of neonatal RH were analyzed.RESULTS: There was no obvious difference in maternal age, average gestational week, fetal gender, parity, gestational diabetes, fetal birth weight, and amniotic fluid between the RH group and the control group(all P>0.05), while there were obvious differences in delivery methods, gestational hypertension, forceps assisted delivery, neonatal asphyxia, and umbilical cord around the neck(all P
